Environmental measures strengthen the impact of public transport

Benefits to public health and reductions in local and global pollution are the key environmental advantages of public transport. Public transport is a prerequisite for the renewable society of the future. One of Ruter's important and ambitious goals is for public transport to run only on renewable energy by 2020.

Fossil free 2020

By the end of 2020, all public transport should run on renewable energy only. The switch to renewable energy will at the same time result in lower local emissions, greater energy efficiency and less noise from public transport. The tram and metro are already running on certified, renewable electricity, while buses and boats mainly run on fossil fuel. Buses have the largest overall emissions of public transport, but emissions are highest for boats when calculated per passenger kilometre.

In 2020, the buses will run exclusively on renewable energy. In 2025 the entire bus fleet will be replaced with zero and low-emission technology.Ruter has adopted a target for the bus fleet for 2025 based on an assessment of the technology and fuels that are suitable and desirable.The target sets the level of ambition and provides direction for a restructuring of the bus fleet in the region. In 2020, the buses will run exclusively on renewable energy. In 2025 the entire bus fleet will be replaced with zero and low-emission technology. We assume that electricity will increasingly replace biofuel as the energy carrier after 2025.

Such a development entails:

  • Ambitiousness on behalf of the environment, where the renewable target is reached in 2020 as part of a more long-term development towards 2025
  • That nearly a third of the bus fleet is entirely electric in 2025 (battery and fuel cell)
  • In 2020, a significant number of battery-powered electric buses will be deployed in the centre of Oslo, with fast charging at underway stops.
  • Testing will commence at an earlier stage.
  • Major push for biogas from around 2020, and almost 500 buses running on biogas in 2025.

The ferries on the Oslo fjord should operate on renewable energy in 2020. Retrofitting of existing boats may be a solution in some instances, but on other routes new vessels will be introduced, with new and innovative solutions. The size of the boats, the short routes and low speeds may make the island ferries a suitable candidate for battery-electric propulsion. High energy use means that zero-emission solutions are farther away for high-speed craft.

An investment in health and the environment

In 2025, the greenhouse gas emissions from Ruter’s bus operations may be reduced by 80-90 per cent.Based on current forecasts, we assume that the switch in technology and fuel in the bus fleet could result in added costs for bus operations of around 2-10 per cent per year in 2025, compared to the existing bus fleet. The technology shift must be financed without reducing Ruter’s ability to meet the growth in demand for individual transport.

In 2025, the greenhouse gas emissions from Ruter’s bus operations may be reduced by 80-90 per cent. Further electrification with renewable energy will lead to the near elimination of greenhouse gas emissions from public transport.

As early as 2025, a third of the region’s buses may run with no emissions and with a low noise level on all or part of the routes. A large proportion of these buses will operate in the city centres. This means better air quality, less noise and better health for the population.

Strengthening the impact of public transport

With renewable energy and zero-emission solutions, current emissions from public transport will be lowered significantly by 2030. Efficient use of resources may then be the most important environmental challenge.

The switch will contribute to a better public transport service in the region, with innovative solutions, and reliable, energy efficient and quiet vehicles. The legitimacy and competitiveness of public transport will thus be enhanced.

Ruter must adopt new technology

Ruter and other administration companies collaborate internationally to ensure that public transport facilitates a market for new technology that producers of buses and boats can supply. Among other things, Ruter wants to look at the option of collaborating with other administratione companies, for instance in Paris and London, on the procurement of electric buses with various technological solutions.
