In the statement the council said the Emissions Trading Scheme had been in place since 2008 as the Government's principal response to climate change.
The aim of the scheme is to give an incentive for people to reduce carbon emissions by charging for the amount of carbon their waste creates.
In 2016 it was announced the Government would phase out the subsidy offered to some businesses that reduced the amount they paid for each emission unit (NZU) produced (one metric tonne of carbon dioxide or other equivalent greenhouse gas).
Businesses across the country including landfill operators now have to pay 67 per cent of the cost per unit which will rise to 83 per cent in January 2018, with 100 per cent of the charges in place by January 2019.
Council general manager of infrastructure Stavros Michael said the costs were a form of taxation and were not considered part of the operating costs of landfills.
"Landfills are subject to two types of taxation - a waste minimisation levy which is fixed at $10 per tonne, and compensation costs for every tonne of waste through the purchase of carbon credits," Mr Michael said.
"The idea is that the costs are meant to be passed to the user [waste creator] to encourage them to reduce the amount of waste they produce. This is an opportunity for the public to look at ways to minimise the waste they produce and therefore reduce the need to go to the landfill."
Mr Michael said by increasing the landfill fees and recovering the costs from the users, council is able to shield the general ratepayer from paying extra rates
The market price for credits has been steadily rising during the past 18 months from about $5 to between $16 and $17 per unit.
One tonne of waste produces about 1.19 tonnes of carbon dioxide. Rotorua Landfill takes about 30,000 tonnes of waste each year.
This means that the landfill contractor must pay for 35,700 metric tonnes of carbon dioxide (35,700 NZU).
The statement said it was Waste Management's decision to increase the fees with approval from the council.
"Charging fees to use the landfill is the only way the contractor can recover the costs used to pay for things like carbon credits and to protect the general ratepayer," the council statement said.
"Irrespective of who operates the landfill the cost of running it will be the same. Charging higher fees at the landfill means that council does not have to charge ratepayers more in general rates."
The council said it was aware many people considered the cost of using the landfill one of the reasons people chose to illegally dump their waste.
"However, reducing the fees is not an available solution for council.
"Reducing fees would mean that council would need to recover costs from other places like the general rates. Keeping it as a user pays system means the community as a whole is not paying more.
"Often a lot of what is illegally dumped is items that can be placed in residential rubbish bins so council is working to educate the community on how to use the waste services that are already available.
"Other alternative ways to get rid of waste include community clean-up days that are often supported by council, or sharing a trailer or bins with your friends and family."
District councillor Charles Sturt has been a vocal advocate for reducing rubbish dumping in Rotorua.
"Nothing has been done to prevent it," he said.
"The costs of illegal dumping are already projected to go above last year, which was $200,000."
But Mr Sturt said he didn't think increasing the landfill cost would increase dumping.
"It's just crazy, there's no excuse, lazy people will do it regardless of cost," he said.
"I went to the public and asked what solutions they want to see and that is for one or two free landfill tickets per household."
The council said there were several reasons why a kerbside inorganic collection was not a viable option and a lot of councils are trying to move away from these practices.
"The cost of one inorganic collection could cost council around $500,000 to $1 million. This would need to be recovered through the general rates. A user-pays system means the general ratepayer is shielded from the cost of dealing with other people's waste."
It said "except for a select few" Rotorua's fees were cheaper (by the tonne) than a lot of other districts in the North Island.
