A new study published in Nature Energy highlights the unequal residential heating burden caused by the phase-out of coal-fired combined heat and power (CHP) plants in pursuit of climate goals, particularly in northern urban China.

The early retirement of these power plants, while essential for reducing carbon emissions, has raised significant challenges for heating systems in regions heavily reliant on CHP. Researchers led by Zhaohua Wang and his team projected the spatiotemporal evolution of CHP heating capacity, urban heating demand, and residential heating costs under different climate goal scenarios.

The study revealed that the loss of heating capacity resulting from the retirement of coal-fired power plants is comparable to the heat that could be generated by installing solar photovoltaic heating on over 17.8% of the rooftops in the European Union. Furthermore, the transition from CHP heating to cleaner alternatives is likely to disproportionately increase residential heating costs, particularly in economically disadvantaged areas. This alarming finding highlights the potential social risks and injustices associated with the implementation of coal retirement strategies without considering the equitable distribution of heating costs.

To address this pressing issue and facilitate a smooth transition towards clean and affordable space heating, the researchers emphasize the importance of formulating targeted policies. The policies should consider the specific needs of economically vulnerable communities, ensuring that the burden of higher heating costs does not fall disproportionately on their shoulders. By combining climate goals with measures aimed at social equity, policymakers can strike a balance between environmental sustainability and the well-being of the population, enabling a successful shift towards cleaner heating systems in northern urban China.
