Resource Use

Infrastructure projects should implement specific actions to improve environmental sustainability by reducing resource consumption (e.g., energy, water, materials, etc.) and waste generation, and strive for no net loss and net positive impact. Resources are limited and a fundamental aspect of sustainability is to minimize their use, which in turn helps reduce project costs. Excellent opportunities exist and continue to be developed in terms of technologies, equipment and materials that improve efficiency and reduce use/consumption. A negative impact mitigation measure could be implemented in a more sustainable way, such as the use of more sustainable materials or approaches to erosion control and re-vegetation and enhancing road habitat connectivity. In order to maximize benefits, the selection of sustainable actions should consider the environmental context of the project (e.g., water or material scarcity, impacted watersheds or airsheds), project material usage and associated local costs, and sustainability priorities established by the government. It is never too late to implement environmentally sustainable actions, albeit the maximum benefits are likely obtained when actions are implemented at the project planning and design stage.
