Greenhouse gas calculations for the project

Groups: 
  • Design Projects
Category:

Basic

Requirements and Criteria Type: 
  • Contract Terms

Main Objective: 

Significant emissions arise from construction work and the development of new infrastructure. The choice of materials and implementation methods for construction projects is of great importance when it comes to resource consumption, impact on nature and emissions. Increased use of resources/materials and transport often leads to higher emissions. 

The highest emissions can be identified by performing greenhouse gas calculations for the project, including emissions from material consumption. The results of the calculations can then be used to determine the best solutions overall to reduce the climate impact of the project. Emissions calculations show where measures should be implemented to reduce total emissions.

Requirement Specification: 

Greenhouse gas calculations must be used as part of the decision-making basis in the selection of solutions and materials in project management.

The contractor must prepare a greenhouse gas budget for the use of different materials/solutions for phase A1 - A4, from raw material to transport to the construction site. The greenhouse gas calculations must be submitted to the client before deciding which option to choose. 

Documentation of the Requirement Specification: 

Greenhouse gas calculations and documentation of how these have influenced the choice of solutions and materials.

Information about the Requirement Specification: 

The Norwegian Government Agency for Financial Management recommends entering into dialogue with the market concerning this contractual condition, in order to investigate which level contractors are able to deliver at. Consider setting specific requirements concerning emissions reductions that contractors must meet if the market is mature.  

In projects for which it is possible to choose the materials or implementation methods, greenhouse gasemissions calculations should be performed for the different relevant options. In this way, it is possible to reach a decision that has the greatest possible climate effect. The choice of, for example, bridge structures, solutions for the installation of water and waste pipes, etc. influences emissions from resource consumption. As an example, emissions from machinery can be reduced by choosing a zero-excavation solution. The transport distance for materials from factory to construction site, as well as fuel for transport and machinery at the construction site, also influence total emissions.

The results from the greenhouse gas calculations must be viewed in the context of the project’s overall objectives (environment, location, society, etc.) and the impact it has on biodiversity. The client must be clear about its climate objectives in order to highlight the importance of reducing emissions in the project and it would be advantageous for these to be presented during kick-off meetings with the contractor.

We recommend informing the contractor market of any environmental requirements that will apply to future procurements, in order to give them time to prepare to deliver on these.

Requirement Specification: 

Greenhouse gas calculations must be used as part of the decision-making basis in the selection of solutions and materials in project management.

During the concept design project, the contractor will prepare an greenhouse gas budget for phase A1-A5, from raw materials to implementation, in accordance with the Guidelines from Bane NOR, which are in accordance with ISO 14040. The greenhouse gas budget must be submitted to the client before deciding which option to choose.

Documentation of the Requirement Specification: 

Greenhouse gas calculations performed in accordance with guidelines from Bane NOR, including assessments and consequences for the selected solutions and materials.
