Air pollution, climate, and environmental change are two of the biggest environmental threats impacting human health, food security, ecosystems, and livelihoods.
At the University of York, SEI’s Air Pollution, Climate, and Environmental Change research group (AQCEC) works to quantify these threats and develop solutions.
Exposure to air pollution, both outdoors and indoors, is a critical environmental risk to human health, leading to over 5 million deaths annually. Additionally, climate change has a significant impact on food security, human health, and ecosystems, disproportionately affecting the most disadvantaged groups in society. SEI York conducts evidence-based research to support national planning and enhance capacity in climate and air pollution mitigation.
The connection between air quality and climate change stems from shared sources of air pollutants and greenhouse gas emissions, presenting a unique opportunity to develop strategies that mitigate climate change and aid in achieving the Paris Agreement while also providing local benefits for air pollution and human health.
SEI York conducts evidence-based research to support national planning and enhance capacity in climate and air pollution mitigation. By collaborating with the private sector, SEI York also tackles air pollution within value chains while prioritising social equity. We assist national planners, city officials, and private companies in assessing the impacts of air pollution and climate change at various levels across more than 30 countries. Researchers concentrate on building the capacity of national institutions and developing and applying appropriate emission mitigation assessment tools to support decision-making and enhance action to reduce both air pollution and greenhouse gas emissions.
Our work evaluates emission mitigation strategies and models future scenarios, assessing their impact on health and contributing to Sustainable Development Goals. Furthermore, the AQCEC group investigates the effects of climate change on forests, agriculture, and peatland soils, utilizing direct measurements and modeling tools to understand ecosystem responses to environmental management and climate challenges in peatland soils.
