In September 2019, your Deputy Mayor for Transport said in correspondence with the Stop Silvertown Tunnel campaign that: “the [London climate] trajectory has been independently assessed by C40 to be in line with the advice of the Intergovernmental Panel on Climate Change with the level of carbon emission reduction required to put us on track to staying within 1.5C global warming.” Could you publish this independent assessment, along with related data and correspondence from the Mayor's office and the C40 Cities group?

The zero carbon pathway in the London Environment Strategy was developed based on detailed independent modelling, funded by C40’s Deadline 2020 pilot programme. The key premise of the Deadline 2020 programme was to outline the pace, scale and prioritisation of action needed to deliver on the objective of the Paris Agreement to limit global warming to 1.5C.

Arup was commissioned by C40 Cities Climate Leadership Group to conduct an assessment of the London Environment Strategy and other relevant reports against the pillars of the C40 Climate Action Planning Framework (CAPF). The final assessment was published last summer (18 July 2018) and can be found on our website; see appendix 6 in the “Related documents” section of this webpage: https://www.london.gov.uk/what-we-do/environment/london-environment-strategy

C40 also confirmed that London has developed what they consider to be a Paris Agreement Compatible Climate Action Plan, their letter of confirmation has also been published on our website, see appendix 7 in the “Related documents” section of this webpage: https://www.london.gov.uk/what-we-do/environment/london-environment-strategy.
