We are a carboNZero Certified Organisation

As a business we take care to keep our energy consumption to a minimum. We are organised and use email, teleconferencing and cloud based file sharing rather than driving or flying where ever possible. Our work output is all electronic and paperless which also means we can work remotely.

The operational control consolidation approach has been used to account for operational emissions with reference to the methodology described in the GHG Protocol and ISO 14064-1:2006 standards.
Our emissions as tonnes of carbon dioxide equivalents (tCO2e) for the 12 month period to 31st March 2013 was 23.57 tCO2e.
