According to the greenhouse gas reduction agreement reached between China and the United States not long ago, China promised to stop increasing carbon dioxide emissions by 2030, which is equivalent to committing to peak emissions. Some people think that this will bring enormous challenges and pressure to China's employment and local finance. However, after research, I believe that setting peak carbon emissions will not put extra pressure on the economy, and this goal may be achieved ahead of 2030.
The peak of carbon dioxide emissions needs to be based on the peak coal consumption, and then the reduction of coal emissions to offset the carbon emissions growth of oil and gas. Now, smog has become a problem for the whole country, and the key to smog management is coal replacement, which is consistent with the goal of reducing carbon dioxide emissions.
Studies have shown that even under normal smog control intensity, China's coal consumption peak will appear in 2023, and the corresponding carbon dioxide emissions will peak in 2028. Although many factors affect the timing of carbon dioxide peaks, including the progress of energy price reforms, the implementation of carbon taxes and carbon trading, the impact of smog treatment on carbon dioxide peaks is the most direct. Through stricter smog control measures, China's coal consumption and carbon dioxide peak time may be advanced to 2020 and 2024.
So, what are the specific difficulties and solutions to achieve peak coal consumption? In general, the peak consumption of coal depends on two factors: First, of course, it needs sufficient clean energy to replace coal, and alternative energy must be able to meet the energy needs of economic development. The second is the cost issue. Whether short-term natural gas replaces coal, or medium- and long-term clean energy replaces coal, it will face an increase in energy costs, because other alternative energy sources for coal are more expensive than coal.
This time, while determining the peak point of carbon emissions, the government also promised that non-fossil energy will account for more than 20% by 2030, compared with 9.8% in 2013. To meet this commitment, nuclear power development is critical, and it can meet both the volume and cost issues. In 2013, China's nuclear power installed capacity was 14.61 million kilowatts, accounting for only 1.2% of the total installed capacity, and the power generation was less than 2%, while the US nuclear power generation accounted for 19%, which is more obvious than the gap between nuclear powers such as France. At present, hydropower, wind power, solar power, biomass and geothermal energy account for a small proportion of China's primary energy, and it is difficult to improve it in the future. Therefore, the development of nuclear power is an unavoidable choice for China.
The early emergence of smog management and peak carbon dioxide emissions requires a combination of long and short policy combinations. In the short-term, through the establishment of environmental standards and constraints, and energy price reforms reflect the scarcity of environmental and resource costs, the peak of coal will appear as early as possible, and the medium and long-term needs to solve the high energy cost caused by coal substitution through technological advancement and business model innovation.
If smog governance is linked to carbon dioxide peaks, when China pays enough for smog governance, the peak of carbon dioxide emissions in 2030 will be an inevitable result and will not put additional pressure on the economy.
