This article explores using global market mechanisms to go beyond the greenhouse gas reduction targets set by certain countries. It suggests ways to achieve extra reductions in greenhouse gases, either by ensuring a net benefit to the atmosphere or through contributions from countries hosting emissions offset projects. The researchers found that stricter rules for giving credits for emissions reductions could lead to extra environmental gains in the short term. Alternatively, giving fewer credits for offsets could work as a less effective, but still helpful, approach to fixing flaws in the offset market. The study shows that making additional efforts beyond formal agreements can lead to more greenhouse gas reductions, at least in certain situations.
