Improve Your Measurement
A calculator estimate is a starting point, not an organizational inventory. TerraCO's advisory scope covers greenhouse-gas measurement designed around your operations and boundaries.
Carbon Calculator
Understand Your Carbon Footprint
Estimate the greenhouse-gas volume you want to address using the TerraCO Carbon Calculator and identify areas where measurement, reduction and climate action may be appropriate.
Step 1 of 3
What would you like to measure?
Select one category, or combine categories into a single estimated footprint.
Calculator results are estimates based on the information provided and the applicable calculation methodology and emission factors. They should not automatically be treated as a verified organizational greenhouse-gas inventory or an assurance statement.
Estimates follow the structure Activity Data × Applicable Emission Factor = Estimated GHG Emissions, normalized to kg CO₂e and tCO₂e. Only published factors with a recorded source, geography, version and review date are applied.
No result here states that you need to purchase a given number of carbon credits. Pricing, inventory and availability remain unavailable until eligible credits are documented and approved.
Already know your emissions?
Enter your estimated emissions in tCO₂e
If your emissions are already measured, you can skip the activity questions and frame a volume directly.
How much carbon would you like to address?
One eligible carbon credit generally represents one metric tonne of CO₂e under its applicable program. No claim is made here for projects without issued credits.

Next Steps
Three ways to act on an estimate
Measurement, reduction and carbon-credit procurement work together. An estimate alone does not determine the right course of action.
Develop a Reduction Strategy
Understanding a volume is only useful alongside a plan to reduce it. TerraCO can work with organizations on reduction priorities and pathways before considering carbon credits.
Explore Carbon Credits
Where carbon credits are appropriate as part of a broader climate strategy, the marketplace shows project records, their status and the request pathways available.
