摘要：It is widely accepted that climate change raises equity considerations, and this has been
addressed in various explicit and implicit ways in scenario-based climate and climate-policy
research. In this paper I look in particular at the IPCC's well-known 'Special Report on
Emissions Scenarios', in which equity is primarily quantified as the distribution of income
between countries, and highlight the need for more explicit treatment of equity both within
and across national borders. I apply an existing method for modeling subnational income
distributions and show that this affects the results of welfare calculations of the
type used in economic analyses of climate policy. Additionally, I suggest ways in
which this kind of equity analysis could be applied to questions that address
broader considerations of climate policy and development, such as burden sharing in
the allocation of obligations, and conclude with remarks that frame the scenario
development process in the context of what I call 'the contested storyline of the present'.
