Both ‘energy security‘ and ‘ecological security‘ are fundamental notions that highlight the need for States to cooperate towards adoption of effective transnational measures to address the challenges of environmental protection and natural resource scarcity. This paper argues that policy responses to climate change should aim to redefine the notions of energy and ecological security by pursuing energy and environmental protection goals in an integrated fashion. This argument goes against the proposition that energy policies should be framed in a way that focuses on energy security, instead of environmental and climate change goals. This paper further suggests that any policy attempt to ‘decouple‘ climate change from energy policies could endanger the consistency and coherence of the legal responses to those challenges, and would ultimately contribute to further fragmentation and differentiation in global energy and climate change law.
