Overview
Climate change activism focused on US federal policy can potentially reduce levels of greenhouse gases (GHGs) in the atmosphere by impacting the likelihood of climate bills passing in the House and Senate, or by affecting executive or regulatory policy. We developed a simple cost-effectiveness analysis (CEA) model that assesses activism’s contribution to GHG emissions. In this model, we focused on activism’s potential impact on two types of bills: a bipartisan bill and a progressive-influenced bill passed along party lines. After testing various scenarios in our CEA (e.g., Very Pessimistic to Optimistic), we found that donating to climate change activist groups could be highly cost-effective in reducing GHGs, which we measured in terms of CO2-equivalent (CO2e). Namely, our Realistic case estimated that activism could remove CO2e at a cost of $0.15 per metric ton. In other words, a dollar spent on activism could remove more than 6 metric tons of CO2e. In general, the cost per change in metric ton of CO2e ranged from $0.07 to remove a ton of CO2e to actually adding a ton of CO2e for every $1.04 spent on activism. We explore these pathways for negative effects, and conclude that they are highly unlikely.
Our Realistic scenario’s estimate of $0.15 per metric ton of CO2e is within range of Founder’s Pledge’s estimate of the Clean Air Task Force’s (CATF) estimated cost-effectiveness, which ranges from $0.03 to $5.50 per metric ton of CO2e avoided. [1] This suggests that activism could be nearly as effective as a best-in-class insider policy advocacy organization in reducing CO2e. However, donating to activism runs the very small risk of either having a negative effect or no effect at all on CO2e levels. For this risk to occur, (1) bipartisan climate bills would need to be highly impactful and (2) activism would also need to reduce the likelihood of bipartisan bills being passed. We believe that the former is somewhat unlikely and that the latter is unlikely, making the overall risk low.
We conducted our CEA by (1) estimating how much CO2e could be averted through bipartisan and progressive climate bills between 2022 and 2030, (2) assuming the change in probability of these climate bills being passed due to activism, (3) calculating an expected value for activism in terms of CO2e averted, and (4) using our estimates and assumptions to calculate cost-effectiveness. Given the large uncertainty on the different values we used in our analysis, our estimates should be viewed as rough, indicative estimates.
Note that this analysis is funded by an EA Funds grant, whose main purpose was to improve our research on activism. We welcome feedback from the EA community, so that we can continue to improve this work over time.
Methods
High-level overview of our modeling strategy
To determine the cost-effectiveness of activism in removing CO2e from the atmosphere, we developed a stylized situation that includes two types of bills: a modest bipartisan bill and an ambitious progressive-led bill. [2] The key dynamics from our model comes from the assumption that progressive activism will have a positive impact on the progressive bill passing, but an ambiguous impact on the bipartisan bill passing. We also assume that there are more opportunities for a bipartisan bill to pass than a progressive one.
We estimated activism’s cost-effectiveness by taking the steps detailed in Figure 1 and described below.

Parallelograms indicate the final model outputs. Values related to the bipartisan bill are yellow while values related to the progressive bill are blue.
Inputs
Our model included four different types of inputs:
The progressive and bipartisan bills’ reductions in CO2e emissions from 2022 to 2030,
The effect of activism on the likelihood of either bill passing,
The ratio of bipartisan bill cycles to progressive bill cycles per decade, and
The cost of activism.
Reduction in CO2e emissions from 2022 to 2030
We used the current (September 2021) draft infrastructure bill and budget reconciliation bill as examples of bipartisan and progressive bills, respectively. We considered the infrastructure bill to be bipartisan because it passed with a 69-30 vote in the Senate, meaning that 19 Republican Senators joined the entire Democratic Caucus in passing this bill. [3] Compared to the infrastructure bill, the upcoming reconciliation bill is expected to be more progressive and contain more ambitious pro-climate policies because it only needs a simple majority to pass in a Democrat-controlled Senate.
