Chris Packham launches legal challenge over UK’s watering down of climate policies

Campaigner claims ministers do not have legal right to alter timeline of carbon budget pledges at will

Chris Packham has filed a high court legal challenge to the UK government over its decision to weaken key climate policies.

The broadcaster and environmental campaigner has applied for a judicial review of the government's decision to ditch the timetable for phasing out petrol and diesel powered cars and vans, gas boilers, off-grid fossil fuel domestic heating and minimum energy ratings for homes.
