2. Travel by land and sea

The document outlines a low-carbon travel target for UK residents, recommending zero car ownership and specific distance limits for trains, buses, and shared car use to achieve an annual emission level of 0.7 tCO2e per person.

• To meet the target of 0.7 tCO2e per capita per year in the UK, the suggested travel package includes up to 5,000 km of long-distance train travel, 5,000 km of bus and short-distance train travel, and up to 950 km of shared car travel (such as taxis or car clubs).
• Car ownership is generally excluded from the target due to the high carbon footprint associated with vehicle manufacturing. For example, the annualised emissions for manufacturing a medium battery electric car over a 14-year lifespan are 0.79 tCO2e/y, which alone equals the total annual target for all land and sea travel.
• The target recommends zero travel on cruise ships and minimal travel on high-emissions vehicles such as helicopters, steam trains, and speed boats. Ferry travel with a car is also excluded because a car's weight leads to approximately 20 times the fuel consumption of a foot passenger.
• The emissions calculations for rail travel are based on UK government conversion factors and lifecycle data, estimating 50 g/passenger-km for intercity trains and an average of 40 g/passenger-km for buses and short-distance trains.
