Over the last few years, our awareness of the impact of carbon emissions has risen sharply. In response, many cities are trying to reduce the use of cars (especially ICE) in inner city areas in favor of pedestrians, cyclists and public transport.

But does such an approach actually have a real difference in air pollution levels? Let’s look at:

What is the problem with cars?

You probably know the statistics, but let’s just do a quick refresh.

According to joint research from Harvard University and various universities in the UK, more than 8 million people died in 2018 from fossil fuel pollution.

In fact, researchers estimate that exposure to particulate matter emissions from fossil fuels accounts for 18% of total global deaths in 2018 – just under one in five.

However, not all emissions are from cars. Industrial production, oil refineries, natural phenomena such as weather, dust storms, fires and agricultural activities contribute to pollution levels.

But 2020 research has revealed this 41% of global transport emissions are from ICE (gas) cars. The older the car, the worse the pollution.

But things are not so simple.

EVs are not perfect

It’s not just ICE’s exhaust fumes that are to blame. In fact, 55% of road traffic pollution comes from particles that are not used by both types of cars. From this, About 20% comes from brake dust that can cause inhalation significant respiratory problems.

Not surprisingly, there is a big push to get cars (and trucks, as far as practical) out of big urban areas with high traffic.

What are some initiatives?
