23 Jan 08. Aviation industry pledges to play full part in climate change fight. The Society of British Aerospace Companies (SBAC) has reacted to the publication of the European Commission’s proposals on addressing climate change by re-stating its pledge to do its part in the work to reduce greenhouse gases. The UK aviation industry has made great strides in improving fuel efficiency and is already committed, through its Sustainable Aviation initiative that was launched in 2005, to achieving a 50% reduction in CO2 emissions from new aircraft by 2020. The Government’s Stern report confirmed that the industry is on course to meet these targets.
