Oil palms only grow in humid tropical environments. Environments that when left undisturbed would be tropical rainforest. Decoupling palm oil from deforestation is therefore very hard. Certified sustainable palmoil is simply from farmland that the farmers have proved not to have been deforested recently but that same land still has the potential to return to tropical rainforest after restoration.
Regarding America specifically probably only Hawaii could support it. But land there is scarce and is used for much higher value crops like fruit crops. Harvesting palm oil is also quite labor intensive since the fruit bunches are harvested manually. It therefore does not make economic sense to grow it in countries with high wages.












Since oil palms only grow in humid tropical environments it really comes down to which land we value the most. By using 3 hectares in Europe we could save 1 hectare of land in rainforests. What is worth more, 1 hectare rainforest in Indonesia or 3 hectares of native woodland in Europe? It’s not really clear cut. One could argue that 1 hectare of rainforest is more valuable because of the higher biodiversity. However there is not one natural answer to this question and ultimately subjective.
