"Researchers at the University of California, Berkeley, who operate a network
with dozens of sophisticated sensors in the San Francisco Bay Area, have found
that between 2018 and 2023, pollution decreased annually by an average of 1.8%,
and that this decrease is almost exclusively due to the increase in the use of
EVs.
It's not a huge number, certainly not when compared to the total emissions of
such a huge area, although it is estimated that to meet California's ambitious
goals, a 40% reduction over 1990 levels by 2030, would require a fall of 3.7%
per year, a little more than double, that many predict will not be attainable.
However, if the reduction obtained is almost entirely due to the use of EVs,
there is room for hope: despite the fact that California in general and the San
Francisco Bay Area in particular constitute, within the United States, the
place with the highest adoption of EVs (in a country shamefully addicted to gas
guzzlers) and with a high percentage of energy obtained from renewables, we are
talking about a total of 1.1 million electric vehicles out of a total of more
than twenty-eight million, less than 4% (and that, including plug-in hybrids,
which serve no purpose in terms of emissions' reduction). If, as is the case in
Norway, more than 90% of new vehicles purchased were to be electric and the
percentage of energy coming from renewables were more than 99%, the potential
for improvement would be extremely high.
What would the mass use of EVs in cities mean? Although they only cover 3% of
the planet's surface, they produce around 70% of emissions, which gives an idea
of the potential. What's more, those of us who live or work in a city know: you
only have to look at the collar or the cuffs of a white shirt to know that if
the equivalent of that accumulates in our lungs every day, that cannot be a
good thing."
