The Trump administration has been working to rollback rules...that would limit how much methane gas could be vented to the atmosphere at oil- and gas-drilling and processing operations. In a press release today, the Environmental Protection Agency (EPA) announced that it is proposing to relax...rules, saving the industry $484 million in avoided energy costs.
But the EPA is expected to justify its rules with analysis. That analysis (PDF) suggests that this regulatory rollback will also come with costs in the form of 308,000 short tons of methane emitted between 2019 and 2025. For context, the Aliso Canyon gas leak three years ago represented the largest accidental release of methane in US history, and over the four months that workers struggled to plug that well, 107,000 short tons of methane are estimated to have been released.
That is a serious amount of methane with serious climate consequences in the short-run. Methane is many times more potent than CO2 as a greenhouse gas, though it decomposes in the atmosphere more quickly. Carbon dioxide sticks around in the atmosphere for a longer time, but each individual molecule of CO2 has less of a warming effect than a molecule of methane.
The EPA's own analysis also says than an additional 100,000 short tons of volatile organic compounds and 3,800 short tons of hazardous air pollutants would also be emitted, compared to keeping the existing rules in place.

The EPA's current proposed action would (PDF) not only reduce the frequency with which the oil and gas industry would have to monitor for methane leaks, it would also relax requirements for companies to have a professional engineer certify that methane emissions regulations had been met. In addition, the EPA's fact sheet suggests that the agency is considering extending the time a company has to complete an initial emissions survey after a well is placed.

China's emissions are double the US emissions.

Get the world to force China to reduce emissions so the rest of the world can do it as well without being unable to compete.

China is greater than US and Europe combined.

And their emissions are going up.
