The B.Green project aimed to develop a model for digital and participatory urban planning that promotes the pre-planning of multifunctional green infrastructure solutions in the Baltic Sea region. The project has piloted green solutions with residents and experts in Helsinki and Tallinn.

Green infrastructure solutions are essential factors in climate change adaptation and reaching carbon neutrality goals in cities. The goal of B.Green was to find innovative approaches to support the pre-planning and implementation of new, multifunctional green infrastructure solutions within the urban planning context in the Baltic Sea region.

The pilots were carried out in Kalasatama district in Helsinki and in Pollinator Highway in Tallinn .

Pollinator Highway

The Pollinator Highway is a meadow-like natural environment rich in species, a green corridor and a space for people to move through six city districts in Tallinn. The Pollinator Highway runs along a former railway embankment and today’s high-voltage line corridor. When the high-voltage lines are moved into the underground cable, the potential for a city-wide linear park is released.

Climate Sensors in Tallinn

Urban environments experience heavier heat stress than natural environments because buildings, pavements and parking lots create urban heat islands. To cope with the increasing heat during climate warming, more green and blue spaces are needed in cities – parks, trees along the pavements, and permeable soils.

In 2022, 18 climate sensors were installed in Tallinn for the B.Green project. These sensors will measure the temperature, relative humidity and precipitation in different parts of the city.

The measurements will give an understanding of how heat waves affect Tallinn and where green spaces could help create a more livable environment.

These 18 sensors provide weather  information in real time and everyone interested can also see the weather forecast for the following hours and days in different locations.

More information about the urban weather sensor methodology can be found here .

B.Green Handbook

The aim of the handbook is to guide urban planners and other stakeholders interested in promoting green infrastructure planning. It introduces digital and participatory tools as solutions that can help planners overcome some of the major challenges when planning green infrastructure. These tools are presented holistically in the context of the planning process. These tools and accompanying processes have been developed by the two capital cities – Helsinki and Tallinn – in the B.Green project. These are supplemented with experiences from various cities in the Central Baltic region.

The handbook is set up to provide multiple topics as entry points: climate resilience, planning challenges, digital tools, participatory methods and planning phases.

Residents' Survey

In 2021 a survey was organized by the B.Green project. The goal of the survey was to map the attitudes and insights of Helsinki and Tallinn residents related to green infrastructure planning and participatory methods. It focused on two related projects: Kalasatama in Helsinki and the Pollinator Highway in Tallinn.

Results of the survey

Tallinn, the capital of Estonia, will become the next European Green Capital in 2023. What makes Tallinn green, and is that enough? Stockholm Environmental Institute Tallinn Centre intern Emile Neimry takes a look, analysing the most recent climate data measured in Tallinn.
