A good example of the link between high income consumers and high carbon footprints, is air travel. Aviation accounts for 2.5% of global CO2 emissions (2) yet in anyone year only 5-10% of the world’s population boards a plane. And even within that minority who do fly, most of the flights are undertaken by an even smaller percentage of frequent flyers. In the UK (a country producing the third highest level of air flight emissions after the US and China) 70% of flights are taken by just 15% of the population. (1)
Does it have to be this way?
No – there are alternatives to air travel. Rail travel has a significantly smaller carbon footprint, and for travel within Europe and potentially across other continents, is practical mode of transport. However current investment plans and tax/ subsidy policies favour air travel over rail.
Government policies could start with the premise that the number of air flights needs to be reduced (or at the least kept at current levels). Shaping policies around that would include developing alternative modes of transport for people and goods, enabling manufactures to adapt to different transport network, encouraging different models of tourism.
