The Many Benefits of Reducing Carbon Pollution from Existing Power Plants

By: Megan Ceronsky, EDF attorney, and Peter Heisler, legal fellow 

The newly-released Third National Climate Assessment has some eye-opening news about climate change.

The report confirms that if greenhouse gas emissions are not reduced it is likely that American communities will experience:

  • increased severity of dangerous smog and particulate pollution in many regions[1]
  • intensified precipitation events, hurricanes, and storm surges[2]
  • reduced precipitation and runoff in the arid West[3]
  • reduced crop yields and livestock productivity[4]
  • increases in fires, insect pests, and the prevalence of diseases transmitted by food, water, and insects[5]
  • increased risk of illness and death due to extreme heat[6]

Extreme weather imposes a high cost on our communities, our livelihoods, and our lives. The National Climatic Data Center reports that the United States experienced seven climate disasters that each caused more than a billion dollars of damage in 2013, including the devastating floods in Colorado and extreme droughts in western states.[7]

These are precisely the type of impacts projected to affect American communities with increasing frequency and severity as climate-destabilizing emissions continue to accumulate in the atmosphere.

Fossil fuel-fired power plants are far and away the largest source of greenhouse gas emissions in the United States, emitting more than two billion metric tons of carbon dioxide in 2012 — equivalent to 40 percent of U.S. carbon pollution and nearly one-third of total U.S. greenhouse gas emissions.[8] Read More »

New Methane Study Demonstrates Urgent Need for Regulatory Action

36174_Colorado River.JPGIt has happened again. Another scientific study finds methane emissions from oil and gas production are higher than previously thought, reinforcing the urgent need to reduce emissions of this powerful climate pollutant. The latest study, accepted today to be published in American Geophysical Union’s Journal of Geophysical Research – Atmospheres, measured methane concentrations in the air over Colorado’s largest oil and gas producing region on two days during early 2012 and adds to our understanding of the environmental impact of oil and gas development.

The study—led by scientists from the National Oceanic and Atmospheric Administration (NOAA) and the Cooperative Institute for Research in Environmental Sciences (CIRES) at UC-Boulder—suggests between 2.6 and 5.6 percent of gas produced in the Denver Julesburg basin escapes into the air. That’s nearly three times the amount estimated using data from the Environmental Protection Agency’s Greenhouse Gas Reporting Program. The study also found emissions of smog-forming VOC emissions to be twice as high as estimated based on state data and emissions of benzene, a known carcinogen, to be seven times higher than current state estimates.

Leading States Tackling Fugitive Emissions Problem Head-On

statesYou see something once, and it might just be an anomaly. See it twice, maybe coincidence. But when you see it a third time – that’s a pattern. A trend.

With Ohio’s move last week to control “fugitive” emissions from oil and gas operations, that’s what we’re seeing – a rapid trend from leading states to control this major source of air and climate pollution. The Ohio rules come on heels of similar actions in Wyoming and Colorado. Together, these rules signal a fast-growing recognition that fugitive emissions are a problem that has to be dealt with, and that there are cost-effective ways we can slash these emissions today.

Science and Economics Agree: The Time is Right for California to Get Serious About Methane Pollution

Larissa-Koehler-200x300Recent numbers from the Intergovernmental Panel on Climate Change (IPCC) show that methane (CH4) is about 80 times more potent than carbon dioxide (CO2) in contributing to climate change over the first 20 years after it is released. Short-lived climate pollutants, like methane, are a large factor in determining how fast our climate will change over the next few decades.

These figures are particularly relevant in California where natural gas (which is about 99.9% methane) is used throughout the economy. For example, natural gas generates much of the state’s electricity through gas-fired power plants, is extensively used for home heating and cooking, and is increasingly being deployed as an alternative fuel for the state’s cars and trucks.

Yet, while California continues to operate and further build out a natural gas backbone in its energy economy, venting and leakage of uncombusted natural gas from pipes and machines can have an environmental impact. In fact, research shows that keeping methane leakage down to a minimum level is the only way to guarantee that the use of natural gas will provide immediate climate benefits, when switching from petroleum products.

Practical Air Pollution Controls Even the Oil and Gas Industry Can’t Deny

This commentary originally appeared on our EDF Voices blog.

methane_animation_still-1_0Everyone knows that if you want your kids to grow up strong and healthy, they need to eat their vegetables. But as any parent knows, it’s easier said than done. That’s why in my house, there is a rule: you can’t have any dessert until you eat your vegetables.

Now, of course, my kids like to argue with me and my wife about exactly how many vegetables they have to eat and whether they can reach into the fridge and select a different vegetable if they don’t like the one she or I cooked that night. That’s okay. We like to encourage creative problem solving. But there’s no getting around the rule. You must eat your vegetables.

As I see it, methane pollution from the oil and gas industry is a lot like kids and vegetables. Reducing it is good for them, but we have to have a rule that requires them to do it. Read More »

Critical Decision Expected Tomorrow in Colorado on Clean Air Rule

Day 4 of the ongoing hearings on a groundbreaking proposal to reduce air and climate pollution from oil and gas operations in Colorado saw Team EDF pushing back on claims opposition groups have made to try to weaken the proposal.

Leading companies Noble, Anadarko, Encana and DCP also put on strong cases, using their own operational data to show the proposal is cost effective. They should be lauded for their leadership, as should local governments and conservation groups that brought strong analytics to the hearings.

If the proposal is adopted without being weakened, it will eliminate more than 90,000 tons of smog-forming VOCs annually (the same amount produced by all the cars and trucks in Colorado) and more than 100,000 tons of methane, a highly potent greenhouse gas.
