北京市某大型水务集团碳中和规划与实践
- Title:
- Carbon Neutrality Plan and Practice of a Large Water Group in Beijing
- Keywords:
- sewage treatment; carbon neutrality; plan; practice
- 摘要:
- 为响应我国实现碳中和目标，2021年北京市某大型水务集团（以下简称“集团”）率先在全国水务行业发布《碳中和规划》和《碳中和实施方案》，旨在引领我国水务行业绿色转型，推动水务行业更高质量发展。详细介绍了碳中和规划核算边界及方法、规划的总体要求和实施举措。围绕“管理创新，推进绿色低碳运营” “技术创新，实现清洁能源替代” “生态服务创新，实现生物固碳”三个方面，详细阐述了碳减排措施及应用效果。预计到2025年，集团碳排放强度较2020年下降20%，其中存量减碳和绿能替代贡献比例各为10%。到2035年，碳排放强度较2020年下降40%，其中存量减碳和绿能替代贡献比例各为20%。到2050年，碳排放强度较2020年下降80%以上，其中存量减碳20%，集团自身绿能替代20%，根据北京市绿电消纳安排外购绿电40%；剩余20%通过购买碳汇等市场化机制完成碳中和，基本实现近零碳排放。
- Abstract:
- In order to achieve China’s carbon neutrality goal, a large water group in Beijing took the lead in releasing the Carbon Neutrality Plan and Carbon Neutrality Implementation Plan in the national water industry in 2021. The objective is to lead the green transformation of China’s water industry and promote its higher quality development. This paper introduced the accounting boundary and methodology of the carbon neutral plan, outlining the detailed requirements of the plan and implementation measures. The content had elaborated on carbon emission reduction measures and their application effects, focusing on three aspects: management innovation promoting green and low-carbon operation, technological innovation realizing clean energy substitution, and ecological service innovation realizing biological carbon fixation. By 2025, the carbon emission intensity would be reduced by 20% compared to 2020, with stock carbon reduction and green energy substitution contributing 10% respectively. By 2035, the carbon emissions intensity would be reduced by 40% compared to 2020, with stock carbon reduction and green energy substitution contributing 20% respectively. By 2050, the carbon emission intensity would be reduced by more than 80% compared to 2020, comprising 20% stock carbon reduction, 20% own green energy substitution, and 40% outsourcing of green electricity as per Beijing’s green electricity consumption arrangement. The remaining 20% carbon reduction will be offset through market-oriented mechanisms such as acquiring carbon sinks, allowing the group to achieve near?zero carbon emissions.
