Green Guide to Specification Update Briefing Note 8: Data Requirements

Purpose of this note

• To set out the historical background to environmental Life Cycle Assessment (LCA) data collection at BRE,

• To provide information about the data currently held by BRE, • To list the groups that have already expressed interest in updating their

Environmental Profiles and • To identify potential remaining gaps in the provision of new data for the next

edition of the Green Guide. In this respect industry groups are invited to help fill the gaps in the data.

Background The current Green Guides to Specification are based on LCA data collected by BRE. This data has been populated from a variety of sources:

• The principal route has been generic data collected by UK industry Trade Associations (TA) and processed by BRE. The majority of TA’s provided information as part of a DETR funded “Environmental Profiles of Construction Products Methodology and Data Collection” project which ran from 1995 -1999 1. Where released by the TA, this data is available free of charge on the BRE Environmental Profiles website 2.

• Further industry groups have subsequently worked with BRE on a

consultancy basis to collect generic Environmental Profiles LCA data for their products. Again, where released by the TA, this data is also available free of charge on the BRE Environmental Profiles website.

• In addition to this, individual companies have worked with BRE through BRE

Certification to obtain certificated Environmental Profiles. All of this data is freely available on the BRE Environmental Profiles website.

• Where data has not been provided through the Environmental Profiles

project, BRE have used a database of LCA data based on best available data sources generated at the time of the original DETR funded project. This information will be reviewed for the new Green Guides.

Current Data A series of Tables have been prepared for each of the major product groups represented in the Green Guides. The Tables present data:

• Age • Geography • Source • Representativeness • LCA methodology used

Material and product groups include: Table 1: Ceramic products......................................................................................... 6 Table 2: Flooring ....................................................................................................... 7 Table 3: Metals .......................................................................................................... 9 Table 4: Quarried Materials ..................................................................................... 11 Table 5: Insulation ................................................................................................... 13 Table 7: Timber and other biobased products.......................................................... 15 Table 8: Paints ........................................................................................................ 16 Table 9: Cementious and Concrete Products .......................................................... 18 Table 10: Other materials ........................................................................................ 20 The quality of data varies. Some data is UK-specific, representative of the sector and prepared within the last five years, whilst some has been derived from an estimate based on an extrapolation from a similar product. A data quality hierarchy is discussed below. All data for commonly used construction products in the Green Guides has met minimum quality standards as presented in the data quality hierarchy. Data quality is therefore good having been derived from industry-representative, UK or European sources. However, it is typically now 5-8 years old and can therefore benefit from an update. Updating the data Four main approaches have been identified to update the information as part of the Green Guide update: New Trade Association data As part of the project, we hope that TA will take the opportunity to produce up-to-date Environmental Profiles to provide the most accurate and representative picture of products from their sector. A consultancy fee is required for this work, which receives no external funding. However, if such data is not forthcoming, we intend to review the LCA sources described below to update the best available data.

Existing Trade Association data Where TA are aware of existing LCA studies, we encourage them to make a copy available to us for review. We encourage TA to maintain a dialogue with us to ensure that LCA data is being accurately adapted (where necessary) to be used within the Green Guide. A consultancy fee is required to cover this aspect of our involvement.

LCA databases • Eco-Invent – produced for the Swiss Government – www.ecoinvent.ch • Boustead – produced by a UK based LCA consultancy – www.boustead-

consulting.co.uk • IVAM – produced by the University of Amsterdam – www.ivam.nl • Idemat – produced by TU Delft – www.io.tudelft.nl/research/

dfs/idemat/Onl_db/od_frame.htm

Other Sources In addition, we will conduct searches for LCA studies, for example through the International Journal of LCA, the Simapro discussion e-list, and LCA search tools such as http://www.pre.nl/lcasearch/. Data Quality To provide users with confidence in the data sources used in the Green Guide, a data quality hierarchy will be established. This is still in progress, but the general order of ranking will be:

1. Industry-representative data, UK-specific 2. Industry-representative data, European/International 3. Manufacturer-specific data, UK-specific 4. Manufacturer-specific data, European/International 5. Best Available data. This data may be derived from unpublished sources, or

be an estimate based on an extrapolation from a similar product. We will review data in terms of the following aspects and determine a protocol for overall categorisation into the classes 1-5 above. This process will be based on the following parameters:

QUALITY GOOD ACCEPTABLE POOR

Age From 2000 onward From 1995-1999 From 1990-1994 Geography UK* Europe Rest of World Source Trade Association Single Manufacturer Single Manufacturer Representativeness Over 50% of industry 20-50% of industry Less than 20% of

industry LCA Practitioner LCA verified by 3rd

Party Non-verified Student, Non-verified

Methodology Transparent and including all inputs and outputs

Some transparency or some aspects missing (eg waste)

No transparency, unclear methodology or significant aspects missing (eg emissions)

*UK specific data is generally considered to be most acceptable. The exception here is for raw materials such as steel or plastics which are commonly sourced internationally. In creating new generic data sets, we may combine more than one dataset where no one dataset meets all the “Acceptable” criteria. The overall environmental impact of a product may be adjusted by a particular factor where it fails to meet any of the criteria, to take account of the uncertainty arising with reduction in data quality. The Table below shows BRE’s suggested adjustments,

though these may be reviewed for particular datasets based on submissions by TA or other interested bodies.

QUALITY ACCEPTABLE INADEQUATE POOR Age No adjustment No adjustment –

manufacturing efficiency will have improved over the time period therefore no further adjustment is required

Methodology Data adapted to BRE Methodology and worst case estimate for missing data

Data adapted to BRE Methodology and worst case estimate for missing data

These adjustments are necessary to overcome potential inaccuracy in low quality data, to ensure that UK generic industry is well represented and that those organisations who undertake Environmental Profiles and prepare high quality data sets are not disadvantaged. New Data The following sectors are already in discussion with BRE regarding the potential provision of new data for Environmental Profiles.

Sector Company/Trade Association Concrete Blocks Concrete Block Association (in progress) Cement British Cement Association Bricks Brick Development Association Steel Corus and the Steel Construction Institute Carpets European Carpet and Rug Assoc. (ECRA) – data from GUT

(Gemeinschaft Umweltfreundlicher Teppichboden) PVC Windows British Plastics Federation EPS insulation British Plastics Federation EPS Construction Group PVC and other plastics British Plastics Federation (from Plastics Europe) Aluminium CAB and ALFED Roofing Membranes Single Ply Roofing Association Composites NetComposites GGBS Cementitious Slag Manufacturers Association Resilient flooring UK Resilient Flooring Association Mineral wool insulation Eurisol

Invitation Further manufacturers and TA are also welcome to prepare data sets for the next Green Guide. In this respect BRE would like to formally invite industry representatives to part take in Environmental Profile development. Areas where BRE particularly require participation are identified within the Tables below under the heading “new data required for”. The process for creating an Environmental Profile is:

• Complete an Environmental Profiles application form 3 • BRE prepare quotation. Costs will vary according to number of sites and

complexity of process • Agree Timelines for both industry and BRE re data provision and analysis • Industry gathers production data from the preceding year and completes

an Environmental Profile Questionnaire • BRE process data and provide industry with Environmental Profile

In order to meet the programme requirements of the Green Guide update programme, a timetable for involvement has been established.

Action Required by Trade Association/Company Deadline Notify BRE of intention to provide data by 30th May Meet with BRE and scope nature of data collection and cost provision of Environmental Profile

by 24rd June

All data to be collected and submitted to BRE by 28th October We recognise that collecting the data required is more or less challenging for different industries and that it may not be possible for every sector or company to meet this timeline. We propose a solution to this. The next editions of the Green Guide will be electronic as well as paper based and it is expected that users will quickly become accustomed to using the On-Line Green Guide “bulletin board”. This will feature new specifications and new ratings for existing specifications. In this way, we can provide a compromise position between delaying the publication of the Guide for a number of months to enable most data sets to be updated, and potentially delaying this update by a year or more to enable all organisations to be updated before re-publication. To meet individual sector needs, it will be necessary for BRE to have discussions with that sector. These meetings have already begun and we welcome further enquiries.
