Construction activities drive half of China''''s ambient PM_(2.5)health burdenOA
Construction activities generate substantial air pollutants and greenhouse gas emissions,contributing heavily to ambient PM_(2.5)exposure and associated mortality worldwide.In China,rapid urbanization has driven a massive expansion of the construction sector,with emissions arising from building material production,onsite operations,upstream supply chains,and operational energy use in buildings.Although end-of-pipe controls have markedly lowered pollutant emissions since 2013,further reductions are increasingly costly,and air quality and climate policies remain poorly integrated.The full lifecycle health burden imposed by construction-related air pollution,its temporal evolution,and the scope for health co-benefits from decarbonization-particularly across urban and rural divides-have been incompletely characterized.Here we integrate a detailed construction emission inventory,input-output analysis,inverse atmospheric modelling,and health impact assessment to quantify these impacts in China from 2000 to 2019.We show that construction-related emissions,including upstream power and industrial sources,caused 1.10 million(95%CI:0.83-1.37 million)premature deaths in 2019,accounting for 50%(95%CI:38-62%)of national ambient PM_(2.5)-attributed mortality.Health burdens evolved through three phases:rapid increase with 130%CO_(2)growth during intense urbanization(2000-2008),decoupling via pollution controls that averted 0.36 million deaths despite rising CO_(2)(2008-2015),and synergistic declines from energy-mix optimization and technology upgrades(2015-2019).Urban mortality stems predominantly from upstream industrial emissions,whereas rural mortality is driven by residential heating;decarbonizing power and heavy industry offers the largest urban co-benefits,while rural clean-electricity heating requires concurrent power-sector greening to prevent CO_(2)penalties.These results position the construction sector as a pivotal target for integrated policies that jointly advance air quality,public health,and climate objectives.
