Just Two Actions May Stop the Planet’s Runaway Warming (Op-Ed)
(More)

Since the Industrial Revolution, methane in the atmosphere has increased by a whopping 150 percent. While in the same period, CO2 levels have gone up 40 percent. Around one quarter of today’s human-caused warming is attributable to emissions of methane, while human-caused CO2 emissions account for around half.

The administration of U.S. President Barack Obama is currently undertaking efforts to reduce emissions of some of the most damaging greenhouse gas emissions responsible for climate change: methane pollution from oil and gas operations and carbon dioxide from coal-fired power plants. This strategy has prompted questions about which climate pollutant should take priority. But the discussion of whether to cut methane emissions first and carbon dioxide later — or vice versa — is not helpful or necessary. We need a two-pronged strategy to stay safe.

Understanding the urgent need to reduce all types of climate pollution, the Obama administration is expected to move forward with rules to mitigate both methane and carbon dioxide in the next few months. This summer the U.S. Environmental Protection Agency (EPA) is expected to propose the first ever direct regulation of methane emissions from new and modified sources in the oil and gas industry, and finalize its Clean Power Plan to reduce carbon dioxide from coal-fired power plants.
