Currently, approximately 70% of fish eaten in Australia is imported and this significantly increases the greenhouse gas emissions through transportation and freezing. We haven't listed specific fish species to include or avoid in your diet, as this is entirely dependent on which state you live in - some species of seafood are overfished in WA, while being abundant in other populations such as NSW and QLD.
We recommend getting to know the species that are most often sold at your local fishmonger (yes, another way to shop local and reduce your imported products!). Once you have a feel for this, head on over to GoodFish - Australia's Sustainable Seafood Guide or download their app and make an accurate assessment based on your local area. As for other ways to reduce your carbon footprint when following a pescatarian diet, reducing your food waste, choosing less processed foods, and eating mindfully all play a significant part on reducing our overall climate impact. Additionally, we always recommend local and seasonal foods (learn more here).
