IEA EGRD Workshop: Technologies and innovations for the climate-neutral city
Organizer
The event was organized by the IEA Experts Group on R&D Priority-setting and Evaluation (EGRD) in collaboration with the Austrian Federal Ministry for Innovation, Mobility and Infrastructure (BMIMI) and the "Decarbonization of Cities and Communities" program (IEA Cities TCP).
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.
