London CNN —  

Drastic restrictions on almost every aspect of people’s lives, from the cars they drive, the way they heat their homes, to the fridges they buy – even the food stored in them. That is the reality of what awaits us in 2050 if a UK government pledge to cut greenhouse emissions to “net zero” is to be met.

If it can do it, the country will become the world’s first major economy to stop contributing to climate change.

But the goal is extremely ambitious – the roadblocks massive.
