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.

BNEF, Snam, IGU report finds global gas industry set to resume growth post-pandemic; low-carbon technologies for long-term growth

Green Car Congress

However, the resulting low gas prices, as well as clean air and climate policies, will promote further switching to gas from other more polluting energy sources, such as oil and coal. Ample natural gas resources exist to support demand growth, but greater gas infrastructure development is needed to support growth in the medium term.

LKAB identifies Europe’s largest deposit of rare earth metals in Lapland; Per Geijer

Green Car Congress

Sweden-based international mining and minerals group LKAB has identified significant deposits of rare earth elements in the Kiruna area in the far north of Swedish Lapland (some 200 km north of the Arctic Circle). This is good news, not only for LKAB, the region and the Swedish people, but also for Europe and the climate.

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.
