Assessment of Climate Change Mitigation Pathways (AMPERE)

AMPERE researchers used state-of-the art models to develop long-term, economically feasible strategies to lessen the global impact of climate change.

For societies to effectively cope with anthropogenic climate change, ambitious policies for long-term climate stabilization are needed. Reaching that goal requires the transition from carbon-intensive to low-carbon economies be achieved as quickly as possible. Extensive research is needed to identify good “mitigation pathways” for that transition.

The AMPERE project used state-of-the-art energy-economy and integrated assessment models to explore possible pathways to cutting greenhouse gas emissions, and to calculate the costs of following those paths. Combining the results from a sizable ensemble of models, the project focused on four areas:

  • The role of uncertainty in understanding how the climate will respond to anthropogenic forcing and how that uncertainty will affect global energy supplies;
  • The role of technology and innovation in the energy sector;
  • The role of political limits to policy such as limited regional participation in climate change regimes; and
  • The implications for Europe of policies to “decarbonize” the energy sector.

IIASA Research

Using IIASA's MESSAGE and GAINS models, researchers analyzed the effects of different low-carbon technologies on mitigation pathways. Researchers  also looked at the effects of climate feedbacks such as a warming-induced increase in methane released from permafrost, which in turn causes more warming. They also used MESSAGE to conduct a comparative analysis of the economic costs of the various mitigation scenarios developed as part of the project.
