Climate Change
Supporting emissions reduction and helping communities adapt to extreme weather events
Environmental Justice
The pursuit of environmental justice (EJ) aims to address historical inequities, marginalization and discrimination in how environmental benefits and burdens are enjoyed or suffered by certain communities.
Ecosystems
Working with communities to conserve and restore North America's terrestrial and marine ecosystems and priority species
Enforcement
Supporting enforcement and compliance with domestic environmental law and with multilateral environmental agreements

Promoting clean air, water and land through prevention, reductions, and sound management of pollutant releases, toxic chemicals and hazardous waste
Youth Engagement
Over the years, the CEC has been committed to youth engagement and the efforts supported have provided youth with opportunities to raise awareness, provide tangible, sustainable, and innovative solutions for environmental issues in their communities, and influence CEC’s strategies, projects, and initiatives.

Air Quality Improvement for Environmental Justice
Black carbon (BC) or “soot” ─a component of fine particulate matter (PM)─ is an important air contaminant that not only affects public health but also our climate.

Nature-based Solutions to Address Flood Risks in Coastal Communities Report Series
Flood-risk management is a major concern for coastal communities, particularly when considering sea-level rise caused by climate change. Nature-based solutions (NBS) have the potential to meet many flood-risk management objectives while also providing social, environmental, and economic co-benefits.
This series of guidance documents was designed to support the uptake of NBS in coastal communities across Canada, Mexico and the United States, by providing decision makers and practitioners with practical information and guidance related to NBS co-benefits, retrofitting existing infrastructure using NBS, and monitoring NBS. The documents synthesize significant previous work, incorporate insights from an interdisciplinary community of practitioners gathered through intersectoral workshops, and propose new, practical decision frameworks and processes. They also include case studies from the three countries to provide real-world context and emphasize key concepts throughout the reports.
This report series was published as part of the CEC project Nature-based Solutions to Address Flooding in Coastal Cities.
What We Do
We conduct research, provide tools and training, and provide a unique space for decision-makers and the public to engage on environmental policy issues affecting the North American region.
