On 22 March 2024, the German Federal Council gave its approval for the authorisation of climate-friendly pure diesel fuels. The beacon of hope of this new era is HVO100, short for Hydrotreated Vegetable Oil. This fuel, which is produced from the conversion of vegetable oils or recyclable waste materials, is to be available at German filling stations from 13 April 2024.
The sight of huge, powerful lorries on Europe's motorways could soon become a reality. The European Parliament recently passed a measure that could make it possible to allow so-called "mega trucks" on the roads of EU countries. But what does this mean for the climate? Can these giants really reduce emissions from freight transport?
Electromobility currently seems to be the industry's irrefutable future. But while companies like Volkswagen are forging ahead, other groups such as BMW, Skoda, General Motors and above all Mercedes are changing their strategy. Instead of focussing exclusively on electric drives, they are once again focusing more on customer requirements and are even planning to develop the diesel further.
In January 2021, Airbus will put its first zero-emission hydrogen fuel cell into operation. This is an important step towards the development of a hydrogen-powered aircraft. By opening a development centre for hydrogen technologies in Lower Saxony, Airbus is strengthening its presence in Germany and underlining its ambitions in the field of climate-neutral aviation.
The Mayor of London, Sadiq Khan, has announced a pilot project to install air filters in 200 of the city's most polluted schools. At first glance, this sounds like a commendable initiative. But why did it have to come this far?
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?
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.
On 11 January 2024, the District Administrative Court in Krakow, Poland, stopped the city's planned low emission zone for the time being. The project, known as the Clean Transport Zone (SCT), was intended to designate a part of the city where only cars with certain Euro standards would be allowed to enter. However, despite the good intentions of the city council, the court declared the project invalid.
The discussion about sustainable mobility has recently focussed increasingly on e-fuels. E-fuels, synthetic fuels obtained by reversing the combustion process, have the potential to offer a climate-friendly alternative to electric drives. However, their environmental compatibility and energy balance still need to be investigated further.
Austrian Post has announced that it will switch its entire lorry fleet to HVO (hydrogenated vegetable oil) by mid-2024. A bold step that makes the company a pioneer in the industry. The progress is undoubtedly impressive, but also raises some questions.
