Turn everyday transactions into climate action.

We calculate the carbon footprint of your purchases using 'emissions factors' that are specific to the category and region of your purchase. The calculation is: Transaction Amount × Category Emissions Factor. For example: If you spend £20 at a supermarket, we multiply this by the emissions factor of groceries in your specific country (e.g. 2.22 kg CO2e/£) to get an estimated carbon footprint of 9 kg of CO2e.

Category-level data: We collect category-level data through Environmentally-Extended Input-Output Analysis (EEIO) using the latest version of the EXIOBASE database. EXIOBASE is one of the most extensive EEIO models available and enables us to track greenhouse gas emissions throughout global supply chains. Corporate emissions data: We collect the latest reports that companies have published, containing emissions data. These may be sustainability reports, ESG reports, CSR reports, and others.

The integration is only API-based. The API integration is easy and accompanied by well-detailed API documentation that makes the process straightforward. Integration typically takes anywhere between 2-6 weeks, depending on the technology and resource capacity of our customers.

We do not store any user data nor do we require access to user data (such as personal information, account details, etc.). We fully comply with banks' and financial institutions' legal and compliance requirements in terms of data security. As a UK-based company following data compliance standards like GDPR and SOC2, we take data privacy and ownership very seriously and are audited yearly for data privacy and security.
