US Senators Launch Bipartisan Effort to Address Short-Lived Climate Pollutants

Senators Susan Collins of Maine, a Republican, and Chris Murphy of Connecticut, a Democrat, have jointly introduced The Super Pollutants Act of 2014.

2 July 2014 – In welcome news, two US Senators have launched a proposal to address short-lived climate pollutants in the United States.

Senators Chris Murphy of Connecticut, a Democrat, and Susan Collins of Maine, a Republican, have jointly introduced The Super Pollutants Act of 2014, which targets black carbon, methane and hydrofluorocarbons as dangerous climate pollutants. The Act builds on a similar effort from Representative Scott Peters of California, who introduced a bill on short-lived climate pollutants in the House of Representatives in May of 2013.

“I’m proud to be leading the bipartisan effort to tackle short-lived climate pollutants here in the Senate, building on the incredibly important work that the CCAC has led at the international level,” said Senator Murphy. “In a little over two years, the CCAC has marshalled 38 nations and countless partner organizations to address the environmental and public health threats posed by methane and black carbon, and I’m excited to be able to champion those initiatives here amongst my colleagues.”

The US government has been an active partner in the CCAC, leading or co-leading initiatives on reducing short-lived climate pollutants in oil and gas production, heavy duty diesel vehicles, municipal solid waste, HFCs and agriculture.

“It is always welcome news when a government realizes that short-lived climate pollutants need to be a major part of climate and environmental strategy,” said Helena Molin Valdes, Head of the CCAC Secretariat. “We are very pleased that Senators Murphy and Collins have shown such leadership, and we look forward to working with the US and other governments as we grow in our efforts to reduce these dangerous pollutants.”

The Climate and Clean Air Coalition to Reduce Short Lived Climate Pollutants is a partnership of governments, intergovernmental organizations, the private sector, the environmental community, and other members of civil society. The Coalition is government-led but is highly cooperative and voluntary. Short-lived climate pollutants are agents that have a relatively short lifetime in the atmosphere—a few days to a few decades—but also a warming influence on climate as well as, in many cases, detrimental impacts on human health, agriculture and ecosystems.
