WASHINGTON -- The Environmental Protection Agency says greenhouse gas emissions in the United States showed a 1.6% decline from 2010 to 2011. The decrease continued an overall decline in U.S. greenhouse gas emissions, down 6.9% since 2005. The EPA said the drop from 2010 to 2011 is driven mostly by power plants switching from coal to natural gas, which emits less carbon dioxide when burned. Additionally, a mild winter in the south Atlantic region of the U.S., where much of the heating is electric, resulted in lower electricity demand.

SACRAMENTO - When Gov. Jerry Brown called on his fellow governors at a conference in Washington last week to embrace a California-style pursuit of cleaner air, he was doing more than reinforcing the state's image as an environmental trailblazer. He was trying to protect its economy. Brown needs other states and the federal government to adopt key elements of California's environmental agenda, such as reaping more energy from renewable sources and capping greenhouse gas emissions, if those programs are to be successful here.

Activist investors have succeeded for the first time in placing a shareholder resolution on the risks of greenhouse-gas emissions up for a vote at a major bank, a step toward making climate change an important consideration for corporations. The resolution, which follows years of protests over banks financing certain coal operations, is to be included in proxy material being sent to shareholders of PNC Financial Services Group of Pittsburgh before the bank's April 23 annual meeting.

WASHINGTON - After President Obama finished his inaugural speech Monday, Rep. Henry A. Waxman (D-Beverly Hills) thanked him for mentioning climate change, a topic environmentalists said Obama had avoided during much of his first term. "I did more than mention climate change," the president told Waxman. In discussing the urgency of climate change before a national audience, the president elevated the issue into the top tier of second-term priorities that include fiscal reform, gun control and immigration reform.

To a casual observer, it looks like someone barnstorming several hundred feet above sparsely populated Central California terrain in a small plane. But it's UC Davis atmospheric researchers surveying Pacific Gas & Electric Co.'s 600 miles of natural gas pipelines between Sonoma and Fresno in a single-engine Mooney TLS packed with scientific instruments designed to sniff out leaks of methane, a potent source of global warming. Their mission: Find gas leaks several miles downwind from the source cheap and fast, then dispatch ground crews to fix the problem and stop more pollution from spewing into the air. The $295,000 experimental project is funded by the industry organization Pipeline Research Council International, with principal backing from PG&E.

Environmental researchers have detected excess greenhouse gas levels near the site of Australia's biggest coal seam gas field, prompting calls for halting expansion of hydraulic fracturing until scientists can determine whether it might be contributing to climate change. The reported findings of methane, carbon dioxide and other compounds at more than three times normal background levels have stirred new controversy in eastern Australia over the pros and cons of boosting natural gas output by "fracking," a process that blasts sand, water and chemicals into deep underground wells.

SACRAMENTO -- California environmental officials went ahead with a planned, first-ever auction of greenhouse gas pollution credits despite a last-minute lawsuit filed by the state Chamber of Commerce. On Wednesday, the Air Resources Board manned computer terminals to take bids from some major industrial facilities such as cement plants, steel mills, refineries and food processors. Many companies that emit carbon dioxide, methane and other gases that contribute to global warming were expected to participate in the three-hour sale of so-called cap-and-trade credits.

Climate scientists are creating a three-dimensional carbon dioxide emissions map of the city of Los Angeles that will detail greenhouse gas emissions for individual buildings, road segments and power generators over time. The mapping project is part of an effort by Arizona State University researchers to eventually map all major cities in the United States to help guide climate policymakers. In a report published Tuesday in the journal Environmental Science & Technology, atmospheric scientist Kevin Gurney and colleagues described how they recently completed a similar map for the city of Indianapolis.
