What Net Zero Means in Practice A quick look at the facts and it soon becomes clear that reaching carbon emissions of net zero will be extremely difficult and will require cast iron government policies and political will. For the UK to reach net zero emissions clean energy production from solar, wind and possibly nuclear would have to be quadrupled. All boilers, most of which run on gas, would have to be replaced by hydrogen and electric powered heat pumps and from 2025 no new homes could be connected to the gas grid. All petrol and diesel cars would have to be banned from sale from 2035 at the latest, although flights would not be banned. A fifth of all the farmland in the UK would need to be set aside for carbon capture, either woods and forest or restoration of peat bogs or for growing biofuel crops and a total of 1.5 billion new trees would need to be planted.]]>
