White House announces new methane regulations, kicking off global pledge
The EPA regulations target, in particular, methane leaks and
instances when methane gas is purposefully vented, or flared, during the
production process.
The Biden administration on Tuesday announced plans to
introduce some of the nation's strongest regulations against methane emissions
from oil and gas drilling, part of a broader push to tackle climate change that
White House officials are unveiling at the United Nations Climate Change
Conference.
The new rules, proposed by the Environmental Protection
Agency, aim to curb methane emissions for new and existing oil and gas
infrastructure, thereby reducing a significant source of pollution from fossil
fuel companies. The regulations target methane leaks and instances when methane
gas is purposefully vented, or flared, during the production process.
Methane is a potent greenhouse gas that is released into the
atmosphere when coal, oil and natural gas are mined and transported, but
microbes also emit methane in low-oxygen environments. Methane emissions have
been responsible for roughly 30 percent of global warming since pre-industrial
times, according to the U.N. Environment Programme.
An estimated 75 percent of the country's methane emissions
will be covered by the new EPA rules, according to senior administration
officials.
In addition to the EPA regulations, senior administration
officials said more than 80 countries are set to join the U.S. and the European
Union in pledging to collectively reduce the world's methane emissions by 30
percent by the end of the decade.
The announcement is a key development in the global fight
against climate change and one that will likely help Biden signal to allies
that the United States is taking serious action on climate, even as divisions within
his own party are threatening other aspects of the president’s climate agenda.
Methane accounts for a much smaller percentage of global
greenhouse gas emissions compared to carbon dioxide, but methane's molecular
structure makes it more readily able to absorb thermal radiation, meaning it
can drive significant short-term warming.
Research published last year in the journal Earth System
Science Data found that human activities contribute about 60 percent of global
methane emissions. Agriculture makes up roughly two-thirds of that figure, and
fossil fuel production and use account for most of the rest, the study found.
The EPA rules will be stricter than regulations on methane
emissions that were set in 2016 during the Obama administration. Those rules
were relaxed by former President Donald Trump, but methane standards were
reinstated shortly after Biden took office.
Sarah Smith, a program director at the Clean Air Task Force,
a nonprofit advocacy group, hailed the U.S. and EU leaders' involvement in
launching the so-called Global Methane Pledge.
"For too long this potent super pollutant has fallen
off the agenda at major climate summits while its emissions have risen to
all-time highs, pushing our planet closer to potentially irreversible tipping
points," Smith said in a statement. "By launching the Global Methane
Pledge on the world stage, they've made sure that methane will be front and center
— where it belongs."
