The objective of the Helsinki City is to make Helsinki carbon-neutral by 2030. This goal will be achieved by reducing the greenhouse gas emissions in Helsinki by 80 percent. The remaining 20 per cent will be compensated for by Helsinki taking care of implementing emissions reductions outside the city. The City of Helsinki will also set a goal to attain carbon zero status by 2040. After that the goal will be carbon-negative future.

The City of Helsinki has updated its Carbon Neutral Helsinki Action Plan.  In the updated plan, special attention has been paid to the effectiveness of the measures. The measures will be updated annually in the future. You can follow the implementation of the program’s measures and emission reductions here.

In 2022, total greenhouse gas emissions from Helsinki were about 25 percent lower than in 1990. Per capita emissions were 44 percent lower than 1990. Total energy consumption in the urban area remained unchanged despite the increase in population, which is related to improving energy efficiency. Carbon neutral energy accounted for 37% of the production in the city area.

The climate work is versatile, e.g. during 2020 the City of Helsinki:

  • looked for solutions to Helsinki’s heating challenge through a competitionRegional geothermal heat solutions are promoted
  • implemented climate targets for Helsinki’s building stock ambitiously
  • took low-carbon principles into account in area construction
  • reduces emissions from ground preparation prior to construction
  • developed worksites to become emission-free
  • had many development projects underway in building construction
  • reduced traffic emissions by many means, and
  • had a lot of projects speed up development work.

The City can promote a carbon-neutral Helsinki with various steering measures. The City can also enable, encourage and regulate emissions reductions, for example in the following manners:

  • through collaboration with companies
  • by offering test platforms for new low-emission trials
  • by steering operations through land use planning and plot assignments
  • through traffic planning, such as the promotion of bicycling and walking
  • by directing construction
  • through communication and interaction
  • through education
  • by promoting public transport
  • by supporting low-emission vehicles
  • through procurements and investments


The City In A Changing World

Boundary Conditions of a Finite Planet for Planning a Carbon-negative City

Environmental Report 2021

The year 2021 was meaningful for both the climate and the environment in Helsinki. We decided on the new City Strategy, which will set the bar higher for our carbon neutrality objectives, set ambitious policies for ensuring biodiversity and requires us to pay more attention to reconciling housing construction and natural values. Helsinki brought its carbon neutrality target forward to 2030. The new City Strategy also specifies that the City will have a zero-carbon target for 2040. The practical decisions that we make during this council period of office will be crucial for achieving the objectives set.

Summary of an Expert Survey

Roadmap for Circular and Sharing Economy

At the moment, our society relies heavily on linear economy: products are manufactured, consumed and thrown away. This has proved unsustainable in terms of the climate, use of resources, economy and people’s well-being. Helsinki has recognised the significance of circular and sharing economy for solving major sustainability challenges. For the first time, circular economy is one of the themes in the City’s environmental policy, which is currently being updated. One of the long-term goals in the policy draft is that the City will operate in a carbon-neutral circular economy by 2050. In this economy, natural resources will be used sustainably, and the value of products and materials will be maintained in the circulation for as long as possible. This roadmap also supports the progress towards these goals.

Helsinki's Climate Change Adaptation Policies 2019-2025

Helsinki’s climate change adaptation policies for 2019–2025 are a strategic plan, with which the City can adapt to the changing climate. With these policies, the City intends to mitigate the harmful effects that climate change has on society’s effective functioning, economy, nature and peoples’ everyday lives, and to take advantage of any benefits brought on by the changing climate.

A Sustainability Rating System for Businesses

A pilot of the Think Sustainably initiative, on the MyHelsinki website, businesses are certified as sustainable according to a matrix of criteria. The rating system aims to make it easier to for people to make sustainable choices and encourages service providers to become more sustainable, faster.

Construction Underway for Expansion of Underground District Heating System

The Helsinki energy company, Helen is building Finland’s largest underground heat storage facility in former oil storage caves. The facility will reduce Helen’s carbon dioxide emissions by 21,000 tonnes and will be connected to the existing district heating network.
