GHG Emissions Report 2025-2026 overall emissions

Company name

Hampshire County Council is a local authority whose headquarters are based at:

The Castle
Winchester
Hampshire
SO23 8ZB

Reporting period

1 April 2025 to 31 March 2026

Change in Emissions

The County Council’s overall gross emissions have decreased by 12% this year compared to 2024-25, to 41,712 tonnes of CO2e.

Scope 1 emissions have decreased by 9% compared to 2024-25. Fleet and pool car emissions have increased slightly by 5%. Emissions from heating fuels for buildings has decreased by 10%. Warmer weather contributed to reduced heating demand, with weather conditions resulting in approximately 15% less heating being required compared with 2024/25.

Natural gas remains the primary heating fuel across the estate, and consumption decreased by 11% during the reporting year. Aside from warmer weather, this reduction is also attributed to estate changes, the delivery of energy efficiency measures, and positive behavioural changes implemented across the organisation.

Scope 2 emissions from electricity use in HCC buildings and street lighting have decreased by 20% from 2024-25, this is in part due to the national electricity conversion factor decreasing by 15% from 2024-25 reflecting the greening of the grid. Street lighting consumption has reduced by 12% due to dimming and part-night lighting changes implemented in 2025.

Electricity consumption in HCC buildings has decreased by 5% overall attributable to the same factors affecting gas consumption noted above.

Total Scope 3 emissions, limited to those that we report on, have decreased by 9% from 2024-25. Business travel private mileage decreased by 9% however business travel public transport emissions increased by 8%, this could reflect greater use of public transport in favour of private vehicles for business travel journeys along with the increase in fleet vehicle usage this year.

Water consumption across the estate has decreased by 9% but as the national water conversion factor has increased by 25% it has resulted in a 19% increase to water supply emissions overall.

Approach

We have followed the Government’s Guidance on how to measure and report greenhouse gas emissions along with the Greenhouse Gas Protocol. We used the 2025 conversion factors to calculate the figures.

Organisational boundary

We have used the Financial Control model as the basis to calculate our emissions.

Operational scopes

We have measured our Scope 1, 2 and limited Scope 3 emissions.

Geographic breakdown

The figures relate to UK emissions only. Hampshire County Council have no business interests outside of the UK.

Base year

Following changes in the data collection process, our emissions figures were restated and therefore 2013-14 is taken as the baseline year. In 2021-22 we expanded our Scope 3 reporting to include commercial waste generated by HCC operations and business travel by public transport.

Targets

Following the declaration of a Climate Emergency in July 2019 a target has been set to be carbon neutral by 2050.

Intensity measurement

The intensity measurement is tonnes of CO2e per GIA m2 of the estate as this is the most appropriate way to measure the intensity for the public sector.

This has decreased by 12% to 0.029 tonnes of CO2e per m² of the estate from 2024-25 to 2025-26.

Carbon offsets

The County Council do not currently purchase carbon offsets.

Green tariffs

The County Council did not purchase a Renewable Energy Guarantee of Origin (REGO) electricity tariff during this reporting period.
