Madam Chair, to begin, I would like to confirm that we are committed to real action to reduce greenhouse gas emissions from our buildings, as is outlined in my mandate letter. We have opportunities here, and we want to seize these opportunities and demonstrate leadership.
This past year alone, we reported a 57.6% reduction in greenhouse gas emissions from our buildings, as compared to the baseline laid out in 2005 and 2006. This is a result of important actions to improve buildings' energy efficiency, electricity grid improvements and the procurement of renewable energy credits. A decrease of 19% of the remaining emissions is expected by 2025 through the procurement of clean electricity. That is the national clean electricity initiative.
A decrease of 40% of the remaining emissions is expected by 2025, by modernizing the heating and cooling systems for up to 80 buildings in the national capital region. This is referred to as the energy services acquisition program. Additional greenhouse gas emissions reductions are expected as we continue to modernize buildings.
These ongoing actions, in conjunction with achievements to date, will lead us towards achieving over 82% of greenhouse gas emissions reductions by 2025 and put us in a very good position to achieve net-zero carbon by 2030 in our buildings portfolio.
We also have the Buy Clean strategy. As outlined in my mandate letter, we are committed to reducing the carbon footprint and encouraging green procurement strategies. This includes strengthening federal procurement practices to prioritize reusable and recyclable products in support of our goal of zero plastic waste.
We will also work with our colleagues to introduce a new Buy Clean strategy to support and prioritize the use of made-in-Canada low-carbon products. Protecting our planet is a top priority for our government, and we will continue to do our part in promoting ecofriendly practices.
We also have made efforts on the electric vehicle front. We are committed to greening government at all levels of procurement. As the manager of the government fleet, we have standing offers for light-duty vehicles that include electric, hybrid and plug-in hybrid vehicles.
In the past three years, we have procured 1,187 zero-emission and hybrid vehicles. We will continue working with industry to ensure we are finding new ways to support green procurement opportunities.
