The United Nations Development Program’s flagship index of wellbeing and social progress, the Human Development Index, no longer captures what humans need, and needs to be replaced by a Green Human Development Index. That’s what I’ll argue in this post.

First, some context for those who do not know the Human Development Index (HDI). The HDI is the main index of the annual Human Development Reports, which, since 1990, have been published by the United Nations Development Program (UNDP). The reports analyse how countries are doing in terms of the wellbeing of their citizens, rather than the size of the economy. In 1990, the Pakistani economist Mahbub ul Haq had the visionary idea that in order to dethrone GDP per capita and economic growth as the yardstick for governmental policies, an alternative index was needed. He asked Amartya Sen to help him construct such an index. The rest is history. The HDI became a powerful alternative to GDP per capita. It consists of three dimensions and several indicators. The first dimension is human life itself, for which the indicators are child mortality and life expectancy. The second dimension is knowledge, captured by school enrollment rates and adult literacy rates. And the last dimension is the standard of living, for which the logarithmic function of GDP per capita is used.

It is easy to criticize the HDI for not capturing all dimensions of wellbeing, or for other shortcomings. For whatever those academic arguments are worth, there is no denying at how successful the HDI has been at accomplishing its two primary purposes: to dethrone GDP per capita and economic growth as the sole yardsticks for societal progress, and to stimulate policy makers to put human beings central in their institutional design and policy making. And by that yardstick, the HDI has been a great success. Each year, the release of the Human Development Reports captures the attention of media and policy makers worldwide. Many politicians and governments care about their ranking in comparison with other countries. And, most importantly, the political power of the HDI provides an incentive for countries to try to invest more in education and health, combatting child mortality and increasing life expectancy.

Yet, it is now time to abandon the HDI. Paradoxically, this is not despite, but because of its political success. The reason is that we have entered the Anthropocene – the geological epoch in which the human species is changing ecosystems and the geology of the Earth. The most well-known of those changes that humans have caused is climate change. And since these ecosystems and planetary boundaries in turn affect human flourishing, they must be central in any analyses of that human flourishing. [click to continue…]
