Many more public transport needed to achieve greenhouse gas cuts by 2050If the world seriously objectives greenhouse gases gas emission and climate for the year 2050, technologies such as plug-in cars and alternative fuels is probably not enough. Instead, less light vehicle travel is essential to meet these objectives according to a new study by the University of California, Berkeley.
The personal mobility revolution is on.
In developed countries, where the emissions are now higher, for example, the study finds that a universal fleet of electric cars powered by carbon-free electricity, or 300 mpg cellulosic ethanol powered cars, or 1000 mpg ICE vehicles would be needed. Unfortunately, none of these possibilities, or a combination thereof, provide a "realistic, affordable or resilient pathway" forward.
So, while the light transportation needs to significantly more fuel efficient, better public transport and plans to reduce the average miles traveled must be part of the formula.
Ultimately, it seems clear that the future of personal transport will have to think far beyond the current box on wheels.
