Short answers, pulled from the story.
Russia accounts for roughly 4% of global greenhouse gas emissions each year. Total annual output runs between 2 billion and 3 billion tonnes of carbon dioxide equivalent, making Russia the fourth-largest national emitter in the world.
Russia is the world's largest national emitter of methane. Analysts estimated that methane worth 4 billion dollars escaped from Russian infrastructure in 2019 and 2020. The Washington Post has reported that official figures under-report the true scale of these leaks.
Russia's official goal is to reach carbon neutrality by 2060. A 2020 draft long-term strategy committed to a 33% reduction in emissions by 2030 compared to 1990 levels. Before that goal was adopted, Russia had not planned to reach net zero until as late as 2100.
In 2017, Russia's energy sector accounted for almost 80% of the country's total greenhouse gas output. The Urengoyskoye gas field was the single largest point source, releasing more than 150 million tonnes of greenhouse gas equivalents in 2021.
Russia's forests and land use absorbed 578 million tonnes of carbon dioxide equivalent in 2017, offsetting roughly a quarter of national emissions that year. Those carbon sinks face ongoing threats from illegal logging, corruption, wildfires, and peat burning.
Military emissions reporting is voluntary under international frameworks. As of 2024, Russia has made no military greenhouse gas data available for any period since before the 2022 invasion of Ukraine.
