Create an international cap-and-trade network where American companies can purchase "pollution credits" from Indonesian farmers. The credits would be used to clear land sustainably. The scheme would be designed in such a way that the mitigated Indonesian pollution far outweighs the American pollution enabled through such a scheme. Naturally, it would be cheaper for Indonesian farmers to clear land sustainably than for American companies to pollute less (some are hitting a wall with current anti-pollution technology).
After Indonesia reaches a certain GDP-per-capita, its own companies would be subjected to progressively higher restrictions on pollution. At that point, Indonesian companies themselves would be paying companies in less developed nations (Laos, Rwanda) for the right to pollute.
> Farmers are clearing land the fastest way they know how to cash in on growing demand for palm oil, which is used in half of all supermarket products, from chocolate to shampoo.
It always gets down to money. We need to find financial carrots and sticks to affect change whilst keeping in mind that carrots are always better than sticks.
