Food production: Emissions must be displayed comparably

Providing consumers with information about the climate impact of products can significantly reduce the environmental harm caused by consumption. Just as energy efficiency labels on home appliances and fuel consumption data for cars have guided consumer choices and influenced corporate behavior, similar labeling for food products could promote climate-friendly decisions.

If products clearly displayed their climate emissions on packaging, consumers could compare options from an environmental perspective, aligning with various budgets, preferences, and dietary needs. The most substantial climate impacts in food production often stem from raw material sourcing. Achieving significant emission reductions in primary production typically requires substantial investments, which the market currently does not sufficiently incentivize.

A standardized method for measuring and reporting the carbon footprint of food products would make climate actions more visible. Companies require data on food production's climate impact; legislation mandates that the largest companies report on their supply chain emissions. Many retail and food industry companies have voluntarily committed to reducing their emissions, necessitating the assessment and monitoring of emissions throughout the entire production chain.

While calculations for individual product carbon footprints have been done for a long time, they have not been widely adopted for consumer benefit on food packaging. Calculating emissions for individual food items is laborious, requiring the summation of emissions from various stages of the production chain. Historically, numerous calculation methods have been used, yielding results that were not highly comparable. However, the situation is improving, with concerted efforts in Finland to harmonize carbon footprint calculation methods and enhance data sharing. This push is supported by upcoming EU regulations based on an EU directive, which will address unsubstantiated environmental claims.
