Transport accounts for around a quarter of all greenhouse gas emissions and across the world, many governments are implementing policies to decarbonize travel. You can get a head start: leave your car at home and walk or cycle whenever possible. If the distances are too great, choose public transport, preferably electric options. If you must drive, offer to carpool with others so that fewer cars are on the road. Get ahead of the curve and buy an electric car. Reduce the number of long-haul flights you take.
