The paper compares the environmental impacts of meat and meat alternative products such as plant-based sausages or burgers, and finds many meat alternatives had a fifth to less than a tenth of the environmental impact of meat-based equivalents.A study estimating the environmental impact of 57,000 food products in the UK and Ireland has been published.
