If the Government of Canada can issue credible green bonds, there is literature and research out there that say you can save on the cost of capital. They estimate, if you have a credible issuance, that it's somewhere between one and nine basis points. That means for a $10-billion issuance, you save, on average, about $4.5 million a year.
It comes back to investors, but it has to be credible. It is not credible without a taxonomy.
