That is discussed in my mandate letter from the Prime Minister, and is a priority for me as minister to do my part to green government and reduce our carbon footprint. I discuss that with our department frequently.
We are developing a strategy to power federal buildings with 100% clean electricity where available by 2022. We're still in development of this plan, but we are already retrofitting buildings, converting our fleet of vehicles to electric and hybrid vehicles and charging stations and, as you mentioned, converting our electrical system to clean energy to reduce the government's GHG emissions.
In addition, I want to mention the energy savings acquisition program. Through this GHG emissions program, we've already cut by approximately 30% since 2005. We aim for a total reduction of 63% in the national capital region with completion of the energy services modernization in 2025.
It is a priority for us. We are working on it. It is complicated, complex and multipronged, but we are working very hard on this strategy.
