## Definition and Operating Context

Lifecycle emissions measure greenhouse-gas impacts across defined stages of a fuel or product's production, distribution and use rather than considering combustion alone.

Aviation Glossary

**Term:** Lifecycle Emissions

**Category:** Sustainable Aviation

## How the Term Is Used

Lifecycle Emissions is used in aviation emissions accounting, fuel procurement, environmental regulation or operational planning. The applicable boundary, accounting method and claim basis must be stated clearly.

## Commercial and Reporting Effect

For sustainable aviation fuel, lifecycle methodology determines the emissions reduction attributed to a pathway.

## Claim and Compliance Controls

Environmental claims should identify the underlying methodology, reporting period, registry or regulatory framework and controls against double counting. Physical fuel use, contractual attributes and regulatory compliance are not always the same thing.

Frequently Asked Questions

## Lifecycle Emissions FAQ

What does Lifecycle Emissions mean in aviation?

Lifecycle emissions measure greenhouse-gas impacts across defined stages of a fuel or product's production, distribution and use rather than considering combustion alone.

Why does Lifecycle Emissions matter?

For sustainable aviation fuel, lifecycle methodology determines the emissions reduction attributed to a pathway.

Where would an aviation professional encounter Lifecycle Emissions?

It is commonly encountered in sustainable aviation documents, procedures, calculations or operating discussions where the underlying technical or commercial issue is relevant.

Is the environmental claim the same as a regulatory compliance obligation?

Not necessarily. Voluntary claims, contractual fuel attributes and mandatory regulatory obligations can use different accounting boundaries and eligibility rules.
