Net Zero again.

 Does carbon capture work?

If CCS can be done at a big enough scale, it may capture some emissions. But even though it has been talked about for a long time, there are still many environmental, political and economic issues with it. Because of these issues, it is not yet proven to be deliverable or cost-effective at the level needed.

Currently, carbon capture technology is not advanced enough to remove emissions directly from the air at any scale that would be useful.

Concerns about CCS

Many scientists believe CCS should only be used when emissions would be hard to reduce otherwise. For example, cement kilns, or other industries that need high temperatures, like glass production.

A number of top climate scientists have expressed concerns that CCS in the UK is being used inappropriately. They say that there’s little benefit in using CCS as a major part of the UK’s energy strategy, and that the focus should be on renewable energy and storage, energy efficiency and reducing demand.

A further concern is that functioning CCS has proved hard to deliver. And concentrating money and political energy on it, instead of genuinely clean solutions, will slow the transition to net zero.

Pros and cons of CCS

Supporters of CCS – mainly industries that emit lots of carbon – claim that the process works in theory, it just needs to be put into practice. But sceptics point to the fact that this has failed to happen successfully over the past three decades.

 is considering using Biofuels.

Politicians and corporations have been promoting the large-scale production of fuels from crops. They claim these biofuels are an easy solution to climate change. But in reality they just ravage more of the planet's natural resources.
