Climate Change 

Workbook for Estimating Operational GHG Emissions – Version 13

Reference: 19/CL/01/27
ISBN: 978-1-84057-869-0
Published Date: 08/05/2019

UKWIR has developed a standardised workbook for estimating operational GHG emissions, the Carbon Accounting Workbook (CAW), to bring consistency and accuracy to the reporting process across the industry. The workbook has been in place since 2004 and is updated annually to reflect the needs of the industry, including changes in carbon accounting practices. Updated emission factors to align with the latest UK and international data.

The key updates from version 12 to 13 of the CAW are:

Updates of the emission factors to reflect 2018 values

Addition of Hydrogenated Vegetable Oil as a new fuel

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.

Flow modelling of urban water distribution systems using water conservation fittings

Reference: 18/CL/12/3
ISBN: 1 84057 849 1
Published Date: 10/02/2018

The aim of this work was to assess the impact of water conserving fixtures and fittings on UK building drainage (wastewater collection) systems of up to 100mm diameter, ranging from the point where the appliance discharges into the collection drain to the connection to the common sewer.

This involved taking an inventory of water conserving devices currently available, and to quantify the effect that these could have on wastewater collection systems in terms of increased solids residence times and creation of downstream blockages caused by solid waste deposition or other flow problems.

Implementing Ecosystem Services and Natural and Social Capital Accounting Approaches - Phase 1

Reference: 17/CL/04/15
ISBN: 978-1-84057-894-2
Published Date: 13/12/2017

Companies have taken numerous initiatives to better integrate natural and social capital assets into their business planning (e.g. treatment wetlands, payments for ecosystem services, and encouraging pro-environmental behaviours). An Accounting Tool, accompanying guidance document, and project report with two case studies have been developed to support such initiatives. The Tool helps focus on the long-term management of assets and facilitates better investment cases for options that enhance natural and social capital. The Tool produces two outputs: a balance sheet (showing the value of assets and maintenance cost liabilities) and an appraisal summary table (costs and benefits of individual options). The structure and transparency of the Tool respond to the expectations of the (economic and environmental) regulators for more systematic approaches to manage natural and social capital. While for PR19, application could be for pilots, further versions of the Tool can be an integral part of the preparation for PR24.
