COP26:More than 80 countries pledge to cut methane emissions by 30 percent by 2030

Dozens of countries on Tuesday joined a United States and European Union pledge to cut emissions of methane — the most potent greenhouse gas — by 30 percent this decade, in the most significant climate commitment so far at COP26.

The initiative, which experts say could have a powerful short-term impact on global heating, followed an announcement earlier Tuesday in which more than 100 nations agreed to end deforestation by 2030.

“One of the most important things we can do between now and 2030, to keep 1.5C in reach, is reduce our methane emissions as soon as possible,” said US President Joe Biden, referring to the central goal of the 2015 Paris agreement.

He called the pledge, which has so far been signed by more than 80 nations, a “game-changing commitment” that covered countries responsible for around half of global methane emissions.

European Commission head Ursula von der Leyen said that the methane cut would “immediately slow down climate change”.

“We cannot wait until 2050. We have to cut emissions fast and methane is one of the gases we can cut the fastest,” she said.

Heads of state and government are gathered in Glasgow for a two-day high-level summit that host Britain is hoping will kick start ambitious climate action during the two-week COP26.

Organisers say the ensuing shuttle diplomacy and painstaking negotiation will be crucial for the continued viability of the 2015 Paris Agreement, and its goal to limit temperature rises to between 1.5 and 2 degrees Celsius.

While the summit’s first day passed with much rhetoric but only lukewarm climate pledges, Tuesday’s twin announcements were broadly welcomed by campaigners.

Stronger than CO2

Decades of climate pledges have been rooted in reducing carbon dioxide emissions. Yet methane (CH4) is more than 80 times more potent than CO2, and its sources, such as open pit coal mines and livestock, have received relatively little attention until now.

The United Nations last month said that global methane emissions could be slashed by 20 percent at little or no cost using existing practices or technologies.

A report from earlier this year showed that “available targeted methane measures” could see CH4 levels reduced by 45 percent by 2030.

This would shave 0.3C off projected warming, save a quarter of a million air pollution deaths and increase global crop yields by 26 million tonnes, the UN’s Environment Programme said.

“Cutting methane emissions is essential to keep global warming from breaching 1.5C,” said Helen Mountford, from the World Resources Institute.

“Strong and rapid action to cut methane emissions offers a range of benefits, from limiting near-term warming and curbing air pollution to improved food security and better public health.”

Access issues

Earlier Tuesday, countries made a multibillion-dollar pledge to end deforestation by 2030.

But the promise was met with scepticism from environmental groups, and although details were sparse, it appeared to largely resemble a similar pledge made by more than 200 countries and organisations in 2014.

The British government said that the plan to drum up around $20 billion in public and private funding had been endorsed by more than 100 leaders representing over 85 percent of Earth’s forests, including the Amazon rainforest.

The summit pact to “halt and reverse deforestation and land degradation by 2030” encompasses promises to secure the rights of indigenous peoples, and recognise “their role as forest guardians”.

While British Prime Minister Boris Johnson described the pledge as “unprecedented”, a UN climate gathering in New York in 2014 issued a similar declaration to end deforestation by 2030.

An assessment earlier this year found that seven years on from the pact, virtually no government was on course to fulfil their responsibilities.

Trees continue to be cut down on an industrial scale, not least in the Amazon under the far-right government of Brazilian President Jair Bolsonaro.

Humans have already cut down half of Earth’s forests, a practice doubly harmful for the climate when CO2-sucking trees are replaced with livestock or monoculture crops.

The laundry list for COP26 remains daunting, with pressure on leaders to commit to faster decarbonisation and provide billions to nations already dealing with the fallout of climate change.

Meanwhile, chaotic scenes continued on Tuesday around the COP26 venue, with attendees queueing around the block awaiting security checks.

By early afternoon, the UN organisers sent a text alert asking people to stay away from the venue “in order to ensure compliance with Covid-19 measures”.

Accessibility issues in the locked down city centre were highlighted as Israel’s energy minister, who uses a wheelchair, was unable to enter the venue on Monday.
