Travel emissions drop added to lockdown methane surge, says new research

Envirotec Magazine

Reduced transport emissions led to lower levels of hydroxyl radicals – which could be said to act like a detergent to remove methane from the atmosphere, researchers say. Until now, the causes of the 2020 surge in methane – second only to carbon dioxide as a driver of climate change – had been unclear. ppb in 2019.

Meet the startup producing oil to fight climate change

Grist

To prevent the most devastating effects of climate change, it’s essential to cut greenhouse gas emissions by phasing out fossil fuel use. One of the company’s founders, Kevin Meissner, wanted to build a shrine of sorts to human-induced climate change. They can pay to destroy methane leaking from a landfill.

CowCredits: Mootral aims to cut cattle burps through carbon offset offer

Business Green

in backing for its plan to fund farmers' use of methane-reducing cattle feed through CO2 offsets. Companies and individuals may soon be able to pay cows to burp less in return for carbon offset credits, under plans being developed by Swiss-British agritech firm Mootral to fund the use of methane-cutting cattle feed on farms.

Could green hydrogen be key to a carbon-free economy?

GreenBiz

The last 15 percent of the economy is hard to clean up — aviation, shipping, manufacturing, long-distance trucking," Fakhry said in an interview. Hydrogen derived from methane — usually from natural gas, but also coal and biomass — was pioneered in World War II by Germany, which has no petroleum deposits. Green hydrogen can do that.".

Meat emits around a third of global emissions of methane, and action to cut this greenhouse gas has been identified by the UN and world leaders as the quickest route to slowing global heating. The science is also uncertain around soil’s ability to store carbon, which can be easily undone through erosion, or changes in land use or the weather.

Carbon offsets alone won’t make flying climate-friendly

It’s also terrible for the climate. In the presence of the sun’s rays, nitrogen molecules set of a chain of reactions that produce ozone and destroy free-floating atmospheric methane. Some of these reactions, like the methane destruction, help cool the Earth. It’s tough to pin down the meaning of all this chemistry.
