Methane leaks near the COP26 venue underscore emissions challenges

Responsible and powerful greenhouse gases 40 percent Global warming over the last decade has spurted into the atmosphere from Glasgow, not far from where the COP26 Climate Summit begins.

Methane from a gas pipeline near the Ibrox football stadium, detected by researchers at the Royal Holloway University in London, leaks at a rate equivalent to 50 tonnes per year. This is the same as the emission of 500 cows.

“It was significantly larger than the other leaks we saw,” said scholar Rebecca Fisher, who found an invisible plume using a car-mounted instrument. “It really stood out.”

Methane becomes a top priority in COP26, This begins on October 31, just a mile away from the massive leak. This is because representatives are required to sign up for emission reduction pledges for the first time.

Backed by the US and EU, this commitment has already been endorsed by 33 countries that have promised to reduce emissions by 30% over the next decade, although large emitters in China, Russia and India have not yet registered. Is getting

According to U.S. climate envoy John Kelly, reducing methane emissions is the “fastest strategy” to limit global warming to 1.5 ° C levels, maintaining warming well below 2 ° C. It is set as an ideal goal under the Paris Agreement for the purpose of.

“The methane pledge may be the only and most important path to progress in Glasgow,” said Paul, a climate adviser under former US President Bill Clinton, who is currently in the Think Tank of the Progressive Policy Institute. Breadsaw said.

He added that reducing methane slows short-term temperature rise. This was important to avoid a climate “turning point” in the natural system.

Methane is about 80 times more powerful than carbon dioxide in terms of Pound for Pound’s warming factor in 20 years. However, reducing methane emissions can quickly affect temperature, as it remains in the atmosphere for only about a decade and CO2 can remain for more than a century.

Methane is the main component of natural gas, and fossil fuels account for about 35 percent of anthropogenic emissions. Waste and landfills account for about one-fifth, Agriculture About 40 percent.

Both Washington and Brussels are preparing new methane regulations — which may come soon next week in the United States. One measure being discussed in the EU is whether to regulate methane emissions associated with imported gas.

However, leaks near the COP26 venue indicate that methane emissions are often from mediocre sources. After traveling 350 km in Scotland’s largest city, Fisher detected emissions on average every 4 km. This includes four categories, large or medium.

“It’s just wasted gas,” she said. “Gas leaks are probably the easiest to fix compared to other anthropogenic methane sources.”

Over six months, Clean Air Task Force campaigner James Turitto has discovered more than 400 sources of methane at oil and gas sites in the United Kingdom and Europe. It states as follows. .. .. But my observation is that Britain needs to do more than just speak. “

One of the common causes of leaks is the gas compressor station, which regulates the pressure in the gas pipeline. Turitto visited six compressor stations operated by the National Grid and found leaks at five compressor stations, including a very large leak in Chelmsford.

National Grid, a London-listed company that operates the site, said emissions were the result of the facility resuming operations after summer maintenance activities.

The company said it plans to reduce methane emissions as part of its goal of reducing greenhouse gas emissions by 80% by 2030. To achieve this goal, we invested in better leak detectors throughout the network.

“We have a duty to ensure the safe transport of gas within the network. Managing this secure transmission results in the emission of methane emissions that are monitored and controlled in line with industry standards,” the statement said. It is stated in.

SGN, the distribution company that operates the Glasgow pipeline, is aware of the Ibrox leak and plans to fix it, but cannot immediately shut down the gas to maintain customer supply. Said that. He added that a large pipe replacement program was underway in the city.
