Title: Pilot Environmental Sustainability Index


1
Pilot Environmental Sustainability Index
  • Presentation to ISPS Interdisciplinary Faculty
    Discussion Seminar on the Environment
  • Dan Esty, Yale
  • Marc Levy, Columbia
  • May 5, 2000

2
The Environmental Sustainability Index is the
result of a partnership involving
  • Global Leaders for Tomorrow Environment Task
    Force, World Economic Forum (Kim Samuel-Johnson,
    Chair)
  • Yale Center for Environmental Law and Policy
    (YCELP), Yale University (Dan Esty)
  • Center for International Earth Science
    Information Network (CIESIN), Columbia University
    (Marc Levy)
  • The report can be obtained at these web sites

3
The Need for an Environmental Sustainability Index
  • Counterpart to Competitiveness ndex and other
    economic performance measures
  • Benchmark environmental performance
  • Better goals, programs, and policies
  • Clarify environment/economic tradeoffs

4
Pilot ESI Builds on Work of
  • OECD
  • UN Commission on Sustainable Development
  • Consultative Group on Sustainable Development
    Indicators
  • Numerous other local, national, and international
    efforts

5
Our Objectives
  • Create an index that
  • Provides comparability across a wide range of
    countries
  • Focuses on environmental aspects of
    sustainability
  • Expresses results as a single number per economy,
    but permits more sophisticated disaggregation and
    analysis
  • Builds on an analytic foundation
  • Serves as a working prototype meant to encourage
    debate, dialogue, learning

High numbers correspond to greater levels of
environmental sustainability

  • Land

Analytical Foundations
  • Social and Institutional Capacity
  • Science/Technical Capacity
  • Rigorous Policy Debate
  • Environmental Regulation and Management
  • Tracking Environmental Conditions
  • Eco-efficiency
  • Public Choice Failures
  • Global Stewardship
  • Contribution to International Cooperation
  • Impact on Global Commons
  • Human Vulnerability
  • Basic Sustenance
  • Public Health
  • Environmental Disasters

Empirical Inputs
  • For each factor, we identified 1-6 variables to
    serve as quantitative measures (65 total)
  • For this pilot, we weighted the factors equally
    in computing the Index

5 components
65 variables
21 factors

Putting the Index to Use Assessing
Environment/Economic Tradeoffs
As hypothesized by Michael Porter, there may be a
connection between good economic performance and
good environmental performance
Environmental sustainability does not appear to
impose a constraint on economic growth
14
Among Similar Economies the Importance of Choice
is Clear
How vigorously to pursue environmental
sustainability, and how vigorously to pursue
economic growth, appear to be two separate choices
15
Why does this matter? Four perspectives on the
relationship between economic performance and
environmental sustainability
Difficult tradeoffs policy dilemmas
Environmental Kuznets just be patient
Environment
Economics
Good things go together policy free lunch
Good indicators are vital
All combinations are possible importance of
responsible policy choices
16
Conclusions(Does the world really need another
environmental indicator?)
  • Measuring environmental sustainability is
    possible and useful
  • This is a surprising, and encouraging, result
  • Some aspects appear to be easier to quantify than
    others
  • Some surprises here (capacity v. stress)

17
Conclusions
  • A future ESI can improve on the Pilot
  • Investment in data creation
  • Most global environmental monitoring programs are
    based on 19th century models time to move
    forward
  • Pluralistic, distributed networks (no central
    bottlenecks)
  • Greater use of civil society
  • Remote sensing and other advanced technologies
  • More sophisticated methods to weight factors and
    test validity, understand underlying assumptions
    and values
  • Factor analysis, time series analysis, regression
    analysis
  • Interactive, open version
  • Permit users to change factors and variables,
    change weights, add new variables
  • Scalable version
  • Permit users to integrate global, national,
    regional and local indicators as appropriate to
    their needs

18
Project Status
  • Pilot
  • Pilot Index presented in Davos 1-31-00
  • Detailed peer-reviewed critiques prepared
    February-April, 2000
  • Presentations to various policy and academic fora
  • Detailed review within several organizations and
    governments
  • 2001 Index
  • Reviewing results of peer reviews and other
    commentary
  • Planning refinements in methods, improvements in
    data, expansion of country coverage.
  • Considering devoting special effort to a
    particular sector (e.g. water)
  • To be released January 2001

19
Payoff
  • Strengthen quality of scholarly debates and
    research programs
  • Enhance assessment of national environmental
    performance greater accountability
  • Improve formulation of policy targets and
    priorities (identifying critical weaknesses)
