The transport They are essential for all societies due to the need to move from one place to another either short or long distances to carry out different activities.
But transportation is one of the main sources of global pollution most important due to the CO2 emissions and other harmful gases they generate.
To get an idea of the volumes of CO2 that each mode of transport produces, estimates have been established for each type of transport.
- A 1 km in a conventional fossil fuel car emits 150 grams of CO2.
- A 1Km by plane produces 180 grams of CO2
- A 1 km by bus emits 30 grams of CO2
- A 1km by rail 35 grams of CO2
If we add the people who travel around the world and multiply it by the number of kilometers they travel, it will give us the results million tons of CO2 and other polluting substances emitted into the atmosphere by means of transport.
How is it possible to realize the railway and buses They are the most efficient since they have the capacity to transport more people with the lowest level of emissions.
Emission levels are much lower in the hybrid or electric cars than conventional ones, but there are still few that circulate on the planet to reduce pollution levels enough.
Airplanes produce a significant carbon footprint because they consume a lot of fuel, but in recent years companies in this sector are designing and evaluating management improvements to reduce the contamination.
The use of biofuels It is one of the options that they are analyzing the most to use to reduce emissions.
Technology has advanced so much and continues to do so so that transport can be more sustainable but citizens must also collaborate by choosing to use the least polluting means of transport.
If it is achieved that most of the world's means of transport are sustainable due to low emissions, it will be possible to significantly reduce the levels of global pollution.
