What Are Carbon Offsets in ESG Reporting?

Carbon offsets are a crucial tool for businesses striving to meet environmental goals, but using them responsibly requires clear, standardized reporting. As companies aim for net zero, carbon neutrality, and better climate accountability, the question arises:

How do you include carbon offsets in ESG reporting?

This guide explains how businesses can transparently report the use of carbon offsets under major frameworks like GRI, TCFD, CDP, and CSRD, and what best practices ensure offsets support, not weaken, your ESG strategy.

Why Carbon Offsets Matter in ESG Reports?

For many organizations, achieving near-term emissions targets without offsets is difficult. Carbon offsets allow companies to:

Compensate for residual emissions
Support climate solutions beyond their value chain
Show commitment to broader global sustainability goals
Enhance ESG performance scores and appeal to conscious investors

But their inclusion in ESG reports must be handled with integrity and detail. Over-relying on offsets or reporting them vaguely risks greenwashing claims and regulatory scrutiny.

Key ESG Frameworks and How They View Carbon Offsets

1. Global Reporting Initiative (GRI)

GRI 305: Emissions is the standard most relevant to carbon accounting.

How to report offsets under GRI:

Disclose gross emissions separately from offsets
Report the total tCO₂e offset, type of projects, and verification standards used
Explain whether offsets are used to claim carbon neutrality or net zero
Clarify if offsets are internally generated or purchased from third parties

Best practice: Use GRI to distinguish between reduction efforts (e.g., energy efficiency) and compensation measures (offsets).

2. Task Force on Climate-related Financial Disclosures (TCFD)

TCFD focuses on climate-related risks and opportunities that could impact financial performance.

Offsets fit into TCFD in several areas:

Metrics and Targets: Offsets can support net-zero targets, but firms must report them separately from actual emissions reductions
Strategy: Disclose reliance on offsets in your long-term decarbonization plan
Risk Management: Address the risk of offset underperformance or regulation changes
Governance: Explain who approves offset use and how decisions are reviewed

Best practice: Be transparent about your offsetting strategy's limits and future plans to phase out offsets as technology or regulations evolve.

3. CDP (Carbon Disclosure Project)

CDP questionnaires now specifically ask for offset use and quality.

Key points:

Report whether offsets are used for Scope 1, 2, or 3 emissions
Describe the type of offset projects, geography, certification, and retirement dates
Explain how offsets fit into your transition plan

Best practice: Prioritize removal-based offsets over avoidance credits where possible, as CDP and many investors now view them as more credible.

4. Corporate Sustainability Reporting Directive (CSRD – EU)

CSRD, through the European Sustainability Reporting Standards (ESRS), sets stricter expectations for emissions transparency.

For offsets:

Companies must disclose gross emissions separately from net values
Use of carbon credits must be clearly detailed, including type, volume, origin, and certification
Firms must explain whether credits are used within or beyond the organization’s value chain

Best practice: Use carbon offsets to complement deep emission cuts, not replace them. CSRD emphasizes real reductions.

Best Practices for Including Carbon Offsets in ESG Reporting

Always report gross and net emissions separately
- Show your actual impact before offsets
- Avoid misleading net-zero claims if reductions are minimal
Disclose details about the offsets
- Type (removal vs avoidance)
- Project location and category
- Verification standard (e.g., Verra, Gold Standard)
- Retirement information
Align offsets with your business strategy
- If you're a manufacturer, support projects in your supply chain
- If you're service-based, consider nature-based or tech-based removals
Use only third-party verified carbon credits
- Unverified credits or future promises can damage trust
- Refer to recognized standards like VCS, Gold Standard, ACR
Avoid overreliance on offsets
- Make clear that emissions reduction is your priority
- Use offsets only for residual or hard-to-abate emissions
Communicate with credibility
- Avoid marketing terms like “100% green” without proof
- Provide links to registries or verification documents when possible

Common Reporting Mistakes to Avoid

Reporting only net emissions, without showing what was offset
Using unverified or outdated credits
Claiming carbon neutrality for the entire business when only a product line is covered
Hiding offsets in general sustainability language
Assuming all ESG raters value offsets the same, they don’t

Final Thoughts

Carbon offsets can play a legitimate and valuable role in your ESG strategy, but only if they are used transparently, reported separately, and supported by real efforts to cut emissions at the source.

By integrating offsets responsibly into reporting frameworks like GRI, TCFD, CDP, and CSRD, businesses show accountability and leadership in climate action.

Offsetting should never be your whole climate strategy. But when it is measured, verified, and disclosed well, it can be an important piece of your path to net zero.
