## At a glance
- SkyTeam alliance comprises 18 member airlines serving 945+ destinations across 145+ countries, with 605 million annual passengers.
- SkyTeam's 60-person Amsterdam office uses 100% renewable energy; primary environmental impact derives from Scope 3 business travel emissions.
- IATA CO2 Connect calculates emissions from mandatory city-pair data plus optional fields: airline, date, passenger count, cabin class.
- Results present CO2 only, tank-to-wake, well-to-wake and CO2 equivalent metrics per flight and for total reporting period.
- SkyTeam plans annual Scope 3 reporting and expects emission reductions once new sustainable travel policy is implemented.

## What the report covers
This IATA Knowledge Hub case study documents how SkyTeam, a 18-carrier global airline alliance, implemented IATA's CO2 Connect for Corporate Travel tool to calculate and report Scope 3 business travel emissions. The report explains the challenge of accurately measuring corporate travel emissions, the platform solution provided, and how SkyTeam will use baseline data to drive a new sustainable travel policy and meet ESG reporting obligations under frameworks including EcoVadis and the UN Global Compact.

## Key findings
SkyTeam operates as one of three major global airline alliances with scale spanning 18 member airlines, 945+ destinations across 145+ countries, 605 million annual passengers, and 13,800+ daily departures. The alliance's Amsterdam management office, co-located at KLM headquarters, employs around 60 staff and uses 100% renewable energy with no fuel-powered vehicles or equipment. Despite this operational sustainability, Scope 3 business travel emissions remain the primary environmental impact.

SkyTeam lacked simple, accurate tools to calculate business travel emissions for single reporting periods, creating a barrier to ESG compliance. The absence of baseline data prevented the alliance from establishing emission reduction targets required by reporting frameworks such as EcoVadis and the United Nations Global Compact.

IATA CO2 Connect for Corporate Travel provides airline-verified CO₂ emissions data through a standardised platform. Mandatory inputs include city-pair information; optional fields accept operating airline, flight date, passenger numbers and cabin class. Results are presented as CO2 only, tank-to-wake, well-to-wake and CO2 equivalent metrics per flight and as reporting-period totals.

Implementation required some manual data entry, though this can be minimised by syncing inputs with SkyTeam's internal travel team datasets. The baseline calculation of total Scope 3 business travel emissions for one reporting year now grounds development of a new sustainable travel policy and identification of emission reduction levers.

SkyTeam commits to annual Scope 3 reporting using the IATA tool as part of ESG obligations. The alliance expects measurable emission reductions once its sustainable travel policy is deployed and aims to establish clear, achievable reduction targets with sufficient historical data.

## Why it matters
**DMOs & destinations** — The case shows how tourism stakeholders can systematically measure and report business travel emissions to meet ESG frameworks. DMOs increasingly partner with airlines and hospitality brands under pressure to demonstrate carbon accountability. Standardised emissions calculation methods enable destinations to align sustainability claims with verifiable data and support corporate clients' net-zero commitments.

**Hotels & hospitality** — Corporate travel decarbonisation is becoming standard in ESG reporting, creating demand shifts from companies implementing restrictive travel policies. SkyTeam's baseline-then-policy approach mirrors strategies likely adopted by major travel buyers. Hospitality operators should prepare for shorter trips, reduced frequency and preference for near-origin destinations as sustainable travel policies deploy globally.

**Travel tech & distribution** — The case demonstrates growing demand for embedded emissions reporting in corporate travel systems. Distribution platforms and booking tools increasingly require standardised carbon data calculation and API integration. Vendors lacking native emissions measurement face competitive disadvantage as corporate procurement mandates carbon tracking capabilities.

## Methodology and limits
This brief is based on a case study published in IATA's Knowledge Hub on 29 May 2026, documenting SkyTeam's real-world implementation of IATA CO2 Connect for Corporate Travel. The source presents observed metrics from SkyTeam's alliance profile and forward-looking statements from its Director of Sustainability regarding future reporting intentions. The report contains no original survey data, statistical modelling, comparative analysis with other carriers, or disclosed actual emissions calculations. This brief reflects only the publicly available summary.
