Greenhouse Gas Emission

Southern Clams Limited has been voluntarily reporting their carbon emissions since 2010 in accordance with the international standard for GHG accounting ISO 14064-1. This report relies on the values and figures provided by staff at Southern Clams and no attempts are made to verify the data. This report is not intended to replace programmes such as the Carbon Zero Programme.

Southern Clams purchases Permanent Forest Sink Initiative (PFSI) credits to offset their carbon emissions. The PFSI is a sustainable forest programme that allows land owners to receive carbon credits through the creation of permanent forests[1]. Southern Clams purchased 1,460 credits and currently has a net surplus that will be used for future offsetting. To view the retired credits click here.
