One of recommended carbon offsets is BURN. If I understand correctly, BURN provides households with more efficient stoves, which allows them to use less wood or charcoal for cooking. So carbon that would otherwise be in the atmosphere as CO2 remains in the form of trees. On the other hand, Giving Green does not recommend forestry offsets:
Of particular concern is “permanence”, which refers to the fact that in order to keep CO2 out of the atmosphere, trees must stay alive for many years. This adds an additional layer of uncertainty to any forestry project that is nearly impossible to resolve. To make things more complicated, the relationship between forests and global warming is complicated, and there is some controversy in the scientific community as to how much changing forest cover affects the temperature of the planet.
This seems inconsistent to me. Am I missing something?
