Greenhouse gas calculations for the project

Groups: 
  • Design-Build Contracts
Category: 
  • Materials

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. Greenhouse gas calculations show where measures should be implemented to reduce total emissions.

Requirement Specification: 

The contractor must prepare a greenhouse gas budget for project planning and climate accounts for the selected solution for phase A1 - A4 (in accordance with EN 15804), from raw material to transport to the construction site.

Documentation of the Requirement Specification: 

Greenhouse gas calculations, including assessments and consequences for the selected 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 order to identify the solution with 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. By including emissions from the use of the development (advanced level) in the emissions calculations, it becomes apparent that products with a long service life reduce the need for maintenance/replacements and associated emissions.

Figure 2: Overview of the different phases in emissions calculations.

The results from the greenhouse gas emissions 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 that this will form the basis when choosing solutions.

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: 

During the project planning phase, the contractor must prepare a greenhouse gas budget for phase A1-A3, A4, A5, B1-B6 (in accordance with  EN 15804), in accordance with the guidelines from Bane NOR. How the greenhouse gas calculations have influenced the choice of solutions and materials in the project must be shown in the decision-making basis for the selection of solutions and materials.

If a greenhouse gasemissions budget is available from project planning, this budget must be enclosed as an appendix to the invitation to tender and must also be used as a basis for the updated accounts.

Greenhouse gas calculations must be implemented in project management and will be used to influence actual choices and solutions in the project.

The final accounts must be submitted in connection with handover of the project.

Documentation of the Requirement Specification: 

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