We used existing models for the bills’ climate provisions to estimate their CO2e reductions from 2022 to 2030 compared to business-as-usual (BAU). We focused on this time period because we assumed that progressive legislation would only occur under a Democratic trifecta, which has occurred about once every decade for the past forty years. In other words, if a progressive bill does not pass now, it will not have a chance to pass until Democrats control both the White House and Congress, estimated to be around 10 years from now. (We project climate impacts for 8 years as a conservative estimate.)
The effect of activism on the likelihood of either bill passing
The effect of activism on the likelihood of either bill passing was the most difficult parameter of our model to estimate and is highly subjective. To estimate this, we first assumed that climate change activism would be progressive. We then assumed that activism would increase the likelihood of a progressive bill being passed because of their similar alignment, and that this is the explicit policy goal of many progressive activist organizations. For a bipartisan bill, we allowed activism to have positive or negative effects of passing. For example, activism could have a positive effect if progressive pressure moves the position of the center or spurs action by the right to stave off more progressive legislation later. Conversely, it could have a negative effect if activism polarizes climate change as an issue such that it cannot get right-wing support or if it prevents compromise. Additionally, activists may advocate for a more progressive bill in place of the bipartisan bill; this could therefore reduce the bipartisan bill’s likelihood of being passed. To account for uncertainty in our estimates, we examined a range of probabilities, which we labeled as our Very Pessimistic, Pessimistic, Realistic, and Optimistic scenarios.
Ratio of bipartisan bill cycles to progressive bill cycles per decade
Because bipartisan bills are likely up for consideration more often than progressive bills, we needed to weight activism’s expected value by this difference in frequency. We therefore assume that there will be multiple bipartisan bill opportunities for every opportunity for a progressive bill.
Cost of activism
We used the Sunrise Movement’s finances from 2015 to 2020 as a proxy for the cost of climate change activism. We used the Sunrise Movement because it is one of the most successful climate change activist groups. Although our model uses the Sunrise Movement’s finances, it is not explicitly intended to be an analysis of the Sunrise Movement’s cost-effectiveness (though we will likely adopt a version of it to model Sunrise’s impacts).
Expected values
We computed the expected value for the two bills by multiplying each of their probabilities by their CO2e reduction. We weighted activism’s expected value for the bipartisan bill by multiplying its unweighted expected value by the ratio of bipartisan bill cycles to progressive bill cycles per decade. We summed the bills’ expected values to compute activism’s total expected value.
Outputs
We found the per unit cost of changing CO2e by dividing the cost of activism by its expected value. The change in CO2e per dollar was the reciprocal of the per unit cost.
Detailed overview for estimating activism’s cost-effectiveness
Details on how we estimated activism’s cost-effectiveness are as follows:
Inputs
Reduction in CO2e emissions from 2022 to 2030
We estimated each bill’s CO2e reduction by either using models produced by research groups or by conducting back-of-the-envelope calculations with publicly available data. We compared each bill’s CO2e reduction against its respective BAU case. Exact details on our methods and assumptions can be found in our CEA model.
Bipartisan climate bill
We used climate provisions from the 2021 infrastructure bill as a proxy to estimate how much CO2e could be averted due to a bipartisan climate bill. For our CEA, we included the following climate provisions from the infrastructure bill:
Electrifying transit and school buses,
Expanding the US network of electric vehicle (EV) chargers,
Capping abandoned gas/oil wells to prevent methane leaks,
Reducing emissions near ports and airports, and
Extension of 45Q tax credit (from previous bipartisan bill)
We excluded some of the infrastructure bill’s climate provisions from our analysis. For example, we could not find enough publicly available information on the bill’s funding for battery research and development (R&D). The degree to which battery R&D would reduce CO2e emissions was also unclear. By excluding these climate provisions, we may have underestimated how much the bipartisan bill actually reduced CO2e emissions.
Additionally, the current bipartisan bill includes funding for R&D for carbon capture. As it is very difficult to estimate the impacts of R&D, we instead included a similar measure from a previous bipartisan bill, which extended the 45Q tax credit for carbon capture; CO2e reductions due to the 45Q tax credit were more straightforward to estimate than the provisions in the current bill.
