You can get flights to Toronto from London with airlines that offer eco-friendly options. As it’s better for the environment to take direct flights, you could choose environmentally-friendly airlines such as Air Transat, British Airways and Lufthansa. These airlines all have pledges to reduce the amount carbon emissions associated with flying in the coming years. Air Transat uses the Airbus A321neoLR, which is fuel efficient and also produces some of the lowest amounts of greenhouse gases. British Airways is using lighter in-flight equipment and seats, which saves on thousands of tonnes of carbon dioxide each year. Whilst Lufthansa are replacing plastic products in catering with more sustainable materials. If you want to enhance your sustainable travel, then it is always a good idea to compare airlines before you book, as their environmental impact might vary from route to route.

One of the best ways to have a more eco-friendly flight from London to Toronto is to choose a flight that departs in the day. When you fly in the day, the impact of condensation trails is far less than compared to when you fly at night. During the night, these trails of condensation create a much thicker thermal blanket which traps more heat in the atmosphere. Another way that you can be sure your journey is more sustainable is to look for an airline that has a modern fleet. For example, Lufthansa has a state-of-the-art fleet which produces lower emissions. Taking direct flights as opposed to indirect ones is also a great way to reduce the impact that your journey has on the environment. Not only will you fly fewer miles and therefore use less fuel, but also the energy consumption during take-off and landing is far higher than when you’re cruising, so it's better to only do it once.
