Sustainable Business Travel Online Course for Industry Professionals

The GSTC Sustainable Business Travel course provides the knowledge and tools needed to help improve sustainability practices in business travel. The training follows the GSTC Criteria, the global standards for sustainability in travel and tourism, and provides best practices for a business travel program.

Delivered as a 4-week-long facilitated and interactive training class, the sustainable business travel online course offers a convenient way to improve your sustainability skills in a flexible online learning environment, while at the same time learning alongside GSTC experts and fellow sustainable business travel practitioners.

The course will help you achieve tangible actions to follow globally recognized standards of sustainability best practices.


The GSTC program has a rich pedigree, evolving as it has from a United Nations sustainability initiative. This, coupled with an existing history of pursuing sustainability initiatives in tourism and leisure travel, has provided a rich foundation for the corporate travel course. The instructors likewise bring a history of expertise and passion in the area of corporate travel sustainability. This converges into a course that can dramatically impact the role that corporate travel takes in combatting climate change, inequity, and other sustainability shortfalls in the corporate travel industry.

Michael Hall, Senior Manager, Global Travel, llumina

This first GSTC Sustainable Business Travel training course has definitely exceeded my expectations. As the world has changed due to covid, this course provides practical steps for corporates around the globe on how to build a responsible and sustainable corporate travel program to make positive contributions to the destinations. I found the relevant and up-to-date teaching materials, interactive style of training by two industry experts Horst and Bernard, and live breakout sessions where industry participants share ideas and formulae solutions to today’s problems particularly helpful.

Benjamin Wong, Co-founder and CEO, Tricolage

While most often focus within sustainability is around CO2 reduction, however, this course really brings out the other pillars of sustainability (socio-economical, cultural, management). The use of the small group discussions opens up the communication, and allows you truly listen to other views and insights.

Howie Honeycutt, Senior VP, Global Operations and Shared Services, ATG Travel

I decided to attend the course to better understand the post-pandemic scenario in the business travel industry. The course was far beyond my expectations, it has been a great occasion for networking with professionals from all over the world but most of all I must say that the knowledge and inputs shared by the GSTC trainers will surely be of great help to improve not only my professional skills but also to engage colleagues in exploring the sustainable and responsible best practices for the industry.

Enrico Presicci, Event Manager, Indigenus Experiences

This is the definitive go-to guide for sustainable business travel and was incredible opportunity to learn about the future of travel at a global scale.

Daniel Nettuno, Consulting Engagement Manager, American Express Global Business Travel

The enthusiasm of the trainers – Horst and Bernard – made a difference. The course was one of the best learning experiences I had in my career.

Sesilia Kalss, Senior Consulting Manager, American Express Global Business Travel

If you ever want to expand your knowledge or organize your existing knowledge in the field of sustainability, gain a broader perspective on various sustainability topics from every possible angle, exchange experiences and best practices during live sessions in an international environment, get the knowledge from professional mentors, and additionally gain knowledge where to look for valuable content on the Internet concerning current news on sustainable tourism – I wholeheartedly recommend the GSTC Sustainable Business Travel training. There will be a lot of reading, a lot of watching, but the more time you spend working at home during the course the more you will get out of the live classes.

Monika Górnik, Customer Care Manager, Meetings & Incentives, Weco-Travel

The course helped me become much better informed, learning about new reporting criteria, what official institutions there are for certification and how companies can best share their activities and reports. Interaction with other participants was useful, the speakers and presentations were very useful with great tips about books and articles. It definitely increased my awareness that sustainability is not just about the environment but also about people and culture. Taking the exam is a good opportunity to practice what you learn with a real case from your own company or clients.

Marijke Poppink, Owner, Poppink TRVL Projects

The GSTC Sustainable Business Travel course is a great way to get an overall view of the tasks that lie ahead, when turning Business Travel green. Highly recommendable.

Peter Skieller, CEO, Nordic NDC

I am now more aware of what needs to be done within the travel space with applicable knowledge of where to start. The team was very knowledgeable, with prominent speakers and elaborated discussions.

Bindu Dominic, Global Travel Operations Manager, Cisco Systems

This was an eye opening course! I thought I knew what will be taught, but there is much more to sustainability than I expected. The trainers and guest speakers clearly know what they’re doing and the wisdom they can instill is inspiring.

Matt Lewis, Sales Representative, Alta Group

Thank you for the opportunity and privilege to take GSTC Sustainable Business Travel Course. I cannot express how enjoyable I feel the course was and the passion Bernard and Horst feel for the material was contagious. I found the final exam both challenging and invaluable.

Katie Romanko, Travel & Events Sourcing, Dropbox

…I have enjoyed the course very much and look upon it as very educative enriching the knowledge and insights which are currently developing in the global market on this topic. In case there are plans to develop and provide a follow-up course or any other type of follow-up I’m happy to participate again….

Gert van Spijk, Senior Specialist Travel Technology, MSD

The GSTC Business Travel course is very well geared towards the needs of travel managers. The content of the course is very helpful and entertaining. At the end of the course, everyone is able to realistically classify themselves and their company in terms of sustainability.

Albert James Küng, Head of Global Travel Management, Siemens

It was a great course, especially for a tour company like ours that is thinking of expanding to Business Travel. For us, it is important to start working with the pillars of GSTC as a lighthouse. Have the opportunity to share with colleagues from all over the world and enjoy the leadership during the course of two great sustainability professionals and speakers was indeed the best scenario!

Raffaele Di Biase, Co-Founder, BirdsChile
