Transcription

1 Ecosystem Service Indicators and the GRI Emerging philosophy and case studies of associated corporate sustainability reporting Tristan Tyrrell International Symposium 2011: Evaluating Biodiversity 17 February 2011 United Nations Environment Programme World Conservation Monitoring Centre

2 UNEP-WCMC Biodiversity assessment and biodiversity policy support arm of UNEP In operation for 30 years Provides objective, scientifically rigorous products and services Interprets and analyses data and makes the results available to both national and international decision makers and businesses.

3 Global Reporting Initiative Pioneered the world s most widely used sustainability reporting framework Core goals include the mainstreaming of disclosure on environmental, social and governance performance GRI's Reporting Framework developed through a consensus-seeking, multi-stakeholder process

4 What is an indicator? In common use today, e.g., level of unemployment or GDP Can be simple measures or multiple indicators can be combined to form a composite index Purpose-dependent Always need some analysis and interpretation Net change in forest area in regions of the world (MA 2005)

5 What is an indicator? The GRI has five basic criteria for indicator design: Relevance Comparability Unbiased/Neutral Clarity Feasibility

6 Materials Energy Water Biodiversity Emissions, effluents, and waste 6 Transport GRI Performance Indicators Selec%on of GRI Performance Indicators: Environment Materials used by weight or volume Energy consump8on by primary energy source Renewable energy- based products and services Total water withdrawal by source Water sources significantly affected by withdrawal of water Loca8on and size of land owned, leased, managed in, or adjacent to, protected areas/high biodiversity value Significant impacts of ac8vi8es, products and services on biodiversity Habitats protected or restored Number of IUCN Red List species and na8onal conserva8on list species Total (in)direct greenhouse gas emissions Other relevant indirect greenhouse gas emissions Emissions of ozone- deple8ng substances NO X, SO X and other significant air emissions Total water discharge Total weight of waste by type/disposal method Total number and volume of significant spills Weight of transported, imported, exported or treated waste deemed hazardous Iden8ty, size, protected status, and biodiversity value of water bodies and related habitats significantly affected by discharges of water and runoff Significant impacts of transpor8ng products and other goods and materials

7 Ecosystem Services Millennium Ecosystem Assessment (2005) classified ecosystem services as: supporting (e.g. soil formation) regulating (e.g. water retention) provisioning (e.g. food) cultural (e.g. recreation) Concept continually evolving More recent frameworks differentiate between actual benefit derived ( stock ) and those necessary for delivering a service ( flow )

8 Ecosystem condition and biodiversity - e.g. soil organic matter, forest disease prevalence, water quality Ecosystem function - e.g. Ecosystem Services water purification and climate regulation, or primary productivity Service provision - e.g. timber produced, water available, or coastal defences present Realised benefits - e.g. timber utilized, water consumed, infrastructure or land protected

9 Company interactions with ES Dependencies Companies depend upon a large array of goods and services provided by ecosystems Direct dependence natural resources that are used by company (e.g. water use) Indirect or secondary dependence e.g. oceanic nutrient cycling essential to fish productivity

10 Company interactions with ES Impacts A company can have a range of impacts when the stocks and/or flows of ES Direct impact - e.g. excessive water use, pollution, carbon emissions Indirect or secondary impact - e.g. water use causing a change in the river flow; immigration to certain areas as a result of the availability of jobs or roads Cumulative impact e.g. global climate change as a result of cumulative GHG emissions

11 Company interactions with ES Impacts Linear change e.g. water quality declines with an increased level of effluent output. Non-linear change increases in pressure from a company cause changes to the stock or flow of ES once a threshold of pressure is reached

12 Company interactions with ES Impacts and dependency relationships are not mutually exclusive Many direct impacts will lead to indirect impacts All of these can occur over different geographical and temporal scales Can occur throughout the supply chain from production and manufacturing through to consumption and disposal

13 Company interactions with ES 1. Company pressures on the state of ecosystems 2. Pressures of other actors (and/or natural causes of change) on the state of ecosystems 3. Combined pressures of the company and other actors on the state of ecosystems 4a. Potential impact a company will have on ES 4b. Actual impact on the state of ecosystems

14 Company interactions with ES 5. Dependencies the company has on ES 6. Beneficiaries and the benefits they receive from the ES impacted or depended upon by the company 7. Effect of the company s management response to mitigate its pressure on the system 8. Effect of other beneficiaries responses to mitigate their pressures on the system

15 Existing corporate approaches to ES Corporate Ecosystems Services Review Methodology to identify connections between impact & dependence, and potential risks or opportunities. Five steps: 1. Select scope of ESR 2. Identify priority ES the ones most relevant to corporate performance in the context of dependency and impact 3. Analyze conditions and trends in priority services, as well as the drivers of these trends 4. Identify business risks and opportunities that might arise due to trends in the priority ES 5. Develop strategies for managing the risks and opportunities

16 Existing corporate approaches to ES Rio Tinto Developing a project entitled Natural Capital Investigate the business case and methodologies around designing and implementing ecosystem service offsets and investments in non operational, land based assets. Collaboration with the IUCN, utilising tools from WBCSD, WRI and the BSR In Utah, created and sold wetland credits as part of our Inland Sea Shorebird Reserve project. In Madagascar, exploring developing ecosystem service credits around water and biodiversity at a number of conservation management sites.

19 Impacts Challenges of indicator development Requires a broad understanding of ecological and social aspects Measuring changes in ES is complex and may require expert knowledge that needs to be acquired externally Aggregating impact data problematic to show links in operation-level data to local state & benefit changes Changes in ES may be the result of natural changes and may be caused by a combination of different pressures from a combination of stakeholders.

20 Impacts Proxy indicators Use information on the condition of ES gathered by others Assess the risk that significant impacts may happen Use (quantitative or qualitative) information from local/ regional experts and local/regional stakeholders to decide on the severity of potential, perceived and/or actual impacts

21 Dependencies Challenges of indicator development A company may not be familiar with all pressures it creates on an ecosystem Data availability, complexity, etc. It is often difficult to know how each pressure will impact ES due to trade-offs. Measuring ES dependencies alone may not detect emerging issues and trends until it is too late to address them

22 Dependencies Proxy indicators Focus on a limited number of company pressures on ES and take only the most significant ones into account in reporting Define a minimum set of common indicators (pressure indicators relevant in most situations)

23 Responses Challenges of indicator development A company s response should match the company s main impacts on the condition of the ecosystem and ES Some concepts, such as compensation, are still in their infancy, and if reported will raise many questions. Obtaining information on the response to pressures on the system initiated by other actors.

24 Responses Proxy indicators Report on responses that seek to minimize any pressures that have the potential to lead to an impact Report on responses that aim to secure a future supply of services

25 Current status of project and next steps Two discussion papers produced, with input from an advisory group Side event at CBD COP 10 (October 2010) Workshop in London (February 2011) Workshop in Brazil (March 2011) Final output expected early May
