"First emissions mechanism established for aviation", 9 Nov 2016

Carbon emissions from aviation are growing faster than any other sector. In an effort to address the problem, the International Civil Aviation Organisation (ICAO) approved the world’s first global emissions reduction scheme last month. The Carbon Offset and Reduction Scheme for International Aviation (CORSIA) is a market-based mechanism in which carbon emissions are offset through the purchase of credits, leaving aviation emissions to remain – at least on paper – at 2020 levels…without effective measures, aviation could account for about 22% of all emissions by 2050, according to projections from Greenovation Hub, an environmental non-governmental organisation…

The main challenge in curbing aviation emissions is that improvements in technology, operational efficiency and the development of sustainable alternative fuels will be unable to keep pace with passenger growth, meaning an increase in overall carbon emissions. Andrew Murphy, aviation officer with Transport & Environment, a sustainable transportation body, told chinadialogue: “For the next few years, it’s expected that passenger demand will grow around 4-6% a year, while efficiencies will improve by about 1-2% a year.”…
