So maybe the study answers it but that is a lot to read through for one answer, but my big question that you did not quote is still. > I would also really like to see how the dietary enviromental impact relates to a persons entire environmental impact (as in, ok we see a 30% impact change based on dietary impact but how much of a change is that on a personal level really?) That is information I am struggling to actually find. 30% of one of impacts is a decent amount but I also don't own a car. How much of my entire environmental impact is my diet? They also seem to be grouping all meat together. Like Beef and Chicken. According to https://ourworldindata.org/environmental-impacts-of-food https://ourworldindata.org/environmental-impacts-of-food there is a massive difference between the impact of Chicken vs Beef. I searched that report for chicken (never came up) and Poultry (came up twice). So I am very curious how they are actually coming to these numbers when all of the types of meet vary wildly in their impact.

> So maybe the study answers it but that is a lot to read through for one answer, but my big question that you did not quote is still. I don't know whether there is an official answer, but if you look at your link there, it says, e.g. 1 kilo of poultry creates 10 kilos of CO2. The average american produces 14k Kilos of CO2/yr, so if you ate a kilo of chicken a day, you're looking at about 3k Kilos of CO2, or something like 20% of your carbon. If you eat a kilo of beef it's like 250% of the average carbon footprint a year. That is a LOT of meat, but overall, you can guesstimate this is like 10-20% of your carbon footprint if you eat a lot of chicken, and maybe the bulk of it if you eat a lot of red meat. It seems like chicken is better than fish is wayyy better than red meat.

  > It seems like chicken is better than fish is wayyy better than red meat. You're right, but only if you count carbon footprint. You also have to count in destroyed/damaged/polluted ecosystems, elimination of wildlife, deforestation, energy, etc. etc. if you WANT to have a complete picture. For CO2 numbers, you can see the original study Reducing food’s environmental impacts through producers and consumers https://www.researchgate.net/publication/325532198_Reducing_food%27s_environmental_impacts_through_producers_and_consumers https://www.researchgate.net/publication/325532198_Reducing_... or the graph listing more kinds of meats here: Avoiding meat and dairy is ‘single biggest way’ to reduce your impact on Earth https://www.theguardian.com/environment/2018/may/31/avoiding-meat-and-dairy-is-single-biggest-way-to-reduce-your-impact-on-earth https://www.theguardian.com/environment/2018/may/31/avoiding...
