Brighton and Hove is the most sustainable city in Britain. That's the conclusion of our new report, 'The Sustainable Cities Index'.

The report comes at a time when the race to be a truly ‘sustainable city’ is increasingly competitive, with Manchester determined to become 'the Greenest City in Britain by 2010’, Bristol wanting to become a ‘Green Capital’ and London aiming for nothing less than the status of ‘most sustainable city in the world’.

Aiming to cut through the rhetoric, the new report brings rigour to the debate by using current data to determine who’s sustainable and who’s not. In it, each of the UK’s 20 largest cities are analysed according to three criteria – their ‘environmental impact', ‘quality of life’ and ‘future proofing’ – and given an overall ranking which summarises the results.

The data reveals that Brighton and Hove is the most sustainable city followed by Edinburgh in second place and Bristol in third. Liverpool comes bottom of the list, after Hull in 18th place and Birmingham in 19th.

In the UK, around nine in ten people live in towns and cities. Globally, we are now a majority urban world. We have no choice but to learn to live together in sustainable ways in cities. This will mean providing a high quality of life for all residents. It will also mean reducing the wider environmental impact of cities. Forum for the Future chose three baskets of indicators against which to rank the cities.

• The Environmental Impact of the city – the impact of the city on the wider environment in terms of resource use and pollution
• The Quality of Life for residents – what the city is like to live in for all its citizens.
• Future Proofing – how well the city is preparing itself for a sustainable future.

Forum selected these index categories to reflect the sustainability of each city in a fair and balanced way. We used a total of 13 indicators, spread across the three baskets. The indicators use existing data on aspects of performance on which cities are already expected to make improvements. We intend to measure these indicators year-on-year.

Commenting on the findings of the research, Peter Madden CEO of Forum for the Future said:
“We are an increasingly urban world. Britain, with its strong civic tradition, should be leading the way in sustainable city-living. We hope this index will make our cities better places to live, with a lower overall impact on the environment. We also hope it will encourage some healthy competition amongst our big cities to see who is greenest.”

Commenting on the city’s position at the top of the rankings, Brighton and Hove City council leader Brian Oxley said:
"It's really good that council policy on this is actually translating into eco-friendly measures and that these have been recognised. These range from higher than average bus use to new the development near Brighton Station achieving the Ecohomes Excellent rating. Although we're only one city, we are a famous place and hopefully we're helping spread the message that acting locally could make the difference globally."
