Warning on affluence

We already know the answer: we¡¯re living in too much style. The problem is that our living standards are destroying our basis of life. From an ecological perspective, we can¡¯t afford to be rich. That is the key outcome of our perspective recently published in the journal Nature Communications entitled ¡°external page Scientists¡¯ warning on affluence¡±.¹

Consumption leads to ecological crises

We analysed the scientific discussion on the relationship between wealth, economy and environment, and came to the following conclusion: the economic growth imperative and the associated overconsumption are the main drivers of today¡¯s environmental crises. All the small and large products increasingly consumed by growing numbers of people carry weight: they consume land, water and raw materials, destroy habitats and warm the planet.

In fact, the world's wealthiest 10 percent (which includes those with an annual per capita income of CHF 13,000 or above) cause between 25 percent and 43 percent of ecological damage, while the poorer half of the world is only responsible for 12 percent to 27 percent.² The gap is particularly big when it comes to climate: the richest 0.54 percent (about 40 million people) cause almost 14 percent of all consumption-based CO₂ emissions.³

Green growth is a myth

Many countries see a solution through clean technologies. Switzerland too is promoting ¡°green growth¡±, which aims to protect the climate and natural resources by ¡°decoupling¡± the economy from harmful effects.⁴ In our article, however, we show that there is no empirical basis for the belief that this required ¡°decoupling¡± is actually taking place. From a global perspective, all technological advances so far have been offset, primarily by growing economies and less so by population growth⁵. The affluence of the world has grown, and with it, environmental damage continues to increase. We believe that the idea that this will change as fundamentally as required in future is highly unlikely.⁶

Conversely, this means that if we want to solve existential problems such as climate change and species extinction, we cannot rely on technology alone. In addition to technological developments, it is essential to decrease the consumption levels of richer societies and develop a simpler, more frugal lifestyle.^{6, 7}

This is easier said than done. In our article, we show that the biggest obstacle to change is the systemic pressure toward growth⁸: our national economies are geared towards rising returns. Markets and companies promote overconsumption. Status goods shape social norms. The affluent classes support this system by shaping politics in their favour. This drives a constant growth spiral⁹ that prevents the necessary change.

What is really important to us

But how can we reduce the overwhelming power of consumption? We can certainly try to change our lifestyles. However, I believe this is not just the duty of individuals ¨C structural (and cultural) change is also required: we must find sustainable economic paradigms.

The approaches described in the article put the well-being of people and ecosystems above profit and material affluence. The research field of the post-growth economy investigates how a world would function without growth (see also this blog post). Characteristics of such a world may include more local production, cooperative forms of business, a greater people¡¯s voice, guaranteed income, reduced working hours, ecological taxes, sufficiency and closed material cycles.¹⁰ On these issues, I believe that still too little research is being carried out, both elsewhere and at ETH.

We must hold an in-depth discussion on what is right for us as a society and the standards on which we want to base our economy and way of life. A starting point could be the realisation that the material affluence we have been striving for may not be quite so desirable.
