Net Zero Action Plan performance reports and 2024/25 summary

Net Zero Action Plan (NZAP) Year 1 to 6

Net Zero Action Plan (NZAP) Year 6 - 2024/25

The Net Zero Action Plan Performance Report charts the planned activities of the council in reducing our organisational emissions. Overall emissions have reduced by 55 per cent from the baseline year (2018/19) with emissions having consistently decreased. During 2023/24 and part of 2024/25 up until December 2024, the council operated two Civic Centres, Stockwell Close and Churchill Court, concurrently while transitioning operations from one site to the other, resulting in a slight increase in year 5. For the current reporting year there was a 13.5 per cent reduction in emissions from year 5 (2023/24) to year 6 (2024/25).

The emissions are measured in carbon dioxide equivalent (CO2e) and from sources under the council’s direct control (scope 1 and 2).

For 2024/25, this includes:

Buildings - 62 per cent of overall emission (2,020.0 tCO2e) (includes gas and electricity consumption).
Street lighting – 32.8 per cent of overall emissions (1,068.2 tCO2e)
Business travel - 4.6 per cent of overall emissions (148.6 tCO2e)
Paper - 0.3 per cent of overall emissions (11.8 tCO2e)
The council’s Fleet - 0.2 per cent of overall emissions (7.4 tCO2e)
Water usage - 0.1 per cent of overall emissions (4.0 tCO2e)
Waste - 0.03 per cent of overall emissions (0.9 tCO2e)

For the NZAP, these are the summary updates made on the 7 priority initiatives:

Initiative 1: Street lighting LED upgrades
The majority of Bromley’s 28,000 streetlights were upgraded prior to this reporting year. 422 LED streetlights were converted in the finance year 2024/25 (year 6).
Initiative 2: Buildings (energy efficiency)
To realise future cost/energy/carbon savings the council is progressing energy efficiency improvements of the estate and moving towards the use of low carbon energy sources for heating if feasible and within budgetary requirements.
Initiative 3: 100 per cent renewable energy
New energy contracts commenced on 1st October 2025 with EDF for electricity (including bundled REGO’s) for two years on a fixed rate and gas for three years on a fixed rate. The new contract and timing to commence in October 2025 meant that a 22 per cent cost saving was achieved.
Initiative 4: Zero Emission Fleet
We have also seen a 72 per cent reduction in emissions from our own owned fleet from the year 1 baseline. The fleet consists of 34 vehicles, which includes 5 electric vehicles which accounts for just under 15 per cent of the fleet. However, there are also currently 10 hybrids and hence in total just over 40 per cent of our owned fleet is either electric or hybrid.
Initiative 5: Alternative Technologies and Renewables Investment
We will continue to explore opportunities for renewables as and when they materialise.
Initiative 6: Woodlands, parks and greenspaces
From 2021 to 2025, the council planted 5000 trees over a 4-year period as part of the Treemendous programme, with 1585 trees planted during the 2024/25 planting season. With funding from the Local Authority Treescapes Fund (LATF), the council has planted five micro forests, each approximately 200 m² in size and containing around 600 trees. Tree Friends are volunteers that help the council's tree team maintain a healthy tree stock across the borough.
Initiative 7: Certified Carbon Offsets
The Carbon Management Team will explore opportunities for the most appropriate and cost-effective carbon offsetting credits further into this plan, once all of the above initiatives have been fully appraised.

The Greenhouse Gas (GHG) Accounting Tool developed by Local Partnerships, working with the Local Government Association, is used to calculate the council’s emissions.
