Climate Change

A long-term shift in the statistical distribution of weather patterns, including averages and variability, driven largely by human emissions of greenhouse gases since the industrial era.

Related: Greenhouse Effect, Global Warming
Greenhouse Effect

The process by which certain atmospheric gases trap outgoing infrared radiation, warming the planet's surface and lower atmosphere above the temperature they would otherwise have.

Related: Climate Change, Greenhouse Gas
Greenhouse Gas (GHG)

Any atmospheric gas, such as carbon dioxide, methane, or nitrous oxide, that absorbs and re-emits infrared radiation and thereby contributes to warming of the climate system.

Related: Greenhouse Effect, Carbon Dioxide Equivalent
Global Warming

The observed rise in average global surface temperature, conventionally measured against a pre-industrial baseline, that results mainly from accumulating greenhouse gas concentrations.

Related: Climate Change, Climate Sensitivity
Climate Sensitivity

A measure of how much global average temperature rises in response to a given increase in greenhouse gas forcing, commonly expressed as warming per doubling of atmospheric carbon dioxide.

Related: Global Warming, Climate Scenario
Carbon Dioxide Equivalent (CO2e)

A common unit that converts emissions of different greenhouse gases into the amount of carbon dioxide that would produce the same warming over a stated time horizon.

Related: Greenhouse Gas (GHG), Global Warming Potential
Global Warming Potential (GWP)

A factor expressing how much heat a gas traps over a chosen period, typically 100 years, relative to carbon dioxide, used to aggregate emissions into a single comparable figure.

Related: Carbon Dioxide Equivalent (CO2e), Scope 1 Emissions
Sustainability

Meeting present needs without compromising the ability of future generations to meet theirs, balancing environmental integrity, social equity, and economic viability over the long term.

Related: Sustainable Development Goals, Triple Bottom Line
Sustainable Development Goals (SDGs)

Seventeen globally agreed objectives adopted by the United Nations in 2015, covering poverty, health, climate, and ecosystems, used as a framework for aligning finance and business with social and environmental outcomes.

Related: Sustainability, Impact Investing
Triple Bottom Line

An accounting perspective that evaluates organisational performance across three dimensions: profit, people, and planet, rather than financial results alone.

Related: Sustainability, ESG Factors
ESG Factors

Environmental, social, and governance criteria used to assess how an entity manages sustainability-related risks and opportunities alongside conventional financial analysis.

Related: Sustainability, Materiality
Double Materiality

The principle that a firm should report both how sustainability matters affect its financial performance and how its activities affect people and the environment.

Related: Materiality, Climate-Related Financial Disclosure
Physical Risk

The potential for harm to assets, operations, or supply chains from climate hazards such as heatwaves, floods, droughts, storms, and sea-level rise, often split into acute and chronic forms.

Related: Transition Risk, Climate Risk Assessment
Transition Risk

The risk of financial loss arising from the shift to a low-carbon economy, including policy changes, technology shifts, litigation, and reputational or market sentiment effects.

Related: Physical Risk, Stranded Assets
Stranded Assets

Assets that lose value or become unviable before the end of their expected economic life, for example fossil fuel reserves that cannot be burned under decarbonisation policy.

Related: Transition Risk, Carbon Budget
Climate-Related Financial Disclosure

Reporting by organisations of the governance, strategy, risk management, and metrics used to manage climate-related risks and opportunities, following frameworks such as the TCFD recommendations.

Related: Double Materiality, Scenario Analysis
Green Bond

A debt instrument whose proceeds are earmarked exclusively to finance or refinance projects with clear environmental benefits, typically verified against recognised voluntary principles.

Related: Use of Proceeds Bond, Sustainability-Linked Bond
Sustainability-Linked Bond

A bond whose financial terms, such as the coupon, may change if the issuer fails to meet predefined sustainability performance targets, with proceeds not restricted to green projects.

Related: Green Bond, Key Performance Indicator (KPI)
Use of Proceeds Bond

A bond structure in which the issuer commits to allocate the raised funds to specified categories of projects, forming the basis of most green and social bond frameworks.

Related: Green Bond, Greenwashing
Greenwashing

Misrepresenting or exaggerating the environmental credentials of a product, activity, or organisation, misleading investors or consumers about actual sustainability performance.

Related: Green Bond, Sustainability Disclosure
Impact Investing

Investment made with the explicit intention of generating measurable positive social or environmental outcomes alongside a financial return.

Related: Sustainable Development Goals (SDGs), ESG Factors
Climate Risk Assessment

A structured process for identifying, measuring, and prioritising climate-related exposures, combining hazard, exposure, and vulnerability analysis to estimate potential losses.

Related: Physical Risk, Climate Scenario
Climate Value at Risk (Climate VaR)

An estimate of the potential financial loss to a portfolio or asset from climate-related risks at a given confidence level and time horizon, adapting conventional value-at-risk methods.

Related: Climate Risk Assessment, Stress Testing
Stress Testing

A technique that applies severe but plausible scenarios to a portfolio or institution to reveal vulnerabilities and capital adequacy under adverse climate or transition conditions.

Related: Climate Scenario, Climate Value at Risk (ClimateVaR)
Climate Scenario

A plausible, internally consistent description of future greenhouse gas pathways and associated socioeconomic and physical conditions, used to explore outcomes under uncertainty.

Related: Representative Concentration Pathway, Stress Testing
Representative Concentration Pathway (RCP)

A family of emissions and concentration trajectories used in climate modelling, each labelled by the approximate radiative forcing in watts per square metre reached by 2100.

Related: Shared Socioeconomic Pathway, Climate Scenario
Shared Socioeconomic Pathway (SSP)

A set of narrative socioeconomic futures describing population, economic growth, and technology, combined with emissions pathways to produce scenarios such as SSP1-2.6 or SSP5-8.5.

Related: Representative Concentration Pathway, Climate Scenario
Carbon Budget

The cumulative amount of carbon dioxide that can be emitted while keeping global warming below a specified temperature limit, given the near-linear relationship between cumulative emissions and warming.

Related: Net Zero, Stranded Assets
Net Zero

A state in which the greenhouse gases released into the atmosphere are balanced by removals over a defined period, achieved by deep emission cuts plus residual removal or offsetting.

Related: Carbon Budget, Science-Based Target
Science-Based Target

An emissions reduction goal aligned with what climate science deems necessary to meet the goals of the Paris Agreement, typically validated against recognised methodological criteria.

Related: Net Zero, Transition Plan
Transition Plan

An entity's time-bound strategy setting out how it will shift its business model, operations, and financing toward a low-carbon, climate-resilient future, including targets and capital allocation.

Related: Science-Based Target, Net Zero
Nature Risk

The potential for harm to an organisation from the degradation of ecosystems and biodiversity, and from its own dependencies on and impacts on natural capital.

Related: Biodiversity, Deforestation Risk
Biodiversity

The variety of living organisms and ecosystems, whose loss can disrupt ecosystem services on which businesses and communities depend, creating financial and operational exposure.

Related: Nature Risk, Natural Capital
Natural Capital

The stock of natural resources and ecosystem services, such as clean water, fertile soil, and pollination, that provide value to economies and can be degraded or depleted.

Related: Nature Risk, Biodiversity
Scope 1 Emissions

Indirect greenhouse gas emissions from the generation of purchased electricity, heat, steam, or cooling consumed by an organisation.

Related: Scope 1 Emissions, Scope 3 Emissions
