摘要

Cities and urban agglomerations house more than 50% of the global population and contribute more than 70% of global greenhouse gas (GHG) emissions. By 2050, two out of three people will live in urban areas, adding another 2.5 billion people to the global pool of urban dwellers (State of Green Weekly, 28 June 2023). Digital city climate planning is a newly emerging field and rapidly developing discipline. Urban GHG emissions can be effectively reduced through low-carbon district heating with digital opportunity. Generating electricity using natural gas produces up to 50 per cent fewer emissions than conventional coal-fired generation (Queensland Government in Climate Smart 2050, Queensland climate change strategy 2007: a low-carbon future, p viii, 2007). The Korea’s digitalized district heating system from LNG and other sources to provide low-cost heating is one of innovative projects backed by climate policy of the government. The smart remote metering projects were launched as the Green New Deal project for apartments by the Korea Smart Grid Project Team, Ministry of Industry, Trade and Resources of Korea in order to increase energy efficiency. This chapter aims to demonstrate how digital technology can support climate action by using digitalized consumption-based GHG accounting system for district heating. It focuses on AI revolution in the consumption-based GHG accounting system. The chapter presents research findings on the evolution and operation of digitalized consumption-based GHG accounting system for LNG-based district heating in Korea. It deals with heat supply, demand, consumption and value chain for district heating with help from data scientists for heat metering. It is shown that there is a need to use remote digital meters for consumption-based GHG accounting of district heating over the lifetime of projects from utilities to buildings to tenants in order to measure emissions at the household level. LNG is one of green energy options Korea is exploring for district heating. Finally, some suggestions are made for future-oriented research in the area of digitalized consumption-based accounting that will facilitate its application to climate policy.
