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.
Rubbish: recycling 0
Rubbish: wheelie bin to landfill 5kg per bin
Electricity small house 1,500kg
Electricity large house 3,000kg
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 small house 600kg
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
Showers, washing & washing-up (including hot water) 200kg per person
Savings: quick, low flow shower (3 minutes) reduce by 100kg
Wash clothes half as often & at 30o reduce by 100kg
Home grown (fairly organic) 0
Veggie (from veg box) 0.07kg per meal
Veggie (supermarket veg) 0.1kg per meal
Meaty & cheesy 1.5kg per meal
Ready meal/processed food 2kg per meal
Booze (shot of spirit, glass of wine, pint of beer) 0.2kg each drink
Coffee, tea, soft drinks 0.3kg per cup
Cordial & tap water 0
Car small, new & eco (160kg per 1000 miles driven)
Seldom used (3000 miles) 480kg
Often used (12000 miles) 2,400kg
Hardly out of the car (20000 miles) 3,2000kg
Car large, old & nasty (640kg per 1000 miles driven)
Seldom used (3000 miles) 1,920kg
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
Public transport (95kg per 1000 miles travelled)
Short commute (2 miles) 90kg per person a year
Medium commute (25 miles) 1,125kg per person a year
Long commute (75 miles) 3,375kg per person a year
Flying short haul 100kg per hour flying
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.
UK holidays do the transport only (car journey or public transport)
2 week holiday with short haul flight (1000km) 450kg per holiday
2 week holiday with long haul flight (5000km) 1,800kg per holiday
NB the figures for holidays involving flying are per person
For 1 week holiday short haul is 400kg, long haul 1,400kg
Consumerism (buying stuff)
General rule for everything 0.8kg for every £1 spent
Electronic stuff (TV, mobile, computer etc) 1kg for every £1 spent
Clothing 0.6kg for every £1 spent
Sofa 300kg each
Toys (general) 0.9kg for every £1 spent
Toys (plastic, electronic) 1.2kn for every £1 spent
Toys (eco) 0.2kg for every £1 spent
Appliance 680kg each
Waterskiing, motocross etc 0.7kg per hour
[sorry – the formatting of that has gone a bit weird from Word, but I really can’t be arsed to correct it]
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.
