Numbers & such

We all know that dads love stats, maybe as much as they love eating meat and dairy. So what happens when these two loves go head to head? Try throwing dad some of these jedi-level climate stats and let’s find out.

Not-so-fun-facts

The UK produces 15 billion litres of milk per year, and the average Brit consumes 70 litres of milk per year, roughly 1.4 litres per week.*

Emissions
Emissions from the global livestock supply chain are estimated at 7.1 Gigatonnes of CO2e per year.** That’s taking a lifecycle approach and looking at the whole supply chain including emissions from animal digestion and manure but also emissions involved in producing feed, using fertilisers and land usage, as well as processing and transporting meat and dairy.

To put that figure in context, the emissions from all the world’s cars, planes, trains, boats, go-carts, etc. combined is estimated at 7.0 Gigatonnes of CO2e*** (that’s driving, flying or sailing them, not making them, extracting fuel or scrapping old cars).

So yeah, food choice matters.

Cows milk vs. Oat Drink
Oat drink generates 73% less CO2e than cow’s milk – yeah!****

Climate

To meet the 1.5-degree goal set by the Paris Accord, we need to cut global greenhouse emissions in half by 2030.*

Climate compensation
If you travel by plane and “compensate” by planting trees, theoretically you will be even-steven (if the trees do not die or are cut down) in 30 years, which is tricky given that we must halve our global greenhouse gas emissions by 2030.**

Upgrade your diet
Switching to a “planet-based” diet can reduce***:

  • Food-based greenhouse gas emissions by at least 30%
  • Wildlife loss by up to 46%
  • Agricultural land use by at least 41%

Animal factory

Mammals of the world *

Raised livestock: 60%
Wild animals: 4%
Humans: 36% (incl. dads)

60% of the entire mammalian population on Earth consists of human-bred livestock. People (including dads) make up 36%, and only 4% of all planetary mammals are wild.*

Land usage
50% of the world’s habitable land is used for agriculture. There is a highly unequal distribution of land use between livestock and crops for human consumption. If we combine pastures used for grazing with land used to grow crops for animal feed, livestock would account for 77% of global farming land. While livestock takes up most of the world’s agricultural land, it only produces 18% of the world’s calories and 37% of total protein.**

Eating animals
Our appetite for meat keeps getting bigger. A review by the Food and Agriculture Organization projects an increase of 76% in the total quantity of meat consumed by 2050.***
