Globally, the world’s travel industry contributes around ten per cent of GNP, but worldwide it is also responsible for about five per cent of CO2 emissions – The majority of greenhouse gas emissions are caused by transport – Climate change is creating eco-awareness but not dampening people’s desire to travel – Travellers want to avoid flying, but are still planning trips abroad – Policymakers are called upon to support research and investment in green transport

According to the United Nations Environment Programme (UNEP), the tourism and travel industry accounts for around ten per cent of global GNP, seven per cent of global exports and more than ten per cent of jobs. The industry is large – and also has a noticeable impact on the environment. Globally, tourism accounts for around 5 per cent of CO2 emissions.

A 2020 eco-awareness survey by the German Environmental Agency found that for 65 per cent of Germans environmental and climate protection is a very important issue. Over 77 per cent of those polled see human activity as being the main cause of climate change. According to the Global Consumer Survey (GCS) by Statista, which worldwide polled up to 60,000 people per country in over 55 countries, climate change has an influence on the travel behaviour of 65 per cent of all tourists in Germany.

Consumers are aware of the transport problem
According to the UNEP, transport is responsible for three-quarters of global CO2 emissions resulting from tourism. Air transport (40 per cent) and car use (32 per cent) account for the majority of these CO2 emissions. Train and bus transport is responsible for only a small share (three per cent). In Germany in 2019 (the base year in order to exclude pandemic effects), a domestic flight with an average passenger load emitted 214 g of greenhouse gases per passenger km – almost 40 per cent more than a car (154 g per passenger km at a load factor of 1.4 persons/car) and almost 638 per cent more than a long-distance train journey (29 g per passenger km).

The current Statista survey now shows that German travellers are indeed aware of the environmental impact of their individual transport. In response to whether they would change their travel behaviour because of climate change, the most frequent answer given was “avoiding (long-haul) flights“.

Climate change has little effect on people’s desire to travel – trips abroad remain in high demand
However, deciding not to travel at all for reasons to do with sustainability is rare. Of the German interviewees planning not to travel in 2022, only six per cent gave protecting the environment as their reason. Accordingly, the threat posed by climate change is not generally affecting people’s desire to travel, but potentially influencing how they go on holiday.

Despite 24 per cent of German travellers interviewed by the GCS saying environmental reasons had recently motivated them to change their foreign travel plans, in 2022 these trips are still in high demand. 70 per cent of Germans planning a trip this year want to (also) cross international borders. Only later will we discover whether people have actually changed their travel behaviour as indicated and actually refrain in numbers from (long-haul) flights and long-distance trips.

Sustainable tour operators are a possible solution
However, in the case of both domestic and foreign trips the following applies: sustainable travel is feasible. A general assessment of package tours, all-inclusive hotels or budget travel is not possible. In addition to the type of transport, there are other aspects which influence how sustainable a trip is and which are of interest to tourists. Thus, for 48 per cent of German travellers avoiding waste is important on their holidays, for example. For 40 per cent, saving resources such as energy and water is important, and 39 per cent would like local staff to be fairly paid. Rika Jean-François, CSR commissioner for ITB Berlin: “Every step towards sustainability counts. Even an all-inclusive resort can be run responsibly and sustainably if it has a proper waste and water management system, uses renewable energy and offers local produce, and if the employees are from the region – however, the management must support these measures. Nowadays, customers no longer have a binary choice between ‘low-cost’ and ’ethically correct’ travel, as more and more operators are including sustainability in their product portfolio without raising prices. This is an investment in the future. Beyond that, independent certification is no less important, as it offers operators and customers orientation and helps to prevent greenwashing. Sustainability must become part of a general mindset, including towards our travel behaviour. If I take a local trip by train I am reducing my carbon footprint. If I fly, will I stay longer at my destination instead of indulging in short trips? We all have to ask ourselves if we really need to jet somewhere to go shopping. I hope that soon this will no longer be hip and believe we will see this lifestyle changing in the near future.”

Sustainable tour operators offer many types of eco-friendly travel. They include companies such as Forum Anders Reisen, Gebeco and Intrepid Travel. According to the GCS findings, the potential exists in all the markets that were specifically examined (Germany, UK, USA). More than 40 per cent of those polled were willing to book a trip with a sustainable tour operator, and around 36 per cent were even willing to pay a premium for booking with one. However, in the past two years only 19 per cent of respondents had done so. Here too, time will tell whether travellers actually abide by their resolutions. Contradictions between one’s expectations or convictions and actual behaviour are not a new phenomenon, especially where protecting the environment is concerned. However, what is clear too is that travellers are not only aware of their individual behaviour, but also see the travel industry as having an obligation to provide attractive sustainable travel options.

Policymakers and tour operators must act
In the GCS, 92 per cent of travellers in Germany demand that policymakers and tour operators introduce measures for more eco-friendly holidays. For travellers in the US and UK, certification of eco-friendly resorts and providing information on a trip’s carbon footprint are a big factor. In Germany, banning private planes tops the list of measures (28 per cent, first place), compared with 19 per cent (fourth place) in the UK and 11 per cent (ninth place) in the United States. Tourists in all countries are unanimous that above all there needs to be more research (combined: 23 %) and investment (combined: 24 %) in eco-friendlier transport options.

International attendance was high, with 78 per cent of buyers and providers taking part from abroad. A total of 20,000 business contacts were made, resulting in 14,000 leads and 3,200 business meetings being arranged. As a virtual industry platform, the Digital Business Day augmented the ITB brand family and rounded off the trade show concept. In 2022, under the heading 'TRVLX by ITB', ITB Berlin is planning a series of B2B networking events in European markets – the kick-off event took place in May in Georgia. Before the pandemic at ITB 2019, around 10,000 exhibitors from 181 countries displayed their products and services to some 160,000 visitors, including 113,500 trade visitors.
