The UK is moving forward with trials of mechanisms to draw carbon dioxide from the air as part of a drive to meet 2050’s net-zero emission target.

Whilst the goal is admirable, and the investment in clean energy that it requires is a positive step in the energy sector, scientists are still predicting that this action will not be enough to slow the quickening progress of global warming. This is coupled with the fact that achieving net-zero in the next three decades may not be possible due to failure in the past to limit the emission of carbon dioxide.
