Image Booking.com logo for Travel Sustainable Program

As arguably the world’s leading Online Travel Agent, Booking.com has realized that they are in a unique position to be able to make a difference to the troubling statistics associated with tourism and travel. They work with millions of accommodation partners around the world. While they do not own the properties themselves, Booking.com provides information for travellers to find a place to stay.

Booking.com has stated that they believe they share in the responsibility to help the travel industry tackle its emissions. From the Travel Sustainable Reports which they undertake every year, the OTA has established that more needs to be done to make sustainable travel easier – and sustainable accommodation easier to find. Among the travellers who hadn’t stayed in a sustainable accommodation over the past year, 31% said they didn’t know they existed and 29% said they still didn’t know how to find them.

The good news is that demand for sustainable accommodation is growing year on year. The Sustainable Travel Report by Booking.com found that in 2022:

– 71% of global travellers expressed a desire to travel more sustainably over the coming 12 months

– 70% of global travellers say they’d be more likely to choose a sustainable accommodation, regardless of whether they were looking for one or not

– 78% of global travellers intend to stay in a sustainable property at least once in the coming year.

Update: There have been changes to the Travel Sustainable program as from March 2024.

Booking.com began developing the Travel Sustainable program in 2019. Working with sustainability consultancy Sustainalize, (now ERM),  they designed a list of sustainability initiatives which they hoped any type of accommodation could implement that were both impactful and practical.

They spanned five separate categories:

1. Water

2. Waste

3. Greenhouse gas emissions

4. Environmental protection

5. Community support.

This was benchmarked against the attributes already considered by 3rd-party sustainability certifications, like those of the Global Sustainable Tourism Council (GSTC), Green Key and EU Ecolabel, which is considered to be the gold standard in the travel industry.

In November 2022, Booking.com launched new levels for their Travel Sustainable badge. Each level built on the next, starting at a basic level of sustainability implementation all the way up to 3rd-party certified, which they saw as crucial in both encouraging partners to continue on their pathways and recognising the outstanding commitment and investment of those partners who had achieved one of more than 40 certifications or ecolabels.

The Travel Sustainable Levels were designed to better recognize and support the efforts and investments on a property’s sustainability journey – whatever stage they may be at.

While all eligible partners received the same badge, Booking.com recognized each eligible partner’s sustainability efforts at one of three different levels, or, for those with eligible third-party certification, at a dedicated level.

What is the Booking.com Level 1?  

The property has implemented some impactful sustainability practices

What is the Booking.com Level 2?

The property has made considerable investments and efforts to implement impactful sustainability practices

What is the Booking.com Level Travel Sustainable Program?

The property has made large investments and efforts to implement impactful sustainability practices

Level 3+ Certified

The property has made a strong commitment to sustainability by subscribing to one or more third-party certifications and making a significant difference in the reduction of their environmental impact.

When Booking.com launched Travel Sustainable in 2021, there were less than a hundred thousand recognised properties. Now, more than 1.25 million accommodations globally have now shared at least some information about their sustainability practices. 

This alone has brought attention to accommodation owners around the world that working towards sustainability is a worthwhile journey.

However, with the realization that many companies (not just accommodation) have been involved in greenwashing, Booking.com has made changes to the program as from March 2024 to only allow properties to display a sustainability icon if they have 3rd party certification.

How to take the First Steps towards Sustainability in Tourism

For some accommodation owners, the idea of moving towards sustainability can seem a bit overwhelming at first, but the good news is that there are plenty of easy first practical steps you can take to make your accommodation more environmentally friendly.

Working Towards Sustainable Tourism Accommodation: First Steps

If you intend to take responsible tourism seriously, start with these few first steps…

Green Hospitality Resources – what to look for

Hotel Amenities – What you need to know

What denotes luxury to you when it comes to hospitality amenities? For international hotels, the meaning is changing…

Why do we need to change the way we travel?

 While travel is one of the best things about life, it has proved to have unfortunate, negative consequences for the environment. The rise of mass tourism and cheap flights in the 1970s has given rise to overtourism, with once-pristine beach towns being transformed into concrete jungles. Cultural centres such as Venice in Italy have become almost unliveable for its residents, with pollution issues and strain on the local infrastructure.

Things have to change and there is growing concern in the tourism industry about its future. According to a report in Nature, the travel industry accounts for roughly 8% of the world’s total greenhouse gas (GHG) emissions. A third of the emissions related to travel come from the accommodation we stay in – an essential part of every trip.

As the world’s largest accommodation finder, Booking.com has stated that: “By now we all know the consequences of unchecked, unabated emissions. It’s the climate crisis we are all facing, right now. We must act now to preserve a world worth experiencing for everyone.”

” A third of the emissions related to travel come from the accommodation we stay in – an essential part of every trip.”
