The road to carbon neutrality in China’s building sector

Abstract

Summary: The building sector is integral to climate change mitigation in China as well as the globe. By considering the impact of green innovation, we explore the long-term trend of carbon emissions in China’s building sector until 2060, encompassing its entire life cycle. Results show that CO2 emissions of China’s building sector will peak at 6.98–7.69 Bt in 2035 and maintain at 1.11 Bt in 2060 under the business-as-usual (BAU) scenario. The “3060 dual carbon goal” will only be achieved under the technological breakthrough (TB) scenario. These findings show that existing or relatively lax policies are insufficient to achieve the “3060” goal for the building sector. China should actively pursue green technological innovation throughout the building sector’s life cycle, with a focus on accelerating the green and low-carbon production of key products, such as steel and cement, at the building material production stage.
