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

•  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)

Low-­‐income  households:  already  higher  share  of  nutriEon  (22  %)

•  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?
