Here’s what we’re working on in Colorado:

Methane pollution – Impacts to health and environment

One in three Americans live in a county with oil and gas development. Natural gas is primarily methane, a colorless odorless greenhouse gas that can escape undetected from hundreds of thousands of different sources across the oil and natural gas supply chain—from the well pad to processing facilities, to pipelines and everywhere in between.

Every year, the industry leaks millions of tons of methane and other dangerous pollutants into the air. These emissions could be cut in half by implementing cost-effective tools and technologies. But uncontrolled, these emissions represent the waste of an important energy resource, deteriorate air quality and increase our rate of global warming.

  • Methane is responsible for about a quarter of the global warming we are already experiencing. Over the next two decades, methane will trap 80 times more heat in the atmosphere than the same amount of carbon dioxide.
  • Methane escapes with other harmful pollutants that can increase ground level ozone, also known as smog, and impact public health.
  • The oil and gas industry is the leading industrial source of methane pollution across the country, and if action isn’t taken, emissions are projected to increase 25% over the next 10 years.

“Zero tolerance” on oil and gas methane emissions brings major benefits for Colorado communities

In 2013, Colorado Governor John Hickenlooper called for “zero tolerance” of fugitive oil and gas methane emissions – a year later Colorado became the first state in the nation to directly regulate methane pollution. Each year, Colorado will reduce more than 100,000 tons of methane and nearly 90,000 tons of smog-forming volatile organic compounds — equal to the same amount produced by all cars and trucks in the state annually.

National efforts to reduce emissions are critically important. Moms Clean Air Force Colorado is working to ensure that the EPA continues work on existing source rule for regulating methane to ensure that every state is accountable for fixing leaks and curbing toxic methane emissions that can form smog, trigger asthma and even cause cancer.

“The Obama administration is on the right track with efforts to reduce oil and gas industry methane emissions, and Colorado is a shining example of how to do it right.” Denver Post Editorial

Oil and Gas Threat Map – Colorado has over 50,000 active oil and gas wells, compressors and processors in the state.  According to the Oil and Gas Threat Map, 256,000 Coloradans live within a designated threat radius with potential impacts to health.  This includes 6 counties which exceed the EPA’s cancer risk level of concern, 83 schools and 5 medical facilities (  The threat radius is defined by the EPA’s most recent National Air Toxics Assessment analysis which calculates the risk of cancer and respiratory health issues. Look up your address and see how the oil and gas industry impacts your neighborhood and community.

Ozone – Many areas are seeing rising levels of smog, or ground level ozone, which is created in the atmosphere when heat and sunlight combine with oil and gas pollution. Smog is a lung irritant that can trigger asthma attacks, interfere with normal lung development, and increase the incidence of respiratory infections.

American Lung Association’s 2016 ‘State of the Air’ Report Finds More than Half of Americans Live with Unhealthful Levels of Air Pollution

Despite continued improvement in air quality, 166 million Americans at risk from health effects of unhealthy air, according to new report from the American Lung Association

According to the American Lung Association’s 2016 State of the Air Report, Denver is the one of the top 10 Most Ozone-Polluted Cities. The city ranked 8th worst nationally for its number of high ozone level days, and, in addition to that F grade, also scored a D for high particle pollutants.

A number of other Front Range counties, including Boulder, Arapahoe, Adams, Jefferson and Douglas also received an F for ozone days.

As Colorado families deal with the health impacts of oil and gas extraction, Moms Clean Air Force is educating families, policymakers, and elected officials about air pollution and climate change, and galvanizing parents for action to reduce pollution from the oil and gas sector.

A number of other Front Range counties, including Boulder, Arapahoe, Adams, Jefferson and Douglas also received an F for ozone days.

In addition to state-specific work, Moms Clean Air Force Colorado is supporting national efforts:

Mercury: We are supporting strong limits on harmful mercury emissions from coal-fired power plants.

Climate Change: We are fighting global warming by supporting policies, namely America’s Clean Power Plan, that will reduce carbon emissions and decrease dangerous co-pollutants.

Smog: Moms Clean Air Force supports EPA’s proposal to strengthen national smog standards.

Clean Energy: We are ensuring that our energy future is renewable, clean, and healthy — for the sake of our children’s health.

Chemical Policy Reform: We are fighting to keep toxic chemicals out of the products we use every day, through joining local efforts to protect families from toxic chemicals and advocating for strong implementation of the Lautenberg Chemical Safety Act (2016).

Natural Gas Pollution: We are demanding strong protections from methane, volatile organic compounds, and other harmful air pollutants associated with fracking and natural gas development.

Colorado’s electricity generation by source, 2017:

  • Coal (54%)

  • Natural Gas (20%)

  • Wind (20%)

  • Hyrdropower (4%)

  • Other (2%)

Colorado’s vast fossil fuel resources include the Niobrara Shale, with resource estimates running as high as 2 billion barrels of oil

From 2004 to 2014, crude oil production in Colorado more than quadrupled; in the same period, marketed natural gas production rose 51%

Over 8% of Colorado children suffer from asthma

In 2017, there were 48 code orange ozone days in Jefferson County, Colorado

In 2014, Colorado’s grid-connected solar photovoltaic capacity of 430 megawatts was the ninth largest in the United States, and the state obtained nearly 10 times as much net generation from solar power as it did just 5 years earlier in 2009

Denver is the one of the top 20 Most Ozone-Polluted Cities according to the ALA’s 2018 State of the Air Report, the city ranked 14th worst nationally for its number of high ozone level days, and, in addition to that D grade, also scored a D for high particle pollutants
