New International Energy Agency analysis sees cost-effective pathways to steeply cut oil-and-gas sector emissions of the potent greenhouse gas methane far more than what's projected under existing policies.

Driving the news: The report looks at methane from the fossil fuel sector and how to achieve a 75% cut by 2030 that's consistent with IEA's wider roadmap for net-zero global greenhouse gas emissions by 2050.

The big picture: That would require efforts far beyond current initiatives, but it's feasible, especially for oil-and-gas emissions, IEA said.

  • "[I]t is possible to avoid more than 70% of current emissions with existing technology, and where around 45% could be avoided at no net cost," it finds.

Why it matters: "Methane has contributed to around 30% of the global rise in temperatures to date," IEA notes.

The Biden administration is expanding efforts to speed clean electricity expansion with its existing powers, but faces big obstacles to meeting its climate goals without far more help from Congress.

Why it matters: President Biden has set a goal of reaching 100% carbon-free power by 2035 and cutting economy-wide greenhouse gas emissions — that is, power, transport, industry, etc. — in half by 2030.

World ocean temperatures in 2021 were the hottest ever recorded by humans, according to a new peer-reviewed study.

Driving the news: The research ties the warming trend conclusively to human emissions of greenhouse gases from the burning of fossil fuels, such as coal and natural gas.
