T/CDHA 20-2024 Assessment of heat supply carbon emissions and method for assigning responsibility for carbon emissions reduction

Scope

Main technical content: Heat preparation and transmission are important links in building heating, other heat applications in buildings, and industrial production processes. The low-carbon transformation of this link is of great significance for achieving the goals of carbon peaking and carbon neutrality on schedule. With the development of technology, projects such as heat pump heating and industrial waste heat recovery and utilization have also promoted the continuous transformation of heating sources. Carbon emission accounting not only directly quantifies carbon emissions data, but also identifies potential emission reduction links and methods through the analysis of carbon emission data in various links, providing a foundation for efficient resource utilization, low-carbon energy development, in-depth adjustment of industrial structures, changes in production and living styles, and comprehensive green transformation of economic and social development. At the same time, although heat preparation and transmission are the most direct causes of carbon emissions in heating systems, the heat demand of heat users is the fundamental driving force behind these carbon emissions. To achieve dual control of the total and intensity of carbon emissions in heating systems, it is not only necessary to incentivize heat sources and heating networks to improve production efficiency and reduce the carbon emission intensity per unit of heat, but also to encourage heat users to form green lifestyles and achieve heat conservation. Therefore, it is necessary to allocate the responsibility for actual carbon emissions among heat sources, heating networks, and heat users, clarify the carbon emission responsibilities of all parties in the entire chain from heat production to heat consumption, and use this as an evaluation indicator to incentivize and constrain the carbon reduction actions of all parties. The principle of carbon emission responsibility allocation generally follows the rule
