La Svizzera deve fissare obiettivi ambiziosi nella lotta contro il riscaldamento globale e, in particolare, può abbattere le emissioni di CO2 dall'80 al 95% rispetto al 1990, secondo il parere dell'organo consultivo sui cambiamenti climatici (OcCC).
Gli esperti ritengono che Berna debba raddoppiare gli sforzi, dal momento che i costi dell'inattività sarebbero assai superiori all'ipotetico calo dei redditi, stimato tra lo 0,35 e il 2,5%, derivante da queste misure.
In proposito si raccomanda l'adozione di incentivi finanziari, tasse sulle fonti fossili, norme severe sui gas e il risparmio energetico e innovazione tecnologica.
