Quantifying emissions from reducing meat in diets
Friends of the Earth wants to be able to roughly quantify emissions savings from reducing meat consumption in the average UK diet. This would sit in a pledge aimed at encouraging the public to eat less meat.
I'm looking for a good source for GHG/CO2e from meat in the average diet, so that we can calculate what cutting this eg by 25%, 50% and 75% could look like for emissions.
I've found this useful article http://link.springer.com/article/10.1007%252Fs10584-014-1169-1 by Scarborough et al, but the dietary info it uses fairly old, from 1990, and diets will have changed.
I know to do this accurately is hugely challenging given all the variables. I'm not looking at this stage for high levels of detail, but broad brush figures (and will give the necessary disclaimers!)
I'd really appreciate any pointers to any useful data. Thanks!
