Of course, the term “sustainable” is quite subjective; the word “sustainable” does not define all of the concrete aspects or measures involved.
By and large, the intent is to have a project that will ensure a balance between economic potential and environmental repercussions, and provide future opportunities for the communities, which will be able to derive benefits from these projects for a longer timeframe than that offered by mines, for instance. If we invest in infrastructure, it will stay in place much longer than a mine would. We can also invest in workers' education, which is also something that will last much longer than a mine.
So we want to invest in a sustainable way in this type of project and there are examples of them everywhere.
