How essential is the weight-reduction plan from an environmental standpoint?

Crucial! The meals we eat accounts for a few third of whole carbon emissions, which is greater than all the transport sector.

In our analysis, we checked out how Swedes eat as we speak in a number of totally different dietary clusters after which optimized the weight-reduction plan in line with IPCC’s most restrict for emissions of about 1.6 kg of carbon dioxide per particular person and day. On the identical time, the weight-reduction plan needed to meet the Nordic Diet Suggestions and never price greater than present diets.

In your mannequin, a basic meat weight-reduction plan has to restrict its meat content material to at least one portion per week and as a substitute embrace at the very least one portion of lentils or beans per day to be climate-friendly. That is fairly an enormous distinction.

A low-income household with a number of youngsters might not have the time to make lentil patties or the cash to purchase recent greens, in order that they find yourself shopping for sausages or meatballs that they discover at a diminished worth. That may be ready rapidly.

What is required to result in change?

We’ve targeted loads on youngsters. Dietary habits are formed after we are younger, and in Sweden, all youngsters get free college lunches. In three analysis tasks, we have now step by step launched increasingly more plant-based meals in colleges to scale back local weather impacts.

First in Botkyrka, then in Uppsala and Lund. All of the meals from the unique menu remained, however we modified the recipes in order that, for instance, a meat stew had much less meat and extra legumes. The menu was nonetheless nutritious. However there’s additionally a necessity for a political change. Taxes or subsidies on meals have been proven to have the strongest impact on dietary habits. Extra data can provide each people and politicians the desire to affect in the correct route.
