Human activity has increased the direct warming effect of carbon dioxide (CO₂) in the atmosphere by 50 percent above pre-industrial levels during the past 25 years, according to NOAA's 10th Annual Greenhouse Gas Index . In 2015, the global average CO₂ concentration reached 399 parts per million, increasing by a record amount of almost 3 ppm. From the end of the Ice Age to the beginning of the industrial era, atmospheric carbon dioxide remained remarkably stable at 278 ppm.

Operational measures in line with new air traffic management systems, as well as new technological concepts, all have the potential to continue reducing these CO 2 emissions. The Commission for Aeronautical Meteorology (CAeM) supports aviation stakeholders in their efforts to operate under changing climate conditions.
