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.
