Compared to other ethical approaches to climate change, a human rights
approach has several advantages: it draws on a widely accepted, coherent
and well-developed set of legal norms, it places the human beings most
affected by climate change at the centre of its analysis, and it has
strong connections to mechanisms of implementation and enforcement.
Human rights already provide a sturdy framework for addressing climate
change at the micro level of specific projects and national adaptation policies, but face greater challenges at the macro
level of global mitigation of greenhouse gas emissions. Nevertheless,
human rights law contains elements that should allow it to address
climate change as a global challenge to human rights.
