A commitment to help workers in developing countries has led to Brighton and Hove being awarded Fairtrade City status.
Fairtrade offers coffee producers in the developing world a better deal
The sale of Fairtrade items, such as chocolate, cocoa and coffee, ensures a better deal and decent wages for the small producers.
The mayor of the Sussex city, Pat Drake, is receiving a certificate awarding the status on Friday.
She described it as a "massive and important achievement".
"Representatives from the council, NHS, schools, volunteer groups, farmers and businesses have been working tremendously hard to bring this about and are finally receiving the acknowledgment they deserve," she said.
Brighton and Hove was honoured by the Fairtrade Foundation following the achievement of five goals, which included ensuring the products were readily available and raising awareness of the scheme.
A spokesman for Fairtrade said the award would help bring the consumer and produce closer together.
To mark the occasion, banners have been hung in the streets of the city, and fun events and promotions are being held.
These include schools playing football games with Fairtrade footballs, and shops offering taster session promotions.
Brighton and Hove becomes the 25th of the UK's 66 cities to be awarded the mark.
