Researchers have detected a disease threatening cycling infrastructure investment. Although city administrators continue to invest in living streets, until cyclists becomes self-aware, the automobile will continue to dominate cities.
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 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.
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.
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.
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.
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
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.
