Documentation

Cities are key players in the fight against climate change. They account for 75% of global CO2 emissions and 78% of worldwide energy consumption, but they also hold immense potential to drive new solutions and pathways toward a sustainable future.

This workshop, organized by th IEA Experts Group on R&D Priority-setting and Evaluation (EGRD) focused on how cities can achieve climate neutrality. The discussions centered on key factors for R&D policies to foster technologies and systemic innovations for sustainable and resilient urban development.

Key questions

  • How can cities achieve the goal of climate neutrality? What are the key challenges and main risks?
  • What are the resilient transformation paths for the system innovation for the future?
  • New technologies and new business models: Where do we stand and what is needed?
  • Which instruments and activities must be supported? Which are the main factors to be considered regarding R&D policies and decision making?

Outcomes

The workshop highlighted key challenges and opportunities and provide concrete recommendations for the development of climate-neutral cities.

The executive summary of the workshop will be published soon.
