In 2025, TUI, along with global aviation giants Jet2, Delta Air Lines, Vietjet, and the Lufthansa Group, has made significant strides in sustainability, revolutionizing how tourism and aviation intersect in an eco-friendly world. These companies are setting ambitious goals, from reducing their environmental footprint to pioneering Sustainable Aviation Fuel (SAF) adoption, next-generation aircraft, and radical operational efficiencies. With sustainability in aviation now a pressing priority, these companies are contributing to a shift that could forever change the tourism and aviation sectors.

Why is Sustainability Important for TUI and the Aviation Industry?

Sustainability has become a fundamental principle in tourism and aviation, industries known for their carbon footprint. As global environmental awareness grows, companies like TUI and global airlines such as Jet2, Delta, Vietjet, and Lufthansa have worked tirelessly to reduce emissions, conserve resources, and foster positive social and economic development worldwide. These actions aim to meet the United Nations Sustainable Development Goals and ensure that tourism and aviation remain forces for good.

These achievements come at a pivotal moment in the global sustainability transition. Reports from AirlineRatings.com, Fast Company, and other bodies show that aviation is making critical strides in the transition to sustainable energy, pushing beyond early-stage pilot projects and into full-fledged implementation of green technologies. The actions taken by companies like Jet2, Delta, and others mark a tangible shift in the aviation industry toward a greener future.

What Are the Key Sustainability Milestones Achieved in 2025 by TUI and Other Airlines?

Jet2’s Fleet Modernization and Environmental Excellence

In 2025, Jet2.com emerged as a global sustainability leader, winning the “Package Holiday/Leisure Airline” award at the AirlineRatings.com 2025 Sustainability Awards for its work in aircraft efficiency, environmentally responsible operations, and eco-friendly resort initiatives. Key actions taken by Jet2 in 2025 include:

Delta’s Operational Innovation and SAF Expansion

Delta Air Lines reached remarkable sustainability achievements in 2025, focusing on operational efficiency and sustainable aviation fuel (SAF) usage. Highlights include:

Vietjet: Low-Cost Sustainability Pioneer

Vietjet has taken significant steps in sustainability in the Asia-Pacific region, earning recognition as a 2025 Sustainability Award winner. Key achievements include:

Lufthansa Group’s Technological Solutions for Sustainability

The Lufthansa Group focused on cutting-edge technological solutions to reduce carbon emissions in 2025. Among their major initiatives:

How Are These Airlines Contributing to Sustainable Aviation Fuel (SAF) Usage?

Sustainable Aviation Fuel (SAF) continues to be a major area of focus for global airlines in 2025. However, the global supply of SAF still lags behind demand, with some airlines making significant strides despite challenges.

SAF Usage in 2025:

What Are the Industry-Wide Challenges for SAF?

Despite the positive trends in SAF adoption, the aviation industry is still grappling with several challenges:

• Global SAF supply remains low, with industry projections still below the 1% target for total jet fuel consumption.
• Airlines like Delta and United are advancing SAF usage at individual hubs, but global integration remains slow due to the high cost and limited production.

However, Airbus’s “ZEROe” hydrogen aircraft program is seen as the future, as it moves towards fuel-cell technology to replace traditional combustion methods by 2040. Despite a 10-year delay in the entry into service timeline, the company’s success in hydrogen-powered aircraft testing brings hope for a sustainable future in aviation.

Conclusion:

The 2025 sustainability milestones achieved by TUI and major airlines like Jet2, Delta, Vietjet, and Lufthansa signal a promising future for the aviation and tourism industries. These companies are leading the way with innovative sustainability solutions, including SAF adoption, fleet modernization, and operational efficiencies. However, challenges remain, particularly with the supply of SAF and the infrastructure needed for hydrogen-powered aircraft.

As the aviation and tourism sectors continue to innovate, these airlines’ progress provides hope for a greener, more sustainable future, where aviation and tourism can thrive while significantly reducing environmental impacts.
