Room wanted, for a while

I wish our apartment had a spare room. Just one. Now that the children are a bit older, it would be nice for them to have a space of their own. We would only need it for a few years, just until they leave home. After that, I would happily hand it back – my wife and I wouldn’t use it.

That’s not how it works, I hear you say. But…

Better stay on the ground?

Linking people, but sustainably

For now, the times in which the aviation industry experienced nothing but growth are over. As a result of the Covid-19 pandemic, countless planes remain grounded. Moreover, many people are asking whether they really need to fly. It has quickly become apparent that many business trips are unnecessary. Video conferencing works. And…

Power-to-X

Not a universal solution

Remember Desertec? At the start of the new millennium, someone in Germany came up with the bright idea of harnessing the abundant sunshine in North Africa to generate electricity in vast solar energy systems and transferring it to Europe via long-distance power lines. The idea met with an enthusiastic response. There was one problem,…

Living without plastics – but how?

For a new culture of sorting

I pulled almost 30,000 tetrapacks out of the stream of waste – in a single shift. That was in the mid-1990s, when I spent a couple of days in a sorting plant where I sorted waste by hand. They were probably some of the most instructive days I have ever spent at work, providing insights into our throwaway culture, our sorting habits…

Our food – a risk?

Giving up is not hard to do

No meat? On a trek in 1996 in the company of vegans and vegetarians I noticed: it’s actually OK. And I didn’t even find it particularly difficult. Perhaps because pasta, pancakes and a pizza from the camping stove were particularly delicious. But perhaps also because I didn’t immediately become a strict vegetarian but have continued…

The 2020 emissions gap

Leading the way on climate action

Climate change is a headline topic at last – in the media, in politics, in public debate. More and more people are aware that now is the time for bold and urgent action. This awareness is partly the result of the tireless protests by the Fridays for Future movement, but the impacts of global warming, including here in Germany, are…

Digitalisation

Data: a precious resource

Some say it’s the new oil; for others, it’s the new water. Others describe it as quite simply the most important resource for the 21st century. In our digitalised society, data has immense value. The European Commission estimated the value of the data economy for the EU alone at €272 billion in 2015. But to a very large extent, data… more

Less emissions, more quality of life

Pathways out of transport breakdown

Every day, anyone who lives in a city or conurbation can see that in many places our transport system is on the brink of collapse. That is the case in my home city, Berlin. Every morning I cycle past kilometre-long lines of vehicles crawling bumper to bumper through the city. The number of hours that many people in Munich, Berlin or… more
