Building a sustainable future requires us to break new ground. Chemical production processes are still too intensive in terms of fossil energy and CO₂ emissions. But chemicals are the building blocks for just about everything we use from mobile phones to shower gel. They are also vital for the new technologies we will need to achieve net zero, from EV batteries to hydrogen electrolysers.

Cities require the most investment and face the biggest risks in the climate emergency. But how can we make sure that they are at the centre of the growing conversation around finance for climate action? The House Live sat down ahead of COP27 with a panel of experts from C40 Cities and WSP to hear what a major new report tells us about unlocking the finance potential of cities to play a greater role in meeting the climate change challenge.
