# Enabling the carbon emissions tracking

You can start collecting data about the carbon footprint your company accumulates by enabling the carbon emissions tracking option in Payhawk. As a result, the Payhawk accountants and administrators will be able to [export the carbon emissions report on demand](/help/exporting-expenses-and-payments-on-demand) for any given period.

To provide accurate information about the carbon emissions associated with your company card spend, Payhawk partners with [Lune](https://lune.co/). Lune is a leading environmental data analytics company, which provides CO2 estimates that are calculated based on [The Greenhouse Gas Protocol (GHG Protocol)](https://ghgprotocol.org/).

For more information on tracking environmental, social, and corporate governance (ESG) data from suppliers and from your global company spend, see the articles about [configuring additional supplier fields](/help/overview-of-supplier-fields) and [custom expense fields at Payhawk](/help/managing-custom-fields-and-values-from-the-fields-library).

## Benefits

- Fill the gaps in supporting your environmental, social, and corporate governance initiatives with Payhawk Green by gathering the right data for scope 3 emissions around spend.
- Identify areas for improvement in your supply chain by tagging suppliers based on your sustainability criteria.
- Prepare for climate regulations with automatic carbon footprint estimates on all card transactions, which are calculated based on leading international guidelines.

## Specifics

- The carbon emissions report is only visible in the **On-demand export** dialog if it has been first [enabled from the **Settings**](/help/exporting-expenses-and-payments-on-demand) [app](/help/enabling-the-carbon-emissions-tracking#h_deafe4d546).
- The carbon emissions report doesn't show historical data, meaning that it will generate data from the moment of the report enablement onwards.
- By default, the carbon emissions report includes carbon emissions associated with card transactions and lists that data per card expense.
- You can customize your carbon emissions report and [collect supplier data related to ESG](/help/overview-of-supplier-fields) or [collect ESG data on all company spend](/help/managing-custom-fields-and-values-from-the-fields-library).
