Understand and offset your emissions
Use our online carbon calculators to measure your footprint and see where to cut emissions, then offset what you can’t reduce by supporting restorative forests in Aotearoa and the Pacific. Choose the calculator that suits you below.
Business Emissions
Measure your business’s carbon footprint for free and see where to reduce. If your footprint is under 50 tCO2e, you can also offset what remains and apply for Ekos’ Net Zero Carbon Business Lite certification.
Individual Emissions
Estimate your emissions to see where you can cut back, then offset what remains by supporting indigenous forests in Aotearoa and the Pacific Islands. You’ll receive an Ekos Carbon Friendly recognition certificate.
Flight
Estimate emissions associated with your individual air travel.
Lifestyle
Estimate the carbon impact of your lifestyle, including household and travel.
Driving
Estimate emissions associated with your individual car travel.
Household
Estimate your individual household emissions.
How it works
Enter your activity data, such as fuel, electricity, travel and waste, into the calculator that suits you. Use your results to see your biggest sources of emissions and decide what to cut first. Need help with a reduction plan? See our carbon management services. Then offset what remains by supporting restorative forest projects, and receive your Ekos Carbon Friendly recognition certificate or, for eligible small businesses, Net Zero Carbon Business Lite certification.
Where does my offset go?
Ekos carbon credits come from restorative forest carbon projects in Aotearoa and the Pacific. One carbon credit represents one tonne of carbon dioxide taken out of the air by a forest, and each credit is cancelled in a carbon registry so it can’t be used by anyone else. Since 1 April 2026, we donate $1 from every carbon offset to Upstream to help fund youth mental health counselling. See our projects and learn more about Upstream.
Carbon Friendly Recognition
Ekos Carbon Friendly recognition gives you a recognition certificate for offsetting a selected amount of your measured carbon footprint, using conservative estimates and an Ekos-approved estimate methodology.
It is a recognition rather than a certification programme, so no certification mark is included.
-
Your carbon footprint is the total greenhouse gas emissions caused by your activities, measured in tonnes of carbon dioxide equivalent (tCO2e).
-
Voluntary carbon offsetting means taking responsibility for your carbon emissions. We measure the emissions you produce, then compensate for them by causing an equal volume of carbon to be taken out of the air, through establishing new forests and protecting old ones.
-
Estimating your business’s footprint with the business calculator is free. Fees only apply if you choose to offset or apply for certification, and they’re listed on the certification page.
-
Individuals who offset receive an Ekos Carbon Friendly recognition certificate. Businesses can stop with a summary of their footprint, choose Carbon Friendly recognition, or apply for Net Zero Carbon Business Lite certification if they’re eligible.

Medium and large organisations follow our standard certification process. Request a certification quote or contact the Ekos team.
