The Parties to the UNFCCC and Paris Agreement agreed to act "on the basis of equity" to protect the climate system. Equitable effort-sharing is an irreducibly normative matter, yet some influential studies have sought to create quantitative indicators of equitable effort that claim to be value-neutral (despite evident biases). Many of these studies fail to clarify the ethical principles underlying their indicators, some mislabel approaches which favour wealthy nations as 'equity approaches', and some combine contradictory indicators into composites we call 'derivative benchmarks'. This Perspective reviews influential climate effort sharing assessments and presents guidelines for developing and adjudicating policyrelevant (but not ethically neutral) equity research.
This book examines the threat that climate change poses to projects of poverty eradication, sustainable development, and biodiversity preservation. It discusses the values that support these projects and evaluates the normative bases of climate change policy. It regards climate change policy as a public problem that normative philosophy can shed light on and assumes that the development of policy should be based on values regarding what is important to respect, preserve, and protect. What sort of policy do we owe the poor of the world who are particularly vulnerable to climate change? Why should our generation take on the burden of mitigating climate change caused, in no small part, by emissions from people now dead? What value is lost when species go extinct, because of climate change? This book presents a broad and inclusive discussion of climate change policy, relevant to those with interests in public policy, development studies, environmental studies, political theory, and moral and political philosophy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
