Carbon dioxide (CO2) emissions are an input that contributes to climate change. That is why we often hear that the reduction of these emissions is urgent. One might ask when this gas found in nature became dangerous. How this is linked to climate change is another question. We invite you to read this note so that you are more clear on the subject.
What are CO2 emissions?
Let’s start by talking about carbon dioxide (CO2). It is a gas composed of oxygen and carbon. It is colorless or odorless. It is in the atmosphere as part of the carbon cycle. In other words, we are talking about the natural circulation of that element between the atmosphere, oceans, land, plants, and animals.
It is worth mentioning that CO2 emissions come from many natural sources. Until then, there is no problem. However, emissions linked to human activities are responsible for their harmful rise in the atmosphere. This process was caused by the industrial revolution.
Why are CO2 emissions dangerous?
As already seen, human activities are changing the world’s carbon cycle. In other words, they add more CO2 to the atmosphere and affect the ability of natural dissipators (such as forests) to remove it from the atmosphere. Likewise, it affects the capacity of soils to store carbon.
In that sense, these emissions are one of the main causes of climate change. This situation is exacerbated by the fact that CO2 stays in the atmosphere for a long time. CO2 is the greenhouse gas best known for being primarily responsible for preventing the escape of heat from the lower layers of the atmosphere.
In addition to this, the burning of fossil fuels is the main human activity that emits CO2. This includes coal, natural gas, and oil used to generate energy and facilitate transportation. In addition, some industrial processes and land use changes also emit CO2.
Actions from citizens
From home or work, we can contribute to the reduction of CO2 emissions. An average temperature of 18 to 23 degrees Celsius should be maintained. This will allow for energy savings. In addition, local and seasonal foods should be eaten. The refrigeration of products in cold rooms should be avoided.
We must also use the three principles of the circular economy: reduce, reuse, and recycle. With this, we can extend the life cycle of the products. In addition, it is useful to plant trees and take other initiatives.
CO2 Emissions Reduction Day is celebrated every January 28. It is also called the World Day of Action Against Climate Change. This day is designated by the UN to raise people’s awareness about this issue and the environmental effects it causes.
