UCL-led study finds climate impact caused by growing space industry needs urgent mitigation

Green Car Congress

The rapidly growing space industry may have a greater climate effect than the aviation industry and undo repair to the protective ozone layer if left unregulated, according to a new study led by UCL and published in the journal Earth’s Future as an open-access paper. The space industry is one of the world’s fastest growing sectors.

The ESA’s goal is to grow as a space fairing nation and compete side by side with the United States, Russia, and China on all fronts – including the possible creation of their own domestic human spaceflight program. ESA hopes to fill these gaps while tackling the societal, economic, and security challenges that come along with it.

International study identifies 14 key measures to reduce methane and black carbon emissions; reduction in projected global mean warming of ~0.5 °C by 2050

Green Car Congress

Circle areas are proportional to values for (A and B) climate change, (C and D) human health (values for population over age 30), and (E and F) agriculture. Their potential climate impact was assessed by using published global warming potential (GWP) values for each pollutant affected. Source: Shindell et al. Click to enlarge.
