In the report "Future orientation of agricultural policy", the Federal Council shows how the Swiss agricultural and food sector can make an even greater contribution to food security in the future. The entire food system, from production to consumption, is included in the considerations. The strategy is to be implemented in three stages, one of which calls for more transparency in the use of environmentally relevant products.
