2018 Environmental Performance Index: Air quality top public health threat

and has no comments yet.
The 2018 Environmental Performance Index (EPI) finds that air quality is the leading environmental threat to public health. Now in its twentieth year, the biennial report is produced by researchers at Yale and Columbia Universities in collaboration with the World Economic Forum. The tenth EPI report ranks 180 countries on 24 performance indicators across 10 issue categories covering environmental health and ecosystem vitality. Switzerland leads the world in sustainability, followed by France, Denmark, Malta, and Sweden.Switzerland’s top ranking reflects strong performance across most issues, especially air quality and climate protection. In general, high scorers exhibit long-standing commitments to protecting public health, preserving natural resources, and decoupling greenhouse gas (GHG) emissions from economic activity.

How Far Can Technology Go To Stave Off Climate Change?

and has no comments yet.
The U.S. now has two coal-burning power plants that avoid dumping carbon dioxide into the air. Petra Nova in Texas and Kemper in Mississippi use technology to stop CO2 in the smokestack and before combustion, respectively. Unfortunately, that makes two out of more than 400 coal-fired power plants in the U.S., the rest of which collectively pour 1.4 billion metric tons of the colorless, odorless greenhouse gas into the atmosphere each year. Even Kemper and Petra Nova do not capture all of the CO2 from the coal they burn, and the captured CO2 is used to scour more oil out of the ground, which is then burned, adding yet more CO2 to the atmosphere. The carbon conundrum grows more complex — and dangerous — with each passing year.
