Visitors to The Forum learned how to be more environmentally friendly through a two-day festival in the city.
One Planet Norwich aimed to promote more sustainable ways of living and involved organisations from across the county.
People had the chance to learn about recycling, home energy efficiency and listen to a variety of guest speakers.
There were also various activities for children to enjoy, including a pedal-powered smoothie maker and Scalextric racing track.
Lord Mayor Brenda Arthur launched the festival on Friday by planting an oak tree in Chapelfield Gardens.
She said: 'This oak tree is a living symbol of what One Planet Norwich is all about. Which is promoting sustainable choices to ensure our city and our world remains a beautiful place for our children, grandchildren and beyond.'
Dr Hayley Pinto, from Climate Hope Action in Norfolk, was one of several stall-holders inside The Forum on Saturday and Sunday.
She said: 'There is a lot of stuff around sustainable living, but lots people don't know why it is important.
'As a population we need to be informed about what is happening in regard to climate change, and people don't realise how much it is impacting us already.'
Other stall-holders present during the festival included the Norfolk Master Composters and the RSPB.
Guest speaker Karen Cannard, who was an adviser to Hugh Fearnley-Whittingstall's 'Hugh's War on Waste', also gave a presentation on home recycling.
