UK Public Sector Contracts & Tenders

DESNZ is seeking to procure a supplier(s) to deliver and lead the second UK Greenhouse Gas (GHG) Inventory Improvement Programme of research (IIP-2). The research programme will involve an organisation with expert technical understanding of inventory issues as they relate to issues across the UK economy leading a consortium to develop methodologies, deliver sector-specific original research and engage relevant stakeholder, generating new or updated emission factors and activity data. This will continue to ensure that the UK GHG inventory is in alignment with Intergovernmental Panel on Climate Change guidelines and reflects government decarbonisation efforts. This programme is being published as two procurements. This one is the  Energy, Waste, and Industrial Processes and Product Use (IPPU) emissions reporting sectors. Refer to Page 55 of the ITT Document Both programmes will require a multidisciplinary teams with expertise spanning but not limited to climate science, mathematical emissions modelling, IPCC guidelines, UNFCCC accredited experts and international emissions reporting standards, specifically as applied to sectoral processes (excluding the agriculture sector but a knowledge of the agriculture sector is essential). In addition, a dedicated programme management office will be essential to coordinate and oversee delivery. To ensure comprehensive and high-quality outcomes, the programme will employ a blend of qualitative, quantitative, modelling, and collaborative research approaches. These will include desk-based analysis, stakeholder engagement, laboratory testing, model and methodology development, fieldwork, and rigorous QA/QC procedures. The intended outcome is a scientifically robust and transparently enhanced UK GHG inventory. The inventory will be more resilient to future changes and capable of quantifying emissions uncertainty in a reproducible and interpretable manner. It will also improve the representation of emissions from diffuse sources, using open and transparent models and methods that allow for the identification and correction of risks and weaknesses.

CASA3 is a strategic International Climate Finance (ICF) programme that strengthens the capacity and capability of climate-vulnerable developing countries to participate effectively in international climate negotiations. The programme contributes directly to UK Government priorities by supporting ambitious, inclusive and rules-based international climate negotiations, enabling developing country partners to engage as progressive voices within the United Nations Framework Convention on Climate Change (UNFCCC) and associated multilateral forums.

The final date and time for the submission of bids is Wednesday 7th October 2026 at 11:00 DO NOT apply directly to the buyer. All tender information MUST be submitted through the Jaggaer eSourcing Portal. Brief Description of Requirement Phase 1 The objective of phase 1 is to assess the safety and risk considerations for deployment of up to 800 W AC mains output plug-in batteries in the UK context with acceptable electrical and fire safety risk. The study will inform technical standards adaptations and assess the feasibility of safe, plug-in batteries for UK domestic use. A relevant set of installation configurations will need to be considered in scope of the fire and electrical safety tests and will be finalised as part of the test protocol development for the study, in consultation with relevant stakeholders. These installation configurations may include individual plug-in batteries, plug-in battery DC-coupled to plug-in solar with a single hybrid inverter, multiple plug-in batteries DC-coupled in series, and multiple plug-in batteries DC-coupled in parallel. An illustrative set of installation configurations that might be expected to be considered by the supplier when developing the test protocol are provided below, noting that the tests should focus on the standalone plug-in battery products and/or the plug-in battery to plug-in solar interface rather than the wider domestic environment in which they are located.

DESNZ is seeking to procure a contractor to provide research services for a four-year Biomass Research Programme. The programme will advance scientific understanding of the role and potential of biomass and bioenergy in supporting climate change mitigation, enhancing energy security, and de-risking the delivery of net zero. It will include research on: Lifecycle greenhouse gas emissions of biomass feedstocks and bioenergy systems Biomass availability and demand across sectors Sustainability criteria and environmental impacts Co-benefits and trade-offs including biodiversity, air and water quality Economic modelling of biomass-derived fuels and materials The bioeconomy and its potential for growth and decarbonisation The following skills and expertise are considered particularly important for this work: Geospatial modelling Spatial data analysis Modelling climate scenarios Scientific research Scientific analysis Policy development Economic research The project will additionally require strong project management capability to support the delivery of this research. Outputs are likely to include: Reports, policy briefings, and technical annexes Updated models (e.g. UK & Global Bioenergy Resource Model) Seminars, workshops, and teach-ins Data sets and scenario analyses to inform policy decisions The programme will be delivered through seven work packages (WP), covering: WP1: Programme Management WP2: Biomass Lifecycle Analysis WP3: Feedstock Availability WP4: Biomass Feedstocks for Industry WP5: Biomass Sustainability Framework (with co-benefits & trade-offs) WP6: Analyses of the Bioeconomy WP7: A Flexible Fund for emerging evidence needs DESNZ is holding a supplier event on MS Teams on 13.01.2026, consisting of a presentation by DESNZ followed by Q&A.

All tender information MUST be submitted through the Jaggaer eSourcing Portal. Brief Description of Requirement It is broadly recognised that physical climate risk and related nature dependencies can pose risks to economic and financial stability. Governments and regulators in the UK and internationally have recognised this and continue to take action to address underlying vulnerabilities and support wider systemic resilience. Notwithstanding the clear need for accelerated global action, there remains significant uncertainties in appraising the future economic and financial implications of physical risk meaning market practices, government policy and regulation, may not be optimised (within the bounds of wider limitations and mandates) to align with climate-resilient pathways. Climate scenario analysis is a key tool to inform approaches to climate risk management. But due to the complexity and heterogeneity of climate risk, academic and industry evidence has highlighted that current mainstream scenarios – whilst highly sophisticated – may not capture all potential physical risk due to limited data availability and modelling constraints. Furthermore, whilst reference scenarios continue to be enhanced, some potential hazard exposures and highly complex systems dynamics may not be well suited to quantification through empirically calibrated, top-down damage functions, which provide estimates for economic damages in climate scenarios. There is, therefore, a need to investigate the potential for complementary methodologies to support more holistic approaches to physical risk appraisal and management. This is the focus of this research project. Specifically, research will focus on how local physical climate shocks (e.g. storms, flooding, droughts, heat stress) can - through cascading, compounding, and contagion effects - become systemic risks. There will be a particular focus on furthering understanding of UK vulnerabilities to climate shocks in other countries, with the objective of supporting improvements to industry practices and providing insights for government policy, regulation, and prudential supervision. This research project will be delivered in coordination with the Financial Conduct Authority’s Climate Scenarios Sandbox , with potential for insights generated through the sandbox to provide practical evidence regarding the utility of research outputs. The project will also be delivered in partnership with the recently established UK Taskforce on Climate and Nature Security and will, where possible, be aligned with ongoing work on high-impact climate possibilities at the Climate Financial Risk Forum.
