A new report has highlighted how The Carbon Footprint of Global Tourism is 8% of global emissions, higher than previously reported. Why is that, and what can we do about it?
Our Climate Change article reported previous research that the sector was thought to contribute 5-6% of total global greenhouse gas emissions; three quarters (4% total) from transport, of which 40% (2.5% total) from aviation, and 32% (1.5% total) from cars; 21% (1% total) from accommodation, the rest from activities (UNWTO-UNEP-WMO, 2008).
Now, it’s being reported that global tourism accounts for 8% of carbon emissions. This higher figure is due to now including the full ‘life cycle’ of all the energy needed to support the tourism system, including food, beverage, infrastructure construction and maintenance as well as the retail services that tourists enjoy such as in hotels, shopping and souvenirs.
The new report found increases were driven by visitors from affluent countries who travel to other wealthy destinations: in particular, from the US, China, Germany and India, where much travel is domestic; and Canada, Switzerland, the Netherlands and Denmark from where travellers exert a much higher carbon footprint elsewhere than in their own countries.
Richer people tend to spend more on higher carbon transportation, food and pursuits: when people earn more than $40,000 per annum, their carbon footprint from tourism increase a disproportionate 13% for every 10% rise in income. People from low income countries spend more on public transport and unprocessed food. The growth of aviation means it is one of, if not the, fastest growing contributors to carbon impact and climate change.
This gives good indications of what we can do to reduce the carbon impact from our travels. Here’s our top 10 tips to How to reduce your carbon impact when travelling.
1. Fly less
Sounds obvious, but until alternative energy-powered planes arrive (around a decade away), we actually need to take responsibility for lowering our own aviation carbon impact.

See this map for flight greenhouse warming effect impact details.
We have got far too used to no-frills flights enabling easy-access weekend destinations. Although this a relatively new trend in the last 20 years, it is taken it for granted and its impacts infrequently considered.
- Avoid flying
- Flying for business: Do you really need to go? So much travel is business-related, much unnecessary for meetings. We now have access to many technologies and tools to give us face to face access to our colleagues. If you’re flying on a day return, ask yourself if it’s really necessary – save the travel time and have more talk time online instead.
- Take staycations: Can you at least take short breaks without flying?
- Fly less often: Take fewer trips. Some people limit flying eg. George Monbiot, the Guardian’s well known environmental journalist limits flying to once every three years.
- Fly less mileage: Consider shorter haul rather than long haul. There’s a greater impact of carbon at higher altitudes reached by long-haul flights. That said…
- Fly direct, without stop-overs - aeroplanes use a lot of fuel taking off and landing, representing a higher proportion of fuel on a short-haul flight.
So... multiple short-haul flights making up the mileage of one long haul flight may be 6 of one and half a dozen of the other…
- Make positive impact trips: Maximise the purpose/return you can give for your mileage. Tourism is a lifeline for developing countries: fly to support, rather than frivolously. You’re in the right place on earth-changers.com for some of the best positive impact tourism in the world.
2. If you fly, fly more carbon efficiently
- Fly Economy Class: Flying First Class or Business Class means more space per seat, which equates to more carbon per passenger, especially as these classes often have more unsold capacity and allow more luggage which adds to weight and carbon.
In 2013, World Bank research estimated the average carbon footprint by passenger by class: Business Class was three times that of Economy; First Class was nine times that of Economy. If all demand shifted to economy, over time, plane class configurations would be changed to match. A ‘double decker’ A380 may offer a lower carbon impact per passenger – but it depends how its seating is configured.
- Fly the latest planes: Buy your flight with an airline that offers the latest planes which offer greater fuel – thus carbon – efficiency; although it may be more expensive than an airline with old planes.
Atmosfair’s Airline Index compares and ranks the carbon efficiency of the 200 largest airlines of the world.
- Travel lightly: Your carbon footprint is heavier with heavier luggage, as airplanes’ fuel consumption is greater to fly greater loads. Take only what you need not just in terms of clothing, for example take travel size toiletries bottles that you refill and always reuse.
