pollution control

Today air pollution has become one of the main environmental issues we are facing as a species. Coal-burning and industrialization have led us to all of the technological advancement as well as hurt our planet’s ecosystem. The constant emission of carbon has played a huge part in the depletion of the ozone layer. Although the number source of air pollution is coal-burning plants creating electricity, the transportation sector isn’t far behind. Countries all around the world are trying to solve this issue via different methods. However, before looking at the solution, let’s understand the problem first.

 

How transportation sector is contributing to air pollution

  • The first significant source of sooty smog was from the coal combination. However, the issue was solved in major European and North American cities as soon as it was on the verge of becoming dangerous.
  • However, once that was solved, emission from the road, water transport, aircraft, and rail transports became one of the major sources for stratospheric ozone depletion, climate change, and acid deposition.
  • According to the most recent research, road traffic emissions have been the main cause of the effects of urban air quality on human health.

 

What transportation sector is doing to solve this

Now we have seen how the transportation sector has affected air pollution. Let’s take a look at what is currently going on based on the recent data.

  • Between the years 1990 and 2017, the emission of air pollutants: carbon monoxide and non-methane volatile compounds, sulfur oxide, and nitrogen oxides have been significantly reduced by 87%, 66%, and 40% respectively.
  • Since the year 2000, the reduction in emissions as 44% for PM 2.5 as well as 35% for PM 10 has happened.
  • Two decades ago, there was an estimation on the deduction of emission. Although, the results were not up to the estimations and continue to decrease. However, the emission of sulfur oxides has not been deducted.
  • In the year 2017, the emissions were way lower than the last year before it. The emission of nitrogen oxides and carbon mono oxides was decreased by 3% as well as 3.2% respectively.
  • In the year 2017, the emission of sulfur oxides increased by 2.7% compared to 2016. However, it was still 1%lesser than the emission levels in the year 1990.
  • The emission from most of the transportation sector has declined, however, the emission of nitrogen oxide emission has increased in recent years. Even the emission level from air-transportation for all pollutants was increased.

 

How the emission can bring down to zero

As long as transportation is burning diesel and petrol for fuel energy, no matter how advanced and efficient our engines become the emission will never come down to zero.

Electric vehicles are one of the only hopes we have against emission and air pollution. However, electric vehicles alone cannot do much and we are going to need reusable electricity resources like Solar and Wind energy as well.
