Nottingham has managed to slash its carbon pollution in half in just under two decades, the city council says.
The authority says working together with businesses and residents amid the accelerating climate crisis has been critical to reducing the figures.
And the council also says the Green Rewards mobile app, which rewards people for turning off lights or using public transport instead of their cars, has alone cut carbon pollution equivalent to 300,000 miles travelled by car since its launch in October 2021.