3. Consider the impact
A flight emits the same carbon emissions regardless. However, the impact of those emissions can be different according to how and when you fly.
Consider the contrails you see streaking across the sky - the line-shaped clouds of water vapour condensation. The combination of water vapour in aircraft engine exhaust, changes in air pressure and the low ambient temperatures that exist at high altitudes create their formation. They may last seconds, minutes or even hours and spread to being miles wide. Persistent contrails increase the cloudiness of the atmosphere and are suspected to have an effect on global climate. (Wikipedia)
- Altitude: Burning fuel at higher altitudes may have a strong multiplier effect: Even at 2% of global carbon emissions, aviation is thought to have 5% of global warming effect. Long haul flights fly at higher altitudes (longer) than short haul.
- Time: In the day, a plane’s contrails reflect the sun’s rays back into space. At night, they don’t – meaning the warming effect of contrails is doubled at night.
- Month: During winter months (Dec-Feb), planes produce more contrails in cold temperatures and high humidity.
4. Should you Carbon Offset?
Carbon offsetting is when you calculate the amount of carbon your journey will create and then donate money to remove the equivalent from the atmosphere, for example in planting trees or upgrading infrastructure to be more energy efficient. Sounds great in theory, right?
However, it’s not a solution: Offsetting does not reduce emissions. Therefore, offsetting does not solve the problem:
- Offsetting may appease guilt: This can create avoidance and complacency, diverting attention from addressing real mitigation, and understanding of the issues and need
- Offsetting only scratches the surface: If the emissions from the Global North were only reduced by offsetting, global emissions would not be lowered enough to reach the emissions targets for 2050 or 2100: Meeting the 2°C target requires global carbon emissions to be at least 80% below 1990 levels by 2050 and be reduced to virtually zero by 2100 (atmosfair).
- Offsetting mostly doesn’t work. An EU study in 2016 found 85% of then-current offsetting schemes don't work and 73% of the potential 2013-2020 schemes have low likelihood. Only 2% of projects and 7% of potential projects had likelihood of ensuring emission reductions.
- New doesn't replace old: Newly planted forests don’t replace primary forest and the biodiversity habitat they provide.
- Deforestation prevention is better than new reforestation: Deforestation and forest degradation are the second leading cause of global warming, responsible for about 15% of global greenhouse gas emissions, and the top cause in some countries such as Brazil and Indonesia. 80% of the Earth’s above-ground terrestrial carbon and 40% of below-ground terrestrial carbon is in forests.
Consider REDD+ the UN mitigation strategy:
REDD refers to Reducing Emissions from Deforestation and forest Degradation;
REDD+ refers to conservation and sustainable management of forests, and conservation and enhancement of forest carbon stocks / ‘carbon sinks’. Read more about the significant REDD+ project is managed by our partners in Kenya.
(And REDD++ extends REDD+ by low-carbon but high biodiversity lands)
Focus on innovation in carbon emissions reduction is required as one of the most cost-effective ways to lower emissions.
Is it worth offsetting to lessen negative impacts?
- Offsetting does not make sense on
- Products that are incompatible with a 2°C world with 8 billion people, e.g. daily meat consumption from mass livestock farming, offsetting the emissions of a steak house
- Obsolete products/services for which there is equivalent climate-friendly alternative already exists. Eg. Fossil fuel energy production.
- Offsetting can make sense:
- To make people aware of the carbon impact they are having
- When there is no realistic alternative that produces fewer carbon emissions
- Where convertible products/services could be developed into low-carbon products, but the necessary technology does not yet exist or is not yet advanced enough for the market.
- When offsetting follows strict standards and funds are used transparently and completely in a project which ensures emission reductions, credibly, accurately, reliably and verifiably, and which would not have been financed without offsetting via financing from CO₂ certificates (‘additionality’).
Flight offsetting falls into the third point – but its worth and success depends on the last point.
Ask any offset provider, where does your money go? How much goes to the project? What does it pay for? How much of the project is funded by offsetting? Can you see an annual report? How long has the project been going? What would happen to it if offsetting funds dried up?
Atmosfair enables you to calculate your flight emissions and offset to renewable energy projects.
You can also donate to Cool Earth to help them put local people as the custodians of the forests first and in control of the rainforests and work alongside these communities to half deforestation and climate change.
5. Take the train instead
Take the train from London to Paris rather than fly and Eurostar found you’ll cut carbon emissions by 90%.
Likewise Virgin trains reports London Kings Cross to Glasgow Central trains use 42.5kg of CO2 emitted. That’s 25% of the same journey by petrol car, 174.8kg, and 17% of that by plane, 244.2kg – the latter CO2 is around 1.25 double decker buses. (and that’s not taking into consideration airplanes’ emissions at altitude effect).
Carbon isn’t the only advantage of train travel over flying. It’s also
- Not necessarily longer: Once you take into consideration travel time to the airport, check in time ahead of the flight, baggage clearance time at the other end.
Friends at SnowCarbon tested this for a ski holiday in the French Alps – two people setting off together from London, one travelling via plane, one via the train – and arrived at the chalet destination just minutes apart. However the train traveller found it to be…
- Less stressful: Less queues than the airport, less lugging luggage around, and
- A lot more space: A big table, not strapped in seat belts, easy to work or play, eat or wander to the café/bar carriage… altogether more relaxing and time actually well spent!
- Get a sense of the country you’re travelling through: At Earth Changers we say take the train where can which offers much more opportunity to connect to a sense of place.
6. Take other public transport
- Coaches & buses emit less carbon than planes, where trains aren’t available.
- Coaches and buses may emit less carbon per passenger than cars - depending on passenger load and fuel: diesel, petrol or electric
7. In destination, use other methods of transportation
- Walking and cycling: Not only the most environmentally friendly A to B method of travel saving carbon emissions, but person-power is better for your health too.
- In 2014, transport sustainability researcher David Banister calculated the relative amounts of energy that different modes of transport consume, adjusted for carrying capacity (the Conversation): After walking and cycling, tram light rail came ahead of the bus, beating heavy rail, electric rail and diesel.
But remember there’s more to responsible tourism than emissions:
Animals used in transport, such as elephants or even horses, are often exploited and mistreated to be trained and managed for tourists’ benefit.
8. Stay in low carbon impact accommodations
There are many considerations for lowering impact in accommodation:
- Energy source: fossil fuel or renewable
- Energy consumption: for heating, air conditioning, lighting
- Energy saving appliances: light bulbs, switch-offs.
- Water heating: and hot water use, showers over baths
- Cooking fuel: and energy consumption
- Refridgeration: (preferably cool) temperature, location, use (such as cool foods first)
- Food: production, type, location and transportation: local, organic, less meat is preferable.
Likewise, there’s more to responsible tourism accommodation than emissions:
Where your money goes, staff employment and conditions, water infrastrcture, community support for poverty, agriculture, education, health, gender equality, other equalities, conservation, local infrastructure, partnerships and peace.
ie. It's complicated! This is where Earth Changers step in, to bring you the very best options in positive impact tourism. We do the hard work so you don't have to.
9. Choose lower carbon impact eating
Buying local organic food not only supports local staff and economy and your health, but also means
- Less imports: meaning less food miles.
- Less processed: meaning less energy consumption
- A plant-based diet: means less carbon emissions from meat farming and its linked deforestation.
10. Choose net positive impact activities
Applying the points above to apply to your in-destination time, and you’ll make wiser choices for activities’ carbon impacts while you’re there. For example, choose
- Walking / bike tours: over bus tours
- Local over chain: buy from local independent retailers and support the local economy
- Shop like a local and cook like a local
When you lessen your carbon impact, not only do you have a more sustainable trip, but you’ll also have a more authentic, local, better, experience!
