When I encounter news like this I cannot help but think of Greenwashing. Giant corporations like Unilever and Nestlé committing a billion dollars to protect tropical forests can sound like buying a way out of bad press.
But then I tell myself to be less cynical and appreciate that these organizations have a huge lever to do less of [wrong thing] and more of [right thing] and that we do indeed want them to be incentivized in that direction. Being suspicious enough to dismiss any positive initiatives as marketing ploy, does the opposite. It makes everyone less likely to get out of the bad equilibrium of unsustainable exploitation on the one hand, and righteous environmentalists scolding them on the other.
So, kudos to everyone behind the LEAF coalition! May you have a good plan for achieving the most good with the money.
