The carbon dioxide emissions from car traffic are decreasing, but for heavy duty traffic, the trend does not look as positive - the emissions of carbon dioxide are increasing due to a growing amount of transports. In the City of Stockholm, heavy traffic accounts for 4 per cent of the traffic measured as vehicle-kilometres, but for 23 per cent of the emissions (2013). In 2010, the emissions of greenhouse gases from heavy vehicles increased by 44 per cent compared with 1990. At the same time, the share of clean trucks was negligible. Something had to be done to break this negative trend
Facilitating the introduction of CleanTruck
CleanTruck was running between 2010 and 2014 and was the first project of its kind for heavy duty trucks. The aim was to hasten and facilitate the
introduction of trucks with environmentally adapted technology. To get there, the project offered grants to interested distributors to compensate for the clean trucks being more expensive, and to OKQ8/IDS and AGA for establishing infrastructure. Focus was on heavy duty vehicles in city traffic, and only technologies that were partially unproven could be included in the project.

Three different kinds of CleanTruck technologies
The project included three different truck technologies all of which were on the threshold of market introduction when the project began in
- Ethanol ED95
- Methane diesel (i.e. methane gas and diesel)
- Hybrid electric trucks
Cryo Tech transport cooling
The Liquid Carbon Dioxide (LIC) technology was already on the market when CleanTruck began although on a small scale. The project offered grants for the incremental costs to introduce of the technology.
Nitrogen gas in tyres
Nitrogen gas in tyres was another technology included in CleanTruck. With the right tyre pressure, fuel consumption is reduced. In addition, wear on the tyres is reduced substantially, which means lower operating costs for the distributor.
The driver affects fuel consumption to a high degree through his or her style of driving. CleanTruck included knowledge support as well as cost reimbursement for continued training in economical driving for participating companies.
Participating transport companies that invested in environmental trucks were offered added expense compensation to make up for the more costly technology. At the same time, the companies committed to participate in the project’s evaluation and to help distribute information to companies following suit.
An important link
CleanTruck constituted an important link between research and development and a full-scale introduction of new, environmentally adapted technologies, new filling stations for alternative fuels, filling stations for LIC and equipment for the inflation of tyres with nitrogen gas. The aim of the project was to demonstrate how carbon dioxide emissions and other emissions from the goods transport sector can be reduced by introducing new technologies in heavy vehicles for urban distribution. The project’s experiences should be of sufficient interest to inspire more efforts of a similar nature and imitators.
CleanTruck was run by three parties: City of Stockholm, AGA and OKQ8/IDS
The Environmental and Health Administration of the City of Stockholm coordinated the project. CleanTruck was financed with the support of the European Union environmental programme LIFE+, Vinnova and the Swedish Energy Agency.
The Environmental & Health Administration of the City of Stockholm was responsible for project management. AGA was responsible for the building Stockholm's first filling station for liquid and compressed gas as well as filling stations for LIC and nitrogen gas. OKQ8/IDS invested in the world's first public fuel facility for ethanol diesel ED95.
18 private transport companies participated in the project. In total, the participating companies purchased 50 CleanTrucks and five refrigeration units for LIC. The trucks were used for waste collection, construction and goods and product distribution in Stockholm.
