What are the Other Ways to Remove CO2 From the Atmosphere Than Reforestation?

Global warming is a concerning issue that poses a serious threat to the whole world. So, if we want to save Earth from warming, then the fuel-burning should stop, i.e., coal, oil, and gas must remain in the ground because when they are burnt, they produce CO2. It is known as greenhouse gas, which causes the atmosphere to trap heat radiating from the Earth into space.

Sadly, this is directly related to coal, oil, and gas burning found in the forests, plankton, and plants over millions of years. Earlier, they stored CO2 from the atmosphere and maintained the balance of gases in the atmosphere. But as fossil fuels are burned, CO2 is released. Industrialized agriculture, slash-and-burn land clearing techniques are other contributing factors that makes it even worse.

While Reforestation could be a great option to retain back the balance, do we have other options?

Tip: If you wish to make Earth a safe place, buy biochar carbon certificates so that the seller can sell biochar at a lower price so that it is available to everyone.

Let’s have a look at what these options are!

Biochar As a Promising Option

Today, some scientists are looking at biochar as a promising technology capable of keeping CO2 out of the atmosphere. Biochar is formed when organic material is heated and pressurized in an environment where oxygen is as low as zero. This biochar formula is spread on arable land in a powdered form, where it acts as a fertilizer to increase the amount of carbon content in the soil. Hence, biochar for carbon removal is a great way to reduce carbon from the atmosphere.

 Storing CO2 in the Ground

When looking at other methods that can keep CO2 away from the atmosphere, storing CO2 deep in the Earth is a great way. This is one practice that is practiced in Norway’s oil fields. However, it can be a little controversial as storing CO2 underground can lead to earthquakes and leakage in the long-term.

Therefore, a different method is being practiced in Iceland, wherein CO2 is sequestered into porous basalt rock to be mineralized into stone. But, both methods still require more research. Capturing and storing CO2 underground is achieved using chemical processes that extract the gas from the ambient air. This method is called direct air capture (DAC) and is practiced in many parts of Europe.