Progressive climate bill
To estimate how much a progressive climate bill could reduce CO2e emissions, we used the 2021 budget reconciliation bill as a proxy. Policy proposals that we included in our proxy progressive bill included:
Incentivizing a transition to clean energy in the power sector via a Clean Energy Payment Program (CEPP),
Electrifying homes through a heat pump rebate program, and
Providing EV tax incentives.
As with our infrastructure bill analysis, we did not include all of the reconciliation bill’s proposed climate policies. For example, we excluded proposals related to land conservation because they were too complex to model and because their inclusion in the reconciliation bill was uncertain. We assumed that excluding these proposals was reasonable because based on media coverage of the reconciliation bill, clean electrification appeared to be its most important climate provision by a wide margin. [4] It therefore seemed likely to us that CEPP would dominate the total amount of CO2e reduced and that the other proposals would be less important to our calculations.
The effect of activism on the likelihood of either bill passing
Bipartisan climate bill
For our Realistic and Optimistic scenarios, we assumed that activism would increase the likelihood of a bipartisan bill being passed. For the Very Pessimistic and Pessimistic cases, we assumed that activism would either decrease this same probability or have no effect at all. Ultimately, we estimated probabilities of −5%, 0%, 1%, and 5% for the Very Pessimistic, Pessimistic, Realistic, and Optimistic cases, respectively. We selected these values by first assuming that the Realistic case would increase the probability of the bipartisan bill being passed by a very small percentage. We then used that percentage to anchor our estimates for the remaining cases.
Although we examined a case in which activism would have a negative impact on bipartisan action, we believe that the likelihood of the Very Pessimistic case actually happening is very low. For example, activist pushback against modest climate reforms may be viewed negatively but can in fact have a positive effect on climate. For instance, the activist-led “No Climate, No Deal” campaign in 2021 led to sixteen US Senators refusing to vote on the infrastructure bill unless it included bold climate action. Ultimately, the bill was passed in the Senate with the inclusion of various climate provisions. This kind of brinksmanship likely results in bipartisan bills having stronger climate provisions, but also increases the chance that no bill passes at all. However, we are not aware of any cases where progressive pressure has actually derailed a bipartisan climate bill from passing.
Progressive climate bill
We assumed that activism would increase the likelihood of a progressive bill passing. We assigned probabilities of 0.5%, 0.5%, 5%, and 10% for the Very Pessimistic, Pessimistic, Realistic, and Optimistic cases, respectively. These values were informed by our research and expert interviews. While impossible to know for sure, most insiders have told us that the climate provisions in the reconciliation bill would not have happened without the rise in activist policy organizations (such as the Sunrise Movement) over the last couple of years.
Time-dependency of bills being passed
The probability of either a bipartisan or progressive bill being passed (and therefore the influence of outside organizations) is highly time-dependent because it strongly depends on the political climate. Namely, the likelihood of a climate bill being passed is probably reduced during years in which either the House, Senate, and/or Presidency are under Republican control. We selected our probabilities based on the current political climate.
Ratio of bipartisan bill cycles to progressive bill cycles per decade
For both the Very Pessimistic and Pessimistic cases, we assumed that bipartisan bills with climate provisions would be proposed once every Congressional cycle (once every two years) while progressive bills would be proposed once every time Democrats control the House, Senate, and White House (roughly once every decade). For the Realistic case, we assumed that bipartisan bills would be proposed every presidential term (once every four years) instead of once every congressional cycle. As for the Optimistic case, we assumed that bipartisan bills would occur twice as frequently as progressive bills.
Cost of activism using the Sunrise Movement’s finances
We used the Sunrise Movement’s revenue from 2015 to 2020 as a proxy for activism’s estimated cost. We selected the Sunrise Movement as an archetype because it is one of the most successful climate change activist groups in recent years. We chose this time period because it covered the beginning of the Sunrise Movement’s finances through the end of 2020, which is roughly when Democrats secured the House, Senate, and White House and therefore increased the likelihood of substantive climate policy being passed. Activist groups, such as the Sunrise Movement, likely used their funding raised up until that point to advocate for passing pro-climate policies under the Democratic trifecta. We calculated the Sunrise Movement’s total revenue from 2015 to 2019 using publicly available tax returns. We estimated its 2020 revenue using its self-reported budget for that year.
