CSA Group, with support from the Standards Council of Canada (SCC), published CSA D700, Climate Change Adaptation and Resilience for Transit and Passenger Rail Systems, a new National Standard of Canada designed to help transit agencies and passenger rail operators assess climate-related risks and plan infrastructure and operational improvements.

The standard provides a framework to identify vulnerabilities, prioritize risks, and develop adaptation strategies to address flooding, extreme heat, severe storms, freezing rain, and other climate-related events that can affect transit infrastructure and services.

“Transit and passenger rail systems are critical to the movement of people and the functioning of communities and economies across Canada,” said Ana-Maria Tomlinson, Director, Standards Development, CSA Group. “CSA D700 gives organizations a consistent approach to understanding climate-related vulnerabilities, evaluating risks, and developing adaptation strategies that can help maintain reliable transportation services in a changing climate.”

Building on Existing Standards

The release follows broader efforts by CSA Group to develop more consistent standards for Canada's transit and passenger rail industry.

In a previous METROspectives interview, Tomlinson discussed CSA Group's work to establish a National Code for Transit and Passenger Rail Systems in Canada, including the challenges of applying different international standards to Canadian transportation projects.

During the conversation, Tomlinson explained that Canadian transit projects often rely on a combination of European, American, and other standards that were not necessarily developed to work together. CSA Group's national code initiative is intended to provide a more coordinated framework for applying standards across transit and passenger rail projects.

The initiative also emphasizes collaboration among transit agencies, regulators, manufacturers, engineers, and other stakeholders to develop standards that reflect industry needs.

CSA D700 addresses climate adaptation and resilience as part of CSA Group's broader standards development efforts. The new standard is designed to complement existing railway and transit standards rather than replace them.

It can be used alongside established standards and frameworks, including:

• CSA R114: Railway risk evaluation and assessment.
• CSA R122: Passenger railway safety indicators.
• CSA Z1600: Emergency and continuity management.
• ISO 14090 and ISO 14091: International guidance on climate adaptation and climate-related risk assessment.

According to CSA Group, the standard provides a common approach to incorporating climate considerations into infrastructure planning, operational decisions, and long-term investments.

Key Areas of CSA D700

CSA D700 addresses three primary areas of climate adaptation and resilience planning:

• Climate Vulnerability and Risk Assessment: Provides processes for identifying climate hazards, evaluating system vulnerabilities, assessing an organization's capacity to adapt, and prioritizing risks.
• Adaptation Planning and Decision-Making: Offers guidance for identifying and evaluating resilience measures, comparing alternatives, prioritizing investments, and documenting decisions.
• Implementation, Monitoring, and Continual Improvement: Addresses implementation planning, performance monitoring, evaluation, reporting, communication, and updating adaptation plans as new climate information becomes available. The framework helps organizations incorporate climate-related risks into existing planning and asset management practices while supporting the continuity of transportation services.

Supporting Transit and Passenger Rail Planning

CSA D700 is intended for transit agencies, passenger rail operators, infrastructure owners, planners, engineers, asset managers, consultants, and other organizations involved in developing, operating, and maintaining transportation systems.

According to CSA Group, the standard supports decisions on infrastructure investments, service continuity, and long-term adaptation planning.

The standard is now available in English and French through the CSA Group Store.
