How to improve environmental impact from
meals served in public sector?
Britta Florén, SIK – The Swedish Institute for Food and Biotechnology,
Dep of Sustainable Food Production, [email protected]
28th of May, 2013
Structure of my presentation:
1. Short about SIK
2. Overview of environmental impact of food products and some
brief methodology about LCA
3. Environmental impact of meals, example from a project
about carbon footprints from school meals
4. Improvement options
SIK develops products and
processes in the food chain
SIK has about 100 employees (more than one
third with PhD) to support food companies to
develop their products and processes.
This is achieved through:
• research (we are the world leader in several
areas)
• advanced consultancy and advisory work
• open and client-specific training programmes
• development of small companies

ENVIRONMENTAL IMPACT IS MUCH MORE THAN
CLIMATE CHANGE
ENVIRONMENTAL IMPACT FROM FOOD:
1) How many people need to eat

2) WHAT and HOW MUCH we eat

How to improve environmental impact from
meals served in public sector?
• Tool for working with climate change goals in the organisation
• Increase knowledge and show the importance of choosing the right
ingredients
• Example from a project : Climate change impact for school meals.
GOAL: Make it easier to choose the
”right” ingredients!
Focus on the meal!
• Typical Swedish school
meals (with the possibility
to make small changes)
• From a range of different
food ingredients
• LCA data available
• Same nutrient
requirements (protein,
carbon hydrates, fat)

Conclusions
• Reduce the amounts ingridients from animal products if possible
(feed production & methane from ruminants)
• Of the included ingredients beef has the highest climate change
contribution
• Vegetarian protein alternatives (lentils, beans, chick peas) make
a big difference
• Reduce the use of rice and instead favor potatoes, pasta and
pearled grain.
• From a meal perspective the climate change contribution from
one glass of milk is not negligible
How can we continue?
• With better knowledge easier to make choices…
• Change a little bit at a time…
• Communicate why you change
• Set up environmental goals and follow up
• Reduce unnecessary food waste

There are great potential in
reducing environmental impact
from food!
