A pescatarian eats fish but no meat. 

If you cut out all meat to go pescatarian you’ll save an additional 200Kg CO2e per year.

It is a climate friendly diet, however concerns about the sustainability of fish stocks, harmful PCBs, farmed fish welfare and the spread of disease from farmed fish to the wild population question whether much fish really is sustainable. Pescatarians should take care not to add to the pressure on wild fish stocks or to support questionable fish farming practices and should eat only a moderate amount of sustainable fish.

Look for the Marine Stewardship Council (MSC) logo for reliable labelling of sustainable fish.

When eating out, put restaurants on the spot – ask whether their fish is sustainable.
