Decarbonization in Antarctic tourism: integrating the global sectoral and regional regimes
Our take
As Antarctic tourism experiences significant growth in the twenty-first century, the imperative for decarbonization becomes increasingly crucial. This article explores the complex challenge of governing emissions primarily from global aviation and shipping sectors, while leveraging the Antarctic Treaty System (ATS) for regional environmental oversight. By comparing the global sectoral regimes with the ATS, it highlights legal obligations and implementation hurdles, including overlaps with the International Maritime Organization and the International Association of Antarctica Tour Operators.
With Antarctic tourism gaining increasing popularity in the twenty-first century, decarbonization in Antarctic tourism shows a growing importance. The challenge of decarbonizing Antarctic tourism lies in governing emissions generated primarily in global aviation and shipping sectors, while relying on the Antarctic Treaty System (ATS) for regional environmental governance. This article focuses on this regulatory divide by comparing two governance layers: the global sectoral regimes for aviation and shipping, and the ATS as the regional regime. By conducting a doctrinal analysis and qualitative assessment, it examines the scope of legal obligations and implementation of both governance layers. It identifies hurdles behind the overlaps of regulations by the International Maritime Organization (IMO) and self-regulation by International Association of Antarctica Tour Operators (IAATO), and critical gaps within the ATS itself. It also argues that the global sectoral regimes display an applicability gap in governing Antarctic tourism and the ATS exhibits a jurisdictional gap. Therefore, effective governance on decarbonization of Antarctic tourism requires an integrated governance that explicitly tackles with the hurdles and bridges the gaps, fostering institutional interaction between the sectoral and Antarctic regimes and institutional development within the ATS. This underscores the urgent need for policymakers to develop coordinated strategies that align Antarctic environmental governance with global transport decarbonization ambitions.
