Nova Scotia has implemented two separate regulations to reduce emissions from the electricity sector and to improve the supply of renewable energy; together, these two regulations are expected to result in a reduction of 2,700 kt eq. CO in 2020. The Greenhouse Gas Emissions Regulations put in place a mandatory declining cap for GHG emissions from power plants. From a baseline of 10.2 Mt (2007), reductions are planned in incremental steps so that emissions total 7,500 kt or less by 2020 and are down to 4,500 kt or less. less by 2030. The total GHG reduction from the electricity sector from 2007 to 2030 will be at least 5,700 kt eq. CO. Under the Renewable Electricity Regulations, 40% of electricity supply must come from renewable sources by 2020. This will involve adopting a diverse mix of energy sources, including wind power, tidal power, solar power, hydropower and bioenergy. The impact of this mitigation measure is included in the estimate of the federal CO Emissions Reduction measure, resulting from amendments to the Coal-fired Electricity Regulations.
