What does this mean for livestock farmers? It's about changing the balance of land uses, not everything. Maybe a smaller herd, & a larger woodland.
There's profit to be had here: the most profitable 1/4 of small grazing livestock farms have 30% less livestock per hectare, but make 60% more profit

So this isnt just about emissions, it's about families being able to afford to feed their children a healthy diet. We dont have a level playing field as it is. Unhealthy food is constantly pushed at us in adverts, & promotions. That has to change for the sake of our health, and for the climate.

Healthy diets are also more sustainable. Red and processed meat increases the risk of heart disease, each 50g/day higher intake of processed meat increases the risk of coronary heart disease by 18%. Diet related ill health is costing the economy a staggering £268bn per year.

We do need supportive policy as the food system isnt working as it is. The most deprived fifth of households would need to spend 70% of their disposable income on food to feed them and their children according to the govt-recommended healthy diet.

3: But even this is conservative, as each generation is typically eating less meat than the last. Lamb consumption has fallen 59% since 2000, beef has fallen by 25%, and that’s without any policies to support more sustainable diets.

2: But actually, it’s not even going to be as noticeable as that.
Under 30s eat 26% less meat than those aged 75+, and 39% less red meat.
Even without anyone changing anything, by my assessments, in 2040 we’ll eat 14% less red meat per person, assuming new generations eat like current under 30s.

(or 2 less donor kebabs, if that's more your thing)

1: This isnt about everyone going vegan. The average person in the UK eats 2 burgers, 2 chicken breasts, 6 bacon rashers, 2 sausages and 4 chicken mayo sandwich every week.
By 2040, 25% less means switching 1 burger to a veggie burger, and eating three egg or tuna sandwiches rather than chicken.

Low-carbon farming measures are important, but we must lock carbon up in restored peat and trees, and that requires some changes to what's being produced and eaten. So the CCC recommend we eat 25% less meat in 2040. Sound a lot? Here's 3 reasons why it's actually not going to be that noticeable

A food strategy must provide better access to healthy, affordable food, tackle the environmental impacts of production, and support farms to deliver public goods alongside food.

For all of this & more, govt should look to Dimbleby's www.nationalfoodstrategy.org
