Climate change: China’s annual emissions surpass those of all developed nations combined, report finds

But the new report highlights how difficult reducing China’s impact on the climate could be.

According to the researchers, global emissions reached 52 gigatons of CO2-equivalent in 2019, an increase of 11.4% over the past decade. And China’s share is growing fast.

While China’s emissions were less than a quarter of developed country emissions in 1990, they have more than tripled over the past three decades, the report said. In 2019, they exceeded 14 gigatons of CO2-equivalent for the first time.
