Terms & Conditions


Our Hybrid Working Calculator collects input relating to a customer’s commuting and/or home working energy use. The calculator produces a report that combines the two calculations (if applicable) and presents a total annual emissions score to the user along with cost and energy saving examples. The individual scoring for home working and commuting is locked until a user/organisation wishes to upgrade to the business version. The report contains information about how a user/organisation can do this. 

How it works


The commuting section of the calculator is underpinned by the Greenhouse Gas Protocol calculations, here:

We use the latest emissions factors for transport obtained from the GOV.UK website, which can be found here:

All calculations are a best estimate and we review calculations and emissions factors on a regular basis. All calculations are based on UK settings.

Home working

The home working section of the calculator is based on the the open source white paper produced by Ecoact,

The paper outlines a strategy for base case and enhanced calculations, our calculator uses the latter and extends it further. All calculations are a best estimate and we review calculations and emissions factors on a regular basis. All calculations are based on UK settings.


Both home working and commuting emissions sit within the GHG Scope 3.7 category (Employee Teleworking). The purpose of the calculator is to obtain an enhanced calculation that can help a business baseline, which can then be used to report and/or reduce emissions. The free version of the calculator does not provide the detailed level of information required for reporting. To access the scope data, the user/organisation must purchase the business version of the calculator.

Appropriate use  

The calculator provides an approximation of the carbon emissions related to energy use from home working and commuting. This tool is an indicator for the level of operational energy savings/emissions reductions that could be gained by making changes to commuting or home working patterns.