Expected values
We computed activism’s unweighted expected value by multiplying the changes in probabilities for the two climate bills by their estimated reductions in CO2e relative to BAU. We weighted activism’s expected value for the bipartisan bill by multiplying it by the ratio of bipartisan bill cycles to progressive bill cycles per decade. We found activism’s total expected value by summing the two bills’ expected values.
Outputs
To determine activism’s cost-effectiveness in reducing CO2e emissions, we divided activism’s total expected value by its estimated cost. We computed the cost-effectiveness both in our CEA model and in an additional Guesstimate spreadsheet, which allowed us to assign ranges of values and probability distributions for each input. The Guesstimate model uses Monte Carlo simulations with 5,000 samples per metric. Information on how we set this model’s bounds can be found in the Guesstimate spreadsheet.
Results
Reductions in CO2e
Relative to BAU, the climate provisions in the bipartisan bill are predicted to reduce CO2e emissions by about 160 million metric tons between 2022 and 2030. In comparison, the progressive bill is predicted to reduce CO2e emissions by about 3,200 million metric tons over the same time period. The CEPP provision alone is expected to contribute to 92% of the progressive bill’s emissions reduction between 2022 and 2030.
Cost-effectiveness of activism on climate change
According to our CEA model, the cost of changing CO2e emissions is expected to be -$1.04, $1.53, $0.15, and $0.07 per metric ton for the Very Pessimistic, Pessimistic, Realistic, and Optimistic cases, respectively (Table 1). This is equal to a change in CO2e of −0.96, 0.65, 6.70, and 13.72 metric tons of CO2e per dollar for the Very Pessimistic, Pessimistic, Realistic, and Optimistic cases, respectively. The Very Pessimistic case’s negative signs indicate that CO2e emissions will increase under this scenario.
Table 1: Cost-effectiveness of activism on removing CO2e from the atmosphere
Very Pessimistic | Pessimistic | Realistic | Optimistic | |
Cost per change in metric ton of CO2e (positive equals decrease in CO2e) | -$1.04 | $1.53 | $0.15 | $0.07 |
Change in CO2e per dollar (metric ton of CO2e/$) | -0.96 | 0.65 | 6.70 | 13.72 |
When we used Guesstimate, the 50th percentile for cost per change in CO2e is predicted to be about $0.20 per metric ton of CO2e (Figure 2). The 95th percentile is predicted to be $1.62 per metric ton while the 5th percentile is predicted to be -$0.19. Because negative values are predicted to occur below the 6th percentile, our “Very Pessimistic” scenario is highly unlikely to happen.

Our Guesstimate model predicted that the 50th percentile for change in CO2e per dollar is about 4.3 metric tons per dollar. The 95th percentile and 5th percentile are predicted to be about 22.7 and −0.1 metric tons per dollar, respectively.

Discussion
Comparing activism’s cost-effectiveness against insider policy advocacy
It seems likely that donating to effective climate change activism organizations could be as cost-effective as donating to a best-in-class insider policy advocacy organization. Namely, our cost-effectiveness estimates for activism were on par with CATF’s cost-effectiveness. According to Founders Pledge, CATF realistically reduces CO2e at a cost of $0.29 per metric ton with a range of $0.03 to $5.50 per metric ton for its Optimistic and Pessimistic cases, respectively. There is therefore some overlap in cost-effectiveness between activism and CATF. Although our model shows that activism could could potentially have an adverse effect, this risk though is very low given that negative values for the cost per change in CO2e were below the 6th percentile in our Guesstimate model.
Uncertainty in the CEA model
As with many models, our CEA model has many sources of uncertainty and should be taken as indicative only. Below, we list some particular factors where our model may have erred.
Change in probability of climate bills passing due to activism
The most uncertainty in our CEA model came from our estimates for how much activism changed the probability of climate bills passing. Our model is most sensitive to activism’s effect on the progressive bill. For example, it is possible that activism could only increase the likelihood of a progressive bill passing by 0.5% instead of 5% under the Realistic case. This would increase our cost-estimate to $1.23 per metric ton, which is more than a seven-fold increase in price. Our cost-estimate was less sensitive to changes to the bipartisan bill’s probability of passing. For example, changing this probability for the Realistic case from 1% to 0.01% did not affect the cost per change in metric ton of CO2e.
