The World Medical Association (WMA) launched in Oct. 2014 a call for all governments to reduce soot from lorries, cars, planes etc. for sake of health and climate.
I brought in the idea and discussed a lot worldwide. I attend congresses only if virtual or if they are within reach by (night) trains.
My work is to influence people and institutions, especially companies, to work with health and climate and not against. Co-benefits are the core, meat and muscle powered mobility but also stress through multi-options (fear of missing out).
I could reduce the emissions of my house (12 flats) nearly to zero, and use bicycle, train or hybrid for my frequent traveling.
