On September 20, Chinese and German experts held discussions and exchanges on the industrial energy efficiency benchmarks of the two countries, focusing on the energy efficiency benchmarks for the production of cement and glass industries. The seminar was organized by the German International Cooperation Agency (GIZ) and the China Institute of Standardization (CNIS) under the framework of the Sino-German Energy and Energy Efficiency Partnership. Experts from the two countries presented existing energy efficiency benchmarks for the cement and glass industries. Subsequently, participants from government, academia and industry discussed the similarities and differences between Chinese and German energy efficiency evaluation methods, how to better collect data, ensure data quality and deal with the complexity within the industry.
Industrial Energy Efficiency Benchmarks – An Important Tool
to Assess Energy Saving Potential Both China and Germany are committed to improving overall energy efficiency in the industrial sector, promoting industrial energy conservation and emission reduction, and helping to achieve carbon neutrality. Germany is committed to carbon neutrality by 2045 and has set a binding target to reduce final energy consumption by 26.5% by 2030 compared with 2008. China has pledged to achieve carbon neutrality by 2060, and the Comprehensive Work Plan for Energy Conservation and Emission Reduction in the 14th Five-Year Plan proposes that by 2025, China's energy consumption per unit of GDP will be reduced by 13.5% compared with 2020. Improving energy efficiency and reducing energy consumption are the core means to reduce carbon emissions at a relatively low cost, in which the improvement of energy efficiency in high energy-consuming industries plays a particularly important role. Industrial energy efficiency benchmarks are therefore the focus of this workshop. The
Industrial Energy Efficiency Benchmark is seen as an important tool for assessing energy savings potential in the future. Through the energy efficiency benchmark, the energy efficiency or carbon emission level can be benchmarked within the enterprise or industry, thus promoting and supporting the energy management of the enterprise, and helping to analyze and formulate relevant policies to improve the energy efficiency of the industry. Over the past decade, Germany has been discussing how to establish an intra-industry energy efficiency benchmark, but so far, implementation is still in its infancy.
The discussion session showed that both China and Germany face challenges in setting industry energy efficiency benchmarks , such as the collection of high-quality industry energy efficiency data. In Germany, corporate data is generally open, while in China, access to data is limited. Both sides stressed the need for trained professionals to collect data to avoid errors. When setting energy efficiency benchmarks for specific industries, the complexity of the process or product or even the altitude difference of the enterprise is still prevalent. To further address these challenges, the two sides stressed their desire to continue exchanges on energy efficiency and carbon emission benchmarks.
