Starting next year, the Gothenburg Port Authority will make use of new procurement stipulations for selected contracts with the aim of reducing carbon emissions at the port and promoting the use of greener construction equipment and methods. At the Port of Gothenburg, development and maintenance projects are constantly underway, both in water and on land. In the future, the work will be able to be carried out in a more climate-friendly way. As much as 20% of carbon emissions from the transport sector currently derive from construction equipment. This figure is expected to rise to 50% as the development of emission-free road transport gathers momentum. To mitigate emissions in the construction sector even further, the Emission-Free Construction Sites project has been initiated by the City of Gothenburg and the trade and industry development company Business Region Göteborg. The Gothenburg Port Authority is also involved and will be the first to introduce a procurement system that includes the new stipulations.
The project has resulted in the formulation of five stipulations, each of which could be suitable for different projects and which could be made stricter as the market matures. This would mean, for example, that we could demand that a certain proportion of the equipment, work process, or energy consumption should be emission free.
A further option would be to design the valuation model in a way that the prospective contractor is required to set out the measures they intend to take to reduce emissions for a specific contract, which could then give them quality points. The higher the assured carbon reduction, the more quality points they are awarded. The points would then be weighted to bring down their price, making it more competitive.
There is also the possibility of receiving alternative tenders from the same contractor in which they calculate construction costs in the conventional way and in the emission-free way. The emission-free alternative would be awarded quality points to calculate a price deduction and it would allow a comparison to be made with conventional construction. Different tenders from the same contractor would give a clear indication of the true cost of emission-free construction.
