|Description=In the United Nations climate negotiations, urgent action was called for to limit global warming to 2 °C. In order to achieve this climate goal, countries have proposed short- and long-term actions, both within the UNFCCC climate negotiating process and in domestic policies. To support climate policymakers, the IMAGE model is able to quantitatively evaluate and address different kinds of policy questions. For this, the IMAGE model is mostly used in conjunction with the FAIR model. The FAIR model is a decision-support tool to analyse the costs, benefits, and climate effects of mitigation regimes, emission reduction commitments, and climate policies. | |Description=In the United Nations climate negotiations, urgent action was called for to limit global warming to 2 °C.

FAIR interacts with various parts of the core IMAGE model: mitigation cost curves for the energy sector are derived from the energy [[TIMER model]] (see also [[Energy supply and demand]]) and land-use-related mitigation options are formed by the earth system model ([[Vegetation, hydrology and agriculture]]). Information from FAIR on marginal abatement costs and reduction efforts per sector and greenhouse gas are used as input into IMAGE to evaluate the impacts under different climate mitigation assumptions. FAIR and the IMAGE core share the same simple climate model ([[Atmospheric composition and climate]]). | FAIR interacts with various parts of the core IMAGE model: mitigation cost curves for the energy sector are derived from the energy [[TIMER model]] (see also [[Energy supply and demand]]) and land-use-related mitigation options are formed by the earth system model ([[Vegetation, hydrology and agriculture]]).

Key policy issues
- What global greenhouse gas emissions pathways would meet the well below 2 °C climate target?
- What is the effect of effort-sharing approaches on regional and national emission reduction targets and on the cost of climate policies?
- What is the effect of the NDCs on achieving the long term 2 ºC target?
- What are the trade-offs between mitigation costs, adaptation costs, and climate change damage?
