What does sustainability look like in daily life? I thought I would share our (me and my husband) experiences.
The single biggest issue that affects the sustainability of travel is the use of fossil fuels. Fossil fuels are used directly in the form of petrol and diesel to fuel cars, motor bikes, farm vehicles, lorries … as aviation fuel for planes, diesel for trains where there is no overhead or third rail electrical current, the low grade petrol or bunker fuel used for ships. In addition fossil fuels are used indirectly where electric powered transport uses electricity non renewable sources. World wide transport contributes around one-fifth of global carbon dioxide emissions. (https://ourworldindata.org/travel-carbon-footprint)
Sustainable travel has to be that which minimises the use of fossil fuels.
Setting aside the means of transport used to get products from farms and factories to our homes and tables, and leaving aside the transport used by the emergency services etc. I shall focus on the transport solutions we use to get from A to B.
We live in a suburban part of London. We have good range of local shops for food, books, bikes, paper and craft materials, tools and timber, household and homewares. There are also schools, churches, gym, library, GP, green spaces all within a mile of our house.
- Our main mode of transport is walking. Cotton bags and rucksacks provide carrying capacity, waterproofs and umbrellas protection against the elements.
- Second to this would be cycling. This makes the dentist, swimming pool, theatre, cinema, shoes shops and department easily accessible – all within a half hour cycle. (Cycling is a would-be as my recent neck injury requires a year’s restraint from such activities). When I both worked and studied in central London, cycling was quick, reliable and enjoyable. A well maintained bike, panniers or rucksack, waterproof clothing, lights and a helmets are essential.
- Next comes the bus for short trips, plus the train and the underground network. This gets us all over London.
- Trains also provide long distance travel both here in the UK and across Europe, for holidays, visiting friends and families, etc. Starting off in London makes this easier: when we visit places less well served with public transport we do have to rely on family or a taxi to drive the last leg of the journey. Did you know you can go from London to Berlin or the Swiss Alps by train in a day? London to Glasgow or Edinburgh can be an overnight journey.
- Flying we avoid. Next year we would like to visit North America and are looking to travel with one of the passenger carrying cargo ships.
- There are some trips which we do choose to make by car. For example when my husband volunteers on a steam railway in Hampshire, or when transporting a model railway to exhibitions. At other times we use a taxi for my mother who struggles with escalators on the underground.
A rough calculation of the carbon footprint of the journeys I make annually by bus and train comes to 0.56 tonnes of CO2. If I were to make those journeys by car (even a reasonably fuel efficient one, 52 mpg) it would have produced 1.52 tonnes of CO2. If I had flown that same distance, it would have produced 2.27 tonnes CO2.
What I haven’t calculated is what my carbon footprint would have been if I had made all my local journeys by car rather than on foot. If say I normally walk 4 miles a day but instead make those journeys by car, I would produce a further 0.43 tonnes of CO2.
A further advantage of walking or cycling in terms of sustainability, is the low capital outlay or expenditure of resources. In the case of walking that would be resources used in making a pair of shoes, or for cycling, that of making a bike. Both will be significantly less than is needed to make a car. The resources needed to build a bus or train are considerable but when apportioned across the number of users and the life time of the vehicle, is probably less than the equivalent for a private car (which will often carry a single passenger as well as spending 95% of its life parked on a drive).
