A 1.5°C compatible Switzerland
In late 2020, Switzerland formally updated its national determined contribution to achieving the Paris Agreement’s long-term temperature goal by targeting a higher level of domestic emissions reductions by 2030. This modest goal was defeated in a referendum on June 12, 2021.
While the current Swiss government has reiterated its commitment to 50% overall reductions by 2030, implementation now relies on the Federal Council’s 2016 recommendation to achieve a 30% reduction in domestic emissions by 2030, with the remainder to be attained through emissions reductions achieved overseas.
But is this 2030 goal enough to put Switzerland on track to achieve its goal of net zero GHG emissions by 2050 and preserve its glaciers?
- Switzerland did not ratify its recently submitted NDC in a June 12 referendum that rejected its updated CO2 Act. This severely limits its ability to reach a minimum 1.5°C compatible effort level of at least a 53% emissions reduction below 1990 levels by 2030.
- Its 2030 domestic target now falls back to a 2016 recommendation by the Swiss Federal Council of a 30% reduction in domestic emissions by 2030. This trajectory of emissions reductions by 2030 would make it difficult for Switzerland to reach its stated long-term target of carbon neutrality by 2050, and would lead to warming of 3-4°C by 2100 if followed globally.
- This level of warming would lead to the complete disappearance of nearly all snowpack and glaciers in Switzerland, according to projections.
- Switzerland’s 2050 net zero target is 1.5°C compatible, but without a sufficiently ambitious 2030 target, Switzerland is overall not aligned with the Paris Agreement’s 1.5°C long-term temperature goal.
- The full fair share 2030 contribution by Switzerland to global emission reductions consistent with the Paris Agreement includes support to developing countries reduce emissions on top of its own domestic emission reductions and is equivalent to an emissions reduction of 127% below 1990 levels. This means that if Switzerland achieved a 53% reduction domestically it would need to do the remainder through international assistance, finance or other support for mitigation in developing countries, which would have been provided at least in part by the Climate Fund that was part of the new CO2 Act defeated in the referendum.
- A new climate law provides an opportunity for Switzerland to both protect its domestic snow and water resources, and serve as a model for other nations by setting a 1.5°C compatible domestic emissions target of at least 53% below 1990 levels by 2030. As the Government wrote in 2018, “Switzerland’s credibility depends on its ability to live up to its responsibility as a contributor to climate change and as a prosperous nation”.
Unabated: the Carbon Capture and Storage 86 billion tonne carbon bomb aimed at derailing a fossil phase out
The climate talks at COP28 have centred around the need for a fossil fuel phase out. Our analysis quantifies the risk posed by restricting a phase out commitment to only ‘unabated’ fossil fuels.
No change to warming as fossil fuel endgame brings focus onto false solutions
The CAT's annual warming estimate has risen by 0.1˚C to 2.5˚C. The estimate is largely influenced by weak existing targets rather than shifts triggered by updated Nationally Determined Contributions.
When will global greenhouse gas emissions peak?
The IPCC says peaking before 2025 is a critical step to keep the 1.5°C limit within reach. With emissions set to rise in 2023, this leaves limited time to act. To assess if we can meet this milestone, we look at when global emissions might peak, as well as what we can do to get there in time.
Wind and solar benchmarks for a 1.5°C world
This report presents a detailed methodology for determining the amount of wind and solar capacity that is required for a country to align with the Paris Agreement’s 1.5°C temperature goal. While the focus of the report is the method, it includes illustrative benchmarks for Brazil, China, India, Indonesia, Germany, South Africa.
A 1.5°C future is possible: getting fossil fuels out of the Philippine power sector
The Philippines is also one of the fastest-growing developing countries: poverty is in decline, access to energy is rising and, with that, demand for energy services. However, fossil fuels still dominate the energy system, accounting for 78% of power generation in 2022. This report sets out what the Philippines government needs to do to get the country’s power sector onto a 1.5˚C compatible emissions pathway, replacing fossil fuels with renewable energy.
Production Gap Report 2023
Governments, in aggregate, still plan to produce more than double the amount of fossil fuels in 2030 than would be consistent with limiting warming to 1.5°C. The persistence of the global production gap puts a well-managed and equitable energy transition at risk.
Emissions impossible: Unpacking CSIRO GISERA Beetaloo Middle Arm fossil gas emissions estimates
This report provides an independent evaluation of the CSIRO and GISERA assessments of the potential greenhouse gas emissions that would result from the exploitation of the Beetaloo fossil shale gas reserves.
Adjusting 1.5°C climate change mitigation pathways in light of adverse new information
This study uses an integrated assessment model to explore how 1.5°C pathways could adjust in light of new adverse information, such as a reduced 1.5°C carbon budget, or slower-than-expected low-carbon technology deployment.
