North–South asymmetry, unilateral environmental policy and carbon tariffs

The global community faces an urgent challenge: mitigating climate change while sustaining international trade. In this research article, Liming Hong, Wei Huang, Sajid Anwar, and Xiaofeng Lv look at the complex relationship between unilateral environmental policies, carbon tariffs, and their consequences for North-South trade dynamics and welfare.

A carbon tariff is a tax imposed on imported goods from countries with less stringent environmental regulations, especially concerning carbon emissions. The goal is to level the playing field by holding all trading partners accountable for their carbon footprint. While this may seem like a noble idea, its impact can be far-reaching and multifaceted, and the research findings reveal a delicate balance. On one hand, carbon tariffs can indeed reduce global carbon emissions. This reduction is achieved through the adoption of more advanced clean production technologies in the North, leading to increased firm profits and improved welfare. However, this positive outcome for the North comes at a cost. The global trade flows decrease, and the welfare of the South suffers. This imbalance in the distribution of benefits and drawbacks highlights the challenges in reconciling environmental goals with international trade dynamics.

As we navigate the complex terrain of climate action and international commerce, policymakers face the challenge of shaping policies that promote environmental sustainability without inadvertently harming the economies of trading partners. The research serves as a reminder that the path to a sustainable future is riddled with complexities, and finding equitable solutions requires careful consideration of all stakeholders' interests. Balancing our commitment to the environment with the realities of global trade continues to challenge us on the path to a more sustainable and interconnected world.
