The PAS2080 Infrastructure tools are made in compliance with PAS2080 - the world's first specification for managing whole-life carbon in Infrastructure.
We offer two calculation tools:
'PAS 2080 Carbon tool', which reports GWP emissions only
'PAS 2080 for HS2 tool', which reports on a range of environmental indicators and HS2-specific requirements.
Important: The PAS2080:2023 is a new standard that adopts the infrastructure carbon assessment following BS EN 17472:2022. This means that A0 is within the scope for assessment. Please see this instead, if adopting the PAS2080:2023 scheme.
Life-Cycle & Results Scope
The calculation includes the life cycle modules of A1-A5 and B1-B9, C1-C4, and D. The displayed results depend on your purchased PAS2080 tool.
The PAS 2080 carbon tool, reports on Global Warming in t CO2e.
The PAS2080 for HS2 tool, reports on a range of environmental indicators in addition to several circularity indicators.
Data Scope
Both tools allow using of generic data and Type III EPDs. They use CML data and +A2 data cannot be used in PAS2080 yet.
Assessment Scope
There is no fixed scope to which elements need to be included in the assessment, they depend on your project.
Create a project and select the right calculation tool
Create a building project and select your purchased PAS2080 tool as the chosen calculation tool.
Create your first design and set up your LCA parameters.
More information on that is here: Selecting Project Parameters
Input required material data
Fill in your project information in One Click LCA by entering the design either manually or by importing your data (see different import options here; guidance for data import can be found here). If you need help finding the right datasets for your building materials, check our guidance pages here.
Earthworks and mass hauling can be reported under its own tab, material information should not be added to that tab.
When you enter materials to Construction Materials tab, the default impact stage of these inputs is related to is the product stage A. However, if you want to specify the stage of environmental impacts yourself, it is possible to change the 'Impact stage' from the drop down menu. This allows the user to create constructions with maintenance, repair and site work under the same section.
Fill in the Construction site Operations
Fill in your emissions related to the construction process.
Fill in the Use Phase emissions
Fill in your Use Phase emissions, this includes B1-B3, B6-B9. These are annual emissions.
For B2 and B3 fill in your project information in One Click LCA by manually entering data. More information on that is here: Maintenance and Repair Data (B2 & B3)
The PAS2080 tools additionally report on B8 (Other Operational Processes) and B9 (Users Utilisation of Infrastructure), both of which are extension modules from PAS2080. Alike the other use-phase emissions these are annual emissions and have to be filled in manually.
Fill in the Calculation Period
This is required to calculate replacements and end-of-life emissions.
