• Regulations: national & international influencing carbon, land, inputs,
consumption
• Resource pricing land, water, fuel etc
(incl PES and carbon pricing).
• Resilience issues: environmental and
climatic change, extremes and variability,
absolute scarcity
• Reputational issues: driven by NGOs,
media, policy
• Randoms: extreme weather,
technological breakthroughs, cultural
tipping points, wars

Studies generally:
• Define sustainability in environmental terms (often
just GHGs)
• Are rich-world focused
• Ignore wider socio-economic context
• Don’t consider other determinants of nutritional
status
• Don’t consider non-nutritional health implications of
food
And so, with these (enormous) provisos, can we define
Good-enough / interim /partial
Principles of environmentally sustainable and nutritious diets?
• Diversity – a wide variety of foods eaten
• In energy balance
• Based around: tubers and whole grains (but not rice); legumes;
fruits and vegetables - field grown and robust
• Meat eaten sparingly if at all - all animal parts consumed
• Dairy products or fortified plant-substitutes eaten in moderation &
other calcium-containing foods consumed
• Unsalted seeds and nuts included
• Some fish and aquatic products sourced from certified fisheries,
although less frequently than Eatwell advises
• Limited consumption of sugary and fatty sweets, chocolates, snacks
and beverages
• Tap water in preference to other beverages
Health & environment: an arranged marriage, not a love match
Sustainable but unhealthy
Healthy and sustainable
• Mainly grains (except rice), tubers and
legumes
• low in nutrient rich foods including
fruits, vegetables and animal products
• Low waste and energy but high risk
storage and cooking practices
• Low in animal products
• Low in processed sugary foods
• High in robust, field grown, seasonal
vegetables & fruits
• Rich in legumes and moderate in nuts
• Occasionally fish from certified stocks
• Food purchased is not wasted and
cooked efficiently
Unsustainable and unhealthy
Healthy but unsustainable
•
•
•
•
• Moderate levels of lean meats
• High levels of resource intensive
vegetables and fruits (eg. air freighted
produce and 'ratatouille' vegetables and
salads produced out of season
• Fish consumed from unsustainable stocks
• High dependence on chilled produce
• Inefficient cooking methods and high
levels of waste
High in animal products
Low in vegetables and fruits
Low in grains and tubers
High in energy and fat dense, nutrient
poor processed foods
• High levels of food waste and inefficient
cooking methods

Different kinds of meat
Different ways of producing it
Multiple environmental & nutritional issues
The ‘less and better’ concept…BUT
(Loosely) adapted
from Prime cuts,
FEC/WWF-UK, 2013
Affordability?
Cheap
intensive meat
Nutrition?
Low fat,
grassfed
Taste?
Whose taste?
Waste
minimisation?
Sausages,
pasties &
nuggets
Better
for
what?
Resource
efficiency?
Extensive
ruminants
2-for-1?
Dairy cattle beef as
byproduct
Landscape &
aesthetics?
Go for grazing
GHG
emissions?
Intensive
battery
chickens
Employment?
Need to look
along whole
supply chain
Animal
welfare?
(Probably) go
for freerange

Ways of approaching the issue
Influenced by:
• Ideologies & values
• Disciplinary training
• Sectoral lens
Categorisation lens
Example
Actor (ie. change agent)
eg. Farmers, food industry, media, public institutions, social
network/group (eg. transition towns group, weight-watcher group)
national, international and local level policy makers)
Target group (ie. group
whose behaviour is to be
changed)
Value frame
eg. Food producers, food manufacturers and retailers, and eaters (defined
variously as individuals, families, consumers, citizens)
Space & place
eg. Place of production - farm, factory; place of retail - shops; place of
consumption - canteens, restaurants, home; place of confinement schools, offices, hospitals, prisons; journey to work; location of food
provision
Timing - life course
eg. Life stage - starting school, pregnancy, marriage, retirement
Timing - eating occasion
eg. Breakfast, lunch, dinner, snacks, celebration meals, on the go eating
Intervention theory
eg. 4Ps of marketing theory, Defra’s 4 Es framework, Michie and West
behaviour change wheel, Nuffield Ladder, Nudge
Transparency to end
consumer
eg. Product reformulation (where the consumer may not even realise
they are consuming differently) through to rationing
Coerciveness
eg. Education, pricing changes, regulation
eg. Health, environment, animal welfare, coolness, parental instincts; or
more generally: intrinsic values versus extrinsic motivations, altruism
versus self interest; citizen vs consumer; individual fulfilment versus
societal goals

A hypothetical example in a SM context
Replace
Greater provision of vegetarian meals, promotion of fruit and
vegetables, meat substitutes (e.g. veggie burgers)
Reduce
Adjusting portion sizes of carcass meat or in ready meals
Reformulate
Increasing the veg: meat ratio in composite meals
Rebrand
Promoting or refreshing products that are already vegetarian
Respect
Meat as a ‘Sunday-special’ or celebration food; promoting
‘nose to tail’ eating; “meat as flavouring/garnish.”
Reprice
Making vegetarian alternatives more attractive to shoppers
Thinking about interventions also
need to bear in mind
• Cross-transferability from other areas (eg. how
far are successful interventions wrt drugs or driving applicable
to food?)
• Risk of perverse side effects
Intervention effect Change in practice
People eat less meat but more refined, processed
Doughnut effect
carbohydrates
Blueberry effect
Sausages effect
People eat less meat but more high impact fruits &
vegetables
Higher meat prices cause people to cut down on their
meat spending but maintain quantity by eating less
healthy meats such as sausages or fatty mince.
Outcome
Lower GHGs but poor nutritionally and other
environmental downsides
Possibly good for health but potentially higher
GHGs
The impacts on GHGs are unclear; there will be
benefits for resource efficiency; impact on
health poor
Red to white effect GHG oriented policies cause people to shift from red
meat to white
Reduced GHGs, impacts on health and other
environment mixed; potentially negative for
AW
Meat-shoring
effect
Higher meat prices lead to increased spending on
meat (maintaining consumption) but reduced intakes
of fruit and vegetables
Negative outcomes for health and for the
environment.
Welfare effect
People maintain their levels of meat consumption but The impacts on the environment will be mixed,
impacts on health may be neutral or negative,
buy lower welfare meat instead.
impacts on welfare across many (not all)
welfare indicators poor
Halo effect
People shift to a more sustainable diet but feel
justified in buying that new iPad or flying off on
holiday.
Impacts on health positive, impacts on
environment depend on the substitute
consumption practice
Leaky system effect People in the UK consume a more sustainable diet but No net benefit - impact swapping
farmers increase exports; or UK reduce production
but meat imports increase
Employment effect People eat a more sustainable diet; livestock farmers
go out of business and either remain unemployed or
are employed in other sectors
Net health & environment impacts depend on
a. health impacts of employment changes b.
environmental impacts of substitute activity.

What do we know?
What don’t we know?
Where do we know enough to justify action now?
Where is more understanding is needed?
What sort of research would help improve the
evidence base needed for effective policy
making?
• Can we put all that in writing by the end of
tomorrow?
