Charles He answers How much money donated and to where (in the space of animal wellbeing) would “cancel out” the harm from leasing a commercial building to a restaurant that presumably uses factory farmed animals?

Charles_Dillon had a great answer.

Answering the question of “Where to donate” that you asked:

TLDR; Consider donating to the EA Animal Welfare Fund, because I think they are more able to fund nimbler, high-impact projects, and the fund is well advised and connected to the entire farm animal welfare movement.

Explanation:

I think one reason to donate to the Animal Welfare Fund is that they are more able to support nimbler projects. For example, The Humane League is a great organization to donate to and has a great track record of success. Now, the funding landscape for farm animal welfare has some structure now, so an established organization such as the The Humane League and their important initiatives seem to get funding somewhat reliably. In contrast, it’s still hard for smaller projects to get started. The Animal Welfare Fund can make this happen.

Secondly, the job of the EA Animal Welfare Fund is to find and donate to good causes. They exist to serve you and use your donation money well. They grant to the Humane League and others. Their fund managers are extremely experienced, respected and aggressive in maximizing impact. Based on this, it seems to make sense to delegate granting to such an organization.
