You will probably be saturated with hearing about climate change, global warming, the growing greenhouse effect, the dire consequences that all of them have on our planet and the urgent need to take action on them. But do you know exactly how to do it? Do you know what solutions could be taken? Surely you have an idea, but if not, don't worry. Since there are many measures to take depending on the problem we are dealing with, at Ecologista Verde we are going to delve into the dreaded greenhouse gases in particular. Next, we tell you how to reduce greenhouse gases.
What are greenhouse gases or GHG
The greenhouse gases (GHG) They are gases found in our atmosphere and whose function is to absorb and emit radiation from sunlight within the infrared range. These gases are fundamentally responsible for the so-called "greenhouse effect"; which, despite its negative current connotation, is a natural phenomenon without which the temperature of the earth's surface would be around -18ºC on average, that is, they are necessary for life to develop on our planet. However, today the concentration of these GHGs is becoming too high, which is causing the environmental havoc that we know today.
Some of these gases are water vapor, the famous carbon dioxide (CO2), methane (CH4), nitrogen oxide (NOx) and ozone (O3). Find out more in this other Green Ecologist article on How long greenhouse gases remain in the atmosphere.
What are the sources of greenhouse gases
As we mentioned earlier, greenhouse gases are found naturally in the atmosphere in small amounts, such as water vapor, carbon dioxide or methane. However, since the Industrial Revolution, due to use of machinery and the increase of factories, many other greenhouse gases are produced exclusively from anthropogenic actions, that is, human actions, as is the case of Aerosols.
Although it is true that, if the amount of greenhouse gases begins to be high, there are natural processes that absorb a part of them to rebalance the atmosphere, but with the emissions produced by man the natural mechanisms of "restoration of the atmosphere "have been saturated.

How to reduce greenhouse gas emissions
The most immediate measure, and one that you probably already had in mind, to reduce these GHGs is to reduce as much as possible the emissions of this type of gases, such as carbon dioxide, which is generated from the burning of fossil fuels. Here we explain how to reduce my carbon footprint, that is, the amount of carbon dioxide and other greenhouse gases that we generate in a particular way.
From this previous point we deduce, therefore, another measure that can be taken to reduce these emissions, and that is the use of renewable energy, such as solar or wind energy.
From the United Nations (UN) they suggest other actions that we can take ourselves to contribute to the reduction of greenhouse gas emissions, which are:
- Encourage the use of public transport or other sustainable means of transport such as bicycles or simply travel on foot to places close to which we often go by car or other means that produce gas emissions. In addition, traveling by bicycle or on foot helps to keep you in good shape, and your health will pay off.
- If you use the car unavoidably, regularly check the pressure of your tires, because if you keep them at an adequate pressure you will optimize the fuel efficiency.
- Recycle the waste you generate and reuse containers or other products before throwing them away.
- Contribute to reforestation work. Calculations ensure that a tree absorbs between 350 and 3,500 kilos of atmospheric carbon throughout its life.
- Insulate your home, as this way the cold or heat will be better conserved inside and we will contribute to improving energy efficiency. In addition, you will reduce the costs that occur with air conditioning and heating devices.
If GHGs are not reduced with actions like these, the consequences of what they already produce can get much worse, as we explain below.
Consequences of the excessive emission of greenhouse gases
The most immediate consequence of these GHGs is the increased greenhouse effect, by which the average surface temperature of the earth's surface is increased. This warming of the climate with its corresponding increase in temperatures is responsible for some consequences such as:
- The melting of the poles, which raises the sea level and increases the risk of floods, with all that these have associated with it.
- Increase in droughtsTherefore, air and water pollution will occur due to the absence of rains that "clean" the atmosphere.
This increase in the greenhouse effect seems to have been accelerated due to the rapid rise in the amounts of CO2 in the atmosphere. The reason for this seems to lie in the fact that the amount of carbon dioxide absorbed by the terrestrial biosphere (plants, oceans …) has probably been reduced.
Other serious consequences derived from the increase in the greenhouse effect are:
- Health problems such as skin cancer due to increased solar radiation.
- High intensity atmospheric phenomena, such as storms, hurricanes, tidal waves …
- Problems in biodiversity, because species of flora and fauna will be affected in their different ecosystems.
- Acidification of the oceans. The oceans absorb a large amount of atmospheric CO2 to buffer its high atmospheric concentration, however, when the ocean becomes saturated, the acidification process begins, which will affect marine species causing diseases, deaths and, in extreme cases, extinctions.
