With greater affluence, the opportunity to increase GHG emissions through 'energy rich activities' grows, while the relative financial incentive for cost effective emission reduction falls. With a higher income and children of their own to look after, our two subjects are faced with more and more GHG sensitive decisions. Mr Prescott sells his Volkswagen Golf and instead buys a new Volvo V70 Estate. This new car costs £673 in fuel and creates 5444kg of GHG each year. Mr Bellamy sticks to biking and public transport at the annual cost of £380 and with an associated GHG emission of around 528kg.
With growing families, the food purchases of both our subjects rise to 33kg of goods each week, with Mr Prescott continuing to buy without regard to 'food miles' the GHG arising from the transport of this food goes up to around 4368kg. Meanwhile, the transport of Mr Bellamy's food, sourced locally, gives rise to only 147kg of GHG over the course of a year. The increase in family size leads to Mr Prescott's household waste related GHG emissions rising to more than 1000kg. Mr Bellamy limits this increase by continuing to recycle paper, leading to a saving of 240kg of GHG a year.
The energy use of both Mr Prescott's and Mr Bellamy's family could be expected to rise into the 'high user' category at this point in their lives. Indeed, Mr Prescott's household energy related GHG emissions rise to over 13 tonnes per year at a cost of £739 over this period. Using various energy saving strategies, Mr Bellamy is able to cut emissions by over 4.5 tonnes below this level and save £154 in energy costs.
During this period Mr Bellamy opts to take his holidays in Skegness each year, travelling by rail at a cost of £43.20 and giving rise to around 13kg of GHG each time. Mr Prescott flies each year to Seattle at a cost of £249 and produces 2229kg of GHG on each round trip.
