Certainly. It's a terrific question.
I'll address some aspects, and Mr. Leduc may want to add.
With respect to what we call “sustainable investing”, I referenced that we have four, and now five, areas we're particularly focused on. Climate change has been one that we've been focused on for the last 10 years.
Most recently our head of sustainable investment was a member of the FSB's task force on climate-related financial disclosures. That work was completed last summer and announced at the G20 last summer by Governor Carney. We have committed to implementing that ourselves by fiscal 2021. One of the reasons is that we need sufficient disclosure from all of our portfolio companies to build up so that we understand what we have and the risks we have. We need more and more of those companies to adopt those disclosure mechanisms.
In the meantime we're very focused on continuing to implement stronger understanding of the risks that we're taking on in climate change, first from the bottom up, so we're developing a tool kit. We go into a lot of detail on it in the annual report. There is a tool kit that we're developing for each investment team so that they can address and understand the risk they're taking on in the investments they're making.
We're also doing a top-down assessment of all the risks we're taking on. We have a carbon footprinting tool that we're developing. There is no perfect tool in the world to do that today, but we are working with best practices around the world to develop our own proprietary tool. We're developing our own model for energy transition and the speed of that transition, which is critical to understanding the risks we're taking on, and beyond I would highlight that we now have a dedicated team investing in renewable energy. We have made a number of renewable investments here in Canada, in Europe, in India, and in Brazil in the last year, and we continue to commit to growing that investment. We mentioned a $3-billion number for where we expect that portfolio to grow.
Today we announced that we're issuing a green bond. I think we're the first pension fund in the world to issue a green bond, which we'll use to partially finance those investments.
