Emissions monitoring

We worked with the Carbon Trust to calculate its baseline emissions in 2018/19. This is the base we will be working from to reduce our emissions to net-zero by 2030. These reports give greater detail on the breakdown of these emissions.

The table below sets out the Council’s emissions since the baseline year of 2018/19. This table will be updated annually to show our progress in reducing our emissions. We report on our emissions in terms of tonnes of carbon dioxide equivalent (tCO2e). All emissions have varying impacts on climate change (known as their global warming potential), but for simplicity, we equilibrate and report on our emissions in the terms of if they were all CO2 (as this is the predominant emission).

*From financial year 2022/23, electricity consumption was associated with Council buildings, as well as that used in electric and hybrid vehicles.  

During 2020/21, many of our staff moved from mainly working in the office to working from home. We recognised that emissions associated with people working from home would not be captured under normal emissions reporting.

Working from home

During 2020/21, many of our staff moved from mainly working in the office to working from home. We recognised that emissions associated with people working from home would not be captured under normal emissions reporting.

Instead, using a methodology developed by international climate consultancy EcoAct, we estimated emissions created by staff working from home and included these emissions in our reporting.

From 2020/21 onwards, the Council will calculate its emissions associated with staff working from home as this becomes a bigger part of the way that staff work at the Council.

Carbon Management Plan 

We also produce a Carbon Management Plan. The purpose of the Carbon Management Plan is to set out the actions we will take to reduce our emissions, and the specific emission reduction each action will produce. This enables us to stay on track to reach our carbon neutral emissions target by 2030. A new Carbon Management Plan is currently being produced and will be uploaded once it is available.
