But reducing methane emissions is key as it traps heat at a rate 25 times greater than carbon dioxide. Reducing human methane emissions could buy valuable time in the global effort to reduce human carbon dioxide emissions. Methane is a byproduct of oil production — and a pollutant that has environmental and health impacts. Proper handling of it should be viewed as the cost of normal business practice.
Colorado’s rules arose from recommendations of both environmentalists and producers. Capturing methane carries a certain cost. BLM leak detection and repair provisions would be offset by more gas into gas lines and more royalties paid to state coffers. It’s a net positive impact for all parties.
These rules will be increasingly important as industry continues to make new discoveries using the controversial technology that has made the natural gas boom possible, known as hydraulic fracturing. What the rules do not do is cover the multitude of existing oil and gas wells, which as of now account for the vast bulk of methane emissions. The administration has promised to develop such rules in the months ahead; without them there is no chance that Mr. Obama’s goals can be met.
Now, the EPA has followed up with a long-anticipated national rule that aims to reduce the industry’s methane emissions to 40 percent below 2012 levels by 2025 — by 510,000 tons a year, the amount of methane produced by about 10 coal-fueled power plants. The reductions can be achieved with existing technology. That will result in additional costs, but also in the industry having much more methane to sell. This is a case in which the country can have the benefits of a strong gas industry and of reduced greenhouse gas emissions. State and federal governments should make the rule work with strong monitoring and enforcement.
In fact, capturing the methane that would otherwise seep into Pennsylvania skies would be something else the industry could put on the market. Reducing methane emissions would be a winning proposition for both the industry and the commonwealth’s residents. These proposed, sensible regulations would help get us there.
Most leaks were minor, but eight were safety hazards. That may sound like relatively good news, but it isn’t. Methane is a highly potent heat-trapping pollutant, and cumulatively those leaks, apparently now fixed, will add up to long-term climate damage. The PUC report confirmed that the barn door has been shut for the moment, now that the horse has galloped full speed into the distance.
The rise in oil and gas drilling in Ohio and other states has helped trigger a welcome change in power generation, utilities switching to cleaner-burning natural gas. Yet controls on methane emissions from the industry have lagged, creating a barrier to meeting broader goals to address climate change. Compared to carbon dioxide, methane is more than 80 times more potent as a greenhouse gas.
Methane is the second-largest source of climate-warming emissions, but it has 25 times the potency of carbon dioxide, the main greenhouse gas. Toxic chemicals released during methane leaks can create smog that aggravates asthma and cancer.
In our state alone, oil and gas producers emitted almost 13,000 metric tons of methane in 2014. As drillers in Ohio increasingly rely on hydraulic fracturing to extract natural gas from shale deposits, such leaks threaten to increase. The EPA rules — the first to address methane emissions — affect only new or upgraded wells and infrastructure. They would not cover the current operations of oil and gas wells, which represent more than two-thirds of the sources of methane pollution.
