WP7 Environmental assessment of
lifestyle and economic alternatives
Main objectives:
•
Which lifestyles are more or less sustainable from a climate and
environment perspective?
•
Which lifestyle changes would contribute significantly to achieving
the EU’s sustainability targets?
•
How do changes in technology and alternative economic system
affect the efficacy of lifestyle change for achieving sustainability?
•

Household Environmental Impacts (HEI)
Direct Impacts:
Through the use of products
Direct Carbon Emissions:
• Driving a car
• Using fuel to heat up a
house
• …
Direct Water Use:
• Using water for
showering and toilet
flushing
• …
Indirect Impacts:
Through the Impacts Embodied in Purchases
Indirect Carbon Emissions:
• Embodied in generation
of electricity
• …
Indirect Land Use:
• Embodied in agriculture
and food production
• …
Indirect Material Use:
• Embodied in
construction
• …
Indirect WaterUse:
• Irrigation of crops
• …

Environmentally Extended
Multiregional Input-Output
Analysis
•
All flows of goods and services in a given
year purchased by industries and final
consumers

Important findings in the literature
• The higher the expenditure, the higher the impact
• Shelter, mobility, food and the consumption of
manufactured products are most important
• Shelter: size, heating technology and insulation important;
behavioral aspects important
• Mobility: car ownership, car type important
Air transport crucial
• Food: Meat and dairy products have higher impacts than
land-based products; cooled/refrigerated food and air
freight contribute significantly
• Manufactured products: Volume important; replacement
rate

region vs case study
Spillover and tradeoffs
•
Econometric and Statistical analysis of our own results and available data (surveys) to
identify drivers and their contribution to env impact.
•
Cross-sectional analysis, in case studies regions, to validate our model.
•
Sensitivity Analysis: account for changes in variables that cause significant changes of
household environmental impacts

Research questions on case study
regions and initiatives
How important are the areas of behavior targeted
by lifestyle initiatives in terms of their
environmental impact?
How much better are behavioral alternatives in
terms of their environmental performance?
What is the environmental impact of specific
activities traced by the time use survey?
What are spill-overs and rebound effects?

Task 7.4 Scenarios for the impact of green
economy and resource efficiency
First steps: Identify the situation today to be used as baseline.
Assessment of the effects of transitions in lifestyles :
System level policies (tech transitions, infrastructure regime level) + HH policies
Compare results to climate goals or other desirable scenarios (backcasting)
Variables
• Technological-economical changes
• Socio demographic changes
• Resource competition/depletion
• Behavioral changes
