Re-Carbonation of Concrete Emissions sink modelling for the UK Greenhouse Gas Inventory (GHGI)

Descriptions

**THIS IS A NOTICE OF AWARD ONLY - NOT A CALL FOR COMPETITION** *The final date and time for the submission of bids is 11am Monday 21st June 2021* DO NOT apply directly to the buyer. All tender information MUST be submitted through the Delta eSourcing Portal This work is in support of the National Atmospheric Emissions Inventory (NAEI). The NAEI quantifies national emissions of a range of greenhouse gases and air quality pollutants. This information must be reported annually as the UK Greenhouse Gas Inventory (GHGI) and the UK Air Quality Pollutant Inventory (AQPI), to fulfil the UK's national and international reporting obligations on climate change and air quality. The key output of the NAEI is the provision of high quality and consistent assessments of temporal trends and spatial patterns of emissions for national policy and public information. The aim of this work is to produce a new model to estimate the size of the GHG emissions sink due to re-carbonation of concrete which will improve understanding of this process and contribute cutting-edge science to the UK's greenhouse gas inventory. This work is part of BEIS annual inventory improvement programme that commissions research and development projects to improve and develop the NAEI. The programme aims to improve our understanding and the quality of historic emissions, reduce uncertainties in emissions estimates, and improve our ability to assess progress towards international and national targets. Therefore, work commissioned under the Improvement Programme must: •Be able to develop and provide new methodologies and research; •Accommodate amendments to reporting obligations; and •Be able to be incorporated into the emissions database and annual reporting. •Work with the inventory agency in applying the model to the inventory and produce a detailed write-up of the methods used for potential, future inclusion in the UK's National Inventory Report (NIR). The successful Bidder is expected to meet the specified objectives, incl. (not exhaustive) - identify reliable sources of data, identify/develop appropriate emissions factor data for estimating the size of the emissions sink, develop/verify a model of emissions confirming to a tier 2-standard that calculate the size of the annual greenhouse gas sink and produce a methodology document describing methods used to create the model How to Apply UK Shared Business Services Ltd (UK SBS) will be using the Delta eSourcing Portal for this procurement.
