Hopefully, this will help you live within the planet’s means: work out your impact on the planet & plan your year ahead to reduce that impact to sustainable levels. Want to fly off on holiday? Well, turn your heating down a bit & buy fewer clothes so that you can. Read on and learn how to balance your budget!

To make lifestyle budgeting easy, I have translated all our ecological impacts into carbon emissions; or tried to. There is still a lot of uncertainty surrounding things like resource depletion, toxic emissions, habitat destruction etc. This lifestyle budget is based on so many shaky assumptions, rues of thumb, approximation and downright guesses that it probably all falls out in the wash anyway. Basically, it is a first approximation of a sustainable lifestyle to aim for. Something to work towards.

 All assistance in making it more accurate and inclusive will be most welcome! So far, this is how it works:

Every person on the planet has 3.5 tonnes of CO2 they can produce a year. Anything more is unsustainable, meaning you start to deplete resources and add to climate change. The following figures give you carbon outputs for various activities (emissions + ecological impact), so that you can budget properly: save a bit of carbon here to spend it there. Remember that things like electricity can be shared between everyone in the house – they are not per person, but per household.

 The basic figures for working everything out are given first, then examples about how to use them to plan your year’s activities to be sustainable: balancing your carbon budget.  

All figures are per year per household, unless otherwise stated.

 

Thing                                                                            Carbon emissions

 

Background life support                                                                 

Rubbish: recycling                                                                              0

Rubbish: wheelie bin to landfill                                                          5kg per bin

Electricity small house                                                                        1,500kg

                           Savings: being careful & turning everything off save 500kg*

                                          Using green tariff divide emissions by 5

 

                           Extras:    use a tumble drier? Add 640kg

 

*This means turning the TV & other kit off when not watching/using it, turning lights off when you leave the room, unplug chargers when not in use etc.

Heating with gas large house                                                              1,600kg

 Heating with oil small house                                                               750kg

Heating with oil large house                                                               2,000kg

Heating with electricity small house                                                   1,500kg

Heating with electricity large house                                                   4,000kg

                           Savings: well insulated and careful divide by 3.5

                                          Using green tariff divide by 5

                                          Turn the thermostat down save 200kg per 1oC

General water use (av person London)                                               17kg per person

                           Often used (12000 miles)                                        7,680kg

                           Hardly out of the car (20000 miles)                         12,800kg

                          

                           Commuting sums: rough length of journey one way x 480 = miles per year

Flying long haul                                                                                  70kg per hour flying

 

NB the driving figures are for the car – if there are multiple occupants, then they will share the carbon between them. Flying & public transport figures are per person.

 

Holidays

UK holidays do the transport only (car journey or public transport)

 

2 week holiday with short haul flight (1000km)                                450kg per holiday

NB the figures for holidays involving flying are per person

For 1 week holiday short haul is 400kg, long haul 1,400kg

Doing your budget

First of all, do not be afraid to use fudge-factors or estimates to extrapolate between the figures given. For instance, using a tumble dryer less will save some of the carbon: half your use & save 320kg.

 

So, take an example of an average family of four in a decent size house:

 

Total normal carbon spend per year (assuming they are a bit crap at turning things off etc)

Heating 1600kg

Rubbish (1 wheelie bin a week) 260kg

Electricity 3000kg

Water us (17kg each) 70kg

Washing etc (200kg each) 800kg

Food (1 main meaty meal a day each 4×1.5×365) 2190kg

Booze (1 glass wine a day for parents 2×0.2×365) 145kg

Car (12000 miles, fairly large but fairly new car) 3500kg

Stuff (buy £5000 of stuff a year total) 4000

 

Total: 16000kg carbon per year (roughly).

 

So, they want to live more sustainably, which means they need to get down to 3,500kg each: the total needs to come down to 14,000kg. They also want to go on holiday to Spain for 2 weeks. How can they do it?

 

In all they need to shave off 2,000kg from their normal lifestyles to become sustainable in everyday living, plus save another 1,800kg during the year to ‘pay’ for their holiday (which is 450kg each). So, in total they need to get their everyday living to emit 3,600kg of carbon less over a whole year. Tough call!

 

The first thing to do is start turning things off: never leave TVs blaring to an empty room, unplug all chargers when not in use, turn lights off when they leave the room, don’t leave stereos or games on standby and generally think about every way to reduce electricity consumption. Do it right and save 500kg. Then switch to a green tariff, like Ovo (about cost neutral to normal electricity suppliers & quite helpful – I use them), which will divide the remaining 2500kg by 5. Total saved on electricity use 2500kg.

 

Stop using the tumble drier most of the time & buy a drying rack (Brabanita do a good one) save 500kg. Heat the house to 1o lower, wear a jumper some of the time & save 200kg.

 

Stop buying so much unnecessary tat and start actually doing things with their time instead, save £2000 and 1,600kg.

 

Well, that takes them to 4,800kg saved over the year, which is more than enough for them to enjoy their holiday to the full! And all with very little effort and probably an improvement in lifestyle, as they will be pulling together as a family and doing more stuff rather than just shopping.

 

If they go even further and start eating less meat and get a veg box, take shorter showers, wash their clothes less and even use the car less (walking or cycling is very healthy anyway), then they should have enough carbon left over to go skiing. The money they save means that they will be able to afford it too.
