The Mayor, his climate budget & the impacts

The London Assembly agreed a motion in December 2018, calling for “the Mayor to declare a Climate Emergency, supported by specific emergency plans with the actions needed to make London carbon neutral by 2030 …”.1

The following month, the Mayor declared a climate emergency for London and has brought forward the target for London to be net zero from 2050 to 2030.2

The Greater London Authority (GLA) states that:

“A climate budget is a governance system that mainstreams climate considerations into decision making via the budget allocation process and highlights a city’s short-term actions to deliver the long-term climate targets (in line with the city’s climate action plan or Net Zero Pathway).”3

Tomorrow, the London Assembly Budget and Performance Committee will meet to examine the impact of the Mayor’s Climate Budget and Green Finance Fund, and the impact this has had on achieving London’s net zero 2030 target.

Guests include:

Panel 1—Climate Budgeting

  • Heidi Sørensen, Head of the Agency for Climate, City of Oslo
  • Professor Carly McLachlan, the Director of The Tyndall Centre for Climate Change Research at Manchester University
  • Mark Johnson, Public sector lead, Association of Chartered Certified Accountants

Panel 2—Climate Budgeting and Green Finance Fund at the GLA

  • Fay Hammond, Chief Finance Officer, GLA
  • Pete Daw, Head of Climate Change, GLA
  • Megan Life, Assistant Director of Environment and Energy, GLA
  • Sam Longman, Head of Sustainability and Corporate Environment, Transport for London
  • Kenroy Quellennec-Reid, Head of Impact Investment and Analysis, London Treasury, GLA 

The meeting will take place on Wednesday 19 March from 10am, in the Chamber at City Hall, Kamal Chunchie Way, E16 1ZE.

Media and members of the public are invited to attend.

The meeting can also be viewed LIVE or later via webcast or YouTube.
