Switzerland’s second nationally determined contribution under the Paris Agreement 2031 - 2035.

Switzerland’s second nationally determined contribution under the Paris Agreement is a national multisectoral document of Switzerland for the period 2031–2035. Its main objective is to set Switzerland contribution to the reduction of greenhouse gas emissions: by at least 65 percent by 2035 compared to 1990 levels, to be implemented as an emission budget covering 2031–2035. Thus, the target corresponds to an average reduction of greenhouse gas emissions by at least 59 percent over the period 2031–2035. Further, Switzerland communicates a net-zero target for all greenhouse gas emissions by 2050.
The reduction target must be achieved by reducing greenhouse gas emissions compared to 1990 in the building sector, in the transport sector (excluding international aviation), in the industry sector and in other sectors (from agriculture, waste, and from Greenhouse gas emissions footprint - i.e. consumption-based emissions over the whole life cycle - of food per capita).
The emission reductions targets, set by sector, imply remaining hard-to-abate residual emissions of CO2 equivalents by 2050, that will be addressed through carbon capture and storage (CCS) and carbon dioxide removal (CDR) or balanced by negative emissions. Also, all enterprises in Switzerland must reach net-zero emissions by 2050 at the latest, taking atleast direct and indirect emissions into account. After 2050, the amount of CO2 captured from the atmosphere and stored using CDR must be greater than the remaining greenhouse gas emissions.
The largest shares of greenhouse gas emissions in Switzerland arise from the transport and buildings sector. Agriculture and industry also contribute substantial shares to Switzerland’s total greenhouse gas emissions, while energy industries are less emissions-intensive when compared with many other countries. The Annex to Switzerland’s second NDC 2031–2035 outlines the elements though which Switzerland intends to contribute to the global commitments of the first global stocktake inscribed in Decision 1/CMA.5.
Those elements include, inter alia: 1) The energy transition, to be obtained through the (a) tripling renewable energy capacity globally and doubling the global average annual rate of energy efficiency improvements by 2030; and b) Accelerating efforts towards the phase-down of unabated coal power; (c) Accelerating efforts globally towards net zero emission energy systems, utilizing zero- and low-carbon fuels, well before or by around mid-century; (d) Transitioning away from fossil fuels in energy systems, in a just, orderly and equitable manner, accelerating action in this critical decade, so as to achieve net zero by 2050 in keeping with the science; (e) Accelerating zero- and low-emission technologies, including, inter alia, renewables, nuclear, abatement and removal technologies such as carbon capture and utilization and storage, particularly in hard-to-abate sectors, and low-carbon hydrogen production; (f) Accelerating the substantial reduction of non-carbon-dioxide emissions globally, in particular methane emissions by 2030; (g) Accelerating the reduction of emissions from road transport on a range of pathways, including through development of infrastructure and rapid deployment of zero- and low-emission vehicles; (h) Phasing out inefficient fossil fuel subsidies that do not address energy poverty or just transitions, as soon as possible.
2) Biodiversity, nature, and forests. Switzerland will contribute to the global commitments inscribed in Decision 1/CMA.5 of the first global stocktake on the importance of conserving, protecting and restoring nature and ecosystems towards achieving the Paris Agreement temperature goal (paragraph 33), including through enhanced efforts towards halting and reversing deforestation and forest degradation by 2030; on the need for enhanced support and investment, including through financial resources, technology transfer and capacity-building, for efforts towards halting and reversing deforestation and forest degradation by 2030 (paragraph 34); on the invitation to Parties to preserve and restore the ocean and coastal ecosystems (paragraph 35).
It will also contribute, with regard to 3) Sustainable lifestyles, sustainable patterns of consumption and production on the importance of transitioning to sustainable lifestyles and sustainable patterns of consumption and production in efforts to address climate change, including through circular economy approaches (paragraph 36).
