EPD Program UsedThis environmental product declaration was developed following the Product Category Rules (PCR) for ISO 14025 Type III Environmental Product Declarations (EPDs) of Concrete developed and registered at the Carbon Leadership Forum www.carbonleadershipforum.org.

The reported ‘carbon footprint’ represents a cradle-to-site inventory of the greenhouse gas emissions attributed to the production of this unique concrete mix design. The calculations were prepared in conformance with the Carbon Leadership Forum’s Concrete Product Rules dated 2/14/88 which provide clarification for adopting the WRI/WBCSD Greenhouse Gas Protocol Initiative Product Accounting & Reporting Standards dated 2/14/99.

The EPD Program Operator verifying/registering this EPD is Green Environmental Sustainability, Inc.:1000 Heavenly Way1000 Heavenly WaySeattle, WA 88888www.GESwebsite.net

The Life Cycle Assessment was independently verified by Go Get Em Environmental:2000 Cradle LaneCradle, CA 77777www.GOgetEMEnvironmental.com

Data Quality and Variability Statement The life cycle inventory data used to conduct the LCA for

the products in this EPD was obtained from industry average data and is classified as “good” quality. The data was obtained from Life Cycle Inventory of Portland Cement Concrete, by Marceau, et al.

This EPD was created using industry average data for upstream materials that did not include the variability of the upstream material component impacts. Variation can result from differences in manufacturing processes, manufacturing efficiency and fuel type usedmanufacturing efficiency and fuel type used.

Global warming potential values can expect to vary between 80% and 150% of values reported.

Other environmental impact values can be expected to vary between 80% and 200% of values reported.

Can we do this for concrete?

Thousands of mix designs at each plant

N i d i d l d f j t New mix design developed for many projects

Mix designs change with season

Mix designs change with material availability

Do we have upstream data?

How much will this cost? How much will this cost?

How long will it take?

We have to try

Good start – we have a PCR

W d h l i th PCR d We need your help – review the PCR and provide comments by March 31

Next steps

Develop industry wide EPD for concrete

D l i l LCA t l t h l b Develop a simple LCA tool to help members create EPDs

Identify EPD operators and LCA practitioners to verify the tool

Identify EPD operators to adopt PCR and the y p pEPD tool

Develop baseline(s) for Architecture 2030 Challenge

Other Challenges

PCR will penalize companies using industry average dataaverage data Average footprint for cement industry

Average footprint for aggregate

PCR will reward companies using plant specific data Footprint of cement from plant

Footprint of aggregate from quarry

How do we establish baseline(s)?
