The Swiss Federal Office of Energy (SFOE) has come under fire for suppressing a study it commissioned, which found that replacing internal combustion engine cars with electric vehicles (EVs) is beneficial for the environment. The study, conducted by research firm Infras in 2024, concluded that upgrading to EVs would save CO₂ emissions immediately for over 90% of existing petrol and diesel cars.
The Buried Study
The SFOE paid 100,000 Swiss francs (approximately $120,000) for the study, which aimed to determine when it makes sense to replace gasoline cars with electric ones from a climate perspective. The results were clear: switching to EVs is environmentally beneficial, except for vehicles that are rarely used.
Why Was the Study Suppressed?
Despite the study’s findings, the SFOE chose not to publish it. Republik, a Swiss investigative journalism magazine, obtained a copy through freedom of information requests. According to emails uncovered by Republik, SFOE staff expressed concerns that the study’s recommendations “could be misinterpreted” and might be seen as “elitist” at a time when the federal administration is viewed negatively.
Implications and Reactions
The decision to bury the study has sparked criticism, with many pointing out that the science is clear: EVs are a net positive for the environment compared to fossil fuel-powered vehicles. Switzerland had set a goal for 50% of new car sales to be electric this year, but the current rate is around 30%.

Experts and environmental advocates have condemned the SFOE’s actions, suggesting that the decision may have been influenced by external pressures, potentially from “petro states” or associated companies. The incident highlights the ongoing challenges in promoting electric vehicles and combating misinformation in the face of powerful fossil fuel interests.
The suppression of this study demonstrates that there is still significant work to be done in advocating for environmentally friendly policies and technologies, particularly in the transportation sector.
