CarbonTrail + Xero

Getting started with CarbonTrail is easy - and fast! Most of our clients are up and running in under an hour of connecting.

How it works:

  1. Connect to your Xero Account (using the Get this app button above). After a few quick questions, CarbonTrail then looks at your business spend data and applies emissions factors from a range of quality NZ sources to calculate your carbon footprint (scope 1, 2 and 3). By taking action and connecting your data you can use our badge to promote your carbon reduction ambitions.

  2. Measure and reduce your impact Baseline your carbon emissions and report on how business purchasing decisions affect carbon emissions. Set your own targets, or work with our partner Sustainability Consultants to achieve a recognised Carbon Certification such as Carbon Neutral ISO16064 or as part of your B-Corp application.

  3. Offset unavoidable emissions Some of your emissions will be unavoidable, and for those we allow easy 1-click offsetting through a partnership with CarbonZ. You'll get a certificate evidencing your carbon credits using their Aotearoa New Zealand native forest projects.

  4. Improve your accuracy CarbonTrail's sophisticated AI can calculate your emissions, but we're continually working on how we incorporate more of the precise data that's personalised for your organisation. Business can also connect with their suppliers, for accurate end-to-end tracking of hard to measure Scope 3 emissions.

Easy prep for Certification

Carbon Trail is taking the complexity and cost out of the next step for us, which is Carbon Neutral certification with Toitu - keep up the good work Tom and team
