I can elaborate quickly.
One thing we are partnered with is a global air chiefs climate change collaboration. It's essentially a club of air forces that are working together to try to share best practices and work with one another to enable climate change reactions, and it does include some greening of our fleets. Some of it is, of course, reactions to climate change and humanitarian assistance types of elements. There's also a very robust discussion on synthetic aviation fuel, and we are using that in the RCAF to positive effect.
There are some greening efforts that I would say are embedded in different parts of the organization.
