With the emergence of the EU CBAM and growing interest in merging climate and trade policy, it is imperative that such policies be based on transparent and verifiable data. A bipartisan group in the US Congress is committed to working with other countries to ensure that the highest standards in data transparency are followed. This session will also highlight the need for economies that are implementing CBAMs to reward countries for their actual environmental performance as opposed to basing import fees on specific policies, such as carbon pricing. Growing interest in CBAM risks undermining international cooperation in climate change if those initiatives are viewed as protectionist. Trade and climate policy must be based on transparent and verifiable data in a cooperative manner. Moreover, any import fee should be based on actual emissions performance and not specific tax or regulatory policies.
