How does Clif Bar calculate its carbon footprint?

Clif Bar completes an annual inventory of our company-wide greenhouse gas emissions in accordance with the GHG Protocol. All operational and supply chain data is collected at the beginning of the inventory process, reviewed internally, and calculated into GHG emissions using emission factors. Clif Bar then undergoes a verification audit by an independent third-party to provide assurance that Clif Bar’s GHG emissions inventory is in conformance with applicable standards.
