Motivation • Global supply chains of products and multinational companies ask for consensual set of environmental indicators • Life Cycle Initiative has long-term experience with consensus-finding processes • USETox: toxicity related indicators • Global guidance on LCA database development
Goal of the flagship project • Establish a consensual set of environmental impact category indicators • For use in • Environmental product information schemes • Corporate reporting of multinational companies • International and/or national environmental policies • Common LCA work commissioned by governments and companies

Task 1: Scoping phase • Establish short list of 3 to 4 impact category indicators and themes of first and of second priority • LCIA workshop «Towards development of a global scale LCIA method», Nov. 23, 2012, Yokohama, Japan • LCIA workshop «LCIA methods», May 16-17, 2013, Glasgow
Scoping phase, outcome • 2 sets of 3 to 4 indicators suited for consensus, to be worked on in 1st and 2nd phase of consensus finding • Specific workplan for each individual indicator • List of experts to be involved • Selection criteria of indicators within each topic selected
Tasks 2&3: Consensus finding • Two subsequent phases • 2013-2015 • 2015-2017 • Consensus finding activities covering 3 to 4 indicators/themes per phase • Pellston type workshop at the end of each two years period
Task 4: Dissemination • Establish training material • Organise and hold 5 workshops worldwide

SETAC Glasgow2013 2a. Criteria forpre-selecting impact categories to start with
Cross-cutting Criteria to pre-select impact categories to start from • Environmental relevance • Importance to overall environmental impacts • Scientific validity (how mature is the science; peer reviewed publications) • Potential for consensus • Stakeholder needs • Applicability
SETAC Glasgow2013 2b. Global impact categories Global warming Ozone depletion Ocean acidification
Environmental relevance:Global impact categories Global warming • high relevance Ozone depletion • medium relevance since Montreal protocol successful • N2O may also be relevant now Ocean acidification • One of the 5 main drivers for biodiversity loss set in MEA. drop of pH of 0.1/decade due to CO2 • Rockström et al., 2009 Nature Ridoutt and Pfister 2010 ES&T
Potential for consensus & applicability: Human health emission related categories
Global impact categories • Start with global warming, addressing carbon storage • Perhaps also Ozone depletion, less of a priority • Ocean acidification highly relevant but may be in a second stage?
SETAC Glasgow2013 2c. Human health emission related impact categories Respiratory inorganics Human toxicity Indoor air Photochemical ozone Ionizing radiation Noise
Environmental relevance: Human health Environmental burden of disease (Lim et al., 2013,Lancet)
Scientific validity: Human health emission related categories
Potential for consensus & applicability: Human health emission related categories
Preliminary evaluationHuman health related impact categories
Human health emission relatedcategories: start with: • Respiratory inorganics (including indoor emissions) is a good candidate category for 1st phase, both in term of relevance and reliability/consensus and as a reference category for damage on human health • Human toxicity, (including indoor emissions + ionizing radiation) potentially for 2nd phase building on USEtox
Additional pointsHuman health related impact categories • Further work is needed on noise, risk of injuries, occupational health and effect of diet and physical activity for the LCI & LCIA context • Water related impacts on human health: eventually in interaction with water footprint work
SETAC Glasgow2013 2d. Biodiversity emission related impact categories Acidification Eutrophication Ecotoxicity Ionizing radiation - ecotox impacts Invasive species
Environmental relevance: biodiversity Acidification • One of the 5 main drivers for biodiversity loss set in MEA. • Terrestrial acidificationrelevant for temperate zone • Aquatic very region specific Eutrophication • One of the 5 main drivers for biodiversity loss set in MEA. • Major relevance for agriculture related processes Ecotoxicity • Impacts are limited in case of good practice . May be highly relevant in dev, countries Invasive species • One of the 5 main drivers for biodiversity loss set in MEA • Rockström et al., 2009 Nature Ridoutt and Pfister 2010 ES&T
Scientific validity: Biodiversity emission related categories
Potential for consensus & applicability: Biodiversity emission related categories
Preliminary evaluation of impact categoriesBiodiversity related impact categories
Preliminary evaluation of biodiversity related impact categories • Terrestrial acidification is potentially a good candidate category for 1st phase, especially in term of potential for reliability/consensus. Contribute to frame other biodiversity related categories. • Freshwater (mostly P-related) and Marine (mostly N-related) are very relevant, especially for agricultural related processes and WWTP emissions. May benefit from ongoing research may be more mature in two years perhaps more adequate in a second stage
Additional points • Ecotoxicity: in a second stage for aquatic ecotox building on USEtox consensus process. Further progress needed on terrestrial and marine ecotox • Invasive species: to be framed for LCA
SETAC Glasgow2013 2e. Resource impact categories Biotic depletion Water use Land use Mineral resource Energy resources (Radioactive waste)
Environmental relevanceResource related impact categories Biotic depletion • Marine ecosystems: overfishing Water use • Freshwater biodiversity loss • Global water crisis/food security Land use • Habitat change the major driver of terrestrial biodiversity loss • Link to invasive species Minerals • Planetary boundaries hard to quantify Energy resources • Renewal rate vastly exceeded • Rockström et al., 2009 Nature Ridoutt and Pfister 2010 ES&T
Potential for consensus & applicability: Resource related categories
Preliminary evaluation of resource related impact categories
Resource related categories:Start with: • Energy resources: simple resource indicator might be a good candidate for next phase harmonization • discuss whether water use at the midpoint is suitable (water availability/stress/scarcity indicator) might also be a candidate due to high level of stakeholder demand demonstrated by unique ISO standard.
Resource related categories - Additional points • Further work is needed on biotic depletion (re overfishing). • Lots of ongoing development in water and land use (UNEP/SETAC project groups) • Water and land use impacts overlap to a degree with each other and with other impact categories. • Mineral resources require further framing of the issue to proceed harmonisation
SETAC Glasgow2013 2f. Cross-cutting issues and LCIA framework Guidance on footprint The SETAC-UNEP LCIA framework
So many footprints…what do they mean? Work environmental footprint Food to energy footprint Emission footprint Economic footprint Social footprint Grazing land footprint Job footprint Corruption footprint Environmental footprint ecological footprint Climate footprint • water footprint CO2 footprint Online social footprint GHG footprint Financial footprint carbon footprint Forest footprint GWP footprint Water pollution footprint nitrogen footprint Land use footprint Water availability footprint Waste footprint Methane footprint Chemical footprint Water scarcity footprint Exergy footprint Biodiversity footprint Water stress footprint Human rights footprint Blue water footprint Human footprint Phosphorus footprint Energy footprint Green water footprint Fishing grounds footprint Wind energy footprint Nuclear energy footprint Crop land footprint Grey water footprint Renewable energy footprint Built-up land footprint Solar energy footprint Agricultural land footprint Fossil energy footprint Health footprint Land footprint Poverty footprint Water supply footprint
If our vision is “A world where life cycle approaches are mainstreamed”… …guidance on defining and developing LCA-based footprints is needed • Footprints are the means of communicating LCA information to the mainstream: i.e. remote and non-technical audience • Footprints not grounded in LCA are problematic: • Environmental relevance? • Double counting • How to make sense of multiple footprints • Results may contradict LCA • Footprints are not just new names for existing impact category indicators • Proposal: UNEP/SETAC LCI take a leading role in creating global guidance on LCA-based footprints: • Universal footprint definition • Differentiation from ordinary life cycle impact category indicators • Guidance to support evolution of coherent footprint indicators in support of our vision • Risks of not acting • Reference: Ridoutt and Pfister 2013 Towards an integrated family of footprint indicators.
