Partnership agreed for three-year period
IFGL says it's working with the event's organisers to try and give it a greener approach.
This includes encouraging walkers and support teams to think about what they bring on the day to minimise rubbish and the company has also helped the event introduce a new waste disposal system.
Walkers are also being provided with collapsible, reusable cups for water which can be refilled around the course.
IFGL's Marketing Director, Simon Barwell, says they're proud to be playing a part in making the major Island event more environmentally-friendly.
The Parish Walk is one of the Island's leading mass participation events, attracting between 1,200 and 1,500 participants each year.
This year's event is scheduled to take place on Saturday, 18 June.
