Well, we certainly want to be transparent, Yvonne, and it's a really important question actually, because at the end of the day, our strategy and the choices that we make around strategy are what's going to drive value for you as a BHP shareholder. Now, we have been very consistent in the strategy that we've been pursuing for a number of years now, and that strategy involves us wanting to have a portfolio of assets that are first and foremost in the right commodities. And by right commodities, we mean those commodities that are positively leveraged, so have a positive correlation to some of the big mega trends that are underway in the world around us. And so if we think about what's happening in the world in the coming decades, we'll have ongoing population growth, rising living standards, there's the big shift towards people living in more urban centers which tends to be metals-intensive, and we have the decarbonization thematic playing out as well. And so what we want is to be in commodities that stand to benefit greatest from those trends.
Secondly, we want to ensure that within those trends we're involved in commodities where we can generate significant margins. And David spoke earlier about the very strong margins that we have relative to our competitors. We want to own large assets where we can create value at scale, so for the same management effort we can create significant value for shareholders. And we want those assets to be sitting at the low end of the cost curve to ensure that they're resilient throughout the cycle, which is a point I mentioned earlier.
So against that backdrop, we've had an effort underway in the company to streamline the portfolio, and that's been underway for a number of years now. Most recently, we of course divested the oil and gas business to create a new company in Woodside. We've had an effort underway to optimize our coal portfolio, even as we then seek to grow in what we've termed future-facing commodities. And these commodities are potash, copper, and nickel, which we believe have very strong or stand to benefit strongly from the trends that I spoke about.
That's on the portfolio front. Now, of course, for every dollar that we invest in those assets, we want to ensure that we're returning maximum value to you, our shareholders. And so we do have a very strong and consistent focus on operational excellence as well. And then finally, social value. We believe that one of the things that will allow us to create and sustain high shareholder value over time is the way that we ensure we're creating value for all of those stakeholders who depend upon and support BHP. And so we do have a differentiated approach to social value where we try to embed that thinking into all of the decisions that we make as a company, such that we're pursuing greatest possible value for shareholders as well as in parallel creating value for the other partners that we engage with. And those three things—focus on operational excellence, having a differentiated approach to social value, and growing in future-facing commodities—are the sorts of things that are allowing us to create the strong returns that I mentioned earlier and which we believe give BHP a very strong shareholder value proposition going forward as well.
