How Cities Undercount Greenhouse Gas Emissions
By the usual measures, wealthy "consumer cities" have largely put a check on their carbon emissions. But that doesn't account for the emissions that their consumption habits fuel in other places.
Progress on a Moonshot: Direct-Air Capture of CO2
Long considered unfeasible, direct-air capture of carbon dioxide has been achieved by a set of entrepreneurs. Scaled up, the expensive technology could slow climate change.
Clean Energy's Impact on Public Health
Because of the coal power it displaces, solar and wind energy generated in the Mid-Atlantic, and Upper Midwest has an outsized impact.
New Facility Captures Atmospheric Carbon and Stores it Underground
On April 7, the illinois Industrial Carbon Capture and Storage commenced operations, taking carbon that corn sequestered from the atmosphere and storing it safely almost a mile and a half underground in a sandstone formation.
Is Texas Ready for the Clean Energy Rule?
With the EPA's proposed Clean Energy Rule on pause in the Supreme Court, the Dallas News takes a deep dive into the state's preparation for a new era of regulation.
President Obama's Clean Power Plan Is Nation's Strongest Climate Initiative
Just over a year ago President Obama's draft Clean Power Plan was unveiled. That proposal has been finalized and the president promoted it at a press event on Monday. The final rule is both stronger and more lenient that the original proposal.
EPA Releases Carbon-Cutting Rule for Existing Power Plants
EPA Administrator Gina McCarthy announced on Monday the long-awaited proposed rule to reduce the largest source of carbon dioxide emissions. It calls for cuts of 30 percent by 2030, with the baseline year of 2005, to be finalized next year.
Are These America's Most Polluted Neighborhoods?
Regulations and a natural gas boom have helped reduce America's CO2 emissions to their lowest level since 1994. But CO2, and plenty of other toxic particles, continue to pollute our urban air. Brentin Mock looks at 5 highly polluted urban areas.
CO2 Levels Approach Troubling Milestone
The concentration of carbon dioxide in the Earth's atmosphere is fast approaching levels not seen for millions of years. At 400 parts per million (p.p.m.), the planet is fast approaching the point of no return for avoiding dangerous climate change.
The Limits of Wind Power
A new study by the Reason Foundation evaluates wind power and finds that wind power is limited in practice due to the increased need for power storage, the decrease in grid reliability, and the increased operating costs.
U.S.: Historic Drop In Carbon Dioxide Emissions
The first four months of 2012 saw 'energy-related, CO2 emissions' drop to levels not seen since 1992, according to the EIA. Graphs show an 18% decrease in carbon emissions from coal, with lesser amounts from natural gas and petroleum from a year ago
CO2 'Domes' Pose Problems for Cities
New research suggests that huge domes of carbon dioxide hover over urban areas, which is prompting some scientists and policymakers to stress the importance of cities as the frontlines of the war on greenhouse gas emissions.
