All Buses and Heavy Equip­ment Run­ning on Bio­fuels


The Helsinki Metropolitan Area’s buses, heavy equipment and trucks will transition to using waste and residue-based biofuels by 2020. This reduces carbon dioxide and particulate emissions.

When all buses, trucks and heavy equipment in the Helsinki Region shift to biofuels, emission reduction will be 120 000 tonnes CO₂ per year.

80% reduction compared to current CO₂-emissions.

→ Equals annual emissions of nearly 30 000 residents of the Helsinki Region.

Additionally, particulate emissions will reduce by 30%.

What is it all about

Emission reductions

Carbon dioxide emissions are reduced by 80%, or 120 000 tonnes per year.

Better quality of life

Urban citizens are less exposed to air pollution: particulate emissions are reduced by up to 30%.

Business potential

Biofuels can be used in all the world’s cities and ports, for example, which signifies global market potential worth billions of euros.


One of the first urban regions in the world to use 100% waste and residue-based fuels.


A unique public and commercial sector collaboration model based on voluntarism to mitigate climate change.


Smart & Clean and the Climate Leadership Coalition invited all the key actors to the same table and facilitated discussion on setting a common goal. Cooperation between various actors in the Bio100 project enabled a rapid transition to biofuels without the need to revamp vehicles or distribution infrastructure.   

The project adopted ambitious goals that reflect the Helsinki Region’s determination to find quick solutions to mitigate climate change. HSL (Helsinki Regional Transport) can stipulate in all its competitive tenders that routes must be driven using biofuel or electricity. The cities of Espoo and Vantaa joined the project along the way and Posti became an observer member.

The next steps

The goal of buses and commercial vehicles switching 100% to biofuels by the end of 2020 is not likely to be reached, but the goal is proved to be technically possible. Negotiations between operators, HSL and fuel suppliers are ongoing. HSL’s first competitive tender that demands buses run on biofuel or electricity was launched in autumn 2019.

Project goal

The change project’s objective was to facilitate and speed up the transition of HSL’s buses and Helsinki City Construction Services, Stara’s, commercial vehicles to using 100 percent waste and residue-based biofuels by 2020. The project was carried out during 2016–2019.
