The social origin of global warming

Next months, these posts deal with the challenges of Earthlings and also with the prospects of bringing humane cities closer. These posts represent the most important findings of my e-book Cities of the future. Always humane. Smart if helpful, updates and supplements included. The English version of this book can be downloaded for free here and the Dutch version here.

As the map below shows, poorer countries have already suffered more from global warming because they are located in the warmest parts of the world, like Africa, South Asia, and Central America. It also applies to the southern and poorest part of the US.

There is another reality to face. Not only the poorest countries will suffer most from climate change, they hardly can be blamed for it. A recent Oxfam report Extreme carbon inequality shows that the poorest half of the world population – around 3.5 billion people – is responsible for only 10% of total global emissions from individual consumption. About 50% of the emissions come from the richest 10% of people around the world. They have an average carbon footprint that is 11 times as high as that of the poorest half, and 60 times as high as that the poorest 10%. Even a 50% reduction in consumption by the top 10% and a doubling of consumption by the lower 50% would result in a worldwide decrease of consumption of about 15%[1]. Within all countries, the production of greenhouse gasses varies with income.

The graph shows that the concept of rich versus poor countries is partly misleading. A small part of the population of all countries has affluent and still-growing opportunity to consume and to contribute to the production of greenhouse gasses; the majority of the population stays far behind.

This national elites with its numerous connections with international business and politics have prevented adequate social and environmental policies for more than half a century, including the only measures that could have prevented global warming, namely the internalization of external costs[2] and in particular carbon tax[3]. The result: the economic prospects of the majority of the global population stay behind and moreover it will suffer most from global warming.
