We've been talking with countries about embodied carbon, which is the carbon in construction materials. We essentially have to extract the materials, process them, then put them in our buildings. That has a carbon footprint.
We've been working with the U.S. Council on Environmental Quality and the General Services Administration in the U.S. to look at their equivalent to the greening government strategy, their executive order and the plans and processes they are putting in place. We're especially interested in partnering with the U.S., because a lot of our markets are North American.
