Glad this issue is getting some attention, but the numbers in this study are a massive underestimate. They arrive at annual deaths of 274k-493k from transport emissions, but I think the reality is likely to be over 1 million.
In the US one of the best studies I have read puts auto related emissions deaths at 58k annually (28% of US air pollution deaths).
https://www.sciencedirect.com/science/article/pii/S1352231013004548. This maps closer to 1 million worldwide.
Many things this latest study misses:
- For some inexplicable reason they assume death rates flatten out at higher pollution concentrations while all latest evidence suggest they continue linearly. They admit adjusting for this would double the deaths in their study.
- They do not appear to adequately adjust for the increased proximity of tailpipe emissions to human populations relative to industrial emissions. Adjusting for this should significantly increase the weighting of transport pollution in overall pollution deaths.
- They ignore Nitrogen dioxide which has been linked to deaths from diseases such as asthma.
- They only consider deaths from 6 diseases (stroke, ischemic heart disease, chronic obstructive pulmonary disease, lung cancer, lower respiratory infections and diabetes) and ignore asthma, chronic kidney disease, preterm birth and cognitive decline which are all already known to be impacted by pollution.
- It takes a long time to prove which diseases are impacted or caused by pollution but I expect many more diseases including many cancers are likely to be connected to pollution in the coming years.
Any thoughts on this
@Fact Checking?
I have no idea why this study would try to lowball its estimates, but in any case, even 274k-493k annual deaths (lets call it 500,000) is a global crisis and it is criminal that the media and politicians are doing so little to raise awareness or so little to prevent it when we already have superior and affordable solutions.
