I'll be happy to, Mr. Chair. That's a great question because that is exactly the challenge we face.
Every fleet has its own strategy. For vehicles on road, we're moving to zero-emission vehicles. I believe we have zero-emission vehicles for 30% of our on-road fleet. I think we're the number one in the Government of Canada. The Treasury Board can correct me if I'm mistaken.
The big one is ferries. That's the biggest source of emissions. A key part of the strategy is the procurement of two new ferries for the eastern ferry service. They're currently being designed and we're working with the shipyard to optimize design to reduce fuel consumption and carbon emissions as a result.
Those would be two examples of significant changes, both in terms of equipment and practice.
I'll actually just complete the example with the national aerial surveillance program. We run a fleet of aerial surveillance for environmental purposes. We're beginning, where we can, to swap a Dash 8 mission for a drone mission.
For example, with some of the whale surveillance off of New Brunswick—we're having a New Brunswick theme here today—we find that we're able to do some of those whale observation missions with drones, which is as or more effective than the Dash 8. Every hour on mission for the drone is a 96% reduction in carbon emissions in terms of the fuel burn relative to a Dash 8.
Where we can swap the mission, it's a great example of a management practice that reduces our carbon emissions quite significantly.
