Sustainable development and climate change strategy
Climate change
Climate change presents the single biggest threat to sustainable development and one of the best ways to contribute to lessening future changes in climate is by measuring and understanding our carbon footprint. Once we know where our main emissions come from, we can take measures to reduce them.
The council’s carbon footprint has been measured and reported annually since 2005-06. We have a legislative duty to contribute to national carbon reduction targets which are included in the action plan of the Sustainable Development and Climate Change Strategy.
We measure the gas, electricity, and oil used to heat and power our buildings, the fuel we use to travel, and the electricity used for street lighting. We also measure the emissions that are produced when processing and disposing of the household waste we collect.

There are a number of reasons for this consistent and significant reduction in emissions. Most are related to specific measures undertaken by the council to reduce fuel consumption. However, some changes are a result of updates to the annual carbon conversion factors that are published by the UK Government’s Department for Business, Energy and Industrial Strategy (BEIS). This means that the fluctuating carbon factors over which the council has no control can affect our reported carbon emissions.
The carbon factors fluctuate each year, most noticeably for electricity, as the grid becomes cleaner and greener the carbon associated with generating electricity reduces. Factors for gas, petrol, diesel and oil also fluctuate but not to the same degree. Carbon associated with our waste has also seen significant changes as more is known about the mix of waste collected and what happens when recycling or disposing of it.

Buildings
Many carbon and energy reduction projects have been undertaken since 2005 and have included:
- Voltage Optimisers
- Insulation and Draught Proofing
- Secondary Glazing
- Solar Photovoltaic (PV) Installations
- Combined Heating and Power (CHP) Installations
- LED Lighting
- Water Heater Timers
- Building Energy Management Systems (BEMS) Controls
- Heat Recovery Systems
In addition to these investment projects, an ongoing planned maintenance programme has ensured that our buildings and plant are operating at optimum operation. Asset management plans ensure that assets are reviewed on a regular basis to also ensure services are being delivered from energy efficient properties and projects for new builds and refurbishments ensure building standards are met to a silver sustainability label.

Waste
The following figures and chart show how carbon emissions from household waste disposal have reduced over the years. The reductions are affected by the amount of waste collected but are mainly due to the amount sent for recycling, and more recently sent to the Energy from Waste facility, enabling a much smaller proportion to be sent to landfill.

Street lighting
Many carbon reduction strategies have been employed within our street lighting estate since 2005, most noticeably the ambitious capital-funded LED replacement programme which was completed in 2019 and achieved around a 68% saving in energy consumption. Other interventions have included low-energy pilots, new dimming regimes, and the installation of photocells that adjust the switch on and off times. LED festive lighting and signage which have been replaced on a phased basis have also resulted in reductions over the years. Guidance issued to developers since 2014 has ensured that any new construction sites are installed with LED lighting. Reductions have been achieved despite the number of lights increasing over this term.
The following figures and chart show how carbon emissions from street lighting have reduced over the years.
