Products and publications

NAVIGATE will synthesize its advances towards the next generation of IAMs in a range of different products, including reports, publications, teaching material, documentation and databases

NAVIGATOR: A toolbox for accessing IAM resources and results developed during the course of the project. The objective of the IAM NAVIGATOR is to foster uptake of IAM advances and new policy insights by users, experts in related fields, and the IAM community itself.

It contains three main sections:

  • LEARN about integrated assessment modeling
  • USE integrated assessment modeling results
  • APPLY new methods and tool

Synthesis report

The synthesis report will be drafted towards the end of the project. The report will collect newly-gained policy insights with a focus on what can be learned about supply vs. demand side mitigation strategies as well as short-term climate policy entry points for the EU and the world to deliver on the Paris Agreement. This synthesis report will be tailored to feed into the global stocktake of NDCs in 2023 and related EU climate policy discussions at that time, including the implementation of the EU’s mid-century decarbonisation strategy.
