There is a startling lack of global regulation of the marine ornamental trade. The only international legal framework that governs the trade of marine ornamentals is the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES). Requirements under Appendix II help prevent traded species from reaching the point where they need stricter protections, while Appendix III targets species that range countries want help controlling in international trade. Yet both of these appendices are poorly equipped to help regulate the marine aquarium trade.

The iron and steel sector contributes nearly 7% of global anthropogenic GHG emissions. As global climate commitments tighten and industrial decarbonization becomes urgent, green steel, produced using low-carbon alternatives such as green hydrogen and renewable electricity, has emerged as a potential solution. This Comment explores how national and international regulations are shaping the future of green steel, focusing on the interplay between climate policy and trade law.
