Assembly calls on the Mayor to declare a Climate Emergency

06 December 2018

The government should give the Mayor of London more powers to ensure London is carbon neutral by 2030.

Today, the London Assembly called on the Mayor to put an emergency plan in place and declare a Climate Emergency in London.

Caroline Russell AM, who proposed the motion said:

“Catastrophic climate breakdown might be as little as twelve years away – this would have profound impacts on every aspect of our lives in London from flooding and overheating in summers, disruption in our food supply chains as well as in the wider natural world.  

“The Mayor need to be at the forefront of this challenge, declaring a climate emergency and an urgent updating of his carbon reduction targets to make London carbon neutral by 2030, decades ahead of his current plans, setting a precedent for other major and world cities.”

The full text of the motion

This Assembly notes that the IPCC’s Special Report on Global Warming of 1.5°C, published in October 2018, describes the enormous harm that a 2°C rise is likely to cause compared with a 1.5°C rise, and confirms that limiting Global Warming to 1.5°C may still be possible with ambitious action from national and sub-national authorities and others.

This Assembly notes the Mayor’s climate change mitigation and adaptation responsibilities and recognises that he aims to make London a zero-carbon city by 2050 and would welcome further ambitious steps.

We welcome action by Bristol city council and other city councils around the world to declare and commit resources to tackling a ‘Climate Emergency’.

We urge the Mayor to declare a Climate Emergency, supported by specific emergency plans with the actions needed to make London carbon neutral by 2030, call on government to give him the powers and funding to make this possible and, as vice chair of the C40 Cities network, to be a leader on this agenda.
