As more businesses commit to net zero goals and climate strategies, terms like carbon offsets and carbon credits appear frequently in ESG reports, sustainability roadmaps, and regulatory frameworks. Although they are often used interchangeably, these two terms refer to different concepts within the carbon market.

If you're asking, What is the difference between a carbon offset and a carbon credit? - you're not alone. Let's break it down clearly and practically.

What Are Carbon Credits?

Carbon credits are the units of measurement used to quantify the climate benefit of an emissions reduction or removal project.

One carbon credit = one metric ton of CO₂ (or CO₂ equivalent) reduced or removed from the atmosphere.
These credits are created by verified environmental projects such as reforestation, renewable energy, methane capture, and direct air capture.
Projects must meet standards set by third-party verifiers such as Verra, Gold Standard, or Climate Action Reserve to generate official carbon credits.

Think of carbon credits like currency, they are the certificates proving that a measurable climate benefit has occurred.

What Are Carbon Offsets?

Carbon offsets refer to the action or process of compensating for greenhouse gas emissions by purchasing carbon credits from certified projects.

Offsets are what organizations do with carbon credits.
When a company emits carbon it cannot reduce, it can offset those emissions by purchasing and retiring an equal number of carbon credits.
The retirement of these credits ensures they are not sold again or double counted.

Think of a carbon offset as the transaction, and the carbon credit as the unit being transacted.

A Simple Analogy

Imagine you want to balance your carbon "account."

Carbon credit: The actual unit you can use to reduce your balance.
Carbon offset: The action of applying that unit to erase your emissions.

In short:

You purchase carbon credits to perform a carbon offset.

Why It Matters to Understand the Difference?

Clarity is essential for credible climate strategy. Here’s why distinguishing between offsets and credits is important:

1. For ESG Reporting and Transparency

When reporting progress toward net zero or climate targets, companies must clearly communicate whether they are using offsets and how many credits they have retired.

2. For Compliance vs Voluntary Use

In compliance markets (like the EU Emissions Trading System), carbon credits are regulated allowances.
In voluntary markets, businesses choose to offset emissions using credits from verified projects.

Confusing the two can result in reporting errors, reputational risk, or misalignment with climate standards.

3. For Strategy Development

Carbon credits can also be bought as investment instruments or for future planning. Businesses may hold credits without immediately using them as offsets. Clear separation helps track when and how credits are applied.

Carbon Credits Can Be Used for More Than Offsetting

While carbon credits are commonly retired to offset emissions, they may also be:

Traded: In voluntary or compliance carbon markets
Held in inventory: For future use or price management
Used for branding or certifications: As part of carbon-neutral product claims or corporate initiatives

Not all carbon credits result in an immediate offset, only those that are officially retired in a registry contribute to a company's offset total.

Common Misconceptions

Misconception 1: “Carbon credits and carbon offsets are the same thing”

Not quite. A credit is the unit. An offset is the use of that unit to neutralize emissions.

Misconception 2: “All carbon credits are high quality”

Carbon credits vary in quality. Only third-party verified, additional, and permanent credits should be used for meaningful offsets.

Misconception 3: “Carbon offsetting is the only use for credits”

Credits may also serve other purposes like compliance obligations, supply planning, or as a climate investment tool.

Summary: Key Differences at a Glance

What it is	A verified unit of carbon reduction/removal	The action of compensating for emissions
Purpose	Traded or retired to account for emissions	Used to balance or neutralize emissions
Measured by	One metric ton of CO₂ equivalent	Based on total credits used to offset
Registry Involvement	Tracked and verified in carbon registries	Requires retirement in a public registry
Common Users	Project developers, buyers, investors	Businesses and individuals offsetting emissions

Final Thoughts

Understanding the difference between carbon offsets and carbon credits is more than just terminology, it is essential for credible climate action, transparent reporting, and ESG accountability.

By purchasing high-quality carbon credits and applying them properly as offsets, businesses can play a direct role in funding global decarbonization while meeting their own sustainability goals.
