Chocolate calculator has encouraged people to cycle and walk

Both decision-makers and residents
are interested in cutting carbon emissions. Thus, a variety of
instruments and incentives have been developed to evaluate and
reduce greenhouse gas emissions from travel and public procurement.

HSL’s Journey Planner (
tells the carbon emissions of a given journey and provides
alternative public transport routes as well as walking and cycling
routes for the journey. The Journey Planner also provides calorie
consumption information to encourage people to walk and cycle. The
calories burned on a journey are expressed as pieces of chocolate.
The so called chocolate calculator can be found on the ‘Further
information’ page of the Journey Planner’s carbon calculator as
well as in the Journey Planner for Cycling ( In a user
survey conducted by HSL, a vast majority of those who had noticed
the calorie consumption information said that the calculator
results had encouraged them to walk and cycle more.

People can evaluate the greenhouse gas emissions of their
weekday (Mon-Fri) journeys using HSL's Jälki calculator ( The
calculator also provides tips for climate-friendly travel.

Calculator helps compare emissions of products 

Carbon calculators have been
developed also for municipalities to help compare products being
procured. The new carbon footprint calculators for public
procurement enable cities and municipalities to estimate the carbon
footprint of IT products, paper, office seats, incontinence
products, and outdoor lighting products as part of their tendering
processes. In addition, general guidelines on how to take
greenhouse gas emissions into account in public procurements, have
been developed.

The carbon footprint calculators for travel and public
procurement were produced as part of Julia 2030
project. Calculation tools were developed also for evaluating and
comparing greenhouse gas emissions from waste management and use of
premises. During the course of the project, 640 new so called
eco-support persons were trained for the municipalities to guide
and encourage their working communities to adopt climate-friendly

The Julia 2030 project was coordinated by Helsinki Region
Environmental Services. Participants in the project included
Helsinki, Espoo, Vantaa, Kauniainen, Kirkkonummi, Kerava, HSL and
the Finnish Environment Institute. The project reinforced the
climate work of the Helsinki region municipalities and joint local
authorities. The three-year project received funding from the EU
LIFE+ program.
