Norwich Pride will return for 2020 in July, and this year the organisers are changing the way they work with businesses and organisations for the event.
Every year, Pride gives opportunities to firms and groups to advertise to the LGBT+ market through sponsorships.
But for this year's instalment, those who wish to do so will be asked to sign a pride pledge before any collaboration can begin, with the aim of having them promote equality and diversity among their employees and members.
The pledge reads: "As an official supporter of Norwich Pride 2020, we pledge our business or organisation will be a safe, welcoming and friendly place for LGBT+ customers and staff.
"We will visibly support and promote equality for LGBT+ people, challenge homophobic and transphobic behaviour, and have clear reporting mechanisms for harassment and discrimination.
"We will ensure our staff are trained to understand the experiences of LGBT+ people and how to be a proactive ally."
Norfolk County Council became the first organisation to sign the pledge, and plan to display it in the foyer at County Hall.
Norwich Pride chair Jo Caulfield said: "We're really pleased to be launching the Norwich Pride pledge and to welcome Norfolk County Council as our first supporter and signatory.
"Our intention is that this pledge should give LGBT+ people across Norfolk the confidence that businesses and organisations who sign it are taking seriously the experience and needs of our community."
County councillor and cabinet member for communities and partnerships Margaret Dewsbury said: "We have absolutely no hesitation in signing the Norwich pride pledge - the work of Norwich Pride is vital, and we are proud to be their supporter and ally.
"We at the County Council can take a leading role in ensuring our county is a safe, welcoming and friendly place for LGBT+ residents to live and work and, as a major employer, are working hard to ensure we offer a supportive, understanding environment for our LGBT+ staff and recognise they contribution they make to Norfolk."
Norwich Pride said that 88pc of people giving feedback on last year's event stated that they would think better of a business if they know a brand is supportive of Pride.
