Tampere tram used 9% of carbon budget in first year, aims for 15% emissions cut
The Pirkkala–Linnainmaa alliance has published its 2025 sustainability report, saying the tramway project used 9% of its planned carbon budget in the first year and aims to cut construction emissions by 15%.
According to a press release published on ePressi, the Pirkkala–Linnainmaa alliance has published its 2025 sustainability report, outlining first-year results and the indicators that will guide construction of the tramway between Pirkkala and Linnainmaa.
The project monitors one key outcome area, responsible and sustainable construction, using three measurable indicators: carbon footprint, a biodiversity index and positive environmental and social actions. The report sets a target of 15% lower construction CO2 emissions than planning estimates. After the first year, the tramway has used 9% of its carbon budget. The interim tally excludes unfinished, carbon-intensive structures such as bridges.
To reduce emissions the work reuses excavated soil more efficiently and optimizes material quantities. It is also deploying lower-carbon materials, including fiber-reinforced concrete and recycled asphalt. Low-carbon solutions will be sought throughout the build, and the final emissions figure will be confirmed when construction is complete.
Biodiversity is tracked with a dedicated index, and the first interim assessment shows improvements since the street design phase. Actions include diversifying plant species, converting lawns into meadows and creating pollinator habitats. Planners are using bee-collected eDNA from pollen to map local plant use and to guide pollinator-friendly planting around the works.
Other measures for people and the environment include relocating trees to new planting sites, reusing felled trunks as deadwood, voluntary water monitoring near bridge works, and planting flowering and useful plants. "Our sustainability goals guide our work, considering both the environment and people," project manager Sari Valjus said. She added that the project aims for transparent monitoring and continued cooperation with stakeholders, and that a strong safety culture is in place to protect workers and nearby residents.
