Reducing the carbon footprint of diets across socio-demographic groups in Finland: a mathematical optimisation study.

ABSTRACT:

Objectives

To characterise nutritionally adequate, climate-friendly diets that are culturally acceptable across socio-demographic groups. To identify potential equity issues linked to more climate-friendly and nutritionally adequate dietary changes.

Design

An optimisation model minimises distance from observed diets subject to nutritional, greenhouse gas emissions (GHGE) and food-habit constraints. It is calibrated to socio-demographic groups differentiated by sex, education and income levels using dietary intake data. The environmental coefficients are derived from life cycle analysis and an environmentally extended input-output model.

Setting

Finland.

Participants

Adult population.

Results

Across all population groups, we find large synergies between i
