Challenges

Help find solutions to some of the world’s toughest climate challenges

Mobility

Until now, the transport industry has been the most resistant to emissions progress. At the same time, cities are key in tackling this challenge as they are faced with the mobility trilemma of clean air, carbon, and congestion whilst facing ever increasing demands to move people and goods around.

Retrofitting

Buildings play a crucial role in mitigating climate change and are directly linked to the resilience of future neighbourhoods, districts, and cities. There is an urgent need for cities to bring about a significant increase in current retrofit rates to realise the "well below two degrees" Paris goal.

Circular economy
