tax-exempt 501(c)3 nonprofits in the US are required to file IRS form 990[1] which sheds some light on the financials of the organization. it doesn't mean that the organization is run efficiently or puts money to good use, but it does increase transparency[2]

Yeah, to be clear, I'm not demanding it of you. If you just happen to know of something then I'm hoping you'll share.

And yes, but slightly more. I want to know that the carbon credits are real, i.e. that I'm actually offsetting.
