This paper demonstrates the potential channels of cooperation between the EU and Turkey on green transformation. The European Green Deal (EGD) coherently brings together the existing regulatory frameworks. Moreover, EGD introduces measures such as the Carbon Border Adjustment Mechanism and extends the regulations under the Circular Economy Action Plan. These regulations will affect not only firms in the EU but also all non-EU trade partners of the EU. Adapting to the EGD is, hence, crucial for minimizing the potential costs on the Turkish exporters. In response to the EGD, Turkey prepared a European Green Deal Action Plan in July 2021 consisting of 81 targets under 9 themes. This paper argues that cooperation through the relevant decentralized EU agencies would help to revitalize the EU-Turkey relations.
