  • The ACE Calculator is a good option if you are just starting your carbon journey, or if you want to use your carbon footprint for internal purposes. It supports the measurement of fuel related to Scope 1 and 2 emissions, refrigerant gas fugitive emissions and common Scope 3 emissions such as business travel, waste and working from home.

    If you require an ISO compliant carbon measurement and need to disclose your carbon footprint to stakeholders, please contact us for guidance, as the Tadpole ACE Calculator may not fully meet your needs. For example, for manufacturers and retailers, there may be emissions in the supply chain that the Tadpole ACE Calculator does not measure.
