Robust CO2 Offsetting

In Nature of February, an article by German, Dutch and Swedish researchers analyse current schemes and practices in offsetting schemes for aviation emissions. Aviation CO₂ emissions are estimated to grow by 360° between 2000 and 2050. The authors show that the global scheme adopted by the International Civil Aviation Organisation will only compensate for the emissions increase if robust criteria for the eligibility of offset credits are adopted. Use of offset credits from already implemented projects, will not yield notable additional reductions, nor will it offer incentives for new investments. They recommend allowing only new projects that meet robust criteria for real and additional emission reduction.
