Honoring zero-carbon commitment
China’s pledge requires immediate action of all stakeholders across multiple sectors
At the 75th United Nations General Assembly on Sept 22, President Xi Jinping stated China’s commitment to reach carbon neutrality by 2060. This reflects China’s long-term vision of collective global climate action to control the global temperature rise. It also marks China’s determination to invest in this vision. Our analysis shows that to achieve carbon neutrality by 2060, China must take immediate action, strive to follow the 1.5 C pathway set in the Paris Agreement and work toward a 75 to 85 percent reduction in greenhouse gas emissions by 2050. China will have to increase investment significantly, develop new technologies and push for stronger public awareness of climate issues.
China has an irreplaceable role to play in global climate change efforts. If it does not take proactive measures, the rest of the world must reduce emissions by over 95 percent, or even realize negative emissions by 2050 to keep temperature rise within 1.5 C, which is almost impossible. But in pursuing this climate goal, China can develop more sustainably and significantly benefit the Chinese people. Health, quality of life and well-being are strongly linked with reducing emissions and pollution, securing greater crop yields and avoiding natural disasters.
The green economy could also contribute 2 percent of projected GDP growth by 2050 and reduce
China’s fossil fuel consumption by around 80 percent, lowering its dependence on non-renewable and imported energy while boosting the competitiveness of China’s green energy exports.
The “Climate Plan for China” produced by Boston Consulting Group breaks down China’s climate commitment into a practical pathway. It translates China’s ambitious target into more than 50 specific initiatives, listing the de-carbonization contribution and incurred investment for each. Although some breakthroughs are required, the pathway is highly realistic considering China’s existing capabilities in areas such as nuclear power, solar, wind, new energy vehicles, and future potential scale-up and technology improvement.
We classified the identified emissions reduction initiatives into four categories: change of energy sources, improving operation efficiency, improving energy efficiency, and carbon capture and storage technology. Of these four, change of energy sources would have the biggest impact — accounting for around 70 percent of the total reduction in greenhouse gas emissions, mainly from clean power generation such as renewable and nuclear power in the energy sector and electrification in transport. Improving the efficiency of operations would have the second-biggest impact — accounting for around 20 percent of greenhouse gas reductions, with process innovation and sustainable agriculture initiatives comprising the largest share.
Carbon capture and storage technology would also have a sizable impact. Since it is not realistic for China to completely eradicate fossil fuels from its energy mix, the adoption of carbon capture and storage would be a must.
Decisive measures must be taken in China’s energy, industry, transport, building, and agriculture sectors. Under the 1.5 C pathway, each of these will need to reduce emissions by 60 to 105 percent, meaning close to zero emissions for some industries. This requires decisive policy support and mechanism reform, as well as effective carbon reduction levers to push sector upgrading, company transformation and public awareness.
The energy sector should encourage fair competition and technological innovation. The industry sector should promote process innovation, and help companies establish emissions monitoring and management capabilities. The transportation and building sectors should push for vehicle electrification, cooking appliances and water boilers.
China will need to invest 90 trillion yuan ($13 trillion) to 100 trillion yuan on climate measures by 2050, equivalent to about 2 percent of its expected cumulative GDP from 2020-50. The biggest investment will cover vehicle electrification and the development of clean aviation fuels. The energy sector will also need major investments to expand the use of renewable energy, nuclear and carbon capture and storage technology. Concurrently, process innovation in the industry sector, the adoption of heat pumps in the building sector and waste treatment technology in the agricultural sector will also account for a significant share.
To realize carbon neutrality by 2060, China must go beyond the
1.5 C pathway for some of the most challenging measures and further extract emissions reduction potential from anthropogenic removal. The energy sector will need to boost wider acceptance of nuclear energy by promoting further cost reductions and safety improvements. In industry sectors, it should push for full application of carbon capture and storage for in-house electricity/heat generation with fossil energy. The transportation sector should phase out internal combustion vehicles on a large scale and speed up the commercialization of hydrogen-fuel aircraft, while the agriculture sector should push the upgrading of waste incineration treatment and further grow carbon sinks.
While a major carbon emitter, China is also a model for green energy technology and land development. The sustainable development strategies and emission reductions measures China takes in the future will undoubtedly have a major impact on the world.
