To address the climate change challenge, areas of everyday life that could be regulated are, for example, 1. eating less or no meat (reduce meat consumption) and dairy, 2) driving and flying less, and 3) switching to renewable energy.

What are the existing laws available in the UK and potential laws that can be put into effect in the UK to address the climate change challenge focusing on the three areas of everyday life mentioned above?

Please provide details and consider the consequences.

Thanks.
