Carbon Emissions Calculators
These tools are provided by Zero Waste Scotland to support organisations to assess the carbon impact of their activities beyond what is traditionally captured in a carbon footprint.
Known as ‘Scope 3’ emissions in carbon accounting, organisations who want to be truly ’net zero’ will need to account for and take steps to reduce as much of their carbon impact as is possible. These tools will help you do that.
Calculate your office equipment emissions
Everything your organisation purchases has a carbon impact. This tool will allow you to calculate the carbon emissions associated with common office equipment purchases.

Contractor emission calculator
Work carried out by contractors on your behalf has a carbon impact. This tool will allow you to calculate the carbon emissions associated with work carried out by office-based contractors (e.g. consultants).

Calculate commuter emissions
Staff commuting emissions aren’t traditionally included in an organisation’s carbon footprint, but when assessed are often found to have a very significant impact. This tool includes a staff survey of travel habits, and a calculator to quantify the carbon impacts of staff commuting.