Reductions in CO2e emissions
There is uncertainty on how much activism actually reduces total CO2e emissions. For example, our CEA likely underestimated the total reduction in CO2e emissions because we did not include all of the infrastructure bill and reconciliation bill’s climate provisions. It is also possible that the studies we used to estimate long-run impacts of the bills could have had incorrect assumptions.
In particular, it is possible that we underestimated the bipartisan bill’s reductions in CO2e emissions. Namely, some of its provisions, such as R&D, will play out over long time periods with great uncertainty. Because we focused on emissions just from 2022 to 2030, this dynamic was excluded from our model. But we agree it could have significant long-term effects, and also very successful technologies could spill over globally and have outsized impact. However, it is difficult to know if this is the case and model it with any kind of confidence.
We found that changing the amount of CO2e emissions only had a moderate effect on activism’s cost-effectiveness. For example, if we had underestimated reductions in CO2e emissions by 50% for both bills, our corrected cost-estimate for the Realistic case would decrease from $0.15 to $0.10 per metric ton, which is a decrease of about 33%. Conversely, if we had overestimated reductions by the same percentage, the corrected cost-estimate would increase to $0.30 per metric ton. This doubled cost is still relatively inexpensive and remains comparable to CATF’s cost-effectiveness.
Estimated cost of activism
We assumed that the Sunrise Movement’s revenue would be an appropriate proxy for estimating activism’s cost and that its revenue would be equal to its budget in 2020. However, we are unsure of our assumptions’ accuracy. This impacts our cost-estimates because our cost-estimates are directly proportional to activism’s cost. For example, doubling the cost of activism would double the Realistic case’s cost-estimate. Even if the cost of activism were ten times greater than what we estimated, the cost per change in activism would only reach $1.49 per metric ton of CO2e, which is still fairly inexpensive.
Possible negative impacts
There is a chance that activism could have a negative impact on GHG emissions. Per our model, this would require (1) bipartisan bills to have a high impact relative to progressive bills and (2) activism to have a negative impact on bipartisan bills being passed. Because both of these requirements seem unlikely to us, the overall likelihood of activism having a negative impact on climate change is probably low.
We admit it is possible that we may be underestimating the long-term effect of bipartisan provisions, given that we may be underestimating the climate impact of R&D, which has been included in recent bipartisan bills. For instance, R&D investment into carbon capture could significantly reduce the technology’s cost over time. However, even if bipartisan bills are more impactful than what we estimated, this is not enough to make the effect of activism negative. For this, we also need to assume that activism decreases the change of bipartisan bills passing, which we think is unlikely.
Conclusion
According to our CEA model, donating to climate change activism could be highly cost-effective in reducing CO2e emissions. For example, under the Realistic scenario, donating to climate change activism could reduce CO2e emissions at a cost of $0.15 per metric ton, which compares favorably with estimates of the most cost-effective charities.

Thanks for doing this. It’s really interesting to see someone try to quantify the effects of activism. A few questions:
1. Can you further explain your estimate of a 0.5% − 10% higher chance of a bill passing because of climate activism?
2. Does that number claim that the Sunrise Movement in particular increased the chance that much, or that all activism (compared to some world with no active pro-climate grassroots movement) increased it that much? If the latter, is this being divided by the Sunrise Movement’s budget, or to something else? Is the claim that the Sunrise Movement represents the majority of climate activism, so that its budget is a fair proxy for the budget of the entire cause area?
3. Is the claim that the marginal effect increases linearly? IE if the existing Sunrise Movement increases the chance of the bill 5%, then increasing their budget by 10% would increase the chance of a bill by 5%*10% = 0.5%? If so, what’s the thought process behind this assumption?
Hi Scott, thanks for your questions! Good questions, let me try some responses.
This is clearly the most difficult parameter to measure. We thought .5-10% represented a reasonable yet conservative range of potential values. I’d say “conventional wisdom” (ie what quite a number of the people we’ve spoken with have argued, but certainly not everyone agrees) is that you can draw a pretty straight line between the recent work of policy-focused climate activism groups like Sunrise and subsequent placement of climate as a high priority for the Biden administration. All of that being said, we agree that it’s relatively arbitrary. As we move forward to look at specific organizations, we’ll try to do a bit more work to get more reasonable values for these parameters. But it’s not clear how much better (if anything) we’ll be able to do.
We were trying to make this CEA a bit more general but it was clearly calibrated on Sunrise. I think you should interpret the model as representing a single, effective activism organization with a specific budget. So if we were trying to use the model to hone in on Sunrise’s impact, we’d say that for Sunrise’s budget of ~25 million over 5 years, we think this caused X% increase of a broad, progressive bill being passed. You could also extrapolate this to the movement in general, but then you’d use a larger budget and a larger % change.
We aren’t making that claim, but if you wanted to extrapolate this model to a future marginal increase in spending, then yes you’d need this assumption. I’d agree this is dodgy, but also I’m not sure the best way to extrapolate a total effect to marginal effect. Probably would just have to do some kind of discounting to account for diminishing marginal effects. This is something we should definitely think about, so thanks for bringing it up.
Thanks Dan and Kim for this analysis, super interesting to see this work done! A main question and a couple of smaller ones:
Do you think a group as big as Sunrise is still a marginal and counterfactually impactful donation for EAs to give to now? As my thinking around social movement organisations like Sunrise is that they’re usually quite funding constrained early on but once they “blow up”, raising more money for them isn’t too challenging. Given that Sunrise has a fairly large supporter base, it seems they could raise donations quite easily from a pool of people who wouldn’t otherwise give to EA-aligned charities, so it’s hard to see the marginal value an EA donor would have here. What are your thoughts on the above? And if you’ve spoken with Sunrise/a similar activist group, what would they do with additional funds?
Specifically, who did you speak to and who do you consider insiders and experts in this case? You’ve probably seen this document already by Founders Pledge on evaluating policy organisations but they have an interesting hierarchy of desirable sources so curious to see where yours ranked on that. Also did you push them much for numerical estimates or do you have any transcripts of those interviews?
How come you selected the same probability for activist influence on a progressive bill for both the pessimistic and very pessimistic cases? Seems a bit counter-intuitive to me.
4. Another question about these probabilities are: Have you thought about deriving them from Sunrise’s to date impact on influencing policy and how successful they’ve been so far? Or referencing to other activist organisations globally to see if there’s some base rate for activist success on influencing policy (I appreciate this is a huge job!).
Hi James,
Thanks for your feedback! It was really helpful and gave us a few things to think about. A few responses:
Marginal benefit: These are all good questions. They are ones we didn’t tackle in our general activism model laid out here (which was inspired more by looking backward at Sunrise’s previous activities) , but that we are thinking about as we consider whether or not to recommend Sunrise this giving season. Sunrise says that additional funds (especially to the c3) will be used to grow their movement in both size and effectivness. I think is is a compelling argument that Sunrise’s movement would be a lot more powerful if it could recruit more active, passionate members. However, I agree it’s not clear whether there may be declining marginal returns to money at this point and/or if Sunrise could easily raise all the money it needs from mainstream donors. (Both those points are intertwined.)
Expert interviews: We’ve spoken with philanthropists (who do this kind of thing for a living) as well as a spectrum of folks who work across the climate sphere (private sector, think tanks, government, nonprofits, etc). No, we haven’t pushed for numerical estimates and no we don’t have transcripts, but we do have notes. I’ll agree that this kind of information can be pretty unreliable, and be very influenced by the biases of the people you speak with. For the case of Sunrise in particular, we’re working on getting more opinions to hone our estimates. Thanks for attaching that document from FP- I’d seen it before but it was helpful to re-read as it gave me some ideas for how to push some of this estimation forward.
There are a few variables which change in the different scenarios, and we didn’t necessarily change all variables between all scenarios. The pessimistic and very pessimistic scenarios both have a very low (.5%) influence of activism on the progressive bill, but have different assumptions on activism’s influence on the bipartisan bill.
For this model, we have been “deriving them from Sunrise’s to date impact on influencing policy and how successful they’ve been so far”, though we understand that even doing this takes pretty great assumptions. We haven’t tried to reference to other activist orgs globally- we think it would get even less accurate if we try to move to different contexts.
Thanks again!
Is progressive activism for the climate more cost-effective than nonpartisan activism (such as by Citizens’ Climate Lobby)?
HI Michael, thanks for the question!
We haven’t tried to do an in-depth analysis of Citizen’s Climate lobby, though we did do a shallow dive on them last year. I think in theory it would be great if we could find an organization doing high-impact, centrist activism, but I haven’t seen it. CCL is an interesting model and they have had a lot of success, but they have been really focused on a carbon tax, which doesn’t seem to have much leverage in DC recently. So I think that blunts their effectiveness.
That being said, a carbon tax just came up in the discussions for the first time in a while, so perhaps there is more potential to CCL’s approach than I originally thought.
I’m super grateful for the work y’all are doing. It seems likely that a more sophisticated analysis of this topic, in conjunction with the studies that estimate the expected costs of each metric ton of CO2e, may show that a climate activism intervention is one of the most impactful sectors for our donations. This may be particularly true when considering the long-term/existential risks that the economic impact studies neglect.
If these estimates are in the right ballpark and someone creates the equivalent of a carbon offset credit certificate that the public/corporations find legitimate enough, I think this could funnel a lot of money into far more effective emission reduction schemes than traditional carbon offset programs. Plus, such an offset protocol wouldn’t suffer from many of the shortcomings of current offset credit approaches, which most left-leaning people/organizations find too apolitical, unfair, and parochial.
Here are some additional reasons why these figures may be overly conservative on the full benefits of climate activism:
1. Reductions in CO2e are only one direct benefit of reduced fossil fuel emissions. Another well-studied, direct, non-politicized effect of these efforts is the reduction of particulate matter, which Open Philanthropy is considering as one of its high-impact sectors because of its enormous harms on human health.
2. It seems likely that many of the lowest-hanging fruits in the climate activism fight may have already been achieved in the American context (i.e., the impact of any additional donations may be much lower than the average stated). However, because (1) a metric ton of CO2e has the same effect regardless of where it is emitted, (2) one can presume a lower cost of activism for any assumed increase in the likelihood of success for any given bill in developing nations (e.g., India), and (3) the highest-impact, lowest-hanging fruits may still be available in developing nations, we can assume that climate activism may have even lower costs in the international context. Further, international areas are even more dependant on particulate-matter-producing coal plants, making their positive impact significantly higher.
3. These estimates only consider the federal-level effects of climate activism, but the Sunrise Movement’s scattered grassroots approach undoubtedly has large effects on local and state climate policies.
Super excited for this research to get increasingly sophisticated, to expand to the international context, to include particulate matter, and to be combined with cost estimates that include both short- and long-term risks!
Hello Manny, thanks for the encouragement and good ideas! Some quick responses to your points:
Yes, reduction in particulate matter is super-important, and we haven’t incorporated this into our CEAs. Measuring the social cost (of both CO2 and particular matter) is pretty tough/controversial, but in the future we’d like to incorporate this kind of thinking into our models.
Yes, this is a good point. We’ve focused on the US because we have a comparative knowledge from our understanding of the US context, and also as a large emitter changes in US federal policy can have really big effects. But it wouldn’t surprise me if there are great opportunities in other contexts. As Giving Green grows, we hope to expand our research to more contexts.
Yes, this is certainly true, and would mean our estimates of overly conservative.
Finally, I’d say that I don’t really think that the carbon markets are a promising form of funding for activism. Corporation (who are the primary buyers of carbon credits) seek certainty of emissions reductions so that they can make their “carbon-neutral” commitments (no matter how sketchy this may be in practice.) I don’t think many corporations are going to have hunger for less certain and politically controversial activist “offsets”. I think this space will have to be funded by philanthropy.
