Alberta is preparing a rebate program to encourage homeowners to purchase energy-efficient appliances and help the province reduce greenhouse gas emissions.

Environment Minister Robin Campbell said Thursday the program would cost up to $30 million in its first year. He wants to make the announcement in early October.

The money for the program would come from a fund that large industrial companies pay into when they can't meet their greenhouse gas reduction targets.

The government would pay part of the cost of energy-efficient upgrades based on receipts submitted by homeowners.

A similar program in Alberta that ran between 2009 and 2012 issued more than 173,000 rebates worth more than $52 million.

The province has been under pressure from conservation groups to take new measures to help reduce Alberta's carbon footprint.

The Alberta Energy Efficiency Alliance says the province is the only jurisdiction in Canada or the United States that doesn't offer homeowners and businesses financial incentives to become more energy efficient.

Jesse Row, the alliance's executive director, said Campbell's plan would be a first good step.
