Bring Your Own Emission Factors (BYOEF) allows you to upload your own emission factors to the Plan A Sustainability Platform for use in emissions calculations. You can combine these emission factors with activity data to calculate your emissions.
There are various reasons why you may choose to do this. For example, if your organisation has developed or hired a consultant to create custom emission factors based on industry-specific methodologies, you can use this feature to ensure your calculations reflect these factors.
Similarly, you may want to use emission factors taken from external databases or suppliers. In some cases supplier-specific emission factors can offer more precise emissions calculations, enabling a more accurate representation of your company’s environmental impact.
Plan A does not test or verify any emission factors you upload. It is your responsibility to ensure that the factors align with your reporting requirements and regulatory standards. To ensure accurate emissions calculations, please check that emission factors from different suppliers are not double-counted. Additionally, verify that emissions are correctly allocated in line with the GHG Protocol guidelines. We recommend maintaining proper documentation of your methodologies and sources to support data transparency and auditability.
