This course explores legal and policy developments pertaining to climate change and the regulation of greenhouse gas emissions. Approaches considered range in scale (state, regional, national, international), temporal scope (incremental measures, multi-decade emissions goals, constitutional amendments), policy orientation (voluntary initiatives, disclosures rules, subsidization, tort litigation, command-and-control regulation, cap-and-trade schemes, emissions taxes), regulatory target (industry and manufacturing, commercial and retail firms, financial and insurance companies, consumers and workers), and regulatory objective (stabilization of greenhouse gas concentrations, reduction of emissions levels or intensity, energy security, optimal balancing of costs and benefits, adaption to unavoidable impacts). Although course readings and discussion focus on existing and actual proposed legal responses to climate change, the overarching aim of the course is to anticipate how the climate change conundrum will affect our laws and our lives in the long run. No prerequisites. Self-scheduled examination or paper option.
