A

Article 8 Fund

Regulation

Under the EU's SFDR, an Article 8 fund 'promotes' environmental or social characteristics alongside financial objectives. Also called 'light green' funds. Companies in the portfolio do not need to have sustainability as their core objective, but the fund must disclose how ESG characteristics are considered.

Article 9 Fund

Regulation

Under the EU's SFDR, an Article 9 fund has sustainable investment as its core objective. Also called 'dark green' funds. These funds must demonstrate that all investments contribute to an environmental or social objective and do no significant harm (DNSH) to other objectives.

C

Carbon Neutral

Environmental

A state where net carbon emissions are zero, typically achieved by reducing emissions and offsetting remaining emissions through carbon credits or removal projects. Not to be confused with 'net zero' which typically requires deeper emission reductions.

CDP (formerly Carbon Disclosure Project)

Framework

A global disclosure system for companies to report environmental information to investors. CDP covers climate change, water security, and forests.

Controversy

Core

A negative event or allegation related to a company's ESG practices, such as environmental violations, labor disputes, governance failures, or product safety issues. In Walk-The-Talk Score, controversies can significantly reduce credibility scores.

CSRD (Corporate Sustainability Reporting Directive)

Regulation

EU regulation requiring large companies to report detailed sustainability information. CSRD significantly expands ESG disclosure requirements and introduces mandatory third-party assurance.

D

Double Materiality

Core

An approach to ESG assessment that considers both how sustainability issues affect the company (financial materiality) and how the company affects society and the environment (impact materiality).

E

Engagement

Investing

Active dialogue between investors and companies to influence corporate behavior on ESG issues. Can include private discussions, shareholder resolutions, and proxy voting.

ESG (Environmental, Social, Governance)

Core

A framework for evaluating corporate behavior beyond financial performance. Environmental factors include climate impact and resource use. Social factors include labor practices, diversity, and community impact. Governance factors include board structure, executive compensation, and shareholder rights.

ESG Integration

Investing

The systematic inclusion of ESG factors in investment analysis and decision-making to better manage risks and identify opportunities. Distinct from exclusionary screening or impact investing.

EU Taxonomy

Regulation

A classification system establishing which economic activities qualify as environmentally sustainable. Used to direct capital toward activities that contribute to climate and environmental objectives.

G

Greenwashing

Core

The practice of making misleading or unsubstantiated claims about the environmental benefits of a product, service, or company. Greenwashing can be intentional deception or the result of poor measurement and verification.

GRI (Global Reporting Initiative)

Framework

An international organization providing the most widely used sustainability reporting standards. GRI standards cover economic, environmental, and social impacts.

I

Impact Investing

Investing

Investments made with the intention of generating measurable positive social and environmental impact alongside financial returns.

ISSB S1 (General Sustainability Disclosures)

Framework

The first of two inaugural standards from the IFRS Foundation's International Sustainability Standards Board (ISSB). S1 requires companies to disclose material sustainability-related risks and opportunities across their entire value chain, covering governance, strategy, risk management, and metrics.

ISSB S2 (Climate-related Disclosures)

Framework

The second ISSB standard, focused specifically on climate-related risks and opportunities. S2 builds on TCFD recommendations and requires disclosure of Scope 1, 2, and 3 greenhouse gas emissions, climate scenario analysis, and transition planning. Effective for annual reporting periods from January 2024.

J

Just Transition

Social

The principle that the shift to a sustainable economy should be fair and inclusive, ensuring workers and communities dependent on carbon-intensive industries are supported through the transition.

M

Materiality

Core

The concept that ESG factors are relevant if they could influence investor decisions or significantly impact stakeholders. Double materiality considers both financial impact on the company and the company's impact on society and environment.

N

Negative Screening

Investing

An investment approach that excludes companies or sectors based on specific ESG criteria, such as tobacco, weapons, or fossil fuels.

Net Zero

Environmental

A commitment to reduce greenhouse gas emissions to as close to zero as possible, with any remaining emissions balanced by carbon removal. More ambitious than carbon neutral, net zero typically requires 90%+ emission reductions before offsets.

P

PAI (Principal Adverse Impacts)

Regulation

Under the EU's SFDR, Principal Adverse Impacts are the negative effects that investment decisions have on sustainability factors - including climate, environment, social and employee matters, human rights, and anti-corruption. Financial market participants must report on 18 mandatory PAI indicators annually.

Physical Risk

Environmental

Financial risks arising from the physical impacts of climate change, including acute risks (extreme weather events) and chronic risks (sea level rise, temperature increases).

Proxy Voting

Scope 1 Emissions

Environmental

Direct greenhouse gas emissions from sources owned or controlled by a company, such as company vehicles, on-site fuel combustion, and manufacturing processes.

Scope 2 Emissions

Environmental

Indirect greenhouse gas emissions from purchased electricity, steam, heating, and cooling consumed by a company. These are emissions the company causes indirectly through energy consumption.

Scope 3 Emissions

Environmental

SFDR (Sustainable Finance Disclosure Regulation)

Regulation

EU regulation requiring financial market participants to disclose how they integrate sustainability risks and consider adverse sustainability impacts in their investment decisions.

Stranded Assets

Environmental

Assets that suffer from unanticipated or premature write-downs due to factors such as climate policy, technology shifts, or changing market demand. Commonly applied to fossil fuel reserves that may become uneconomic.

T

TCFD (Task Force on Climate-related Financial Disclosures)

A proprietary ESG credibility metric that measures whether companies deliver on their sustainability commitments. Unlike disclosure-based scores, Walk-The-Talk Score compares stated commitments to verified evidence of action.
