Concept airplane could eliminate 95 percent of aviation’s NOx emissions, reducing early deaths from plane air pollution, about 16,000 per year, by 92%
Generally, the environmental cost of flying is high. At cruising altitude, planes emit a steady stream of nitrogen oxides (NOx) into the troposphere, which eventually convert into ozone and fine particulates, an MIT press release noted. According to the U.S Energy Information Administration, an independent statistic and analysis organization, ozone in the troposphere is harmful to human health and adds to the climate crisis. WWF estimated …
Pursuing greener and more efficient airplane designs
By Ben Morris & Theo Leggett BBC https://www.bbc.com/news/business-51751984 (also see article below – ridehailing reduces airport parking by 7%) At an undisclosed location Airbus has spent months testing a radical looking plane.

World’s Richest 10% Emit up to 43% of the Carbon: Flying is most of it. Researchers say we need sufficiency not just efficiency + more attention to emissions from air and land transport, and to the fairness and equity of it all
The affluent citizens of the world are responsible for most environmental impacts and are central to any future prospect of retreating to safer environmental conditions. Any transition towards sustainability can only be effective if far-reaching lifestyle changes complement technological advancements. The wealthiest 0.54%, about 40 million people, are responsible for 14% of lifestyle-related greenhouse gas emissions, while the bottom 50% of …
Green bailouts: relying on carbon offsetting will let polluting airlines off the hook
May 27, 2020, Ben Christopher Howard, Doctoral Researcher in Nature-based Solutions, University of Birmingham The coronavirus pandemic has grounded thousands of aircraft, contributing to the largest-ever annual fall in CO₂ emissions. At some point though, the planes will soar again and with them, global emissions. Most airlines in the UK have committed to achieving net zero carbon emissions by 2050. From 2026, …
