Back at the beginning of the century we were more actively engaged in researching the demand side. Most in the industry now accept that the sustainability of the product, and the degree of responsibility exercised by those providing the package or the different elements of the holiday or trip, influences consumer choice.

TUI has concluded, in its 2016 Better Holidays, Better World Report, published in March 2017, that more sustainable holidays are moving into the mainstream. 

• TUI Customers in the past year have gone on 6.3 million ‘greener and fairer’ holidays, i.e. staying in 1170 hotels that have been certified to a recognised Global Sustainable Tourism Council standard.
• In 2016, TUI funding raised for research initiatives, charity, and destination projects reached €6.6 million, and TUI Care Foundation has launched as a group-wide means for supporting destination initiatives.In 2016 our Customers participated in 846 000 TUI Collection excursions, up 30% on 2015.  These are local and unique excursions selected against sustainability criteria.
• In addition, the hard data Customer research that we conducted globally, with over 3000 participants, confirmed that sustainability can be a deciding factor in their holiday choices but that customers want more information when it comes to booking.

There is a discussion of the emergence of Responsible Tourism in the UK in Taking Responsibility for Tourism (Goodwin H 2011)

It is not surprising that a good hotel, an affordable price and good weather (this was a survey of British holidaymakers) were of the highest importance. However, the surprise was that the provision of good local information, a significant opportunity for interaction with local people and a trip was designed to cause limited environmental damage, were all rated as more important than whether the respondent had travelled with the company before. This group of holidaymakers is particularly important to a tour operator since the recruitment cost is low. Moreover, less than 5% of respondents reported in each case that these issues were of no importance to them.

A majority of consumers felt that it was the industry’s responsibility to provide them with more information about the people and places they were going to visit. Clearly, they saw the local people and their place as part of the experience they were purchasing. Perhaps most remarkably, 61% responded that it was important to them that the company had ‘ethical policies’; 27% of the sample said that it was of high importance to them. This was commercially sensitive market research: the point was not lost on the operators.

It may be objected that this market research measures and reports aspiration – upon which the respondents may not act. However, aspiration is a major element in most purchases. Most decisions about travel and the purchase of travel services are based on motivation (activity, destination or experience), opportunity (a function of available leisure time and cost) and a range of other factors which will include quality, safety, experience of and confidence in the provider and what might broadly be considered as ethical considerations. These are evident in the Tearfund research. The primary factors are motivation and opportunity, but, given the range of providers offering similar products at similar prices, the tie-breaker may be one of the ethical considerations, and particularly if these affect the quality and depth of the tourist experience." (Goodwin H 2011 pp58-59)

"The Tearfund/Ipsos-RSL research, in 1999 included the question ‘Would you be more likely to book a holiday with a company if they had a written code to guarantee good working conditions, protect the environment and support local charities in destinations?’ – 45% said yes, 13% said no and 42% said that it would make no difference. In 2001, the research was repeated, with the identical question asked by the same company, to a similar sample – 52% replied positively, an increase of 7% in two years.60 The research has not been repeated because it has become unnecessary."  (Goodwin H 2011 pp61-62)

There is little recent published research because it is now broadly accepted in the UK industry that sustainability is, for a significant majority of travellers, assumed; and that the industry must respond.

There is also a paucity of comparative research on the importance of sustainability in different source markets. The Canadian Tourism Commission undertook a major study of their source markets published in 1999.

"Research conducted by the Canadian Tourism Commission included for the first time in 2009 a standard question in large surveys of its 10 major source markets. They asked whether or not the interviewee agreed with the statement “I always take environmentally friendly tourism considerations into account when making a decision about where to travel to”. Accepting that this only records self-ascribed aspiration there are significant differences between representative samples in Canadian source markets – 88% of Mexicans, 68% of Chinese, 60% of Koreans and 56% of the French ascribe to this view of their decision making about holidays, compared with 33% of the Germans and Japanese, 31% of Americans, 30% of Canadians and 28% of Australians. The British came bottom: only 23% responded that they always take environmentally friendly characteristics into account when making destination choices. Responsible Tourism has been successful in the originating market which, amongst these eight markets, is the least predisposed to choose environmentally friendly options. Many will be tempted to dismiss the British experience as unrepresentative, but on the Canadian evidence, there are originating markets which look significantly more propitious for this approach.

A survey by Booking.com of a minimum of 1,000 respondents who had travelled in 2016, and planned to travel in 2017, in each of 11 source markets reported that

• 68% confirm they are more likely to consider choosing an accommodation knowing that it was eco-friendly, with Chinese (93%), Brazilian (83%) and Spanish (80%) travellers the most likely. For a large 79%, sustainable considerations also impact their mode of transport when travelling, with 43% taking public transport whenever possible, 42% trying to walk, bike or hike as much as possible and nearly one-fifth (18%) flying less to reduce their carbon footprint. 64% said they would pay more for local food in their hotels, and 68% said that they were more likely to consider accommodation if it’s eco-friendly
• 94% were willing to stay in a luxury property with energy saving light bulbs, 89% in one with AC/Heating units that only run while you’re in the room and 80% in one with low flow showerheads. Luxury adjustments that they said they were willing to make to sat somewhere eco-friendly:
  • energy saving light bulbs 95%
  • AC/Heating units that only run while you are in the room 89%
  • low flow shower heads 80%
  • recycled toilet paper 79%
  • less frequent toiletry replacement  79%
  • linen and towel changes less frequently 75%
  • higher costs fo locally produced food 64%
• The reasons given for choosing eco-friendly accommodations included helping to reduce environmental impact (52%); providing  a more locally relevant experience (36%) and "they treat the local community better" (31%)
