L'inquinamento di aria e acqua è drasticamente diminuito nel recente passato, ma le sfide che attendono la Confederazione a livello di politica ambientale sono ancora parecchie.
A queste conclusioni giunge il rapporto adottato dal Consiglio federale, in cui si traccia un bilancio sull'efficacia delle misure applicate, paragonandola poi con quella dei paesi limitrofi, e si presentano le prospettive con orizzonte il 2030.
Se l'andamento risulta positivo in molti ambiti, appaiono delle criticità per quanto concerne polveri fini, ozono e ossidi d'azoto, con limiti che restano superiori ai valori fissati dalla legge. Restano inoltre sempre sotto pressione le risorse naturali, a causa della pressione esercitata da ediliizia, trasporti e agricoltura.
