Shall the American Association of Geographers Endorse Carbon Offsets? Absolutely Not!

Offsetting is widely embraced as a market-based solution to global warming. Governments, universities, and businesses of all sorts have pledged to achieve "net zero" greenhouse gas emissions partly or entirely through offsetting projects, many of which rely on so-called nature-based solutions (NBSs). Offsets are meant to compensate for damage caused by emissions from one place by absorbing or preventing the release of an equivalent amount somewhere else. At best, offsetting results in no change in total emissions, but as theory predicts and experience shows, that best result is rarely attainable. Meanwhile, both land-based and industrial offsets legitimize continued emissions. There is active debate in Paris-pact talks and in climate politics more broadly over how much fossil-fuel industries and industrial countries will be allowed to delay real climate action by representing offsets as if they were emissions reductions. The American Association of Geographers should not contribute to this illusion by endorsing offsetting. Instead we should take steps to reduce our own emissions and speak out clearly when our work has bearing on policy decisions and public perceptions about the climate crisis.
