Global CO2 emissions remained flat in 2015, down in China and the US

According to the International Energy Agency (IEA), global CO2 emissions remained stable in 2015 at 32.1 Gt for the second year in a row, confirming the decoupling of global emissions and economic growth.

This was allowed by the rising share of renewables in power generation (renewables accounted for around 90% of new power generation in 2015, with wind power accounting for more than 50% alone). China's emissions dipped by 1.5% as coal consumption contracted for a second year in a row, highlighting the structural shift towards less energy-intensive industries and the government's efforts to reduce the use of coal in power generation: in 2015, coal accounted for less than 70% of the power mix, 10 percentage points less than in 2011, to the advantage of low-carbon sources (from 19% of the power mix in 2011 to 28% in 2015). In the United States, the large switch from coal to gas use in the power sector led to a 2% decline in emissions. However, this improvement in the two major emitters was offset by higher emissions in other Asian developing countries and in the Middle East (and in Europe, to a lesser extent). Meanwhile, the global economy grew by 3.1% in 2015, improving the global carbon intensity.
