The Union Environment Ministry has said the 2022 Environment Performance Index (EPI) is unscientific and biased in its methodology.

 

What did the report say?

  • Ranking 180 countries on the basis of their green performance on those indicators, EPI 2022 put India at 180th position.
  • On the other hand, the largest historical polluter, the US, has been ranked at 43rd and the biggest current emitter China has been ranked at 160th position.
    • Denmark, UK, Finland, Malta and Sweden have been ranked at the top five positions due to their better performance.
  • The report claimed that India prioritised economic growth over environment.
    • The lowest scores overall go to
      • countries that are struggling with civil unrest or other crises, including Myanmar and Haiti, or
      • Nations that have prioritised economic growth over environmental sustainability, such as India, Vietnam, Bangladesh, and Pakistan.
  • With markedly poor air quality and quickly rising greenhouse gas emissions, India, for the first time, comes in at the very bottom of country rankings.

 

Why India rejected the report?

  • Report based on unfounded assumptions —
      • As per India, the report used many indicators based on unfounded assumption.
      • Some of these indicators used for assessing performance are extrapolated and based on surmises and unscientific methods.
      • Environmental and climate experts also said the methodology does not consider per capita emissions and different socio-economic conditions across countries.
  • Reasons for change in assignment of weights has not been explained —
      • As per India, the weight of indicators in which the country was performing well has been reduced.
      • And reasons for change in assignment of weights has not been explained in the report.
  • The principle of equity is given very low weightage —
      • The principle of equity is given very low weightage in the form of the indicators like GHG emission per capita and GHG emission intensity trend.
      • The common but differentiated responsibilities and respective capabilities (CBDR-RC) principle is also barely reflected in the composition of the index.
      • India is party to the Paris Agreement and has given a goal of net zero by 2070.
      • Hence, comparing it to countries with projected 2050 emissions level in 2050 equal to or below zero receiving the maximum score is against the principle of equity as enshrined in CBDR-RC.
  • Flawed methodology —
      • To buttress its case, the Environment Ministry pointed to a new indicator in the Climate Policy objective of EPI, Projected GHG Emissions levels in 2050.
      • This is computed based on average rate of change in emissions of the previous 10 years instead of modelling that takes into account –
            • a longer time period,
            • the extent of renewable energy capacity and use,
            • additional carbon sinks, and
            • the energy efficiency of respective countries.
  • Both forests and wetlands of the country are crucial carbon sinks. These have not been factored in while computing the projected GHG emissions trajectory up to 2050 by EPI 2022.
  • Uncertainty in Copernicus air pollutant concentration —
      • India said that the Copernicus air pollutant concentration data have higher uncertainty in regions with less extensive monitoring networks and emissions inventories.
      • This limitation reduces the chance of accurate assessment of air quality in India.
      • Also, the indicators on water quality, water use efficiency, waste generation per capita which are closely linked to sustainable consumption and production are not included in the Index.
  • India’s record is impeccable —
      • India has already achieved the target of 40% of installed electricity capacity from non- fossil fuel-based sources, 9 years in advance of its commitments.
      • In 2015, as part of its nationally determined contributions under the Paris Agreement, India had committed to achieving 40% of its installed electricity capacity from non-fossil energy sources by 2030.
  • Enough room for improvement in the Index —
      • The index computes the extent of ecosystems but not their condition or productivity.
      • Efforts must be made to include metrics that truly capture ecosystem productivity such that:
      • Regulatory, provisioning as well as cultural services provided by various ecosystems like forests, wetlands, croplands are assessed and reflected in performance.
      • Indicators like Agro biodiversity, soil health, food loss and waste are not included.
      • Although they are important for developing countries with large agrarian populations.

 

About the ‘Environment Performance Index’

  • EPI which ranks 180 countries on 40 performance indicators including climate change, environmental public health, biodiversity etc.
  • The report is prepared by the researchers of –
    • Yale Centre for Environmental Law &Policy and
    • Centre for International Earth Science Information Network Earth Institute, Columbia University.
  • The EPI offers a scorecard that highlights leaders and laggards in environmental performance.
  • It also provides practical guidance for countries that aspire to move toward a sustainable future.
  • Framework —
      • The 2022 EPI uses 40 performance indicators grouped into 11 issue categories further grouped in three categories
            • Environmental Health
            • Ecosystem Vitality
            • Climate Change
      • Based on their performance, it ranks countries on a scale of 0-100 from worst to best performer.
