Glossary

Clear definitions of the sustainability, climate, and ESG terms that matter most — from CBAM and CSRD to SBTi and PCAF. Written by Semtrio's advisory team.

Are there any terms you don't recognise?

Browse A-Z

N

Net Zero

Net zero refers to a state in which an organization's greenhouse gas emissions are reduced as far as possible along a science-consistent 1.5°C pathway, with any remaining residual emissions balanced by an equivalent volume of permanent, verified carbon removal — such that the organization makes no net addition of greenhouse gases to the atmosphere.

Climate Strategy

Non-Financial Reporting Directive (NFRD)

The Non-Financial Reporting Directive was the European Union's first mandatory sustainability disclosure law, applying from the 2018 financial year until it was superseded by the Corporate Sustainability Reporting Directive.

ESG Reporting

O

Organizational Boundary

An organizational boundary defines which entities' emissions an organisation includes in its greenhouse gas inventory, set using either the equity share approach or one of two control approaches.

Carbon Accounting

P

Partnership for Carbon Accounting Financials (PCAF)

PCAF (Partnership for Carbon Accounting Financials) is a global industry-led initiative that provides a standardized methodology for financial institutions to measure and disclose the greenhouse gas emissions associated with their loans and investments — enabling banks, asset managers, and insurers to quantify their financed emissions as Scope 3 Category 15 and set credible decarbonization targets.

Sustainable Finance

Physical Risk

Physical risk is the financial risk to an organisation from the physical effects of climate change — divided between acute risks arising from extreme weather events and chronic risks arising from long-term shifts in climate patterns.

Regulation & Compliance

Portfolio Decarbonization

Portfolio decarbonisation is the process by which a financial institution reduces the greenhouse gas emissions associated with its lending and investment portfolio, rather than only those from its own operations.

Sustainable Finance

Product Carbon Footprint (PCF)

A product carbon footprint is the total greenhouse gas emissions associated with a specific product across a defined portion of its life cycle, expressed as CO₂ equivalent per functional unit.

Carbon Accounting

S

Science Based Targets initiative (SBTi)

The Science Based Targets initiative (SBTi) is an independent body that validates corporate greenhouse gas reduction targets as consistent with the level of decarbonization required to limit global warming to 1.5°C — providing criteria, tools, and public validation for near-term emissions reduction targets and long-term net zero commitments.
