A group of campaigners will march through St Peter Port tomorrow (6 November) as the COP26 climate summit reaches the end of its first week.
Organisers say the event will link up with other peaceful marches around the globe.
Helen Quin from the Clean Earth Trust says the island's politicians have laid out some good proposals but now they have to follow through.
"In Guernsey we need to see some actionable changes in alignment with the climate change policy and action plan, and in support of the strategy for nature.
The plans are, at the moment, still quite loose but there are some great ideas in there and we just need to see some commitment to getting them done.
We need to see supportive legislation for our community to transition into a new way of living and education on the impacts of climate change on Guernsey as a community, specifically."
Whilst Helen is hopeful that change will come from the global climate summit, she says the way some presidents and prime ministers travelled to Glasgow was wrong.
"With these issues there's a great level of hypocrisy happening - a lack of integrity in terms of the work that actually needs to be done.
Seeing our world leaders turn up to COP26 in their private jets is the problem, you know, people aren't taking this seriously."
The march will start in Market Square around midday, ending at the Candie Gardens at 2pm.
