What is CLEC?

The Centre for Low Emission Construction (CLEC)  works with industry partners using construction and demolition sites as 'living labs' for research and to conduct emission reduction trials that aim to measure the efficacy of mitigation and abatement techniques in a real-world working environment and to encourage adoption of 'best in class' measures across the industry.


  • Raise awareness of the air quality impacts from construction and demolition activities both to the industry itself and wider government, non-government organisations and the public.
  • Support international, national and local government in the development and delivery of policies to reduce emissions from demolition and construction projects.
  • Advise and support industry and regulatory bodies in the delivery of demolition and construction projects with minimum health and environmental impact.
  • Deliver high quality, peer reviewed research to advance the understanding of exhaust and fugitive emissions from demolition and construction projects.
  • Work with manufacturers and construction industry to develop low emission technologies to deliver cost effective, cleaner practices.
  • Quantify the health impact of exposure to emissions for the public and people working in the construction sector and provide approaches to minimise exposure.
  • Develop guidance for industry, planners and air quality professionals.
  • Train the next generation of researchers to establish low emission construction approaches.

CLEC  is part of the Environmental Research Group at the School of Public Health at Imperial College of Science, Technology and Medicine, and has over 15 years of experience working closely with policy makers, local planning authorities and partners withinthe construction sector.
