Climate fee on food could effectively cut greenhouse gas emissions in agriculture while ensuring a social balance

agriculture accounts for 8 percent of all greenhouse gas (GHG) emissions in Germany. “However, emissions within this sector, could be reduced by 22.5 percent or over 15 million tonnes of GHG annually, if the social cost of carbon were reflected in food prices,” says Julian Schaper, guest scientist at PIK and lead author of the study published in the journal Food Policy. In the Federal Climate Change Act passed in 2019, the government set itself the goal of reducing annual emissions from the current 62 million tonnes to 56 Mt GHG by 2030.

The social cost of carbon is an estimate of the economic damages that would result from emitting one additional tonne of carbon into the atmosphere in the future. Emission-intensive products such as meat and dairy would be most affected by such a climate fee of around 200 euros per tonne GHG, while prices for more sustainable products would rise less: Yoghurt and milk would increase by about 25 cents per kilogram, while beef prices could rise by over 4 euros/kg.

Using a demand model that provides a detailed and representative picture of how German households respond to price changes, the researchers assessed the effects of GHG pricing on consumption and associated emissions. “Households would tend to buy more food that is less carbon-intensive on average, such as vegetables. A climate fee would not only directly benefit climate protection, but could also encourage sustainable consumption,” explains PIK scientist Max Franks, author of the study.

In the researchers' model, the 8.2 billion euros generated by the climate fee are returned to consumers as a climate dividend, providing substantial relief to lower-income households, while wealthier households would bear slightly higher costs. "This form of redistribution helps to create a social balance that can promote the acceptance of such measures," Franks continues.

The authors of the study also see significant potential for broad public acceptance in the combination of a climate fee and dividend. It is crucial to clearly communicate that the measures effectively reduce emissions, that all revenues are returned to the public and that lower-income households are specifically supported.
