The International Civil Aviation Organization (ICAO) finalized an agreement to cap the aviation industry’s CO2 emissions at 2020 levels. Due to the cross-border nature of aviation, this sector, which is responsible for 2 percent of all GHG emissions globally, was excluded from the Paris Agreement in 2015. Although the agreement’s mandatory phase begins in 2027, more than 60 countries will voluntarily participate in the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) beginning in 2021. CORSIA is a market-based measure capping emissions at 2020 levels. Airlines that exceed the emissions cap can offset their excess CO2 in two ways.… [more]

The focus of the United Nations Framework Convention on Climate Change (UNFCCC) originally was the reduction of greenhouse gas emissions, as well as emissions associated with land-use change and forestry. However, by the 2000s scientists and policymakers realized that emissions targets were too low to avoid serious negative impacts, necessitating the development of adaptation responses as a complement to mitigation. In the past few years, it has become clear that historical emissions have “locked in” a certain level of climatic change, making some serious impacts unavoidable. Moreover, the feckless response of the world in arresting emissions makes even graver unavoidable… [more]
