A Pescatarian adds fish to an otherwise Vegetarian diet with only a 2.5% increased climate impact. 

Food causes 20-30% of global greenhouse gas emissions. Changes to your diet can make a really significant difference.

A Pescatarian diet saves nearly 1.2 tonnes CO₂e over a standard UK meat eating diet per year.

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 suggest that we should eat only a limited amount of sustainable fish.

Look for the Marine Stewardship Council (MSC) logo .

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