Hamburg, Germany ─ The GBTA Foundation, the cause-led arm of the Global Business Travel Association (GBTA), today released the second-year findings from its Sustainability Acceleration Challenge, a global benchmark assessing the state of corporate action to decarbonize business travel programs.
Input from 285 companies across the globe – representing an annual business travel spend of $22 billion USD – reveals that companies are still committed to tracking and managing carbon emissions from their employee travel programs, with measurable gains in maturity and more organizations joining the effort. Progress, however, remains limited in certain high impact areas, underscoring the need for faster, collective action to invest in low-carbon travel solutions.
Year two of our benchmark shows real engagement and growing commitment. But despite progress, greater urgency is needed. To future-proof business travel, companies must accelerate adoption of sustainable procurement practices and carbon management strategies to send a real signal to the market. Delphine Millot, Senior Vice President, Advocacy and Sustainability, GBTA, and Managing Director, GBTA Foundation
The 2025 results from the global benchmark developed in collaboration with Accenture were released today at the GBTA + VDR Europe Conference in Hamburg and can be downloaded here.

Key findings from the 2025 GBTA Sustainability Acceleration Challenge include:
- Participation continues to grow: 285 companies participated in the 2025 assessment, marking a 20% increase compared to 2024. Across the two years, participants represent approximately $31 billion in annual business travel spend and include one-quarter of BTN’s Top 100 corporate travel programs.
- Incremental maturity gains: The global average score is now 1.4 compared to 1.3 in 2024 (out of a maturity scale from 0 showing “no activity” to 5 being “leading practice”), reflecting limited overall improvement.
- Regional shifts: Global and APAC travel programs improved slightly, while regional and local programs in Europe and North America dipped marginally, likely due to regulatory changes and economic uncertainty.
- Program size correlation: Smaller ($500M) programs have regressed overall, perhaps demonstrating that while companies under intense public scrutiny may be slowing their sustainability efforts, smaller companies may be using sustainability leadership as a way to differentiate themselves.
- Leading industry sectors: The Financial, Banking and Insurance sector continues to lead (maturity score of 1.9 out of 5), followed by the Professional Services and Consulting sector (score of 1.7). These sectors traditionally have a large share of their emissions coming from their business travel programs.
Where companies are making progress:
- Cost-positive sustainable practices are accelerating. Sustainable Travel Policies (2.2 score in 2025 versus 1.8 score in 2024) and Carbon Budgets (0.7 score in 2025 versus 0.5 score in 2024) show strong year-over-year improvement.
- Reporting and targets setting are becoming standard. Reporting (2.7 score in 2025 versus 2.1 score in 2024) and Targets Setting (1.7 score in 2025 versus 1.4 score in 2024) are increasingly built into travel programs – although the largest companies show some regression.
Where acceleration is urgently needed:
- Shaping travel decisions. Tools that influence booking choices – Carbon Fees (score of 0.4 in 2025) and OBT (online booking tool) Features (score of 2.4 in 2025), have stalled. Embedding these mechanisms is key to enforcing sustainable travel policies.
- Sending a unified demand signal: While supplier sustainability assessments are increasing, advanced levers such as the GBTA Sustainable Procurement Standards and sustainability clauses in Contracting (score of 1.2 in 2025), show no movement – likely hindered by limited guidance and technology enablement.
- Investing in emissions abatement: The use of Sustainable Aviation Fuels (SAF) to decrease emissions from business travel is growing (15% of corporates purchasing SAF certificates in 2025, up from 12% in 2024), but adoption remains low. Corporates can leverage GBTA SAF Corporate Connect for best practices on SAF implementation.
The GBTA Sustainability Acceleration Challenge provides a roadmap for the future. With more companies participating, we’re seeing where the industry is moving forward, and where further collaboration can close the gap between ambition and action.
