Ravensdown says it will be ready if agriculture is brought into the Emissions Trading Scheme in 2015.
The deadline for fertiliser importers and manufacturers to register with the scheme, along with several other rural industries, was Tuesday, 31 January.
Those businesses must now collect data to calculate their yearly emissions, so they can file emissions returns.
But they won't pay for emissions unless farming is brought into the scheme, which under current legislation won't be before 2015.
Strategic development general manager Richard Christie says Ravensdown is preparing for that.
If farming is brought into the scheme, Mr Christie said the extra costs for Ravensdown will likely flow-through to farmers by way of higher fertiliser prices.
