How carbon is embedded into daily household life
- Embedded emissions 66% (e.g things we buy, food, clothes)
- Direct missions from personal travel 10%
- Direct emissions from household energy use 24%
Carbon use by use:
- Recreation and leisure 27%
- Food and catering 24%
Time use of carbon:
- Can’t manufacture more time, so what swapping is done?
- What should be encouraged?
- Carbon emissions per hour
- Sleep and rest at 9 hours per day is really low carbon
- Commuting at .3 hours per day is really intensive
- Other household emissions of 5 hours per day aren’t a focus
- In leisure time, spending time with friends requiring travel is high carbon
Have money, so either will spend or save it: rebound effect
- Fuel efficient car with lower emissions
- but then lower petrol bills causes direct rebound
- Invest money saved into a holiday of spain is indirect rebound
- Embodied energy in the car itself?
Rebound effect of over 100% means emissions increased — is a backfire!
Rebound effects estimates
- Domestic use 0-32%
- Vehicle fuel use 25%-65%
- Reducing food use sometimes backfires.
Should try to minimize rebound
- Encourge green investment
- Shift pattern of expenditures to lower GHG
Which activities are fun and low carbon?
- Social activities
- Physical activities
- Goal orientated activities (in the flow, Csikszentmihalyi 2006)
- Being close to nature
Changing time use will change patterns of consumption, which can change patterns of production
- Number of hours we work? Reduce working time?
Work time reduction
- Need special measures for low income household
- Outcomes should be a scale effect that reduces incomes, expenditures and consumption
- Compositional effect, changes in time and expenditure budgets
- Increased wellbeing
- Reduced unemployment and inequalities
Some evidence (Sweden)
- Need to rethink the work-spend economy
- Focus on win-win
Outsource? Wash your own dog, or take to groomer?
- What type of activities?
- How many hours are you working?
