Sustainability Terms, G Edition: Introduction
Sustainability Terms, G Edition continues our monthly A-Z guide with eight connected terms that businesses are increasingly seeing in reports, tenders, carbon plans and marketing. This month moves from the gases a company measures to the standards used for reporting, then into claims, finance and carbon removals.
The aim is simple: make the language useful enough to support better decisions. Each term has a practical business role, so knowing what it means can help teams ask better questions, spot weak claims and keep sustainability work commercially grounded.
Greenhouse Gas (GHG)
A greenhouse gas traps heat in the atmosphere and contributes to climate change.
Carbon dioxide is the best-known example, alongside methane, nitrous oxide and several industrial gases.
Business inventories usually convert these gases into carbon dioxide equivalent, or CO2e, so different emissions can be compared in one measure.
Sustainability Terms, G Edition starts here since every credible footprint needs a clear view of what is being counted.
GHG Protocol
The GHG Protocol supplies the most widely used greenhouse gas accounting standards for companies.
Its corporate framework covers Scope 1, Scope 2 and Scope 3 emissions, giving businesses a common method for measuring and reporting a footprint.
In July 2026, GHG Protocol announced work on a consolidated corporate standard with ISO 14064-1.
That makes this term especially relevant for companies building carbon data that needs to stand up to scrutiny.
Global Warming Potential (GWP)
Global Warming Potential compares the warming effect of a greenhouse gas with carbon dioxide across a chosen time period.
The figure helps convert gases such as methane or refrigerants into CO2e.
This matters for sectors where carbon dioxide is not the main issue.
A facilities team dealing with refrigerants, or a food business tracking methane, needs GWP to compare impacts consistently and focus action on the largest sources.
Global Reporting Initiative (GRI)
The Global Reporting Initiative produces widely used standards for public reporting on economic, environmental and social impacts.
GRI reporting gives companies a structured way to explain what they affect, how they manage those impacts and what progress looks like.
Its revised Biodiversity Standard, GRI 101, became effective for reporting in January 2026.
Sustainability Terms, G Edition includes GRI since clearer reporting can support trust with customers, investors and supply-chain partners.
Get In TouchGreen Claims
Green claims are environmental statements about a product, service, process, brand or business.
In the UK, the Competition and Markets Authority’s Green Claims Code sets six checks for claims, covering truthfulness, clarity, evidence and the full life cycle where relevant.
Good claims are precise and provable.
This gives marketing teams a useful test before publishing words such as green, sustainable, lower-carbon or environmentally friendly.
Greenwashing
Greenwashing happens when environmental communication creates a misleading picture of impact or performance.
The risk can come from vague wording, missing evidence, selective information or imagery that suggests more than the facts support.
ASA and CAP guidance requires the basis of environmental advertising claims to be clear.
Businesses that connect marketing with real data protect trust, reduce regulatory exposure and give sales teams stronger proof to use with customers.
Green Finance
Green finance directs capital into activities linked to climate and environmental outcomes.
It can include loans, bonds, investment funds and public finance linked to clean energy, lower-carbon infrastructure or nature.
The UK Government’s 2025 Green Financing Framework includes climate action, natural ecosystem restoration and green-sector jobs.
For companies seeking funding, clear sustainability data can make projects easier to assess and can strengthen the commercial case behind investment.
Greenhouse Gas Removals (GGR)
Greenhouse Gas Removals actively take greenhouse gases, mainly carbon dioxide, from the atmosphere and store them.
Approaches include nature-based methods and engineered options such as direct air capture with storage.
The UK Government published its response to the independent GGR review in July 2026.
Reduction still comes first, with removals linked to residual emissions that are harder to eliminate.
Buyers should ask what is removed, how it is measured and how storage is protected.
Sustainability Terms, G Edition: Wrap-Up
Sustainability Terms, G Edition links measurement, reporting, communication, finance and climate action in one article.
Greenhouse gases need consistent accounting, comparable climate impact and credible reporting; then any public claims need evidence behind them.
Finance can support the work, and removals sit later in a credible climate plan rather than replacing reductions.
For SMEs, the practical gain is clearer decision-making across finance, operations, procurement, marketing and leadership, with less room for misunderstood terms to hide weak action.
