As people become more environmentally conscious, it's helpful to know which airlines are taking steps to reduce their carbon emissions. Discover the most eco-friendly airlines, what makes them more sustainable and steps you can take to lower your carbon footprint.
Alaska Airlines shows great transparency with regard to its CO2 emissions and other steps they are taking to improve its impact on the environment. They are always looking for innovative ways to reduce the environmental impact of their services, and steps that they have taken so far have included going strawless, composting grounds from coffee served in flight, and using avionics to use the 'Greener Skies' approaches in order to cut fuel consumption.
The airline has also formed a partnership with the Port of Seattle and Boeing with the aim to power all flights by all airlines at Seattle-Tacoma International Airport with sustainable biofuel.
Delta is taking steps to improve its environmental impact - largely with regard to its fuel emissions, but also with regard to water waste, hazardous waste, and the implementation of a recycling program.
On Earth Day 2019, Delta laid out a plan for the future and made clear its intentions to invest in carbon offsets by buying around 50,00 carbon offsets. Delta is also in the process of removing all single-use plastic items from their flights. This includes items such as stir sticks, wrappers and utensils. In total, Delta is estimated to remove over 300,000 pounds of plastic waste each year.
In March 2020, Delta Air Lines announced its commitment of $1 billion over the next 10 years on its journey to mitigate all emissions. In 2021, the airline will continue to invest in driving innovation, advancing clean air travel technologies, accelerating the reduction of carbon emissions and waste, and establishing new projects to mitigate the balance of emissions.
American Airlines has committed to investing in modern, more efficient aircraft - whether this is by investing in brand new aircraft, or upgrading planes not yet ready for retirement.
The airline looks for innovative ways to reduce costs and emissions, including installation of winglets to wing ends, shaving weight on aircraft, paperless cabins, and implementation of one-engine taxiing.
In 2020, the airline announced its goal to reach net zero carbon emissions by 2050.
Since 2008, KLM's climate action plan has ensured that the airline is more sustainable in the sky and on the ground. Responsible waste management, material recycling and measures to decrease noise pollution are just a few ways in which KLM has made steps to improve the environmental impact of the company.
Jetblue is committed to improving the airline's environmental impact and is proud to be transparent with regard to the steps taken in doing so.
The airline committed to moving away from using diesel and petrol for ground-based electric equipment such as bag tugs and belt loaders. In 2013, Jetblue introduced an onboard recycling program, alongside a partnership with Dunkin' Donuts, Jamba Juice and Royal Waste Services to compost food waste at JFK Airport's Terminal 5. The 'Jetblue T5 Farm' at New York's JFK Airport is the world's first blue potato farm based at an airport, and the T5 Rooftop is the only post-security outdoor space at a New York airport.
United Airlines is committed to a number of processes to ensure that the environmental impact of the company is as low as possible. This includes fuel efficiency and emissions reduction, using sustainable products, investing in sustainable fuel sources, and creating and maintaining partnerships to promote sustainability and protect the environment. In 2018, it announced that it would reduce its carbon emissions by 50% by the year 2050.
In June 2019, United launched a 'flight for the planet', which at the time, was billed as the most eco-friendly flight of all time. The carbon-neutral flight used sustainable biofuel and eliminated all cabin waste. Statistics from this flight included that 3.3% of fuel was saved compared to a typical flight, 40 tonnes of carbon dioxide was offset, which made up for the aircraft’s fuel consumption and also waste was down by about a third. United plans to learn from this flight, and turn these short-term initiatives into widespread policies.
United Airlines aims to launch electrically-powered flights by 2030 with the Heart Aerospace ES-30. This aircraft will be entirely electric-powered and have a seating capacity of around 30 passengers. United has already put in an order of 100 of the ES-30s and is currently leading the race to reduce the environmental impact the aviation industry has on climate change.
Easyjet is committed to the reduction of carbon emissions and invests in projects to ensure that the environmental impact of the airline is as minimal as possible. Example projects include new fleet investment, seat-weight reduction due to investment in new lightweight Recaro seats, paperless cockpits, adding 'sharklet' wing tips, and the addition of 6 more seats to existing A320 aircraft.
Cathay Pacific endeavours to 'be the world's best airline' and focuses particularly on the following environmental issues: climate change, waste, air quality, noise, water, conservation, and biodiversity.
The Cathay Pacific 'Fly Greener' programme gives Cathay Pacific and Cathay Dragon passengers the opportunity to reduce the carbon dioxide generated from air travel in a simple, credible way. Customers are able to purchase carbon offsets for their journeys, and the airline offers an online carbon offset calculator which allows passengers to work out what their journeys will use, and what they can buy to help to offset this.
British Airways strives to conduct business activities in an environmentally friendly manner and does this by committing to preventing pollution as much as possible, reducing pollution impact to be as low as possible, protecting the natural environment, reducing carbon emissions per passenger, reducing noise per flight, and minimising waste through the increase of material re-use and recycling.
In June 2019, British Airways revealed its newest eco-friendly feature to the premium economy cabin. Since then, passengers travelling in the World Traveller Plus cabin receive new amenity kits made from recycled materials such as plastic bottles.
British Airways also has plans to create a plant that will turn everyday household and commercial waste into jet fuel to be used for its aeroplanes. The legacy carrier plans to build the plant on a site in Lincolnshire and predicts that it will transform more than 500,00 tonnes of waste into fuel a year.
Loganair is forthcoming as the leading pioneer of electric aircraft. The Scottish regional airline wants to start using hydrogen-electric technology on its passenger flights by early 2030. Loganair is already making itself more environmentally friendly, with its use of renewable energy produced in Orkney.
Ryanair classes itself as 'Europe's greenest, cleanest airline', and was the first airline to commit to being plastic-free by 2023.
The airline's commitment to sustainability includes the following priorities: offering customers to offset the carbon cost of journeys, investing in new Boeing 737-MAX-200 aircraft, operating only point-to-point routes with industry-leading load factors, conducting operational efficiency, adding winglets to wings, and using single-engine taxiing between the runway and terminal.
The Australian airline Qantas has recently made a pledge to reach net zero emissions by 2050. They've also committed $50 million over the next 10 years to develop a sustainable aviation fuel in Australia.

Virgin Atlantic's top environmental policy is concerned with aircraft fuel and reduction of carbon emissions, alongside aircraft waste and noise, combined ground operations, and supply chain work.
Etihad Airways are partnering with the Abu Dhabi Waste Management Center on a project to explore how municipal waste can be converted into jet fuel. One of the aims of the project is to use the final jet fuel on Etihad Airways' flights. This shows the commitment that the airline has toward cutting-edge environmental advances and reducing the airline's dependency on fossil fuels.
In 2018, Xiamen Airlines launched a number of themed flights as part of its #WEINACTION campaign. The themed flights included customised meals, videos, radios and souvenirs that were used to raise awareness for 'life on land' and to protect terrestrial biodiversity. Xiamen Airlines continues to operate these themed flights periodically.
Air Canada began reducing the use of single-use plastic on all of its flights in 2019. The airline started by eliminating plastic drink stirrers with wooden drink stirrers, which will get rid of 35 million plastic drink stirrers yearly.
In 2020, the airline progressed in its work toward carbon-neutral growth for international aviation and continued to support the development of lower-carbon Sustainable Aviation Fuels (SAF) in Canada.
China Airlines offers 'ECO TRAVEL Carbon Offsetting' — a service that gives passengers the ability to partake in carbon offsetting and reduce their carbon footprint and emissions during their flight.
ECO TRAVEL Carbon offsetting lets China Airlines passengers track the emissions from their flight and — through UK company ClimateCare — gives them the opportunity to offset their carbon footprint with environmentally friendly carbon reduction projects.
SAS Scandinavian Airlines have set a goal to reduce its carbon emissions by 25% from 2005 to 2030. The airline has stated that updating its fleet and using biofuels will be the main two factors in achieving this. In 2018, the airline took in an order for Airbus A320 neo, which has reduced fuel consumption and emissions by roughly 15%. Furthermore, the airline plans to replace the amount of fuel used on all of its domestic flights with sustainable biofuel.
SAS has also invested in a carbon offsetting program which offsets all Business, Youth and EuroBonus passengers, as well as offering all other passengers the same option.
In 2019, SAS announced that it'll stop selling duty-free items inflight. This will help will reduce the overall weight carried on the aircraft and therefore result in the airline using less fuel per flight.
Cape Air has the intent to order a number ("double-digit") of Eviation Alice aircraft - an electric, 9-seater aircraft which is built from 95% composite materials, and set to be the first fully electric aircraft to enter commercial service.
New start-up airline, Ecojet (not to be confused with Bolivian 'EcoJet'), aims to operate flights with hydrogen-electric powered aircraft in 2026. Ecojet will be based in Edinburgh in the UK and will begin operations with a route between Edinburgh and Southampton, before eventually expanding into mainland Europe.

Despite what many speculate about air travel, it is in fact one of the most environmentally friendly ways of travelling. The average fuel consumption per transported passenger by an aeroplane is below 4 litres per 100km and as airlines make efforts to improve fuel consumption to meet targets set internally and within the industry, this figure will be improved upon year on year. There are many ways in which an airline can strive to be more eco-friendly, including:
Older aircraft use more kerosene, amongst other materials. Newer aircraft also have winglets, which are added to the end of wings to reduce drag and fuel consumption.
The use of more environmentally friendly materials not only applies to the aircraft itself (such as installing carbon fibre seats), but also the materials used for magazines (and even cutting them out completely), beverage carts (making them lighter), and removing in-flight telephones.
Many airlines are expanding vegan and vegetarian in-flight meal options, as a result of changing consumer demand. Meatless in-flight meals are more environmentally friendly, as industrial meat production has a negative impact on the environment.
Many low-cost, no-frills airlines lead the way with the aim of being more environmentally friendly, due to the fact that they 'unbundle' fares, allowing passengers the choice of what to purchase and what to leave out. Not only can this save travellers money, but this can also be more environmentally friendly, due to many choosing carry-on bags only, which as described in our tips for environmentally friendly travel, is a greener way to fly.
