Over the 20th century technology has pushed forward in many fields. As there were huge investments needed the public campaigns to support new technology without much further reflection of potential consequences have pulled many western societies into risky technologies. Except the Club of Rome there were very few to question the naïve beliefs that technological change will make societies rich and potentially even more equal. The recent report “Climate Inequality Report 2023: Unequal Contributions to Climate Change” has debunked both of these claims. More flying across the planet, particularly short city hopping, has allowed few persons to reap the benefits of the jet-set world, but contributed to climate change in excessive quantities. This is a fact when we compare major world regions among each other as well as within each country. It has to be the wealthy countries that have to shoulder the biggest share of the costs. It has to be the wealthy that pay higher contributions for their pollution. Society has to reign in technology more than ever before. Moreover, we still have to get the income and pollution distribution organised in a better way. It is not only an implementation challenge, but the major question of the 21st century to repair the damage largely caused throughout the 20th century.
