• What we do: PIK addresses crucial scientific questions in the fields of global change, climate impact and sustainable development.

• Who we are: Researchers from the natural and social sciences work together to generate interdisciplinary insights and to provide sound information for decision making to civil society, politics and the economy.

• How we work: The main methodologies are system and scenario analysis, modelling, computer simulation, and data integration.

• Formation: 1992 • Staff: 340 members of staff,

of which 220 scientists, and 130 guests

• Resources: 15,2 M€ institutional funding (BMBF, MWFK) and approx. 12,3 M€ from external sources

RECENT DEVELOPMENTS

New Building New Super-Computer

• 212 trillion calculations per second – so called Teraflops;

• among the 400 fastest world-wide; • waste heat used to heat new

building. • 191 offices • Innovative materials and overall

energy efficiency will be assessed in a research project by the Technical University Dresden.

RD3: METHODS, MODELS & TOOLS

• global scale fully integrated

• global damage model • regional models • numerical models of

(multiple) policy instruments

• analytic models for the design of policy instruments

Considerable efforts to develop a standard methodological tool box with conceptual models, e.g. • inter- and

intragenerational justice, environmental federalism.

Models explore the full spectrum of options for climate change:

Political and economic analysis of climate policy

• Public finance and climate policy: Closing the carbon price gap • Ex-post analysis of existing climate policies, e.g. EU ETS • Distributional effects

SCIENCE POLICY INTERFACE

Map makers & navigators, facts & values

• Our research guides decision makers, thus we carefully distinguish framing, transformation pathways („maps“) and tools for implementation.

• Social learning is an important component of our work.
