Summary of the contracting process

The Department for Energy Security & Net Zero is spearheading the Greenhouse Gas Inventory Improvement Programme - 2, aiming to advance research services that enhance UK's GHG inventory in alignment with IPCC guidelines. Centrally located in London, the department is currently at the planning stage, with an engagement milestone scheduled through a Supplier Engagement Call on Friday 24th October 2025 from 10 AM to 12 PM GMT. Interested parties need to register by 4 PM GMT on 23rd October 2025, with the market engagement event set to take place the same week. The programme wishes to employ multidisciplinary research methods to ensure a robust, transparent, and enhanced GHG inventory, with anticipated contract duration from 1st August 2026 to 31st March 2030.

This tender provides significant opportunities for businesses with expertise in climate science, emissions modelling, and international emissions reporting standards. The programme is conducive to small and medium-sized enterprises (SMEs), as well as voluntary, community, and social enterprise (VCSE) organisations due to the collaborative and multidisciplinary nature of the research efforts required. Engaging with this procurement process allows businesses to contribute to vital national and international climate initiatives, while also benefiting from £4.3 million GBP in net value, expanding their operational scope and influence in the environmental sector.

Notice Title

Greenhouse Gas Inventory Improvement Programme - 2

Notice Description

The market engagement slides have been shared with those who registered interest on the participation form. If you would like a copy, please email internationalclimateandenergy.procurement@energysecurity.gov.uk to request them. We are finalising the responses to the Q&A which will be published shortly. The slides and Q&A document will also be published alongside the ITT and UK4 notice. 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. The programme will require a multidisciplinary team 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. DESNZ is holding a supplier event on MS Teams on Friday 24th October 2025 from 10 AM -12 NOON GMT, consisting of presentations by DESNZ and interactive feedback sessions.
