Why is it important for us to consider sustainability as we go forward with investments in infrastructure? I think the principles of sustainable development are fundamental to assuring that we are getting the best return on investment as well as looking after the environmental and social needs of today and going into the future.
At the heart of it, that's really why we need to consider sustainability with any projects going forward. Using tools such as Envision or any of the other rating systems that are out there helps through the planning stages, the design stages, and even through the operating stages to look at what the long-term impacts are and again, not just the financial benefits or the financial impacts, but the environmental and the social impacts.
