    Assessing the sustainability of building materials Assessing the sustainability of building materials Presentation Transcript

    • Format 1 2 3 4 5 Research Question Criteria for the Selection of Methodologies Selected Methodologies Discussion The Sustainable Building Materials Index
    • Research question • Can an objective way of measuring, and representing, the key social and economic sustainability impacts related to the building products be developed, in order to enable building products to be compared?
    • Theoretical framework • What is meant by social and economic sustainability impacts? ...improving the quality of human life while living within the carrying capacity of supporting eco-systems. (IUCN/UNEP/WWF,1991) Quantified definition the achievement of an Ecological Footprint of less than 1.8 global hectares per person and the achievement of a Human Development Index value of above 0.8 (World Wild Life Fund, 2006).
    • Review criteria for methodologies A. Do the methodologies enable the assessment of building products, and comparisons between building products, to be made? B. Do the methodologies focus on measurement of key social and economic aspects related to sustainability?
    • Methodologies
    • Selected Methodologies A. Global Reporting Initiative B. ISO 26000 Guidance on Social Responsibility C. Guidelines for Social Lifecycle Assessment of Products
    • Selected methodologies A. Global Reporting Initiative B. ISO 26000 Guidance on Social Responsibility C. Guidelines for Social Lifecycle Assessment of Products
    • Global Reporting Initiative • • • Developed by the Global Reporting Initiative ‘a trusted and credible framework for sustainability reporting’. [ report content]... made by considering..organization’s purpose and experience, ..expectations and interests of the organization’s stakeholders.
    • GRI assessment criteria Economic performance Market presence Indirect economic impacts Materials Energy Water Biodiversity Emissions, effluent and waste Products and services Compliance Transport Employment Labour / management relations Occupational health and safety Training and education Diversity and equal opportunities Equal remuneration for woman and man Investment and procurement practices Non discrimination Freedom of association and collective bargaining Child labour Prevention of forced and compulsory labour Security practices Indigenous rights Local communities Corruption Public policy Anti-competitive behaviour Compliance Customer health and safety Product and services labelling Marketing and communication Customer privacy Compliance
    • Application Levels for GRI reports
    • ISO 26000 Guidance on Social Responsibility • • • • Developed by International Standards Organisation (ISO) ...provide guidance on the underlying principles of social responsibility ...integrate socially responsible behaviour into the organization Guidance - not to be used for certification
    • ISO assessment criteria Human rights Labour practices The environment Fair operating practices Consumer issues Community involvement and development
    • Overview of ISO 26000
    • Guidelines for Social Lifecycle Assessment of Products • Developed by United Nations Environmental Programme • Increase decision-makers’ awareness of more sustainable life cycle stages. Provide holistic assessments of the implications of a product’s life cycle for the environment and the society. Offer guidance to reduce environmental degradation increase the environmental, economic and social benefits • •
    • GSLAP assessment criteria Human rights Working conditions Health and safety Cultural heritage Governance Social and economic repercussions
    • Social impact assessment system from categories to unit of measurement
    • Example summary of S-LCA for considered stakeholder groups
    • Discussion • • • • GRI, ISO and GSLAP methodologies are relevant and have useful concepts that can be applied to the CBA project. None of these methodologies can be readily be applied to compare social and economic impacts of building products in South Africa The GSLAP methodology comes closest to this requirements. It will however require standardisation to support comparability. Worth developing an SBMI
