The CO2 Succession Act in Switzerland, accepted by parliament in March 2024, is set to be implemented from 2025 to 2030 and aims to reduce greenhouse gas emissions through various measures including a sustainable aviation fuel blending mandate, support for converting diesel-powered vehicles to fossil-free alternatives, and quantitative emissions reduction targets aligned with the EU. While the Act introduces penalties for exceeding emissions limits and continues some existing instruments like incentive levies, it notably omits additional measures that would be necessary to achieve Switzerland's climate targets, relying instead on financial incentives, investment in climate protection, and technological progress.
