Carbon dioxide emissions flat for three years: IEA

In China, emissions fell by 1 per cent last year, as coal demand declined

Carbon dioxide emissions

Global energy-related emissions were flat for a third straight year in 2016 even as the global economy grew, according to the International Energy Agency, signalling a continuing decoupling of emissions and economic activity.

Energy-related emissions stood at 32.1 gigatonnes last year, the same as the previous two years, while the global economy grew 3.1 per cent.

This is attributed to growing renewable power generation, switches from coal to natural gas, improvements in energy efficiency, as well as structural changes in the global economy. In 2016, renewables supplied more than half the global electricity demand growth, with hydro accounting for half of that share.

According to estimates from the IEA, emissions declined in the US and China, the world's two-largest energy users and emitters, and were stable in Europe, offsetting increases in most of the rest of the world.

The biggest drop came from the US, where emissions fell 3 per cent, or 160 million tonnes, while the economy grew by 1.6 per cent. The decline was driven by a surge in shale gas supplies and more attractive renewable power that displaced coal. Emissions in the US last year were at their lowest level since 1992, a period during which the economy grew by 80 per cent.

"These three years of flat emissions in a growing global economy signal an emerging trend and that is certainly a cause for optimism, even if it is too soon to say that global emissions have definitely peaked," said Fatih Birol, executive director.

"They are also a sign that market dynamics and technological improvements matter. This is especially true in the US, where abundant shale gas supplies have become a cheap power source," she added.

The overall increase in the world's nuclear net capacity last year was the highest since 1993, with new reactors coming online in China, the US, South Korea, India, Russia and Pakistan.

Coal demand fell worldwide but the drop was particularly sharp in the US, where demand was down 11 per cent in 2016. For the first time, electricity generation from natural gas was higher than from coal last year in the US.

The said natural gas production in the US could keep growing strongly in the years to come because of appropriate policies, and large amounts of shale reserves. This could have three main consequences: it could boost domestic manufacturing, supply more competitive gas to Asia through LNG exports, and provide alternative gas supplies to Europe.

In China, emissions fell by 1 per cent last year, as coal demand declined while the economy expanded by 6.7 per cent. There were several reasons for this trend: an increasing share of renewables, nuclear and natural gas in the power sector, but also a switch from coal to gas in the industrial and buildings sector that was driven in large part by government policies combating air pollution.

Two-thirds of China's electricity demand growth, which was up 5.4 per cent, was supplied by renewables — mostly hydro and wind — as well as nuclear. Five new nuclear reactors were connected to the grid in China, increasing its nuclear generation by 25 per cent.

"In China, as well as in India, the growth in natural gas is significant, reflecting the impact of air-quality measures to fight pollution as well as energy diversification," said Birol. "The share of gas in the global energy mix is close to a quarter today but in China it is 6 per cent and in India just 5 per cent, which shows they have a large potential to grow."

In the EU, emissions were largely stable last year as gas demand rose about 8 per cent and coal demand fell 10 per cent. Renewables also played a significant, but smaller, role. The UK saw a significant coal-to-gas switching in the power sector, thanks to cheaper gas and a carbon price floor.

Market forces, technology cost reductions, and concerns about climate change and air pollution were the main forces behind this decoupling of emissions and economic growth. 

While the pause in emissions growth is positive news, it is not enough to put the world on a path to keep global temperatures from rising above 2°C. In order to take full advantage of the potential of technology improvements and market forces, consistent, transparent and predictable policies are needed worldwide.
