Adaptation
Climate change adaptation refers to any process or action taken to increase the resilience of people, infrastructure, communities, and ecosystems, allowing them to better adjust to the impacts of a changing climate and prepare for future impacts.
Asset Class
This is a grouping of infrastructure by form, such as in fleet and public transit, or of function, such as water facilities, that collectively contribute to the provision of core services to a community. On Climate Insight, infrastructure is grouped into the following asset classes - Buildings and Housing, Fleet and Public Transit, Green Infrastructure, Solid Waste, Transportation, and Water.
Baseline Emissions

Ethno-Cultural Composition
On Climate Insight, ethno-cultural composition is one of the themes or dimensions of the Social Vulnerability Index relating to the community make-up of immigrant populations and those self-identifying as visible minorities.
Expected Useful Life
On Climate Insight, expected useful life is the length of time the equipment/infrastructure is expected to last before requiring major maintenance, retrofitting, or replacement. This can be aligned with a manufacturer's warranty, or industry averages.
Extreme Heat
Extreme heat is a hazard that is defined as a prolonged period of temperatures that are above the average high, or more humid than the average. The definition of extreme heat may vary by region because of each location’s specific averages. For further information on specific thresholds, refer to Environment Canada.
Fleet and Public Transit
This infrastructure type /asset class refers to all motorized mobile vehicles and equipment, including government-owned/operated trucks, passenger vehicles, parks maintenance equipment, as well as buses, trains, or ferries.
Flooding
Flooding is a hazard that occurs when an area of dry land is partially or completely inundated. This can come from a number of sources including extreme precipitation (pluvial flooding), inland or fresh water bodies (fluvial flooding), seawater (coastal flooding), and groundwater.
Fuel Switching
A mitigation option category that includes any action that involves switching to low or zero carbon fuels/energy (eg. renewable energy systems, electric vehicles, etc.).
Global Warming Potential
All greenhouse gases (GHGs) are not equal. Each one has a unique atmospheric lifetime and heat-trapping potential. The Global Warming Potential (GWP) metric examines each greenhouse gas’s ability to trap heat in the atmosphere compared to carbon dioxide (CO2). We measure this over a specified time horizon. Often, we calculate GHG emissions in terms of how much CO2 is essential to produce a similar warming effect over the chosen time horizon. This is the carbon dioxide equivalent (CO2 eq) value. We calculate it by multiplying the amount of gas by its accompanying global warming potential (GWP). The Intergovernmental Panel on Climate Change (IPCC) provided 100-year GWPs in its Fifth Assessment Report. (Government of Canada)
Green Infrastructure
On Climate Insight, this infrastructure type/ asset class includes natural and hybrid solutions. Green Infrastructure is the natural vegetative systems, engineered and built features, and green technologies that collectively provide society with a multitude of economic, environmental and social outcomes (Click here for a visual illustration of the infrastructure and solution types).
Grey Solution
Climate Insight defines grey solutions to be any infrastructure options that are made exclusively of engineered materials such as concrete and steel (Click here for a visual illustration of the infrastructure and solution types).
Hazard
Hazard refers to the possible, future occurrence of natural or human-induced physical events that may have adverse effects on vulnerable and exposed elements. It can be thought of as the type of stressor or the natural phenomenon that may potentially threaten green, grey or hybrid infrastructure. On Climate Insight, we have used the term hazard to refer to climate-related physical events as well as their physical impacts, where appropriate.
Hybrid Solution
Climate Insight defines hybrid solutions to be any infrastructure option that incorporates elements of grey infrastructure to enhance or support natural infrastructure and/or the use of ecosystem processes. Hybrid solutions encompass enhanced and engineered assets, and are synonymous with low-impact development (Click here for a visual illustration of the infrastructure and solution types).
Immediate Vicinity
This selection includes both direct alterations to the asset and any options that can be implemented within the site's property boundaries
Indigenous Community
Self-governed First Nations, Inuit, or Metis community.
Infrastructure
The managed elements of interrelated systems that provide goods and services essential to enabling, sustaining or enhancing the living conditions of human communities. Infrastructure systems consist of built infrastructure, natural infrastructure, and the enabling environment. The guidance provided on Climate Insight is geared towards municipally owned and/or managed public infrastructure. Infrastructure types referred to in Solutions results refer to the infrastructure that the option increases resilience or reduces net emissions for.
LCA (Life Cycle Assessment)
A tool that assesses the environmental impacts of a project associated with all the stages of its life.
Likelihood
In the context of climate change risk assessments, likelihood refers to the chance of a hazard happening. Likelihood may be measured, determined qualitatively or quantitatively, and expressed in general terms or mathematically.

