EDIT: Oh! It was rockstrom, but the actual quote is: “The richest one percent must reduce emissions by a factor [of] 30, while the poorest 50% can actually increase emissions by a factor [of] 3” from Johan Rockström at #COP26: 10 New Insights in Climate Science | UN Climate Change.
There he is talking about fair and just carbon emissions adjustments. The other insights he listed have economic implications as well, if you’re interested. The accompanying report is available here.
The quote is:
“Action on climate change is a matter of intra- and intergenerational justice, because climate change impacts already have affected and continue to affect vulnerable people and countries who have least contributed to the problem (Taconet et al., Reference Taconet, Méjean and Guivarch2020). Contribution to climate change is vastly skewed in terms of wealth: the richest 10% of the world population was responsible for 52% of cumulative carbon emissions based on all of the goods and services they consumed through the 1990–2015 period, while the poorest 50% accounted only for 7% (Gore, Reference Gore2020; Oswald et al., Reference Oswald, Owen, Steinberger, Yannick, Owen and Steinberger2020).
A just distribution of the global carbon budget (a conceptual tool used to guide policy) (Matthews et al., Reference Matthews, Tokarska, Nicholls, Rogelj, Canadell, Friedlingstein, Thomas, Frölicher, Forster, Gillett, Ilyina, Jackson, Jones, Koven, Knutti, MacDougall, Meinshausen, Mengis, Séférian and Zickfeld2020) would require the richest 1% to reduce their current emissions by at least a factor of 30, while per capita emissions of the poorest 50% could increase by around three times their current levels on average (UNEP, 2020). Rich countries’ current and promised action does not adequately respond to the climate crisis in general, and, in particular, does not take responsibility for the disparity of emissions and impacts (Zimm & Nakicenovic, Reference Zimm and Nakicenovic2020). For instance, commitments based on Nationally Determined Contributions under the Paris Agreement are insufficient for achieving net-zero reduction targets (United Nations Environment Programme, 2020).”
Whether 1.5 is really in reach anymore is debatable. We’re approaching an El Nino year, it could be a big one, we could see more heat in the atmosphere then, let’s see how close we get to 1.5 GAST then. It won’t be a true GAST value, I suppose, but there’s no way we’re stopping at 1.5 according to Peter Carter:
“This provides more conclusive evidence that limiting to 1.5C is impossible, and only immediate
global emissions decline can possibly prevent a warming of 2C by 2050”
and goes on from there.… He prefers CO2e and radiative forcing rather than the carbon budget approach as mitigation assessment measures. It’s worth a viewing as well.
There’s quite a lot to unpack in just these two sources, if you’re interested.
Then there’s Al Gore at the World Economic Forum, who drops some truth bombs: “Are we going to be able to discuss… or putting the oil industry in charge of the COP … we’re not going to disguise it anymore”
OLD:I believe it was Rockstrom, though I’m looking for the reference, who said that citizens of developed countries needed to cut their per capita carbon production by 30X, while in developing countries people could increase it by 3X. That’s not a quote, but I think the numbers are right.
That is a counterpoint to the analysis made by some climate economists.
When I find the reference I’ll share it, because I think he was quoting an analysis from somewhere else, and that could be useful to your analysis given the sources you favor, even if you discount Rockstrom.
