Topics
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

Pollutants
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.
Indigenous Affairs
The Commission for Environmental Cooperation (CEC) recognizes the essential role that Indigenous Peoples and local communities play in environmental stewardship across Turtle Island, Madre Tierra, also known as North America.
Private Sector Engagement
The private sector plays a critical role in driving economic prosperity, innovation and sustainable development.
Featured Project

Featured Publication
Milestone Study on Plastics Waste Management in the US and Canada — Full Report
This study examines the plastic waste value chain in Canada and the United States for thermoplastic resins or commodities—the materials most involved in the manufacture, distribution and commercialization of plastic products in the country. The publication includes an overview of related infrastructure, operational management and associated markets and documents the current state of recovery and recycling practices. It also outlines existing public policies and regulations within a circular economy (CE) framework.
The publication describes good practices and provides recommendations to strengthen Canada’s and the United States’ waste management system. In addition, best practices in waste management that can be implemented based on the findings of this study are identified, with the goal of providing information for decision-makers.
This publication is part of the project: Transforming Recycling and Solid Waste Management in North America. The Commission for Environmental Cooperation (CEC) commissioned a series of milestone studies on the recycling and management of paper and cardboard, plastics and bioplastics waste for Canada and the United States, and for Mexico. A pilot study on composting poly-coated fiber food packaging for Canada and the United States complements this series. Together, these publications aim to accelerate the adoption of CE practices and promote strategies for the sustainable management of these materials, generating economic and environmental benefits across the region.
The complete report is available in English only, but you can consult the executive summary in English, Spanish, and French.
