The CCC's advice on the level of Sixth Carbon Budget in the 2030s was accepted by Government in 2021 . Meeting the Sixth Carbon Budget and the longer-term Net Zero target by 2050 requires contribution from all sectors of the economy, including the agriculture and land use, land use change and forestry (LULUCF) sectors. This will require a transformation in how land is used in the UK, with land released out of agricultural production for alternative uses such as afforestation, peatland restoration and bioenergy crops. Under the Balanced Pathway, we estimated that 9% of agricultural land would be needed to deliver these measures, rising to a fifth by 2050. In addition to climate change mitigation, transforming land use can deliver other multiple objectives, including adapting to climate change, biodiversity, and other environmental goals. The CCC's third Independent Assessment of UK Climate Risk (CCRA3) identified eight priority risk areas that the Committee identified as being critical for adaptation in the next two years, four of which relate to the natural environment and the use of land. Effective action to change land use before projected climate change impacts occur must be investigated to enable land managers to protect and enhance the land's ability to maintain the delivery of essential ecosystem services. Our analysis to date has focused on estimating the impact of land use change and management on carbon and GHG emissions at the national level (i.e. England and each of the devolved administrations (DAs)). In practice, the changes that are needed to mitigate and prepare for climate change will vary across different locations according to a range of climatic, economic, social and environmental factors, at the farm, catchment and landscape level. The aim of this project therefore is to identify and quantify the impact of a set of plausible land use transitions for a number of representative rural land use 'archetypes' in England and the UK's DAs out to 2035 and 2050. The transitions should focus on changes in land use and management that deliver increased carbon sequestration and GHG emissions reductions, and which can also contribute to climate resilience, maintenance of food production, increased biodiversity and deliver co-benefits such as access to nature. In some cases, there may be trade-offs, and these should also be identified. In future, the CCC expect to develop full spatial scenarios for UK land-use change that deliver across the multiple objectives. This project does not aim to develop these spatial scenarios, but it will be used to inform any such future work. *** See soecification for more information ***

The CCC's full range of past reports are available here: Publications - Climate Change Committee (theccc.org.uk) 2 Background Local authorities - delivering Net Zero and climate resilience The planning system is the key lever that local authorities hold to shape developments in their regions. This can impact the design of communities, in particular the extent to which their buildings, transport systems, and land align to the pathways required to meet Net Zero and adapt to the changing climate. The present National Planning Policy Framework (NPPF) does include objectives which emphasise that local plans should consider sustainability and climate impacts. However, these are ill-defined in comparison to other objectives (e.g. housing) and there is currently significant variation between local authorities in how they are being implemented. The CPRE (Campaign to Protect Rural England) recently undertook a piece of research that explored 24 local plans outside Greater London, concluding that climate is not generally being considered as a central priority in the vast majority, and that changes to the NPPF are needed to make clear what local authorities are expected to do to ensure that their plans are compliant with the wider Net Zero strategy. Our project should seek to build upon this work by trying to understand what specific barriers hinder better alignment between local plans and sustainability objectives, and how these should be overcome. Several other recent studies explore how the planning system can play a key role in delivering Net Zero: • Green Alliance's 2020 paper on the local climate challenge highlighted a misalignment of priorities in the planning system, as well as practical difficulties around the appraisal tools used and the powers available to local authorities. • The use of these tools was explored in more detail in UK100's 2021 report on local authority powers. • The Centre for Cities set out a vision for improved spatial planning to enable lower carbon community development in its 2021 work Other recent reports have produced adaptation guidance based on the NPPF and National Adaptation Programme (NAP) for local authorities. However, there is currently no mandatory requirement for local authorities to report on adaptation, and a lack of research combining the practical and structural barriers for delivering this guidance and recommendations for aligning adaptation/mitigation: • ADEPT, Defra and Local Adaptation Advisory Panel Guide • Town and Coastal Planning Association Adaptation guide • Local Partnerships Climate Adaptation Toolkit, which summarises the risks highlighted by the 3rd Climate Change Risk Assessment for local authorities. *** See Specification for more detail ***

The Climate Change Committee (CCC) is looking to widen its understanding of policy responses that both address recent economic pressures on households and businesses and deliver potential for accelerated emissions reduction. In addressing the increases in household and business costs that have resulted from energy prices pushing up the rate of inflation, Government should seek to identify options that also contribute to the UK's decarbonisation goals. Many countries are introducing policies with these dual aims in response to similar challenges and learning lessons from their efforts can inform a well-targeted policy response in the UK. The CCC is looking to analyse the international policy landscape in several key sectors, including buildings and transport. To inform this work, the CCC is tendering a project 1) to establish an up-to-date summary of the key policies, including where relevant those targeted primarily at shifting behaviours, 2) where possible, evaluating (both quantitively and qualitatively as appropriate) these policies against a set of pre-determined criteria and analysing their potential effectiveness in a UK context and 3) identifying where and why potential cost-saving climate policies exist but have not been pursued in the UK and suggesting policies that would fill these identified gaps. Given the fast-paced nature of the crisis, the tendered work needs to be delivered by 19/04/2023, at a cost of £40,000 - £50,000 excluding VAT.

1 Introduction and summary of requirements / Preamble The Climate Change Committee (CCC) is an independent, statutory body established under the Climate Change Act 2008. Our purpose is to advise the UK and devolved governments on emissions targets and to report to Parliament on progress made in reducing greenhouse gas emissions and preparing for and adapting to the impacts of climate change. The aim of this project is to expand our understanding of the historical extent of energy efficiency retrofits, identify current market trends, and assess the capacity for existing supply chains to grow and deliver the volume of retrofits implied by our Sixth Carbon Budget Pathways. 2 Background Across the UK, the number of energy efficiency measures installed in homes through government-backed schemes peaked in [2012]. Since then, installations have fallen significantly. The Government's target is for all UK homes to be at least EPC C by [2030]. However, at the current rate of progress this target will not be reached for decades. There is good data available which describes the number of households that have received energy efficiency improvements through government schemes, such as the Energy Company Obligation (ECO), the Green Deal Framework, the Green Homes Grant Local Authority Delivery Scheme (LAD) and the Social Housing Decarbonisation Fund (SHDF). However, we lack similar information about the extent of retrofits undertaken by owner occupiers, landlords and others without government backing. Rising energy prices have improved the economic case for energy efficiency. Reducing energy waste from homes is also an essential step to reduce emissions from buildings and reach Net Zero. As we (the CCC) are preparing work for our 2023 Progress Report, and the Seventh Carbon Budget, we want to update our approach to assessing the state of domestic energy efficiency. This entails developing a more comprehensive understanding of the current state of energy efficiency in UK homes, and the path the market has taken over the past fifteen years. We want to understand the remaining potential to improve homes, and the capacity within the market to grow supply chains to meet this need. We are tendering a project to develop this understanding. The tendered work needs to be delivered by [19/04/2023], at a cost of £32,000 - £40,000 excluding VAT.

1 Background The Climate Change Committee The Climate Change Committee (CCC) was set up as part of the Climate Change Act. The CCC is an independent body that advises both on reducing emissions in the UK and adapting to the climate changes in the UK. The CCC's full range of past reports are available here: http://www.theccc.org.uk/reports/. The UK Climate Change Risk Assessment Under the Climate Change Act 2008 (section 57), an assessment of the risks facing the UK from the current and predicted impact of climate change is required every 5 years. The CCC is responsible for providing independent advice to the UK Government to inform that assessment. The Committee has recently provided its advice to the UK Government on the risks and opportunities facing the UK from current and future climate change as part of the third Climate Change Risk Assessment (CCRA3) - this was summarised in its Independent Assessment of UK Climate Risk which was published in summer 2021. The fourth UK Climate Change Risk Assessment (CCRA4) is due for completion by June 2026. CCRA4 will assess climate change risks to the UK using a more spatially defined approach than previous CCRAs, giving an assessment of the spatial distribution of climate risks across the UK and a more localised view of adaptation needs. In order to assess climate risks at a spatial scale in CCRA4, the CCC are seeking to identify existing spatial modelling tools, initiatives and datasets that can be used to assess the spatial distribution of climate risks across the economy and the natural environment. 2 Aims and Objectives The aim of this project is to review the current landscape of spatial modelling of climate risks to the UK. This project will seek to identify existing models capable of UK-wide spatially explicit climate risk assessment within different sectors and ongoing modelling initiatives producing spatially explicit outputs relevant to UK climate risk assessment. The purpose of this exercise is to understand what tools and existing simulations could be used to inform spatial risk assessment in CCRA4. **** See specification for more details **** Additional information: Please note the change in closing date from 5pm on Wednesday 25th January 2023 to 11:59pm 29th January 2023

Background The Climate Change Committee   The Climate Change Committee (CCC) was set up as part of the Climate Change Act. The CCC is an independent body that advises both on reducing emissions in the UK and adapting to climate change in the UK.   The CCC's full range of past reports are available here:    http://www.theccc.org.uk/reports/.   The UK Climate Change Risk Assessment          Under the Climate Change Act 2008 (section 57), an assessment of the risks facing the UK from the current and predicted impact of climate change is required every 5 years. The CCC is responsible for providing independent advice to the UK Government to inform that assessment.   In summer 2021, the Committee provided its advice to the UK Government on the risks and opportunities facing the UK from current and future climate change as part of the third Climate Change Risk Assessment (CCRA3). This was summarised in its Independent Assessment of UK Climate Risk.   The Committee's advice on the fourth UK Climate Change Risk Assessment (CCRA4) is due for completion by June 2026. CCRA4 will aim to assess climate change risks to the UK using a more holistic, sectoral approach than previous CCRAs, so that the interactions between risks and the co-benefits of different adaptation actions may be better understood. In particular, the outputs of CCRA4 will include a 'Well-adapted UK' report that will aim to synthesise in-depth, systemic assessments of the risks to key areas of the economy and society, as well as the interdependencies and cross-cutting interventions between these, bringing together a strategic case for adaptation action. We intend to base these systemic assessments on tailored, in-depth and quantitative modelling commissioned by the CCC, as well as the wider published evidence base. To ensure that the outputs of these assessments - and hence the outputs of CCRA4 - are as useful as possible for the priority audience of Government stakeholders and decision makers, the specifications for the modelling will be co-developed with these stakeholders. By tailoring the research to end-user and decision-maker need, CCRA4 aims to be well placed to drive adaptation action. The co-development of the outputs and evidence base will continue throughout the CCRA4 cycle, but the first step is to build an initial understanding of stakeholder priorities and where the proposed in-depth, systemic assessments can add most value and how. In particular, this first phase of engagement with stakeholders will help to inform the topics and sectors that will be the focus of tailored modelling projects going forwards, by highlighting where such research would be feasible and where it would add most value for driving adaptation action. **** See Specification for more detail **** Additional information: 19.05.23 - Please see attachment SW-0523 The CCC would like to clarify some of the details of this specification following queries from potential suppliers. We recognise that the timescales for this project are very challenging and that there is a need to be mindful of what can feasibly be achieved within the project timelines. For example, we recognise achieving full consensus within working groups may not be possible and the detail of the recommendations in task 5 will be limited by the detail of the working groups' discussions. With this in mind, we want to ensure a quick start is possible following kick-off and that workshop discussions are not starting from a blank page. To facilitate this, the CCC will provide: • Attendees lists for the workshop. The CCC will be responsible for contacting and liaising with attendees and managing attendance, recognising the importance of having the right stakeholders present. Finalised dates for workshops will be agreed with the contractor at kick off but attendees will be approached in advance of this. • Pre-workshop briefing materials. The pre-workshop briefing materials prepared by the CCC and shared with attendees will include background material on the project as well as sector specific information on possible objectives, risks, hazards, exposure, vulnerabilities and adaptation actions derived from the CCC's adaptation monitoring framework and the UK's third climate change risk assessment (CCRA3). In addition to preparing workshop attendees, the CCC will use these materials and wider preparatory work to set the scope for workshop discussions and inform the workshop agendas alongside suppliers' bids. Bidders' suggestions for how the tasks should be structured will be welcomed alongside this input from the CCC. This includes suggestions for the use of the optional workshops but the timescales in the specification will need to be adhered to. • Consultation on recommendations. The recommendations required in task 5 will be produced in consultation with the CCC, noting the detail of these will be limited by the scope of working group discussion. The recommendations should focus on which sectors, or areas within those sectors, should be prioritised, rather than details of potential modelling approaches, although such details are useful to record when they arise. The CCC will be using the recommendations alongside the outputs of other research projects and broader information to come to a final decision on what sectors to prioritise for more detailed sector analysis. Consultation with the CCC and any learning that can feed into the recommendations should develop and be communicated on an ongoing basis as the project progresses.

Wastewater treatment emissions are a small proportion of total UK emissions, but this proportion increases by 2050 in our Sixth Carbon Budget scenarios, as other sectors largely decarbonise while wastewater emissions only fall by a small amount. Assumptions on emission reductions from wastewater in our Sixth Carbon Budget scenarios were based on academic papers and discussions with academics and stakeholders in the water industry. This resulted in emission reductions of 20% by 2030 in three of our scenarios, including the Balanced Pathway. This increased to a 50% reduction by 2050 in two of our scenarios (Widespread Innovation and Tailwinds). The main solutions assumed to deliver this abatement were: • Across all scenarios - conversion of wastewater treatment plants to advanced anaerobic digestion systems (increasing the amount of biogas extracted and reducing methane emissions) and process optimisation improvements and leak identification using on-site emissions monitoring of CH4 and N2O. • More ambitious scenarios - more innovative options such as membrane-aerated biofilm reactors or partial nitrification-Anammox processes. Water companies in England and Wales submitted their draft business plans to Ofwat in October 2023. These plans are going through an ongoing verification process, so are subject to change, but include plans for wastewater treatment out to 2034, with associated emissions pathways. Aggregate wastewater emissions in draft plans are relatively steady over the period in question - differing significantly from the 20% reduction assumed in our Balanced Pathway. There is significant variation between individual water companies, with changes in emissions over the period ranging from a 60% reduction to an 50% increase by 2034, relative to 2021/22 levels. **** See Specification for more details ****

1 Introduction and summary of requirements The Climate Change Committee (CCC) is an independent, statutory body established under the Climate Change Act in 2008. The CCC has been commissioned by the Department for Environment, Food and Rural Affairs to conduct the Fourth UK Climate Change Risk Assessment Independent Assessment (CCRA4-IA). This will assess the risk the UK faces from Climate Change across society and the economy and the potential adaptation actions that could be taken. We are looking to conduct this assessment at as narrow a spatial level as possible. 2 Background The CCC is currently collecting evidence and preparing its advice for the Fourth Climate Change Risk Assessment Independent Assessment (CCRA4), due for publication in 2026. This will look to assess the risks the UK faces today and in the future. It will also look to update the priority scoring of risks from CCRA3. It will assess adaptation actions that can be taken to reduce these risks. A key output the CCC is looking to produce for CCRA4 is the assessment of risk by household, business and local area/community characteristics. This project is looking to build the evidence of vulnerability under these three categories to facilitate this assessment. We require a contractor to produce a vulnerability dataset to be used within CCRA4 commissioned and in-house analyses. This dataset will be a key input into our research and will need to give an up-to-date spatial mapping of key vulnerabilities to climate change impacts across the UK and an indication of future vulnerabilities. 3 Aims and Objectives The CCC is looking to generate a database of indicators of vulnerability against climate change risks (as identified by CCRA), geographically mapped across the UK (including the Devolved Administrations (DAs) of Scotland, Wales, Northern Ireland and inhabited islands). The dataset should capture the key characteristics of households, businesses and local communities/economies that could drive vulnerability to the risks identified in CCRA3. These include: *** See Specification for more detail **** Additional information: 12.03.24 - Update 12th Mar - closing date changed to 28th March 2024 12.04.23 - Revised documents with only a revised closing date

The CCC is currently collecting evidence and preparing its advice for the Fourth Climate Change Risk Assessment (CCRA4), due for publication in 2026. This will look to assess the risks the UK faces today and in the future, and assess adaptation actions that can be taken to reduce these risks. As part of CCRA4, we will be developing a new output to complement the Technical Report, as produced in previous CCRAs and assesses the range of risks and opportunities facing the UK from climate change and the urgency for adaptation in the next five years. This output - to be known as the 'Well-adapted UK report' (WA report) - will focus on the potential for key adaptation actions to reduce the climate risks threatening the achievement of key UK policy and societal outcomes and hence set out a vision for aspects of a well-adapted UK. The WA report aims to provide a policy-relevant evidence base on effective systemic adaptation scenarios, their costs and benefits (and how these are distributed across society) and the investment needs to deliver on them. One aspect of the WA report will consider the resilience of particularly critical sectors in the UK, and to inform these assessments we are commissioning analysis to assess the required level of resilience to minimise future rising risks associated with climate change, including quantification of a cost-optimal level of resilience. One of the areas we are assessing in depth is the resilience of cold supply chains in the UK. We would like to better understand how climate change could disrupt the UK's supply of essential goods that rely on a temperature-controlled supply chain. Specifically, we are interested in assessing the exposure, vulnerability, and resilience of the UK cold chain to temperature related climate hazards and evaluating cost optimal adaptation measures for the sector. We anticipate that the scale and complexity of the UK's cold supply chain will be difficult to analyse effectively in its entirety, so we propose developing a 'component analysis' which looks in depth at a range of tangible 'parts' of the supply chain to help build a national level picture of risk exposure and paths to resilience. We will be commissioning this research in two parts. The purpose of this specification is to commission Part 1 - a scoping study to develop the evidence base through a 'component analysis' covering a range of specific 'parts' of the cold supply chain which would be assessed in detail in a potential follow-on study (Part 2 - to be commissioned separately following completion of this scoping study). **** See Specification for more detail **** Additional information: UPDATE - 08.05.24 - Revised Specification - no changes to content other than to align closing date to the 16th May 24
