Tennent Brown Carbon Footprint

17.07.19

The total emissions for Tennent Brown in the financial year of 2018-19 was 24.66 tCO2e. If it takes 5 trees to ensure that at least one lives to 40 years or that their combined sequestration equals one tonne (www.carbonify.com), we need to plant 124 trees to account for our emissions for that year. Tennent Brown will help the Manawa Karioi Ecological Restoration Project by planting 200 trees in Island Bay.

45% of our emissions came from domestic flights, 36% from road use including staff commuting, 10% from electricity, 8% from waste and 1% from materials.

For 2018-19 we had 21 staff. Overall Tennent Brown total tCO2e emissions per staff member has decreased by 0.52 tonnes over the last five financial years.

The Catalyst ACE Carbon Calculator version 2015 was used to calculate financial years 2014-15 and 2015-16, and version 2017 was used to calculate financial years 2016-17, 2017-18 and 2018-19.
