More than 20 nations including the United States called for a tripling of nuclear energy capacity by 2050 to drive down emissions on Saturday as world leaders assembled for a second day at the United Nations climate talks in Dubai.
With smoggy skies in Dubai highlighting the challenges facing the world, other pledges are expected at the COP28 conference, including stepping up the deployment of renewable energy and cutting methane emissions.
The use of nuclear power as a cleaner alternative to fossil fuels is highly controversial as environmental groups are concerned about safety and the disposal of nuclear waste.
The US, Ghana, Japan and several European countries said in a declaration that nuclear power plays a "key role" in the global goal of achieving carbon neutrality by mid-century.
"We are not making the argument to anybody that this is absolutely going to be a sweeping alternative to every other energy source," US climate envoy John Kerry said at the COP28 conference in Dubai.
"But we know because the science and the reality of facts and evidence tell us that you can't get to net zero 2050 without some nuclear," he said.
The other signatories include Britain, France, South Korea, Ukraine and the United Arab Emirates, but nuclear powers Russia and China did not sign up.
Environmental group 350.org said the Fukushima nuclear disaster in 2011 in Japan highlighted the dangers of atomic power.
"While we appreciate that the Biden administration is looking to invest in alternatives to fossil fuels, we don't have time to waste on dangerous distractions like nuclear energy," its North American director Jeff Ordower said.
Nations at the COP28 talks are also expected to adopt a goal of tripling renewable energy and doubling energy efficiency by 2030.
Methane curbs
US President Joe Biden's administration on Saturday announced it would tighten curbs on methane emissions from the oil and gas industry, a critical step toward meeting its commitments to reduce the powerful greenhouse gas.
The Environmental Protection Agency made the announcement during the COP28 climate talks in the UAE, where the host country, the US and China were set to hold talks on methane and other non-carbon dioxide gases.
Methane — which is potent but relatively short-lived — is a key target for countries wanting to slash emissions quickly and slow climate change. It is responsible for about one-third of the warming from greenhouse gases occurring today.
"The finalization of these methane standards addresses a glaring regulatory gap," Julie McNamara of the Union of Concerned Scientists said.
"For far too long, oil and gas companies have been allowed to spew methane and serious health-harming pollutants without any limits — all while shoving the towering costs of that pollution onto people and the environment."
The new standards would phase in a requirement to eliminate routine flaring of natural gas produced by oil wells and require comprehensive monitoring of methane leaks from wells and compression stations.
It would also establish standards requiring reductions in emissions from equipment such as pumps, controllers, and storage tanks.
