They assume that the world must reach net zero emissions by 2050, and so the appropriate benchmark is whether all countries are reducing emissions and reaching zero by 2050. For climate change, 53 per cent of the weight is allocated to these trends, and another 36 per cent to whether the continuation of these trends brings a country close to zero emissions in 2050. Specifically, they rely heavily on the trend of greenhouse gas emissions by a country in the past decade as an indicator of progress. The Yale-Columbia researchers thus set themselves a near-impossible methodological problem to solve, and then proceed to make things worse with a really poor-even biased- choice of benchmarks. Unfortunately, the EPI 2022 produced by Yale and Columbia Universities is far from making even this modest contribution: The index is severely compromised by how it incorporates action on climate change mitigation.

At best, aggregate indices give a coarse picture: Top 20, middle of pack, or bottom 20, nothing more. We would argue that ranking countries is best done on some specific indicators such as urban air quality or domestic water pollution, for which metrics are relatively well-accepted and universal, and so comparisons are defensible. Arsenic is not counted by the EPI because it is not as widely prevalent as lead, which is included. For example, the EPI leaves out arsenic in water, which is a major threat in Bangladesh. Moreover, when ranking countries, one is essentially applying the same standard across vastly different socio-ecological contexts – this involves difficult choices. For example, indicators may focus on current rates of increase or decrease in environmental pressures (flows) - as the EPI does for carbon dioxide emissions and tree cover gains - but under-state the accumulated effect (stocks) that relates to actual harm, thereby ignoring past effects. In trying to quantify, aggregate and rank, index makers have to make judgements about what issues count, how they are best measured individually, and how much importance to give to each issue and indicator in aggregating.
