While there are many self-assessment tools available, we have decided that the best way to ensure an accurate and comprehensive calculation of our annual carbon emissions is to employ experts in the field. We retain the services of GreenStep, who calculate our footprint based upon global recognized standards of assessment.Once GreenStep's team has provided us with our annual carbon emissions, we multiply that figure by 2 and purchase high-value carbon credits to compensate for our footprint twice-over.
