Without combustion engines, better of course

FeaturedWithout combustion engines, better of course

When a single vehicle pollutes approximately one ton of CO2 each 5000 km, this optimistic mathematical equality —because there are vehicles that could surpass two tons or more in the same distance— permits to calculate other equalities thinking with applied interests toward contemporary societies. It has a reason: to understand that electric vehicles seem the unique available solution for one of the most important issues faced by the human specie.

The line of argumentation is related to multiplication and numerical data coming from publicly available resources. None should argue about the number of inhabitants living at some cities or how many vehicles are being used there each day. For instance, a little city with 100.000 people might have more or less 50.000 registered cars. If those registered cars travel 1 km at the same time, how much carbon dioxide and other pollutants pass to the public air?

That's easy, if 5000 km create a ton, we have 50.000 cars traveling 1 km, then 50.000 km are 10 CO2 tons. This number is already scary, but it's only the beginning.

The average distance in a usual car per year was estimated of about 15.000 to 20.000 km. Let's take here the maximum because it's for calculating the possible impact without making lucky assumptions. 20.000 km divided by days in a year are 54,7 km each individual day. For this reason, placing one kilometer in the first calculation was more than unreal.

50.000 registered cars multiplied for the average distance in kilometers per day is 2.375.000 kilometers. To get the conversion in tons, remind that 5000 kilometers is one ton. We have 475 CO2 tons each day, 173.375 tons per year.

Avoiding possible confusions, a new equality: 50.000 cars create 173.375 tons per year, assuming an average distance driven per year of 20.000 km and 200 gr/km.

It permits to jump to other cities with more combustion cars, like New York, with more than 10.000.000 vehicles. No worries? We humans, breathe air and expect an atmosphere being ready for protecting us.

Even in planetary terms, carbon dioxide is raising constantly and it has a mathematical explanation. Entire seas of subterranean oil are being transformed to massive amounts of carbon dioxide, and this unfortunate —curious word in context— behavior interacts with air composition increasing its toxicity. No rich people could forget that the air that they breathe is worse and that dirtiness affects quality of life, so the luxury is to understand what affects to everyone and take actions.

Climate adversities are eventually fatal and few individuals remain without associating climate change with related phenomenons.

New York, a great city and very populated. Ten million vehicles produce per year: 39.931.000 tons.

~80.000.000 in two years, ~120.000.000 in three and so on.

The number of world's registered vehicles was recently calculated in more than a billion. The calculation is always simple with this formula:

((Number of vehicles · Average distance in km per day) / Kilometers for a ton) · Days in a year

(( · 54,7) / 5000) · 364 = 3.993.100.000 carbon dioxide tons each year.

There's room for other equation in terms of generated revenue per carbon dioxide ton. At least today, but we choose to buy water gallons and make sport so that business is not working thanks to our demand.
