A group of 10 global airlines, announced today the formation of the Aviation Climate Taskforce (ACT), a new non-profit coalition, aimed at tackling the challenge of reducing carbon emissions in aviation.ACT founding members include Air Canada, Air France-KLM, American Airlines, Cathay Pacific, Delta Air Lines, JetBlue, Lufthansa, Southwest Airlines Co., United Airlines, and Virgin Atlantic, and the alliance was launched together with Boston Consulting Group (BCG).The aviation industry has come under scrutiny as a significant source of greenhouse gas (GHG) emissions, responsible for 2-3% of global emissions, with that figure potentially rising dramatically over the coming decades if no action is taken. Several initiatives are being pursued in order to address the climate impact of the indus...

Analysis of the total carbon dioxide emissions of countries since 1850 has revealed the nations with the greatest historical responsibility for the climate emergency. But six of the top 10 have yet to make ambitious new pledges to cut their emissions before the crucial UN Cop26 climate summit in Glasgow in November.The six include China, Russia and Brazil, which come only behind the US as the biggest cumulative polluters. The UK is eighth and Canada is 10th. Carbon dioxide remains in the atmosphere for centuries and the cumulative amount of CO2 emitted is closely linked to the 1.2C of heating the world has already seen.At the UN negotiations, historical emissions underpin the claims for climate justice made by developing nations, along with the disparity in wealth of nations...
Scientists using artificial intelligence to sift through around 100,000 climate studies were trying to put a number on how many people in the world were already experiencing the impacts of the climate crisis.Instead, they discovered something else: there is a worrying inequality in the world of climate science.The shoreline of Kadavu Island in Fiji, where rising sea levels have led to coastal erosion.Asanka Brendon Ratnayake/The New York Times/ReduxClimate change studies are twice as likely to focus on wealthier countries in Europe and North America than low-income countries like those in Africa and the Pacific Islands. That blind spot is a problem, as the Global South is and will continue to be more profoundly impacted by the climate crisis than wealthier countries.The ability to link the...
