Our present resource use: as if we had four planets...
"The industrial countries act as if there were several earths available. Thus, without a radical increase in resource producJvity there will be no sustainable development."

Material Footprint = Ecological backpack • Invisible material burden of a
product, service or lifestyle
• Considers the whole life-cycle: mining – manufacturing – consumption – waste disposal
• Includes abiotic resources, biotic resources and soil erosion in agriculture
• Can be applied on all levels: material, product, service, company, household, country, world

Factor 3 below average already achieved
Average Finnish household
Factor 9 difference between the households
Sustainable level 8 tonnes: nobody reached it
• 27 different Finnish households: 13…120 tonnes/cap./a (Kotakorpi et al. 2008)

NutriEon: 500 kg/a * 6 kg/kg = 3 tonnes/a
• 3 tonnes = 500 kg * 6 kg/kg = 600 kg * 5 kg/kg – Factor 2 decrease from now – 6 out of 27 FIN-‐MIPS households
already achieve 3.2 tn. or less – Cereals and bread, milk, eggs,
domesEc fruits, outdoor vegetables, soya, wild fish can already be below 6 kg/kg (Kauppinen et al. 2008, Kaiser et al. 2012, Mancini et al. 2011)
– Several European countries already below 9 kg/kg (Mancini et al. 2010)

Low-‐income households: already higher share of nutriEon (22 %)
• 18 Finnish low-‐income households: 7…30 tonnes/cap./a (Le4enmeier et al. 2012)

• NutriJon share on is likely to rise as raw material prices are rising
⇒ LimiJng budgets for other consumpJon purposes
• Can consumers avoid a strong increas of foodstuffs’ share in expenditures?
⇒ Decrease the material footprint of nutriJon without foregoing a healthy nutriJon
⇒ AdjusJng individual diets could contribute to economic and ecologic resilience while relieving personal budgets
⇒ Win-‐win potenJal
Higher prices?
