The labelling program is a federal initiative, I believe, but states and local governments reference it in their legislation. I'm not an Australian policy expert, so I don't know all the ins and outs of how they've used the program. I do know that they report that about 82% of the office buildings in Australia are part of the program now. It is voluntary, but I think there is some specific state and local legislation that does reference it, which makes providing energy information to tenants, for example, mandatory. Using their national labelling system is one way they can do that.
