The Canton of Zurich has made visible progress on climate, mobility, food, habitats and the circular economy, but its new environmental report says many key targets remain unmet and that stronger action is needed, particularly to curb nitrogen pollution.
The Umweltbericht 2026, published on 9 November 2026, is the canton’s four-yearly assessment of its environmental situation. It covers mobility, nutrition, biodiversity, climate and noise, and assesses both the effectiveness of cantonal measures and the remaining gaps.
One of the report’s most critical findings concerns nitrogen.
Measurements at Bachtel show that nitrogen inputs have barely declined since 2000, despite more than two decades of environmental policy.
The canton says further measures are needed to stop over-fertilisation, a problem that affects ecosystems, biodiversity and air quality. The persistence of the problem suggests that existing agricultural, transport and energy policies have not been sufficient to reverse the trend.

Progress, But Not Enough
There is better news on energy. The report says the share of renewable heat is continuing to rise, and that the canton’s target of reaching 100% renewable heat by 2050 remains achievable.
That is one of the clearest positive signals in the report. It suggests that Zurich’s transition away from fossil-fuel heating is moving in the right direction, even if the pace will need to accelerate to meet the 2050 deadline.
The canton’s central conclusion is nuanced: progress is visible in key areas including energy and climate, mobility, nutrition, habitats and the circular economy, but many environmental targets are still not being met. The report explicitly says further action is needed.
That framing matters politically. Zurich is not presenting environmental policy as a success story, but as a mixed record: real movement in some areas, stalled progress in others, and a growing need for more decisive intervention.
Circular Economy Seen As A Lever
The report highlights the circular economy as a way to reduce raw-material consumption while also protecting the climate and Zurich’s scarce land. It also links sustainable nutrition to benefits for both climate and biodiversity.
Environmental problems are increasingly being treated as interconnected rather than separate. A single intervention, such as reducing food waste or promoting reuse, can deliver gains across multiple policy areas at once.
More About Umweltbericht 2026 Report
The Umweltbericht 2026 is aimed at the public, politicians and authorities, and is intended to provide reliable, up-to-date information on the state of the environment. It also includes practical recommendations for municipalities and residents on how they can contribute to environmental protection.
The report was prepared by the Coordination Centre for Environmental Protection (KofU) together with offices of the Building Department and the Mobility Office of the Department of Economic Affairs.
