Climate change impacts trade by disrupting supply chains and raising costs for businesses. Moreover, a country’s climate change policies, for example, carbon pricing or clean energy subsidies, can also affect how trade is conducted by shifting the demand for traded goods towards products and producers that contain or produce fewer emissions. As more climate policies come into effect around the globe, they have the potential to redraw international supply chains.
International trade is essential for the smooth function of the global economy, impacting products ranging from the food we eat to the cars we drive. The expansion of trade can provide new economic opportunities for countries, businesses, and individuals. But it comes at the cost of greenhouse gas emissions, not only from the transport of goods across oceans and borders, but also embodied in the goods we consume.
Growing awareness of trade’s consequences has led to a proliferation of trade policies designed to account for and mitigate the climate impacts of international trade, including through border carbon adjustments like the European Union’s Carbon Border Adjustment Mechanism (EU CBAM). Trade policies not only facilitate the implementation of climate change mitigation practices but are also increasingly in their own right becoming tools to combat climate change by ensuring access to the resources needed for a resilient net-zero economy.
Current Policy Landscape
Climate-aligned trade policies are proliferating around the world. Most notably, several countries are following the example of the EU CBAM and are implementing or considering the implementation of their own border carbon adjustments. Presently, the United Kingdom and Norway have announced they will implement similar border carbon adjustments, while Canada and Australia have held consultations to inform their decisions on whether to follow suit. In the United States, both Republicans and Democrats have introduced legislation that would establish a U.S. border carbon adjustment.
Beyond border carbon adjustments, there are numerous trade policies countries can implement, both individually and cooperatively, to align trade with climate goals. The United States-Mexico-Canada Agreement integrated an environmental chapter, requiring the parties to uphold environmental standards. Internationally, Costa Rica, Iceland, New Zealand, and Switzerland concluded the landmark Agreement on Climate Change, Trade, and Sustainability (ACCTS), the first trade agreement to include binding provisions on fossil subsidies. Trade agreements like ACCTS and even actions taken by individual countries, for example, tariff reductions on clean energy technologies or environmental goods, can accelerate the transition to net-zero.
