Scope 1 emissions

Direct greenhouse gas emissions from sources a company owns or controls, such as fuel burned in its own boilers, furnaces, and vehicles, reported in tonnes of CO2 equivalent.

Related: Scope 2 emissions, Scope 3 emissions, GHG Protocol
Scope 2 emissions

Indirect emissions from purchased electricity, steam, heat, or cooling a company consumes. They can be reported using location-based or market-based methods, which often produce materially different figures.

Related: Scope 1 emissions, Scope 3 emissions, GHG Protocol
Scope 3 emissions

All other indirect emissions across a company's value chain, including purchased goods, business travel, use of sold products, and end-of-life treatment. Usually the largest share for most sectors.

Related: Scope 1 emissions, Financed emissions, PCAF
GHG Protocol

The most widely used accounting standard for corporate greenhouse gas inventories, defining scopes, boundaries, and calculation guidance. It underpins most disclosure regimes and investor data requests.

Related: Scope 1 emissions, Scope 3 emissions, Science Based Targets initiative
Financed emissions

Emissions attributable to a financial institution's loans and investments, calculated by allocating a borrower's or investee's emissions in proportion to the capital provided. A category of Scope 3 emissions for banks and investors.

Related: PCAF, Scope 3 emissions, Carbon footprint of a portfolio
PCAF

The Partnership for Carbon Accounting Financials, an industry standard setting methods to measure and disclose financed emissions across asset classes such as listed equity, corporate bonds, mortgages, and project finance.

Related: Financed emissions, Carbon footprint of a portfolio
Carbon footprint of a portfolio

Emissions attributed to holdings, usually normalised by portfolio value or revenue, expressed as tonnes of CO2 equivalent per million dollars invested. Enables comparison across portfolios but is sensitive to methodology.

Related: Financed emissions, Weighted average carbon intensity, PCAF
Weighted average carbon intensity

A portfolio metric that weights each holding's emissions per unit of revenue by its portfolio weight. Widely used in reporting because it requires only revenue data and is less distorted by enterprise value swings.

Related: Carbon footprint of a portfolio, Implied temperature rise
Implied temperature rise

An estimate of the global warming consistent with a portfolio's or company's projected emissions pathway, expressed in degrees Celsius. Depends heavily on assumptions about future decarbonisation and coverage.

Related: Net zero alignment, Weighted average carbon intensity
Net zero alignment

The degree to which a company's or portfolio's emissions trajectory and capital plans are consistent with reaching net zero emissions by a specified date, typically 2050, under a stated scenario.

Related: Implied temperature rise, Science Based Targets initiative, Transition plan
Science Based Targets initiative

A body that validates corporate emissions reduction targets against climate science, requiring near-term and often long-term net zero commitments. Validation signals credibility but does not guarantee delivery.

Related: Net zero alignment, GHG Protocol
Transition plan

A company's documented strategy, actions, and capital allocation for moving its business to a low-carbon model, including interim targets, governance, and spending. Investors use it to assess credibility of climate commitments.

Related: Net zero alignment, Just transition, Stranded assets
Physical risk

The potential for harm from climate hazards such as floods, heatwaves, wildfires, and sea-level rise, affecting assets, operations, and supply chains. Can be acute, from events, or chronic, from gradual shifts.

Related: Transition risk, Adaptation, Climate scenario analysis
Transition risk

The financial risk from moving to a low-carbon economy, including policy changes, carbon pricing, technology shifts, and reputational or litigation effects that can reprice assets.

Related: Physical risk, Stranded assets, Carbon price
Stranded assets

Assets that lose value ahead of schedule because of the low-carbon transition, such as fossil fuel reserves that cannot be burned under climate policy or demand shifts.

Related: Transition risk, Carbon price, Transition plan
Climate scenario analysis

A method of exploring how physical and transition risks could affect a portfolio or firm under plausible future pathways, such as orderly, disorderly, and hot-house worlds. Outputs are conditional, not forecasts.

Related: Physical risk, Transition risk, NGFS scenarios
NGFS scenarios

Reference climate scenarios published by the Network for Greening the Financial System, spanning orderly, disorderly, and hot-house pathways. Widely used by banks, insurers, and supervisors for risk assessment.

Related: Climate scenario analysis, Carbon price
Carbon price

The cost per tonne of carbon dioxide equivalent imposed by a tax or emissions trading system, or the shadow price a firm uses internally to evaluate investments and risk.

Related: Emissions trading system, Stranded assets, Internal carbon price
Emissions trading system

A cap-and-trade market in which a limit on total emissions is set and allowances are traded, creating a carbon price. Examples include the EU ETS and California's programme.

Related: Carbon price, Carbon border adjustment mechanism
Carbon border adjustment mechanism

A levy on carbon-intensive imports designed to prevent carbon leakage and level the playing field between domestic producers facing carbon costs and foreign competitors that do not.

Related: Carbon price, Emissions trading system
Internal carbon price

A shadow price a company applies in capital budgeting or strategy to reflect future carbon costs, encouraging low-carbon investment decisions before regulation or markets fully price emissions.

Related: Carbon price, Transition plan
Just transition

The principle that decarbonisation should be fair to workers and communities dependent on high-carbon industries, addressing employment, regional economic impacts, and social equity.

Related: Transition plan, Social risk
Greenwashing

Misrepresenting or overstating the environmental credentials of a product, fund, or company, for example through misleading labels, vague claims, or selective disclosure of favourable data.

Related: SFDR, EU Taxonomy, Stewardship
SFDR

The EU Sustainable Finance Disclosure Regulation, which requires financial market participants to classify products as Article 6, 8, or 9 and disclose sustainability risks, adverse impacts, and related policies.

Related: EU Taxonomy, Greenwashing, Principal adverse impacts
EU Taxonomy

A classification system defining which economic activities qualify as environmentally sustainable, based on substantial contribution and do-no-significant-harm criteria. Used for reporting and green fund labelling.

Related: SFDR, Greenwashing
Principal adverse impacts

Mandatory indicators under SFDR showing how investment decisions negatively affect sustainability factors, covering emissions, biodiversity, water, waste, and social and governance matters.

Related: SFDR, Financed emissions
TCFD recommendations

A framework for disclosing climate-related financial risks across four pillars: governance, strategy, risk management, and metrics and targets. Now widely embedded in regulation and standards.

Related: Climate scenario analysis, Transition plan, ISSB
ISSB

The International Sustainability Standards Board, which issued IFRS S1 and S2, global baseline standards for sustainability and climate-related disclosure, including Scope 1, 2, and 3 emissions requirements.

Related: TCFD recommendations, Scope 3 emissions
Adaptation

Adjustments to physical assets, operations, and planning to reduce harm from climate hazards, such as flood defences, cooling systems, or supply chain diversification. Complements mitigation.

Related: Physical risk, Mitigation
Mitigation

Actions that reduce greenhouse gas emissions or enhance sinks, such as efficiency improvements, renewable energy deployment, and avoided deforestation. Distinct from adaptation to impacts.

Related: Adaptation, Carbon offset
Carbon offset

A credit representing one tonne of emissions avoided or removed, purchased to compensate for emissions elsewhere. Quality varies widely, and offsets do not substitute for reducing a company's own emissions.

Related: Mitigation, Greenwashing
Green bond

A fixed income instrument whose proceeds fund eligible environmental projects, governed by voluntary principles such as ICMA's Green Bond Principles. Allocation and impact reporting are key to credibility.

Related: Sustainability-linked bond, Greenium
Sustainability-linked bond

A bond whose interest terms adjust if the issuer meets or misses defined sustainability performance targets, such as emissions reductions, rather than ring-fencing proceeds for specific projects.

Related: Green bond, Greenium
Greenium

The pricing premium, reflected as a lower yield, that green bonds sometimes command versus comparable conventional bonds, reflecting investor demand or perceived risk benefits.

Related: Green bond, Sustainability-linked bond
Climate value at risk

An estimate of the potential financial loss to a portfolio from climate-related risks over a given horizon and confidence level, combining transition and physical exposures under scenario assumptions.

Related: Climate scenario analysis, Physical risk, Transition risk
Stranded asset exposure

The share of a portfolio's value tied to assets that could lose value under transition scenarios, such as fossil fuel reserves, high-carbon infrastructure, or carbon-intensive real estate.

Related: Stranded assets, Climate value at risk
Stewardship

The responsible use of investor influence over investee companies, through voting, engagement, and escalation, to protect and enhance long-term value, including on climate strategy.

Related: Engagement, Proxy voting
Engagement

Direct dialogue between investors and companies or policymakers to encourage improved climate disclosure, strategy, and performance. Effectiveness depends on escalation and clear objectives.

Related: Stewardship, Proxy voting, Just transition
Proxy voting

The exercise of voting rights on shareholder resolutions and management proposals, including climate-related items such as transition plans and lobbying disclosure. A core stewardship tool.
