"Today is a landmark day, as we turn climate ambition into law, and set out on a journey to net zero emissions. The extreme weather events around the world over the past month have shown us all that we must act quickly, to protect ourselves and our planet. Our immediate target of halving emissions by 2030 is challenging, but it is also an opportunity to transform our economy, create new jobs, protect our environment and build a greener and fairer future. We will all need to work together to achieve this, in renewable energy, active and sustainable travel, in business, agriculture and across government. But the signal we are sending today is that now is the time for action."
