Why carbon?
Why take action?

5. Why carbon?

6. The case for action: HM Treasury “Infrastructure Carbon Review” 2013
“The Infrastructure Carbon Review sets out a series of actions for government, clients and suppliers to reduce carbon from the construction and operation of the UK’s infrastructure assets, in line with the UK’s climate change commitments.”
The report clearly states:
“Leading clients and their supply chains have already achieved reductions in capital carbon of up to 39 per cent, and 34 per cent in operational carbon. These reductions in carbon have been achieved in association with average reductions in Capex of 22 per cent”
“Reducing carbon reduces costs”

7. The case for capital carbon reduction
Can’t take statement “reducing carbon reduces cost” at face value
To achieve the cost reductions whole life carbon measurement needs to be implemented correctly
Embodied carbon reduction opportunity can only be taken upfront
Once the project is constructed it’s too late

8. Cutting carbon just makes sense
Supports environmental ambitions
Delivers cost reductions
Promotes innovation
Carbon smart
Achieve long-term reductions in carbon emissions through improved energy efficiency, new power sources and modal shift.

9. Carbon measurement: Sources of emission in the rail industry

10. Carbon measurement: Standards and requirements
EN 15978:2011: Sustainability of construction works — Assessment of environmental performance of buildings — Calculation method
EN 15804:2012: Sustainability of construction works — Environmental product declarations — Core rules for the product category of construction products
Environmental Product Declarations (EPDs)
PAS 2050:2011 Version - Product carbon footprint standard from BSI. Linked to Carbon Trust Carbon Reduction Label
World Resources Institute: GHG Protocol for Products
HM Treasury Infrastructure Carbon Review, 2013
PAS 2080 – Carbon Management in Infrastructure – May 2016
BREEAM/CEEQUAL

11. PAS 2080 “Carbon Management in Infrastructure”
PAS = Publicly Available Specification
Released May 2016
Focusses on reducing carbon emissions in infrastructure assets
On a whole life carbon basis (embodied + operational)
Good framework for reduction of rail whole life carbon

13. RSSB Rail Carbon Tool

14. RSSB Rail Carbon Tool: Purpose
Provide accessible, easy to use, central and consistent tool for carbon footprint calculation and analysis to facilitate development of low carbon rail infrastructure.
Free to use
Web based
Flexible format
Enables identification on low carbon options
Enables direct knowledge sharing

15. Carbon calculation and analysis tool for development of low carbon infrastructure: Direct Benefits
Forecast carbon performance of new infrastructure
Identify carbon ‘hot spots’
Drive identification of alternative low carbon options
Compare alternative options
Identify best low carbon solutions
Monitor performance / compare design with as-built

16. Rail Carbon Tool: Direct Benefits
Clear, quick, informative results – maximises carbon reduction potential
Project teams immediately engaged due to transparency and format
Free use – no commercial limitations
Accessible by all and totally secure
Central library of carbon factor and rail data sets
Enables immediate knowledge sharing

17. Rail Carbon Tool: Project and Sustainability Benefits
Extensive project wide sustainability benefits as solutions to carbon reduction, e.g.
Less materials use
Waste reduction
More collaborative working
Lower maintenance
Less lineside neighbour disturbance

18. Key functionality of the tool
Calculation: clear, project specific calculation of carbon footprints, at all levels
Analysis: comparison of multiple options, at all levels with direct data analysis
Graphing
Options evaluation / selection: direct mechanism for
Highlighting carbon hot spots
Identifying performance differences between options
Driving low carbon innovation

19. Data Directly uses existing design, construction and operation data
Materials, transportation, construction, operation, maintenance
All data can be directly shared

20. Applications All infrastructure
Design: value engineering, design development, options selection
Construction performance monitoring and management
Operation and maintenance performance planning and management

21. Scope All life cycle stages PAS 2080 / BS EN 15978
Single limitation: availability of project data and carbon factors

22. Outputs On-screen data and graphs for low carbon innovation
Reporting - PDF outputs for auditing / formal reporting
Publish performance improvement, e.g. CEEQUAL evidence
