Canada has undertaken key commitments to reduce greenhouse gas (GHG) emissions, increase adaptation and climate resilience, and realign financial flows, particularly in the country’s three successive Nationally Determined Contributions (‘NDCs’) to the global response to climate change under the 2015 Paris Agreement. Canada and the European Union (‘EU’) have also launched a new trade agreement, the Canada – EU Comprehensive Economic and Trade Agreement (‘CETA’), which recognizes that economic development, social development and environmental protection are interdependent and mutually reinforcing components of sustainable development and reaffirms both Canadian and European commitments to promoting trade that contributes to sustainable development for the welfare of present and future generations. In this brief article, several ways in which CETA might contribute to the achievement of Canada’s NDC are canvassed. The article discusses whether over time, CETA implementation will clearly commit to climate action and other sustainable development objectives; avoid constraining key laws and policies needed for climate action; intensify cooperation to limit temperature increases, increase the ability to adapt to adverse impacts of climate change, foster climate resilience and lowGHGemissions development and make finance flows consistent with sustainable development; and enhance trade in more climate and nature positive, sustainable goods and services. If so, the article suggests, CETA has the potential to foster rather than frustrate the Parties’ commitments under the 2015 Paris Agreement, and their work to advance the global Sustainable Development Goals (‘SDGs’).
