Why teams use this for scope 3 category 6

Flight-specific accuracy

Flight specific emissions data based on the exact aircraft, route and distance flown. Most calculators rely only on broad averages.

Best and latest science

Our methodology uses the Google TIM aviation model plus the latest DEFRA radiative forcing factors to estimate CO₂e, including non-CO₂ effects.

Full emissions drill-down

See what your footprint is made of with a breakdown of TTW and WTT emissions.

Calculate flight emissions

At Ecologi, we’re moving away from the term “offsetting.” It’s often used to describe calculating emissions and funding equivalent carbon reductions or removal and leads to incorrect claims that impact has been fully neutralised. That framing not only risks accusations of greenwash but also overlooking the most important step: reducing emissions. That’s why we prefer an approach that emphasises the importance of all 3 steps in the process; measure the impact, do what you can to reduce it and fund action that removes emissions elsewhere. Funding verified climate action is not a substitute for decarbonisation, but a complementary step that supports real, science-aligned progress today.

Why use our calculator?

Business travel often sits within Scope 3 emissions and can represent a significant share of a company’s footprint. For travel-heavy sectors such as consultancy, media, finance, technology and professional services, flights are frequently one of the largest controllable impacts.

Measuring your company's flight emissions with Ecologi allows you to:

Improve Scope 3 reporting and disclosures
Support internal carbon pricing models
Respond to procurement requirements such as PPN 006
Take action on unavoidable residual emissions through verified climate projects

Reducing flights where possible is always the priority. Where travel is necessary, measuring and addressing emissions responsibly is part of credible climate leadership.
