Transportation Infrastructure and the Environment

The City of Calgary is committed to achieving community sustainability and the design and construction work managed by Transportation Infrastructure (TI) is aligned with The City's Environmental Policy.

  • Construction projects and contractors comply with environmental legislation and established standards.
  • Opportunities are pursued to engage, collaborate and partner with other City business units, levels of government and organizations on programs and initiatives that benefit the environment.
  • Strategies are developed and implemented to promote natural resources conservation, prevent pollution and reduce water consumption.
  • Continual improvement of TI's environmental initiatives and practices described above is facilitated by its environmental management system that is regularly audited and registered to the ISO 14001 International Standard.

Environmental Initiatives

Contractor environmental responsibilities

Contractors working for TI on City of Calgary projects must review and sign the Contractor Environmental Responsibilities Package (CERP) prior to starting work. The CERP document outlines the City's Environmental Policy, and informs the contractor of City expectations to protect the environment and comply with all environmental laws and regulations.

Environmental Construction Operations (ECO) Plans

Construction projects having the potential to affect the environment all have plans in place to prevent or mitigate impacts. ECO Plans consist of written protocols, procedures, and management practices combined with site drawings that indicate how contractors will minimize adverse effects resulting from specific construction activities on a given site. They are reviewed for completeness by the City corporate environmental and safety management group. Once implemented at the start of construction, there are routine site inspections to ensure compliance.

Waste reduction and diversion from the landfill

Consistent with City Council priorities and initiatives, TI actively works with its contractors to promote the reduction, reuse, and recycling of waste materials on construction site in order to reduce the quantity of material being disposed of in landfills. Waste materials are sorted by waste stream on construction sites, with significant quantities (in the order of thousands of tonnes, per site) of concrete, asphalt, fill, wood, cardboard, steel and plastic being reused and recycled.

Energy Efficiency and GHG Reduction

The Projects being designed and built by TI typically don't include the types of buildings and facilities to which the Green Building Council's LEED (Leadership in Energy Efficiency and Design) standards apply. However, new C-Train stations are being designed in general conformance with such standards and sustainability principles to include passive solar, reduced and recycled material content, and other design features oriented to conserve and improve energy efficiency.

More broadly, TI has the mandate to design and build the elements of a transportation system that enables more sustainable land use and mobility as envisioned in Plan It Calgary, consistent with The City's sustainability principles. In this way TI directly responds to issues of air quality and climate change, including greenhouse gas (GHG) reduction, while enabling citizens to reduce their own ecological and carbon footprint.
