ALLPLANTS CHALLENGE

The facts. 

FACT: Eating all plants is the #1 personal change any individual can make to combat climate change, bigger than switching to solar power or an electric car.

FACT: We'll reduce the carbon dioxide equivalent of taking 54% of cars off the road, all year, every year.


Datapoints:

  • UK population: 67.5M
  • 388kg CO2 saved per person by switching to 2 days. All plants. Every week. For a year. 
  • Totals: 26.2M tonnes of CO2 emissions saved

Cars:

  • Total car KM in UK per annum = 410Bn
  • 1 car KM = avg. 0.1185kg Co2
  • Total carbon emissions from car KM = 48.6M tonnes CO2.
  • 26.2M/48.6M = 54% of car emissions OR “taking 54% of cars off the road”

Trees:

  • Carbon saved eating an all plant diet 1 day / week = 3.8kg
  • Carbon saved eating an all plant diet 2 days / week for 1 year = 388kg
  • Trees absorb approx 20 - 30kg CO2 / yr (dependent on multiple factors)
  • Therefore 2 days allplants / week = ~16 trees worth of CO2 absorbed / yr per person (This is an average, but is very variable depending on tree type, soil type, rainfall, location etc)
  • 16 (average trees) x 67.5m (pop) = 1bn
  • We'll reduce CO2 in the atmosphere by the equivalent absorbed by 1billion trees every year.

FACT: Save enough water to provide 11 years worth of showers for every Brit


Datapoints:

  • UK population: 67.5M
  • Average water footprint of UK citizen = 4,600L daily (waterfootprint.org)
  • 3,000L (65%) of water footprint comes from diet (study conducted by European Commission), and vegan diet can reduce diet water footprint by 80% (Journal Nature Sustainability)
  • Two vegan days per week for a year results in an annual saving of 247,000L per person
  • The average Brit showers every day (Yougov), and consumes 62L per shower (BBC / Unilever)
  • So we’d individually save enough water (equivalent of 3,982 showers!) to provide showering for 10.9 years (rounded up to 11)
  • Demand for water will exceed supply by 40% in 2030.

FACT: Reduce the risk of heart disease by up to 20%, high blood pressure and diabetes. 


Datapoints:

  • You'll stop increasing your risk of heart disease by 13-20% by eating less red meat.
  • Plus, more plant diets are associated with lower risks of heart disease, high blood pressure, type 2 diabetes and obesity.
