Sustainable Green Transition

Roger B

An interesting piece in the Engineer:

The Engineer - Green transition mineral demands under scrutiny

I wonder if some real numbers will come out of this? 

'According to the WRF and Empa, the extraction and processing of material resources is responsible for 90 per cent of biodiversity loss, 50 per cent of global greenhouse gas emissions and 30 per cent of air pollution impacts. The energy transition and growth in the infrastructure stock globally risk making environmental challenges even more acute.'

Renewable energy sources require a lot of resources.

  • Be a little careful, that quote is not saying that "extraction and processing of material resources for renewable technologies" is responsible for those losses (i.e. if we cancel renewable plans those losses will stop), these losses appear to be from all extraction activities. The source of this quote here https://www.empa.ch/web/s604/world-resources-forum-2023 is slightly but not much clearer.

    But yes, carbon emission reduction is bloomin' complicated. The trick is proper emission lifecycle analysis, fortunately there are now lots of people who are very good at this, next step is to get them listened to!

    Hi Mr. Andy,


    The world is moving to electric vehicles at a fast pace, but even the garages that install them do not have enough in-depth knowledge on the matter.
