Download the FREE ACE Carbon Calculator now.

The Annual Carbon Emissions (ACE) calculator, designed by CATALYST R&D Ltd to help businesses and households estimate their greenhouse gas  emissions, as "you cannot manage what you cannot measure".

ACE is a simple to use Excel workbook. Results are displayed by;
- Tables and bar chart of emissions by source each month
- Graph of cumulative annual emissions

Ready to get started?

• Download the ACE calculator-  click here.
• Enter your data on waste and energy use (including road and air transport, electricity, gas) 
• Add refrigerant losses (if applicable) into a separate sheet for each month
• Go to www.greenfleet.org.nz for support with reducing carbon emissions and offsetting.

NOTE: Charts are provided with preset destinations for both air and road transport to help estimate travel distances. Standard, updated emission factors are used to convert energy to emissions. Most emissions factors incorporate non-CO2 gases and hence units are given in terms of CO2 equivalent (CO2e) emissions
