Climate Change Modelling and the WRMP

Reference: 18/CL/04/16
ISBN: 1 84057 862 9
Published Date: 09/11/2018

This Guidance reviews current climate change evidence and methodologies and proposes a new approach for WRMP 2024 designed to be used with the forthcoming UKCP18 climate projections. The existing 'top-down' approach to climate change is resource intensive and has led to significant investment to understand how systems respond to different climate exposures. In advance of WRMP 2024, this project has sought to build upon this understanding and has developed a 'bottom-up' approach framed in the context of system resilience to droughts. An online tool accompanies the Guidance to enable practitioners to apply the approach to quickly evaluate new climate change evidence and identify any scenarios for subsequent analysis, where appropriate. Using ten contrasting case studies, the Guidance demonstrates how the approach and tool can be used to assess new climate change evidence in a proportionate, targeted and system specific manner and communicate the results to stakeholders.

Planning for, and Responding to, the Mean and Extremes of Weather - Technical Report

Reference: 15/CL/01/23
ISBN: 1 84057 779 7
Published Date: 23/07/2015

This project sought to establish quantifiable links between extreme weather events and their impact on operations and assets in relation to service. Following a series of consultation exercises, literature review and voting, 15 perceived linkages between weather and performance were analysed.

Of the 15 linkages analysed, 13 demonstrated that the hypothesis of weather impacting performance was true, 8 resulted in the development of algorithms and 1 resulted in an algorithm with good predictive potential without further analysis. All linkages would benefit from further analysis with more data (performance and weather), and further investigation into weather-driven and non-weather-related causal factors for the responses.

Correlations have been compared with climate change projections from the latest available science to provide an indication of how the performance in these linkages might change in the future. For one linkage, a worked example has been prepared that illustrates how the predictive model can be used to make estimates of energy costs in the future using the UKCP09 Weather Generator.

Workbook for Estimating Operational GHG Emissions, Version 9

Reference: 15/CL/01/22
ISBN: 184057 758 4
Published Date: 08/04/2015

The UKWIR Carbon Accounting Workbook (CAW) provides UK water companies with a consistent and transparent approach for accounting greenhouse gas (GHG) emissions from their annual operational activities. The latest version (CAW v9) enables the water industry to continue to calculate its operational emissions using up-to-date guidance and regulations on GHG accounting in the UK and to report to regulatory bodies and customers.

To align the CAW outputs with new company targets and reporting requirements, additional functionality was added to apply user-defined electricity emission factors and to report emissions for each of retail and wholesale water and wastewater accounts separately.
