中国工业园区绿色低碳发展研究报告（2023）

Industry Overview - The report focuses on the green and low-carbon development of industrial parks in China, aiming to align with the essence of Chinese modernization and promote sustainable development [3] - Industrial parks are significant carriers of the real economy, with 80% of industrial enterprises concentrated in parks and 50% of national industrial output coming from these parks [7] - As of 2018, there were 2,543 national and provincial-level development zones in China, with 1,045 located in the Yangtze River Economic Belt, accounting for nearly half of the country's industrial parks [7] Policy and Practice - Green development emphasizes solving the harmony between humans and nature, as highlighted by President Xi Jinping in various speeches and policy documents [10] - Key policy documents include the "2030 Carbon Peak Action Plan" and the "Pollution Reduction and Carbon Synergy Implementation Plan," which emphasize the need for industrial parks to innovate in pollution reduction and carbon management [13] - Several pilot programs and demonstration projects have been launched, such as the National Eco-Industrial Demonstration Parks and Low-Carbon Industrial Parks, to promote green transformation in industrial parks [14][17] Achievements and Challenges - By March 2023, 225 green parks had been selected across five batches, with 111 in the eastern region, 78 in the west, and 82 in the central region [23] - The economic performance of 77 national eco-industrial demonstration parks in 2021 showed a total industrial output value of 8,009.8 billion yuan, with high-tech enterprises contributing 45% of the total output [24] - Challenges include high energy consumption, significant greenhouse gas emissions, and the need for better integration of energy, water, and waste management systems [36][38] Innovation and Vision - The report proposes a "one-core, four-core" carbon accounting framework to help industrial parks achieve carbon peak and neutrality goals, fostering new industrial competitive advantages [44] - A multi-flow, multi-process model for carbon reduction and pollution control is introduced, focusing on material, energy, and carbon flows at the enterprise, infrastructure, and park levels [45] - By 2030, 850 industrial parks in China could achieve a 41% reduction in greenhouse gas emissions and a 20% reduction in freshwater consumption through clean energy transformation [54] Sustainable Water Management - The report advocates for a comprehensive water management system that covers the entire lifecycle of water use, from extraction to wastewater treatment and reuse [55] - Smart water management platforms are encouraged to optimize water supply and usage, with a focus on non-conventional water sources like seawater desalination and rainwater harvesting [56] Data-Driven Pollution Prediction - A data-driven model for predicting volatile organic compounds (VOCs) emissions in chemical plants is proposed, leveraging machine learning to improve emission control and management [60] Comprehensive Energy Management - The report emphasizes the importance of upgrading existing energy infrastructure in industrial parks, promoting the use of clean energy, and developing smart energy management systems [62]
