With an energy-hungry financial system, an historic reliance on coal and huge manufacturing enterprises, China is the world’s single largest emitter, accounting for 27% of the world’s carbon dioxide and a 3rd of all greenhouse fuel emissions.
But China can also be the world’s largest producer of photo voltaic panels
and wind generators. Domestically, it’s putting in inexperienced energy at a fee the world has by no means seen. This 12 months alone, China constructed sufficient photo voltaic, wind, hydro and nuclear capability to cowl the complete electrical energy consumption of France. Next 12 months, we may even see one thing much more exceptional – the inhabitants big’s first ever drop in emissions from the facility sector.
The COP28 local weather talks started properly, buoyed by November’s Sunnyland Statement between China and the United States, the second largest emitter. At earlier local weather talks, US-China cooperation has been missing. But this time, they’re largely on the identical web page.
The assertion outlined joint assist for international tripling of renewable power by 2030, tackling methane and plastic air pollution, and a transition away from fossil fuels.
The urgency of now
China has been searching for higher coordination with the US on local weather since US President Joe Biden took workplace. Climate is an space the place these competing main powers can cooperate.
The COP28 talks in Dubai – meant to complete tomorrow – provide a window for joint motion. Next 12 months, the US might elect a special president with very totally different views on local weather. China’s well-regarded veteran particular local weather envoy, Xie Zhenhua, is about to retire.
Why renewed China-US cooperation bodes properly for local weather motion
In these talks, China – the world’s high oil importer – is searching for a compromise answer on the tense debate over fossil fuels. The world’s cartel of oil producing international locations, OPEC, has referred to as for specializing in emissions discount fairly than fossil-fuel section out within the declaration. Xie and his group are looking for a center floor to make sure a ultimate deal.
China has lengthy been criticised for its persevering with coal-fired energy plant growth. It has the world’s largest coal energy fleet, and permitted one other 106 gigawatts value of latest coal vegetation simply final 12 months – the equal of two per week. But the 5 main state-owned energy corporations are already burdened by heavy monetary losses.
Why construct soiled and clear? It’s a longstanding nationwide coverage: construct adequate baseload provide first whereas increasing renewable capacities. But at COP28, Xie mentioned one thing new:
[China will] try to interchange fossil fuels with renewable power in a gradual method.
A rustic of engineers
In developed international locations, a lot clear power work is pushed by power economists, who use incentives to alter behaviour.
China is a rustic of engineers, who see these challenges as technical fairly than financial.
In 2007, China launched a nationwide motion plan on local weather, calling for technological options to the local weather downside. Private and state-owned corporations responded strongly.
Fifteen years later, China is within the lead in each low-carbon class. Its complete put in renewable capability is staggering, accounting for a 3rd of the world’s complete, and it’s main in electrical automobile manufacturing and gross sales.
In the primary three quarters of 2023, over 53% of China’s electrical energy got here from low-carbon sources: hydro, wind, photo voltaic, bioenergy and nuclear.
How did China increase clear power so quick?
China’s big home market and large-scale deployment of wind and photo voltaic contribute vastly to plummeting renewable prices. Steadily decreasing prices means inexperienced power turns into viable for growing international locations.
In 2012, a big group from China Power Investment Corporation arrived within the excessive desert in Qinghai province and started constructing 15.7 GW value of photo voltaic throughout 345 sq. kilometres.
It was right here that China first found out how one can make intermittent energy dependable. Excess energy was despatched to a hydropower station 40km away and used to pump water uphill. At night time, the water would stream again down by means of the generators. Technologies developed right here are actually being utilized in different large-scale hybrid initiatives, reminiscent of hydro-solar, wind-solar and wind-solar-hydro initiatives.
In 2022, the federal government introduced plans to put in 500 GW value of photo voltaic, onshore and offshore wind initiatives within the Gobi Desert throughout Xinjiang, Inner Mongolia, and Gansu provinces.
These are meant to not solely supercharge China’s clear power provide, however to deal with desert growth. Solar panels stabilise the motion of sand and take up daylight, decreasing evaporation of scarce water and giving vegetation a greater likelihood at survival. This data, too, got here from the Qinghai photo voltaic farms, the place vegetation started rising within the shade.

China’s deal with know-how has given it mixed photo voltaic and salt farms, floating solar energy vegetation and power storage starting from batteries to compressed air to kinetic flywheels and hydrogen.
While the US and China cooperate at COP28, competitors shouldn’t be far-off. China already dominates many clear power applied sciences, however the US is attempting to catch up by means of the huge inexperienced spend in final 12 months’s Inflation Reduction Act.
According to the International Energy Agency, half of all emissions cuts wanted to realize net-zero by 2050 will come from applied sciences presently at demonstration or prototype section. These embody low cost inexperienced hydrogen, subsequent technology nuclear, subsequent technology photo voltaic and wind, and functioning carbon seize and storage for remaining fossil gas use.
What has China achieved at COP28?
China is backing international calls to triple renewable capability by 2030 and has agreed to deal with methane emissions, a very potent greenhouse fuel.
China is much behind power effectivity – it makes use of about 50% extra per unit of GDP than within the US, and double that of Japan. It has not invested in power effectivity because it has in different low-carbon areas.
This might change. US and China agreed in November to restart joint power effectivity work on trade, buildings, transportation, and tools, seen as tougher areas to chop emissions.
At COP28, we’ll seemingly see states conform to double the speed of power effectivity enchancment from 2% to 4% a 12 months by 2030. It stays to be seen whether or not China will be a part of them.
