2. DEFINITIONS
(GENERAL)
The UN World Tourism Organisation
1. Take optimal use of environmental resources that constitute a key element in tourism development, maintaining essential ecological processes and helping to conserve natural heritage and biodiversity.
2. Respect the socio-cultural authenticity of host communities, conserve their built and living cultural heritage and traditional values, and contribute to inter-cultural understanding and tolerance.
3. Ensure viable, long-term economic operations, providing socio-economic benefits to all stakeholders that are fairly distributed, including stable employment and income-earning opportunities, and social services to host communities, and contributing to poverty alleviation.
Underpinning these three pillars are the core principles of sustainable development and social responsibility, as per academic findings: Environmental, social (or socio-cultural) and economical [tourism development]. Previous UNWTO explanations have said sustainable tourism takes full account of its current and future economic, social, and environmental impacts while addressing the needs of visitors, the industry, the environment, and host communities. Key takeaways are:
• Sustainable tourism is a continuous process and requires constant monitoring.
• It requires the informed participation of stakeholders (inc. host communities).
• Traveller’s awareness about sustainability issues is important.
• It promotes sustainable tourism practices.
• And finally, maintains a high level of tourist satisfaction and experiences.
The UNWTO One Planet Sustainable Tourism Programme addresses the mainstreaming of sustainable consumption and production (SCP) in tourism. It aligns sustainable tourism development with the World Commission on Environment and Development’s concept on sustainable development, i.e. “Development that meets the needs of the present without compromising the ability of future generations to meet their own needs. Sustainable development requires the elimination of institutional fragmentation ensuring that environmental, social, and economic concerns are integrated throughout decision-making processes and development that is fair, equitable and just.” It’s worth noting that sustainable development that benefits locals makes for a sustainable environment for tourism, too.
World Travel & Tourism Council (WTTC)
Initiatives cover:
• Climate and environment action
• Rethinking single use plastics
• Human trafficking
• Destination stewardship
• Biodiversity and illegal wildlife trade
• Sustainability leadership

The Global Sustainable Tourism Council (GSTC)
1. Sustainable management
2. Socio-economic impacts
3. Cultural impacts and preservation
4. Environmental impacts (including consumption of resources, reducing pollution, and conserving biodiversity and landscapes)
Under these pillars, there are detailed sustainability criteria for destinations, hotels and tour operators to use to achieve a GSTC badge or logo, showing a business qualifies for accreditation. As a summary, measuring, monitoring, reducing and reporting of impacts are key under every pillar.
The Travel Foundation (TTF)

6. CARBON CALCULATORS
There are many carbon calculators designed specifically to allow travellers to understand the carbon footprint of different travel activities – from flying to cruising to spending a night in a hotel, and many others. But there are some meaningful differences between the different calculators. These are the ones we use at Wanderlust:
Learn More
It’s useful for comparing train, bus, air, and car travel emissions all in one place, and with lots of options. You can even add in the number of nights you’ll be staying in a hotel at your destination, and it’ll include that in the footprint.
For flights, you can specify economy, premium economy, or business/first class. The calculation includes non-CO2 effects of travel, as well as even the emissions associated with manufacturing jet fuel. These factors make the results more aggressive than those from ICAO, but more representative of a trip’s true, total impact. For overland trips, you can choose the type of vehicle you’re driving, or the type of train – diesel or electric.

The ship and private aeroplane options are what make this calculator unique. It’s the only one we know of that allows ultra-luxury travellers to compare the emissions of dozens of models of private planes. (And allows the rest of us to see just how much worse they all are than flying commercial.)
Other than that, the methodology and results for flights are very similar to those from TravelAndClimate.org. They also give users the option to purchase verified carbon offsets for the trip after running a calculation.

Atmosfair includes non-CO2 factors in its calculation, just like Sustainable Travel International and TravelAndClimate.org (meaning other greenhouse gases, such as nitrogen oxide, and pollutants, such as soot particles, that also have warming effects.) The significant difference in their results comes from the fact that Atmosfair includes radiative forcing.
