Climate Change Law: The Emergence of a New Legal Discipline

Article excerpt

[In recent times the issue of climate change has catapulted to the forefront of scientific and policy agendas. Climate change threatens to have wide-ranging impacts on ecosystems and presents enormous challenges for conventional modes of socioeconomic governance. Against this backdrop, the last few years have seen the consolidation of a body of legal rules and principles organised around the central problems of mitigating and adapting to climate change. The new climate change law spans from international to local levels of governance, and encompasses the activities of a wide range of actors including governments, businesses and non-governmental environmental groups. This article surveys the scope of the new discipline of climate change law, providing a synopsis of its primary component areas. It also elaborates the main challenges climate change law is likely to face as its development proceeds apace, such as coping with internationalisation of the greenhouse problem, ensuring that avenues for widespread participation in climate change regulation exist, and integrating governance and regulatory frameworks across political and disciplinary boundaries. How climate change law responds to this last challenge, in particular, is likely to be determinative of its effectiveness and cohesiveness as a body of law for dealing with the broad predicted impacts of global warming.]

V   Conclusion


It is only a matter of decades since lawyers first began to hail the emergence of the new field of 'environmental law'. (1) Environmental law has since developed rapidly and now encompasses a range of sub-specialities, including international environmental law, biodiversity law and water law. (2) The latest branch of the metaphorical environmental legal tree to take shape is that of 'climate change law'. It has emerged against the backdrop of intensifying scientific, economic, social and political debates over the impacts of greenhouse gas ('GHG') emissions on the world's climate system. In response, there has been an accumulation of case law, legislative development and international regulation that makes up a distinctive body of legal principles and rules identified as 'climate change law'. …
