Greenhouse gas (GHG) emissions have been identified as having a significant impact on environmental problems through changes in the climate. Although carbon dioxide is the most abundant anthropogenic greenhouse gas in the atmosphere, United States President Barack Obama’s administration has begun taking steps to decrease methane emissions.

Methane makes up only 9 percent of the nation’s greenhouse gas pollution, yet it has 20 times the potency of carbon dioxide. This allows for the gas to have a significant impact on the global climate. Moreover, methane emissions largely come from leaks in oil and natural gas production, various agricultural processes and melting permafrost.

During a 2009 United Nations climate change conference, Obama declared that the U.S. would decrease its GHG emissions 17 percent by 2020. Since then, environmentalists have argued that a substantial reduction of climate change impacts would require methane emissions to be addressed. And although a methane reduction strategy has been around for a while, the natural gas industry has been able to expand rapidly regardless of its connection to methane emissions.

The White House has stated that the Environmental Protection Agency plans to assess methane emissions and develop a strategic plan of action that is proportionate to the severity of impacts.

Reducing methane pollution may require for regulatory actions to be taken towards the oil and natural gas industry. If that is the case, there will be more of a need for U.S. to realize its renewable energy potential. This means the U.S. government would have to take meaningful steps to allow for offshore wind to develop on the Atlantic coast with solar and geothermal energy expansion in the West. It is possible, but political will and coordination on multiple levels of both the public and private sector will be necessary.

A shale-gas revolution has defined contemporary energy policy. Abundance in natural gas seemingly allowed for the heavy-emitting coal industry to be phased out for cleaner energy sources. However, analysis on methane’s impact on the global climate indicates that the effects are still significant and the GHG has to be reduced.

Therefore, with the Obama administration’s announcement of plans to cut methane emissions, it seems as though renewable energy would be the ideal avenue for energy policy.
