Good air quality is vital to human health, agriculture and functioning ecosystems, and air pollution can have a big impact on the climate. SEI carries out pioneering research on the impacts of, and solutions to, air pollution, from household up to global scale.
More than 65% of the world's population are projected to live in cities by 2050, with major implications resource use, energy, water and sanitation, and health and well-being. At the same time urbanization can bring benefits, especially efficiency gains. SEI examines these challenges in the round to advance sustainable urbanization.
Media coverage / SEI and UNEP have been working with sports federations across Africa to improve air quality monitoring by installing sensors.
How can we meet the nutritional needs and expectations of a growing world population? And how do we do it without compromising long-term sustainability? SEI research explores the transition to sustainable food and agricultural systems.
Event on 27 April – 02 May in Vienna / SEI researchers are seeking abstracts from practitioners and scholars for their session at the European Geosciences Union (EGU) General Assembly 2025 in Vienna.
Around 2.4 billion people use biomass fuels – wood, charcoal and animal dung – for their domestic energy needs. These are typically burned in inefficient stoves or on open fires, with serious consequences for health and the environment. SEI identifies and designs actions to help households transition to cleaner technologies and energy sources.
Perspective / On World Ventilate Day 2024, SEI researcher Luke Gooding emphasizes the importance of ventilation during retrofitting to meet net-zero goals.
Pollution from human activity threatens both human health and vital ecosystems. SEI looks at issues of air pollution from household up to global levels, for example how pollution links to climate mitigation, urbanization and public health, and the potential role of citizen science in pollution monitoring.
Media coverage / SEI and UNEP have been working with sports federations across Africa to improve air quality monitoring by installing sensors.
We assess the impacts of and work to reduce the levels of short-lived climate pollutants – such as soot, methane and ozone – in the atmosphere. These agents affect human health and contribute to global warming.
Feature / The UN Global Nitrous Oxide Assessment, co-authored by SEI’s Kevin Hicks, urges bold action to cut N₂O emissions.
SEI identifies policies and solutions that can support shifts toward clean and efficient transportation systems – which are vital to protect the climate and human health, and for sustainable cities.
Past event / At the 2024 World Urban Forum, SEI York and partners will strengthen stakeholders capacity on inclusive and climate-resilient urban transportation in Africa.
