Technologies like DAC are Gamechanger in Climate Change Reversal

climate change

Climate change and global warming are two global problems that have become a matter of concern for all human beings all over the world. We human beings burn fossil fuels just for the sake of our human civilization.

 

Fossil fuels emit a lot of greenhouse gases that result in irreparable damage to the atmosphere of our planet. Industrialization, urbanization, deforestation, and many other insensitive human activities are increasing carbon dioxide, methane, nitrous oxide, water vapour, and other greenhouse gases in the atmosphere. At this perilous time, it is necessary to take extra care of our planet. We should take extraordinary measures such as pulling CO2 out of the air of our planet.

To deal with the climate crisis, huge investment is necessary for DAC (Direct Air Capture) technology that can remove CO2 from the air and safely sequester CO2 underground. Thus, it helps in mitigating the worst impacts of climate change. For having net-zero emissions within this century, a huge amount of CO2 should be removed from the atmosphere.

Though DAC or direct air capture technology has often been considered expensive and not practical, researchers have found that it has multiple benefits such as DAC has no biophysical limit unlike other conventional carbon-removal methods like bioenergy or tree plantation. The technique needs no changes in the use of large-scale lands; it requires no arable land, which reduces the impacts on food production. One research scientist at a public university in San Diego, California claimed that the methods of DAC (direct air capture) are considerably more extortionate than many traditional mitigation methods, but costs would fall if firms get benefits by using this technology.

 

As DAC can slow or minimize the rise in the levels of carbon dioxide, it also helps in the reduction of global temperatures. The researchers are hopeful about the DAC programs and they believe that if the DAC program commences in the year 2025 with almost 1.2 to 1.9% investment of global gross domestic product (GDP) each year, it will be able to remove nearly 2.2 gigatons of CO2 by the year 2050 and about 13 to 20 gigatons by the year 2075. The DAC program would remove cumulatively 570 to 840 gigatons of carbon dioxide by 2100. The amount is enough to fulfil some targets of the Paris Climate Agreement.

Even with such commitment and enormous expenditure, though, there are probabilities that the average global temperatures will increase at least 2.4 to 2.5 degrees Centigrade if global greenhouse gas emissions persist at the present trajectories. That is why even with war-scale programs, conventional techniques of carbon mitigation like renewables are indeed important. According to one renowned climate scientist of India, ‘‘DAC undoubtedly is an effective technology, but for a drastic reduction in CO2 emissions, it should be used with the range of other climate change policies.’’

Here governments of all nations should play a significant role to make the DAC programs successful. Businesses and big industries also should come forward to make sustained investments in it. To scale up the deployment of this new technology, developing companies like Climeworks AG, Global Thermostat, Carbon Engineering, etc. are establishing associations with many of the largest engineering and energy firms. An increasing number of top companies and renowned corporations like United Airlines, Microsoft, etc. are making investments in DAC start-ups.
