Yes, I agree. There are arguably some corporate initiatives that are trivial PR stunts, or attempts to pre-empt government intervention; but $2B is a big chunk of change, and this doesn't seem like either. From Amazon's perspective, this a good move (and I'm sure as much in the interests of their bottom line as long-term planetary altruism). But from a citizen's perspective, we shouldn't rest on our laurels and assume that corporations and private investment will solve the problem on their own.
