Built environment consultancy Arup has renewed a partnership with a climate group to drive down emissions in cities worldwide.

The deal with C40 Cities Climate Leadership Group (C40) will see Arup commit $3m of advisory support over three years, in which time it will work with C40 on programmes to improve energy efficiency, reduce waste and encourage a move towards a more circular economy.

Arup and C40 will explore how consumption patterns in cities need to change and how data can support decision making and the monitoring of progress against climate action plans.

Arup Group chairman Gregory Hodkinson said: “With more than half of humanity living in cities, they with their mayors are vital actors to bring about genuine change in support of the Paris Agreement. Through collaboration and the sharing of knowledge, we can work together to ensure that cities can play their parts in preventing dangerous climate change.

“More needs to be done to help city leaders with their programmes to reduce emissions and better adapt their populations to the very real threats posed by climate change.”

C40 Executive Director Mark Watts said that when the Paris Agreement was signed in 2015, “C40 and Arup immediately set to work calculating what the deal and the 1.5 degrees global warming target meant for the world’s great cities. Thanks to that ground-breaking analysis, more than 70 C40 cities are now developing climate action plans consistent with the emissions cuts that science tells us are needed to prevent catastrophic climate change.”
