Key information

Decision type: Mayor

Directorate: Mayors Office

Reference code: MD3413

Date published:

Decision by: Sadiq Khan, Mayor of London

Executive summary

Investment in deliverables focussed on climate adaptation and greening will serve as a core delivery mechanism for the Mayor’s Delivering a Greener and More Climate-Resilient London programme. 
The project will use key policy frameworks and partnership working to target significant and transformational investment in areas of greatest need. In this way, it will address the city’s most pressing greening and climate-resilience challenges including the delivery of the Clean and Healthy Waterways Plan.
The delivery plan for the Mayor’s Delivering a Greener and More Climate-Resilient London programme, approved under MD3384, reserved approval for this project due to the introduction of new, large-scale funding (in paragraph 1.17). Therefore, this Mayoral Decision (MD) seeks approval to spend up to £7.906m to deliver the project.
 

Decision

That the Mayor:
·    approves expenditure of up to £7.906m across three financial years (2025-28) to invest in deliverables focussed on climate adaptation and greening as part of the Delivering a Greener and More Climate-Resilient London delivery plan 
·    delegates authority to the Assistant Director, Environment and Energy, in consultation with the Deputy Mayor for Environment and Energy, to approve the following without the need for a further decision form: 
o    funding allocations (within the above-mentioned £7.906m), following an assessment process using agreed criteria
o    the receipt and expenditure of any additional funding (internal or external) to enhance, expand or extend the investment focussed on climate adaptation and greening within the same parameters, and after consulting with legal advisers and the GLA’s Chief Finance Officer, and having then secured agreement from the Mayoral Delivery Board.
 

Part 1: Non-confidential facts and advice

1.1.    The Mayor’s ambitious new delivery plan for his Delivering a Greener, More Climate-Resilient London programme (approved by MD3384) describes how the GLA will work with others to improve access to nature and drive climate adaptation while ensuring the benefits are felt equitably across the city. The delivery plan focuses the GLA’s efforts where they are needed most: achieving more equitable access to nature; and supporting Londoners who have contributed relatively little to climate change but are often the most affected.
1.2.    Paragraph 1.17 in MD3384 refers to a new large-scale greening and adaptation delivery project called Investment in strategic projects focussed on climate adaptation and greening (thereafter called “the Project”). It aims to enable the delivery of a small number of strategic, transformational green-and-blue infrastructure and climate-resilience deliverables that support the priorities in the programme mandate. 
1.3.    Deliverables will be identified by leveraging cutting-edge spatial evidence from: 
•    the forthcoming London Green Infrastructure Framework and Local Nature Recovery Strategy
•    the London Urban Forest Plan
•    the London Surface Water Strategy
•    the Heat RiskPlan 
•    the Clean and Healthy Waterways Plan.
1.4.    As a result, the Project will direct resources to places that need them most. Its ambition is to maximise social, ecological and climate-resilience outcomes, ensuring  a more equitable urban environment for all. 
1.5.    This Mayoral Decision (MD) seeks approval to spend up to £7.906m for the delivery of the Project. One-third of the funding will be dedicated to waterways. This MD also sets out the selection process for the deliverables that sit under the Project and their delivery approaches. Decision-making on final deliverables is delegated to the Assistant Director, Environment and Energy, in consultation with the Deputy Mayor for Environment and Energy.

Objectives
2.1.    The Project will contribute to the following London-level outcomes: 
•    Londoners can enjoy green and wild spaces across the capital 
•    London is resilient to extreme weather and the impacts of climate change.
2.2.    The overall objective of the Project is to make London more resilient to climate change, and to ensure that all Londoners, regardless of income or background, can access and benefit from green, blue and wild places. 

The Project
2.3.    The Project will provide investment at various phases of development, including early planning and partnerships; scaling; and delivery. Unlike the competitive application process for Green Roots, the Project will award funding directly to enable the delivery of targeted deliverables where they are most needed. These may be too large-scale or complex for the Green Roots Fund.
2.4.    To select between five and nine deliverables, the evidence sources outlined at paragraph 1.3 have been used to develop a list of strategic investment priorities. Table 1, below, details expected outcome, type of deliverable, and type of location:
Table 1: Strategic investment priorities

2.5.    A set of suitability criteria will be used to support detailed scoping work and identify the specific deliverables that respond to the investment priorities. The criteria will help the GLA determine which deliverables to take forward. 
2.6.    The proposed suitability criteria include the following:
•    transformation: whether the geographic scale is significant, or if GLA investment will bring about significant change, such as unlocking necessary deliverables at scale, innovating and providing replicable models or bringing key stakeholders together
•    deliverability: whether significant progress can be made during this mayoral term
•    additionality: whether GLA involvement will lead to further impact and/or benefits that would not have happened otherwise
•    strategic alignment: whether the deliverable will support GLA strategic priorities identified in mayoral strategies and plans, or mayoral commitments.
2.7.    In addition to the four criteria referenced above, three further considerations will be applied: 
•    geographic spread of deliverables
•    spread across the development phases (i.e., supporting some at an early-stage that need more scoping and feasibility studies, but with the majority at a more mature stage able to begin on the ground delivery more quickly) 
•    GLA resource availability.
2.8.    Alongside direct GLA investment, each deliverable will receive a tailored support package to enhance delivery capacity among stakeholders involved and ensure GLA priorities are embedded. This support will be provided through a mix of GLA officer support and specialist technical delivery support that will be procured by the GLA in accordance with the GLA’s Contracts and Funding Code.
2.9.    As set out in the Delivering a Greener, More Climate-Resilient London delivery plan, the majority of the deliverables will be selected by March 2026. However, any deliverable identified through the forthcoming Heat Risk Plan will be agreed after this date.
2.10.    Funding will be awarded to identified partners in the form of grants (expected to be £500,000 or more per deliverable through phased funding over three years). 
2.11.    To enable the timely allocation of funding, this MD seeks a delegation of authority to the Assistant Director, Environment and Energy, to approve the final list of deliverables and associated funding allocations without the need for a further MD. This would be done with supporting evidence and in accordance with the criteria set out above; and in consultation with the Deputy Mayor for Environment and Energy. The Assistant Director, Environment and Energy, will ensure compliance with the obligations set out in the Openness of Local Government Bodies Regulations 2014, which set out when written records of decisions and their content need to be published. Furthermore, a record in writing will be prepared.
2.12.    It is hoped that the Project will serve as a catalyst for wider change, unlocking additional funding from public and private partners. In all cases, therefore, GLA officers will seek to leverage additional funding from other public and private organisations to increase the total delivery budget. No additional funding is yet confirmed, and any additional funding would likely be awarded directly to partners. 
2.13.    Where additional funding from government (or other sources) is secured and passed through the GLA in the future, to expand or extend existing approved deliverables contained in the Project, and the parameters remain the same, or similar, as originally agreed with funding partner(s), this MD seeks approval to delegate to the Assistant Director, Environment and Energy to agree the receipt of such funding after consulting the GLA’s legal advisers and the Chief Finance Officer without the need for a further decision form. 
2.14.    For the purposes of considering whether the parameters are similar as originally agreed with government (or the relevant body), the Assistant Director, Environment and Energy, will have regard to whether the outcomes to be delivered have changed significantly or there is a significant change in attendant risks of the original scheme. The Assistant Director, Environment and Energy, will ensure compliance with the obligations set out in the Openness of Local Government Bodies Regulations 2014, which set out when written records of decisions and their content need to be published. Furthermore, a record in writing will be prepared.
2.15.    A budget of up to £7.306m will enable delivery over three financial years. An estimated £0.6m, 7.6 per cent of the total budget, will cover technical delivery support for the partners, as referenced in paragraph 2.8. Examples of technical delivery support include advice on funding and finance models; equality, diversity and inclusion; and ecological and climate resilient landscape design to enable faster delivery. Furthermore, it will help address any capability and capacity barriers to delivery such as leveraging funding, local stakeholder engagement, partnership building, governance models, skills development and knowledge sharing. Allocating a proportion of the total budget to a technical delivery support offer where the resources can be shared across all deliverables ensures efficient and streamlined delivery, avoids independent procurement activities and ensures high quality expertise in line with GLA priorities. Any unspent technical delivery support budget will be reallocated to partners as part of the Project delivery grants.
 

 

3.1.    Under section 149 of the Equality Act 2010, as a public authority, the Mayor of London and the GLA must have ‘due regard’ of the need to eliminate unlawful discrimination, harassment and victimisation; and to advance equality of opportunity, and foster good relations, between people who have a protected characteristic and those who do not. 
3.2.    This involves having due regard to the need to remove or minimise any disadvantage suffered by those who share or are connected to a relevant protected characteristic; taking steps to meet the different needs of such people; and encouraging them to participate in public life or in any other activity where their participation is disproportionately low. This can involve treating people with a protected characteristic more favourably than those without one.  
3.3.    The Project outlined in this MD will assist delivery of the policies and proposals in the London Environment Strategy, which has been informed by a full integrated impact assessment, including consideration of equalities. The Equalities Assessment Report for the London Environment Strategy noted that exposure to poor environmental conditions is much higher among Black, Asian and Minority Ethnic Londoners. 
3.4.    Additionally, the forthcoming London Green Infrastructure Framework focuses on targeting social and health inequalities through green infrastructure and climate resilience deliverables. This evidence base will be used to inform priority locations that help to address social and health inequalities.
3.5.    A climate and equalities impact assessment has been completed specifically for the Project and the results will inform Project design and delivery. 
3.6.    The proposed Project outlined in this MD specifically responds to, and aims to tackle, the disparity in how different groups experience nature in London. Some elements of the Project will focus on social and health inequalities, implementing green infrastructure and climate resilience deliverables to improve access to and the benefits from it, particularly for underrepresented groups. 
3.7.    Furthermore, as a condition of funding, delivery partners need to demonstrate how their deliverable will address equality, diversity and inclusion. Each deliverable will also need to demonstrate how it will ensure that, as relevant, that the needs of the local community are included in the design and implementation, and how the relevant groups will benefit from them.
 

4.1.    The key risks and issues are set out in the table below:

The Green Infrastructure and Climate Adaptation teams have built up considerable experience in assessing costings from previous grant funds. This will help establish realistic scopes. The teams will also work with delivery partners to develop cost estimates.

 

Once delivery starts, the teams will continue to monitor inflation (where relevant) and impact on delivery; and work with delivery partners to determine appropriate contingency levels and flex scope as needed over the deliverable lifetime.

Deliverables will be designed collaboratively with delivery partners to ensure the scope is realistic and achievable. The scope and delivery mechanisms will be thoroughly tested and refined with partners before funding agreements are finalised. Throughout design and delivery, GLA officers will work in partnership with delivery partners to identify risks early and provide ongoing support to address capacity and capability challenges. Technical delivery support will be made available to help partners overcome barriers to effective delivery.

Building on the success of previous green infrastructure and climate resilience programmes, and ongoing wider engagement with stakeholders, GLA officers will use these relationships to identify key delivery partners, engaging with them early in the identification process to align on timelines. Additionally, some proposals will be more advanced than others, so budget will be allocated proportionally.
