The State of Green Transition Index: Comparing Countries and Cities

While the urgent need to address climate change is becoming increasingly mainstream, a greater understanding of the underlying changes to societies that will be required to address this challenge must be facilitated. Green economy and green growth – powerful labels to reorient global growth on more sustainable pathways – must be emphasised in the international discourse on climate change.

In this context we have released the State of Green Transition Index, a visual communication tool to empower commercial and political decision makers, as well as international media, with a reference point for both national performance in the green economy and how experts rank it. Consider it a source of knowledge and inspiration, meant to spur conversation around green growth by conveying contexts that we all are familiar with; the countries and cities that we live in.

- Enter the State of Green Transition Index

What can you compare?
The Transition Index enables you to compare the green growth performance of 59 countries and 69 cities to Denmark and Copenhagen.

Based on your choice of green performance categories (18 indicators underlying 4 dimensions) you can compare the ‘technical performance’ and ‘perception’ of your country - or the ‘perception’ of your city - and see an aggregated ranking based on your choices.

For instance, see how your country’s technical performance compares to Denmark in areas such as Clean Air, Buildings and Transport. Or learn how your city compares to Copenhagen in terms of Leadership & Climate Change.

Dimensions (+ indicators)

  • Leadership & Climate Change (Head of State, Media Coverage, International Forums, Climate Change Performance)
  • Efficiency Sectors (Buildings, Transport, Energy, Tourism)
  • Markets & Investment (Renewable Energy Investment, Cleantech Innovation, Cleantech Commercialisation, Green Investment Facilitation)
  • Environment & Natural Capital (Agriculture, Air Quality, Water, Biodiversity & Habitat, Fisheries, Forests)

Data source
The State of Green Transition Index is based on data from the 4th edition of the Global Green Economy Index (GGEI). The GGEI is produced by Dual Citizen LLC and measures the performance of 60 countries and 70 cities in the green economy and how experts asses that performance.

Like many indices, the GGEI is a communications tool, signaling to policy makers, international organizations, the private sector and citizens which countries are successfully orienting their economies toward greener growth pathways and which ones are not. Importantly, the GGEI also generates perception values, offering unique insights into how communications and information exchange can be leveraged to further advance green economic growth. Both components of the GGEI are critical to better understanding how countries can leverage data analytics and strategic communications to advance their standing in the global green economy.

First published in 2010, this new edition of the GGEI presents a revised methodology resulting from a strategic review that revealed opportunities for broader sector coverage, more focus on environmental performance and enhanced data collection and processing methods.
