Sumudu A Atapattu, “Environmental justice, climate justice and constitutionalism: protecting vulnerable states and communities” in Jordi Jaria-Manzano & Serra Hunter Fellow, eds, Research Handbook on Global Climate Constitutionalism, (Cheltenham: Edward Elger, 2019) 195.
People in the Global South are both the least responsible for climate change and the most vulnerable to its nefarious effects. To account for this, this book chapter suggests expanding the framework of global environmental constitutionalism to incorporate ideas from environmental/climate justice. After describing current global environmental constitutionalism and climate justice principles, it uses South Asian jurisprudence on environmental rights to further develop this argument.
To learn more, you can read the chapter through Edward Elger. It is Chapter 12 of an extensive reference work on international environmental law.
