Through a series of complex chemical reactions (i.e., “carbonation”), CO2 can reduce concrete’s pH and increase its porosity – ultimately impairing the overall strength and durability of concrete. The phenomenon is hastened in humid climates and in large cities or industrial areas where fossil fuels are likely to be burned at higher rates.

EPA chief Scott Pruitt announced Monday that he will sign the paperwork to repeal the Clean Power Plan, an Obama administration rule to combat climate change rule by reducing greenhouse gas emissions from coal and natural gas power plants.

Greenhouse gas emissions across the European Union (EU) last year were 22 percent lower than 1990 levels, according to a new report from the European Environment Agency (EEA).

In response to expectations that the oil industry report on climate change issues, the international global oil and gas industry association IPIECA has developed a new Climate Change Reporting Framework.

The Commercial Aviation Alternative Fuels Initiative (CAAFI®) recently celebrated its 10th anniversary working toward sustainable jet fuels. The Federal Aviation Administration (FAA) helped found the coalition a decade ago to promote the development and deployment of alternative jet fuels that sustainably reduce lifecycle carbon emissions and local pollution around airports. These innovative new fuels also improve energy security, minimize fuel price volatility, and enhance rural development.

The American Public Health Association voiced deep disappointment today over the Supreme Court’s decision to stay the Clean Power Plan pending the outcome of ongoing litigation.

A new report says the stage is set for some dramatic confrontations over proposed regulations that will pit the White House and the EPA against a Republican Congress.

Among the new federal regulations expected to be issued today is one which is being challenged on the basis of the way the social cost of the carbon rule was calculated for it.
