Study: 2/3 of aviation climate impact due to emissions other than CO2

Green Car Congress

This new study is based on a thorough review of a decade of research on aviation emissions. It makes an important contribution to the scientific understanding we have of the role of aviation for climate change—an understanding decision-makers and politicians may need on the way to achieving the goals of the Paris Agreement.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Green Car Congress

Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Emission rates of BC in the year 2000 by region, indicating major source categories in each region. Black carbon aerosol plays a unique and important role in Earth’s climate system. Source: Bond et al.

IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

The UN Intergovernmental Panel on Climate Change (IPCC) released a policymaker’s summary of Working Group III’s (WG III) latest report showing that despite a growing number of climate change mitigation policies, annual anthropogenic GHG emissions grew on average by 1.0 GtCO 2 eq (1.3%) per year from 1970 to 2000.
