I would say two things on that front, one on the structure of our mandate and then secondly on our investments in the energy transition.
First of all, I think the country has been really well served by the simplicity of the mandate we were given back in the CPPIB Act in 1997, which is to maximize returns without undue risk of loss. Then it was left to a professional board of directors and management teams over the years to figure out how to do that.
What is the best portfolio we can find, whether in Canada or around the world, to achieve that objective? It's a very difficult objective. Managing money is not simple. It's very competitive. Having that clarity of purpose has made it at least slightly simpler for us to execute, and it has served really well, so we always have the interest of building value in the fund. That is the number one thing that drives what we do every day.
If you load in other complexities and objectives, then it becomes much more difficult, and there are obviously compromises and trade-offs. I think it's something that the country was very smart about—and people were very smart about—back in 1997 in setting up the fund this way. I think it has really proved itself over the years and is the envy of the world, frankly, as a simple, straightforward way to set up the objectives of the fund.
Having said all that, we do believe that climate change is happening, and we do believe it is a major risk, so for the last 12 years we've been focused on understanding the risk, and it's challenging. It's a very difficult risk to understand. We publish a sustainable investing report, “Investing Responsibly for CPP Contributors and Beneficiaries”, every October. It goes into some depth about how we are thinking about climate change and what we're doing with respect to it. I will give you just a couple of highlights around it, because it's a long topic.
The first is that every single major investment we make must take into account climate change risks and make sure that we understand those risks and what might happen to the company, what might happen to the asset, before we make the investment, and that we've been sufficiently compensated for it. For example, in the last year, we invested in a toll road in Indonesia. One of the major issues was, what will happen with climate change? What will happen with flooding? What will happen to the geography around that toll road as climate changes? If it changes [Technical difficulty—Editor]. Understanding the risks is really important.
The second thing is understanding overall, from a top-down perspective, what the risks are that we have in our portfolio and stress-testing the portfolio depending on whether we have faster shifts in climate or slower shifts in climate.
It's a complex area. It's one where we are determined to be at the forefront of understanding those risks and understanding where the opportunities lie around it, so that we can invest in those opportunities.
