"Clubs are usually cash-strapped and run by busy volunteers who don't have the time or money to make these changes.
"By being more efficient with resources, the club has less of an impact on the environment, too."
LiteClub's field teams travel New Zealand in a van stocked with LED lightbulbs, water saving devices, hot water cylinder wraps, pipe lagging and indoor waste sorting bins to help clubs with their recycling.
LiteClub has visited 10 Whanganui sports clubs in the past.
"Across these clubs, the LED lighting upgrades and hot water pipe insulation are calculated to free up $66,098 over the lifetime of the products installed, and prevent 58 tonnes of carbon emissions," Gerlach said.
"Thirty-eight waste sorting stations were also set up in clubrooms to make recycling more effective and easier for club volunteers to manage. Simple water saving devices installed in taps and toilets will conserve more than 300,000 litres of water each year."
The programme is funded by the Lion Foundation and local funders like the Whanganui District Council and Infinity Foundation.
