About 160 people from seven local companies will be working on eight projects across the district on Friday, May 16.
Jocelyn Hunter, Calderdale Cares manager, said: "Over the past three years almost 5,000 volunteers from 150 businesses nationally have cleared scrubland, planted trees and mended fences to help schools and community groups.
"This year is bigger than ever, with action in 22 cities and towns across the country as we ask people to do something about our changing climate and tackle projects with environmental themes."
All the projects have been identified by the community or school pupils. At Bolton Brow Primary, Pennine Housing 2000 volunteers will clear a site for a wildlife area.
Employees from First will visit Christ Church Primary, Sowerby Bridge, to construct a greenhouse, dig out a patch of ground and paint outdoor equipment.
At Luddenden Foot Primary volunteers from RSA – formerly Royal and SunAlliance – and Action Halifax will set up a vegetable garden, plant flowers to spell out "Welcome" and clear an overgrown area.
At Old Earth Primary, Elland, Marshalls employees will set up compost bins and develop a path, which will be used as a trim trail and wildlife walk.
Calderdale Council workers will develop wildlife garden paths, clear a seating area and another plot for growing plants at Triangle Primary, Sowerby Bridge.
HBOS will send volunteers to three sites. They will work with the Friends of Nutclough Woods in Hebden Bridge on projects to help support wildlife and make the woods more pleasant.
As part of the Renaissance Project and to celebrate Calder Future's 10th anniversary, volunteers will work along the Copley canalside, clearing and removing old fencing along the walk way.
And at Rawson School, Boothtown, Halifax, HBOS volunteers will finish planting an area which has already been revamped by Marshalls.
Most materials for the projects have been provided by the Countryside Service, by Marshalls and by the volunteers who will be working on the day.
However, any contributions of skips, membrane, woodchip or top soil would be welcome.
