One idea is to remove carbon dioxide from the air and extract the carbon, though that’s an expensive process.

As power stations go, geothermal plants are “clean.” Instead of burning fossil fuels, they rely on steam or superheated water pumped from underground, which is why they tend to be sited in volcanically active areas. Still, as Aradóttir explained to me, they, too, produce emissions. With the superheated water inevitably come unwanted gases, like hyd

An especially profitable opportunity will involve reforming natural gas at the wellhead, where a large plant can strip out the hydrogen for shipment to wholesale markets via new or existing pipelines. Professor Robert Williams of Princeton University points out23 that the other product of the separation process, carbon dioxide, could then be reinje

However, offsetting is becoming considered an increasingly unsustainable practice because it bypasses the crucial activity of carbon emission reduction and can lead to global imbalances and inequalities resulting from the impact of offsetting projects (which will be covered in more detail later in this section). There are even those who argue that

It’s very unlikely any one category of technology, or any one natural approach, will scale enough. We should think of a portfolio across all the approaches outlined here, as well as more I didn’t discuss or have yet to be discovered.
