Elimination of CO2 from atmosphere is no longer optional!

The pressing question going into the Glasgow climate conference is whether big economies can reduce emissions enough by 2050 to achieve a carbon-neutral world in which humanity no longer emits planet-warming gases. Tools and techniques to extract CO2 directly out of the air are less well-publicized, but they are rapidly rising on the climate agenda.

Even skeptics agree that meeting the Paris Agreement objective of keeping global warming below two degrees Celsius will be impossible without carbon dioxide removal (CDR), often known as “negative emission.” Glen Peters, the research administrator of the Centre for International Climate Research, said, “We need extreme, radical effusions reductions, and on top of that, we require some CDR.”

CO2 can be extracted from thin air in one of two ways.

One option is to increase nature’s carbon absorption and storage capability. Forest restoration, mangrove restoration, large-scale tree planting, and growing carbon uptake in stones or the ocean are all instances of “nature-based answers,” which are hotly debated. The second way, perceived as direct air capture, involves chemical procedures to remove CO2, recycled or stored in porous rock formations, disused coal beds, or saline aquifers for future use.

BECCS (bioenergy with carbon capture and storage) is a hybrid of the two systems. Biofuels are created from wood pellets or other biomass, which is then burned to power turbines. As a result, CO2 emitted is nearly balanced by CO2 absorbed during plant growth. However, the process becomes a net-negative technique when carbon dioxide from the power plant’s exhaust is siphoned off and stored underground.

For a few reasons, yes.

Even if the planet reduces carbon pollution by three, four, or five percent per year, several industries, such as cement and steel manufacture, long-haul aircraft, and agriculture, are anticipated to be emitting at current levels for decades. “We have simulations, but no one knows what we’ll need in 2050,” said Oliver Geden, a senior researcher at the German Institute for International and Security Affairs and a CDR expert.

“Residual emissions will exist, and the numbers may be substantial.” There’s also an additional explanation. No matter how aggressively greenhouse gases are reduced, the 1.5C threshold will be broken in the future decades, according to a statement published in August by the United Nations’ Intergovernmental Panel on Climate Change (IPCC).

CO2 remains in the atmosphere for generations, so removing some of it by 2100 will be the only way to fix Earth’s average surface temperature back under supervision. BECCS was consolidated into IPCC climate standards more than a decade ago as the supposedly most affordable kind of hazardous radiation, but it has seen little progress since then. “I don’t think there’ll be a BECCS boom,” Geden mentioned.

A peer-reviewed plan in 2019 to slash surplus CO2 by planting a trillion trees created widespread interest in the media and between fuel and oil firms, making afforestation offsets a fundamental pillar of their initiatives to meet the Paris Treaty’s goals. Experts, however, slammed the plan, claiming that it would necessitate converting twice as much land in India to monoculture tree farms.
