The Advantages of Portland-Limestone Cement| Concrete

PLC is a slightly modified version of portland cement that improves both the environmental footprint and potentially the basic performance of concrete. It is now described in ASTM and AASHTO specifications and is used just like traditional portland cement in mix designs. It can be made at any portland cement manufacturing plant.

Offsetting carbon emissions, one ton at a time | Penn Today

The idea of a historical carbon footprint is very important." Penn's first climate action plan (CAP) in introduced wind power purchases to offset the traditional energy it purchased. "Everyone felt good about that for about five years because it felt real and tangible," says Bill Braham , an architect professor at the Weitzman School.

The carbon footprint of household energy use in the United

Aug 11,  · This study uses data on ∼93 million individual homes to perform the most comprehensive study of greenhouse gases from residential energy use in the United States. We provide nationwide rankings of carbon intensity of homes in states and ZIP codes and offer correlations between affluence, floor space, and emissions. Scenarios demonstrate this sector cannot achieve the Paris Agreement
