14 CHINA INVESTMENT Issue3 、 4, February 2022 15 中国投资 2022年2月第3 、 4期 By Nicholas Howarth and Clara Camarasa ，Energy Efficicency Policy Analysts, Energy Efficiency Division, International Energy Agency Early investment in energy efficiency in China is key for carbon neutrality and economic development China doubled its rate of energy intensity improvement over the last decade, helping lift global progress Over the last decade, the average rate of energy intensity improvement in China doubled to around 3.5 each year from the 1.7 seen between 2000 and 2010. This result was delivered despite the significant slowdown of energy intensity improvements which has been observed globally and in China since 2015. The notable improvement in energy intensity during the first half of the last decade reflects the priority placed on meeting energy intensity targets in China’s Five Year Plans FYP and the significant boost to efficiency spending following the 2008 financial crisis and the implementation of several mandatory energy efficiency policies. Well targeted government support has also helped build the world’s largest energy service market with Chinese Energy Service Company ESCO investment making up around 60 of the global market. Total annual investment in energy efficiency in China is now estimated to be around USD 70 billion, up by 15 compared with pre-crisis levels and accounting for nearly one-quarter of the global spending. Improving energy intensity will play a key role in helping achieve China’s targets to have CO2 emissions peak before 2030 and reach carbon neutrality before 2060. At a global level, a doubling of energy intensity improvement will be needed over the next decade to reach net zero emissions by mid- century In its recently released Energy Efficiency Market Report, the International Energy Agency IEA found that the global rate of energy intensity improvement in 2021 is expected to recover to 1.9 after its worst year in a decade.

While the recent economic recovery brings the rate of improvement back to its ten year average, it is still only half of what is needed to put the world on track to reach net zero emissions by mid-century. The report also examined over 40 energy efficiency actions based on the IEA’s Net Zero by 2050 Roadmap, to help countries achieve efficiency goals to limit the global temperature rise to 1.5 °C. This roadmap recognises that different countries will be moving at different speeds and will also choose different options based on national resources and circumstances. For energy effcieincy such actions include scaling up use of mature technologies in buildings, appliances, transport and industry. Many of these actions are already being pursued as part of China’s industrial enterprises programmes. For example, encouraging best available technology for electric motors is key as they account for approximately 65 of total electricity consumption in China. Expanding the scope of efficiency programmes to include more manufacturing sectors – such as vehicles, machinery, food, timber and textiles – also offers large scope for efficiency gains. This is because more than 90 of heat demand in light industry is low and medium temperature, which can be more easily switched from fossil fuels to more efficient electric processes, such as heat pumps. This compares with heavy industry such as steel and cement where electrification potential is more limited. In China, the 14th FYP 2021-2025 includes a target to reduce carbon intensity by 18 by 2025 and a target for reducing energy intensity by 13.5. This compares with a 15 energy intensity reduction target over the 2016-2020 period. As in many countries, slowing economic growth due to the pandemic and a shift towards more energy intensive sectors of the economy as restrictions reduce activity in sectors such as hospitality and tourism has slowed energy intensity improvements in China. The challenge for policy makers is to develop and implement policies that can both support economic growth and enhance environmental protection. Energy efficiency- related spending offers this solution, making up around two-thirds of all clean energy and sustainable recovery spending, according to the IEA Sustainable Recovery Tracker. While China’s past results have been impressive, the recent slowdown in intensity improvements, combined with goals to achieve carbon neutrality, makes lifting efficiency efforts more important than ever. Doubling the efficiency of new appliances by 2030 is possible and the focus of the world’s largest ever international energy efficiency initiative Efficiency standards and labels have been shown to reduce electricity demand by the equivalent of the total electricity generation of wind and solar energy in the nine countries and regions for which the data are available. Such standards have been in place longer in the European Union and United States, but China is catching up. The implementation of standards in China is already helping avoid around 5 of total national electricity consumption each year, reducing annual CO2 emissions by 80 million tonnes. These savings will grow, as old stock is replaced by more efficient equipment though standards need to be continually ratcheted up to optimise savings. Along with 21 other governments, China is a member of the Super-efficient Appliance Deployment SEAD Initiative – a collaboration with the IEA and other partners to accelerate and strengthen the design and implementation of appliance energy efficiency policies. Such international collaboration enables governments to design standards based on global best practice. For example, in November 2021, the IEA and the COP26 Presidency launched the COP26 Product Efficiency Call to Action to double the efficiency of key appliances by 2030 – particularly for lighting, industrial electric motor systems, air conditioning and refrigeration. The initiative aims to help countries raise ambition faster and at a lower cost. Electric mobility start-ups raise more money than other sectors, with strongest activity in China and the United States Venture capital VC activity can help track progress of clean energy innovation. While governments typically account for most early-stage research and development R whilst simultaneously taking advantage of the multiple benefits associated with energy efficiency such as increased industrial productivity, local job creation, and health benefits from reduced local air pollution.
