Appendix 4: Key Performance Indicator Framework for the Biodiversity and Climate Change Action Plan

As part of the Biodiversity and Climate Change Action Plan, the Decision-Making Processes and Governance section stipulates Action 9.3 to ‘Ensure service plans consider biodiversity and addressing climate change and performance indicators are set as needed’. The indicators outlined in this framework are for monitoring performance and progress against the Biodiversity and Climate Change Action Plan Actions and not used for target setting as these are data-led projects and subject to best practices, Government guidance, and new technologies which are all constantly changing.

A full public report outlining the progress made against MBC’s net zero target will be published on an annual basis. The key performance indicator for most projects will be the total reduction in tonnes of carbon equivalent per annum (CO2et). Please Note: many of the indicators identified in this document align with National Government and Kent County Council indicators for clear Monitoring, Evaluation and Learning (MEL) comparisons and county wide measurements. Additionally, some indicators listed are out of the Councils direct control and are used to monitor changes in public behaviour, changes in markets, and changing technologies. Other indicators are scientifically based and rely on specialised equipment or knowledge - the monitoring of these indicators are subject to budget availability. Quarterly update reports highlighting particular achievements against work packages will be highlighted to council members. Case studies, best practices and achievements will also be shared with the public by identifying the most appropriate ways to share progress with our communities.

The table of key indicators correspond to specific Actions in the Biodiversity and Climate Change Action Plan, and outlines the indicator, baseline, calculations, data sources and the frequency progress will be monitored.

8.        MBC Procurement reduction in Carbon by suppliers and contracts


Scope 3 includes indirect emissions from wider supply chains (often reaching international jurisdictions), emissions from the use of local authority services, contracted out services and investments. Councils will have a strong influence over some of these emissions (eg contracted out services and investments) and less over others. (See Cheshire East case study in the Procurement & Commissioning section for more details.)

Internal monitoring


Annual Report



[1] Internally the use of the Local Government Association (LGA) Carbon Calculator using monthly gas/electricity readings cannot be completed due to incomplete and manually recorded data records of energy/electricity readings from MBC buildings. Recommended to upgrade all buildings meters to automatic so that data can be collected live. Live automated data would enable much closer analysis of daily energy usage which would help pinpoint inefficient electrical devices and maybe useful in public buildings such as the museum to reduce energy usage at certain times of day when less people are at the museum.
