Population and Climate Change

The Population and Climate Change (PCC) Program aims to improve integrated assessments of the climate change issue and develop new analyses within three related projects on emissions, uncertainty, and medium-term policy strategies.

The Population and Climate Change (PCC) Program, a planned five-year project, was launched in January 2005 and concluded in December 2009. It aimed to improve integrated assessments of the climate change issue and develop new analyses within three areas:

Work in these three areas is closely related and complementary. A better understanding of demographic factors will improve future scenarios of energy use, land use, and emissions; research on uncertainty will develop new ways to account for the range of possible outcomes and responses; and medium-term policy strategies aim to keep open a range of long-term options for climate change targets while uncertainties are reduced.

The program involves disciplinary research in both the natural and social sciences, but its main aim is effective integration in support of policy-relevant analysis. It adopts a range of methodological approaches, including historical analysis, national case studies, decision analysis, and global integrated assessment modeling. Results are intended to be relevant to national and international climate change policy, to the scientific integrated assessment community, and to related disciplinary research areas in demography, economics, and climate science.

This program was primarily funded by the FWF Austrian Science Fund as part of the European Young Investigator (EURYI) Awards scheme in collaboration with the European Science Foundation.