Low Carbon
On the Climate Insight Map, low carbon is an infrastructure type related to the Canadian Energy transition, including industrial biomass power generation, EV charging stations, wind turbines, and solar power facilities.
Low Carbon Resilience
Low Carbon Resilience is a lens used to coordinate and co-evaluate adaptation and mitigation strategies to reduce both emissions and vulnerability. Green Infrastructure and Nature-based Solutions support LCR as they both address hazards (through water management, cooling, erosion control, etc.) while also sequestering carbon through natural processes. Technical LCR solutions would include those that provide protections against one or more climate hazards while also reducing net emissions through energy efficiency, fuel switching, or offsets.
Major Retrofit
Involves a change or replacement of part/all of the infrastructure involving significant redesign, reconfiguration, and/or reengineering.
Minor Repairs
Considered to require no engineering or design changes, and can be done as part of normal operations.
Mitigation
Climate change mitigation refers to any action that limits or prevents greenhouse gas emissions from entering the atmosphere, as well as any enhancing activities that remove these gases from the atmosphere (carbon sequestration).
Moderately Complex Upgrades
Refers to additions or upgrades requiring minor design/engineering changes.
Natural Solution
Climate Insight defines a natural solution to be any infrastructure option that exclusively uses preserved, restored, or enhanced ecosystem features and materials (eg. water, native species of vegetation, sand and stone, etc.) to deliver beneficial community services and infrastructure outcomes. Encompasses all green infrastructure/assets (Click here for a visual illustration of the infrastructure and solution types).
Nature-Based Solution
Actions to protect, manage and restore natural or modified ecosystems, which address societal challenges, effectively and adaptively, providing human well-being and biodiversity benefits. NbSs pertain to natural and enhanced infrastructure/assets (Click here for a visual illustration of the infrastructure and solution types).

Quantitative Tools
An approach requiring numerical scoring or ranking using an established framework and hard data (e.g., historical climate and weather data, utility data, modelling/projections). Typically involves subject-matter experts (from a given sector or geographic location), as participants need to have a thorough and comprehensive understanding of the subject matter so that they can be confident in assigning numerical values.
Remote Community

Remote Community
A community that is more than 1.5 hours from the nearest urban centre.
Residential Instability
On Climate Insight, residential instability is one of the themes or dimensions of the Social Vulnerability Index relating to the tendency of neighbourhood inhabitants to fluctuate over time, taking into consideration both housing and familial characteristics.
Resilience
The capacity or ability to anticipate and cope with shocks and to recover from their impacts. In the context of climate change, it is the capacity of a system to prepare for, respond to, and recover from the impacts of hazardous climatic events while incurring minimal damage to societal wellbeing, the economy, and the environment.
Risk
The probability of harmful consequence or expected loss resulting from the interaction of a hazard with the built environment. Level of risk is determined by the characteristics of a hazard - its frequency/likelihood of occurring, and the potential consequences of it occurring. Consequences are dependent on the vulnerability of infrastructure/assets and people who may be impacted, as well as their level of exposure to the hazard itself.
Risk Assessment
The process in which the risk of a system (infrastructure/asset, community, etc.) to climate hazards is calculated. Involves the assessment of vulnerabilities, exposure and climate change hazards and their likelihoods and consequences.
Rural Community
Low density territory, lying outside of population centres often with high areas of natural, forestry, or agricultural lands.
Situational Vulnerability
On Climate Insight situational vulnerability is one of the themes or dimensions of the Social Vulnerability Index relating to variations in socio-demographic conditions in the areas of housing and education, while taking into account other demographic characteristics.
Social Vulnerability Index
In general, a Social Vulnerability Index (SVI) is an empirical tool that combines variables to measure the relative susceptibility of a specific subset of the population within a defined geographical boundary. A SVI combines the socio-economic variables that either directly or indirectly impact an individual’s or household’s vulnerability using proxy data. The analysis results in numerical scores, which are categorized into 1-5 levels. (Reference: Partners for Action. (2024). Inclusive resilience: A socio-economic vulnerability index(SoVI) to map flood risk for targeted communications and disaster risk reduction. Waterloo, Ontario: University of Waterloo.)
On Climate Insight the Social Vulnerability Index represents the Canadian Index of Multiple Deprivation (CIMD). This index consists of variables such as income, newcomer status, age, home ownership, etc. and is taken from Statistics Canada data.
The CIMD is based on four dimensions of deprivation, which have been included as additional standalone and with climate data in bivariate layers on the map.
These additional dimensional layers are:
- Residential instability
- Economic dependency
- Ethno-cultural composition
- Situational vulnerability
See the specific definitions for each of these terms and the Data and Methodology page for more information.
Solid Waste
Fixed infrastructure and assets used to manage, sort, collect, store and dispose of municipally generated waste. Excludes fleet assets and the physical buildings that house operations.
Examples: garbage cans, landfills, incinerators, recycling or composting facilities
Stormwater Infrastructure
Any asset that supports the transport and management or treatment of runoff water from rain or snow to redirect it to either local waterways, storage and retention, or a wastewater treatment plant.
Thermal Efficiency
Any option involving reducing energy losses with improved thermal efficiency (includes building envelope, process heat, etc.)
Tightly Scoped Risk Assessment
A tightly scoped risk assessment approach is one where the assessment is carried out with a given thematic or focus area (eg. a specific asset, asset class, service area, or entire system) or one which is focused on a single hazard category. Generally faster to complete than a comprehensive risk assessment as the number of climate parameters and individuals needed to be involved are limited.
