Carnegie study finds climate impact of particulates varies greatly depending on where the pollution originated

Green Car Congress

Yet, aerosol emissions from Europe, the United States, and China are declining, while aerosol emissions from India and Africa are increasing. For example, their models show that aerosol emissions from Western Europe have 14 times the global cooling effect that aerosol emissions from India do. This work is part of a larger $1.5-million

Gravity Batteries, Green Hydrogen, and a Thorium Reactor for China

Cars That Think

This article, by researchers at PARC and the University of Washington, is one possible answer. Most of the world’s hydrogen comes from deeply polluting methods. The pumps tap into vast stores of groundwater that lie not too far underground and cover much of sub-Saharan Africa. She looked at a recent study out of the U.S.

Test of Planet-Cooling Scheme Could Start in 2022

Cars That Think

The quantity of calcium carbonate to be released—about 1 kilogram—won’t be enough to trigger any measurable cooling, and it roughly equals the particle pollution that a large commercial airliner releases every minute of flight, says. Faye McNeill’s group at Columbia University. There were nearly 40 million such flights in 2019.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

This article shows that including offsets in climate change legislation would likely make an emissions program more cost-effective by: (a) providing an incentive for non-regulated sources to generate emission reductions; and (b) expanding emission compliance opportunities for regulated entities. Benefits to Developing Countries.

Perspective: The UN Approval Process for Carbon Offsets

Green Car Congress

This article discusses the process by which the UN approves carbon offsets and the flaws associated with this process. Renergie is in the process of transferring its proven renewable energy technology worldwide by working closely with developing countries in Latin America, the Caribbean, Asia and Africa. THE APPROVAL PROCESS.
