Study: No Long-Term Climate Benefit From Shale Gas Revolution

More abundant, cheaper shale gas (dark blue) has little impact on annual growth in U.S. CO2 emissions through 2050 compared to low shale gas case (light blue). This is true for multiple energy-economy models. Deep cuts in CO2 require a rising carbon...

Carbon Capture And Storage: One Step Forward, One Step Back

A new survey finds a sharp drop in large-scale integrated projects to capture CO2 from energy systems and bury it underground. This drop from 75 projects to 65 over the past year is yet more evidence that we shouldn’t expect large-scale deployment...
