Slide 26

Can we ‘keep the lights on’ with a 100% renewable and carbon neutral energy system? Can we provide a healthy low-carbon diet for the UK population? New research


Slide 27

A technically robust scenario in which the UK has risen to the challenge of climate change.


Slide 28

Net zero across all greenhouse gas emissions (not just energy), using technology we have now.


Slide 29


Slide 30

From this …


Slide 31

… to this


Slide 32

Without major impacts on quality of life (in fact, we think this future looks pretty good)


Slide 33

We have to see the future like this No ‘business as usual’ future is available.

Slide 58

Today ZCB Biomass 70% of our land (85% livestock) 55% of our food


Slide 59

Today ZCB Biomass


Slide 60

Land use in ZCB There is enough space for: Food Biomass Natural spaces


Slide 61

Food + diets model: nutrition, emissions, land


Slide 62

Land use GHG emissions today ~ 10% of UK total


Slide 63

Agricultural GHG emissions today ~ 10% of UK total


Slide 64

Current average UK diet 64% of adults overweight/obese (Bates et al, 2011). 71% of deaths in 2010 from diet- related disease (WHO, 2013).


Slide 65

Current average UK diet 64% of adults overweight/obese (Bates et al, 2011). 71% of deaths in 2010 from diet- related disease (WHO, 2013). Too much food.


Slide 66

Current average UK diet 64% of adults overweight/obese (Bates et al, 2011). 71% of deaths in 2010 from diet- related disease (WHO, 2013). Too much food. An unhealthy balance.


Slide 67

Current average UK diet 64% of adults overweight/obese (Bates et al, 2011). 71% of deaths in 2010 from diet- related disease (WHO, 2013). Too much food. An unhealthy balance. Too much HFSS and high protein foods. Too little fruit, vegetables and cereals.


Slide 68

Current average UK diet 64% of adults overweight/obese (Bates et al, 2011). 71% of deaths in 2010 from diet- related disease (WHO, 2013). Too much food. An unhealthy balance. Too much HFSS and high protein foods. Too little fruit, vegetables and cereals. Waste (30% in Europe (FAO, 2011)).


Slide 69

Food + diets model: nutrition, emissions, land


Slide 70

Change our diets


Slide 71

Change our diets Switch high protein foods 5-6 portions meat/dairy/eggs. 4 portions ‘alternatives’ (beans, pulses etc). + Milk for tea/coffee.


Slide 72

Change our diets + halve food waste + improve agricultural practices = Emissions - 75%


Slide 73


Slide 74

85% of our food 55% of our food


Slide 75


Slide 76

Grow all the biomass need


Slide 77

Capture remaining carbon Safe, proven, long- lasting methods: Restore 50% of peatlands Double forest area More use of UK wood products


Slide 78

This is how it works.


Slide 79

Net zero GHG emissions is possible. Using technology available now. Without major impacts on quality of life.


Slide 80

We can provide a reliable energy supply. 100% renewable/carbon-neutral. No nuclear, no fossil fuels. Using technology available today. ZCB also shows that
