Electric cars and particulate matter: how do they go together?

Air pollution has been with us since the beginning of industrialisation. It is omnipresent, especially in cities. However, with technological progress and the relocation of factories away from city centres, air quality has improved in most wealthy countries. A major source of air pollution, the internal combustion engine, seems to be slowly being replaced by electric cars. But are electric cars really the environmentally friendly alternative they appear to be?

Water shortages and the emergence of new environmental zones - climate change and its impact on soil moisture

The climate crisis, one of the greatest challenges of our time, is becoming ever more tangible and its effects ever more evident. Paradoxically, one of the main causes of the alarming rise in CO2 emissions is the lack of water. This leads to dry soil, which in turn produces more particulate matter and favours the creation of new environmental zones.

Emissions from the construction industry: first steps towards the zero emissions target

Construction sites and the construction industry itself are major emitters of CO2, particulate matter and other substances that contribute to air pollution in environmental zones and urban centres in general. However, the industry has already taken important steps towards zero emissions and climate neutrality: construction vehicles are becoming increasingly electric!

Electric flop: buses in Oslo break down in the cold

100 million euros in the sand - or snow. That is the sad result of the first onset of winter in Oslo. After the city invested this enormous sum in new electric buses in the spring, they have now simply broken down in the cold. Instead of emission-free local transport, the city has thrown a lot of money down the drain. It remains to be seen what the manufacturer Solaris will now do to avert the debacle.

Dystopia of the trackless tram: fine dust pollution in the guise of revolutionary local transport

It sounds like the forward-looking answer to urban transport problems: The first trackless tram in Australia. However, if you take a closer look at the facts, it quickly becomes clear that this is not the hoped-for revolution in local transport, but rather harbours a potential environmental problem.
