Frequently Asked Questions (FAQs)

What is interim sustainability management?

A temporary engagement of external sustainability experts who take on responsibility—both operational and strategic—until an internal successor is in place or project goals are achieved.

How long do assignments typically last?

Depending on the assignment, between 3 and 12 months—with the option of a flexible extension.

Is this different from traditional consulting?

Yes – Interim managers take on operational responsibilities and integrate themselves into your organization, rather than simply offering recommendations.

Frequently Asked Questions About
: Interim Sustainability Management & Sustainability Outsourcing

When do companies need to start purchasing CBAM certificates?

The transition period, during which only reporting is required, will remain in effect until the end of 2025. Starting January 1, 2026, importers will be required to purchase and submit CBAM certificates. However, the Omnibus Package proposes a reduced certificate requirement during the initial phase, which could ease the burden on companies—though this has not yet been finalized.

What role does the Corporate Carbon Footprint (CCF) play in CSRD reporting in accordance with ESRS E1?

Under European sustainability reporting standards (ESRS E1: Climate Change), companies are required to report their greenhouse gas emissions transparently. This includes, in particular, the disclosure of Scope 1, Scope 2, and—where relevant—Scope 3 emissions. A structured carbon footprint assessment therefore forms the basis for ESRS-compliant climate reporting.

ESRS E1 (Climate Change) of the CSRD (Corporate Sustainability Reporting Directive) requires companies to quantify their direct and indirect greenhouse gas emissions and disclose reduction targets. The CCF serves as a basis for presenting emissions transparently and fulfilling regulatory requirements.

Can companies offset avoided emissions in their carbon footprint?

Avoided emissions are not part of a company's official carbon footprint in accordance with the GHG Protocol, but are supplementary information. However, companies can use them to present their positive climate impact, for example in sustainability reports or investor relations. For credible communication, it is important to clearly differentiate Scope 4 from your own Scope 1-3 emissions.

Is there an official definition or standard for Scope 4 emissions?

The Greenhouse Gas (GHG) Protocol does not explicitly define Scope 4, but recommends that avoided emissions be disclosed as additional information. International frameworks such as ISO 14067 (Carbon Footprint of Products) and the GHG Protocol for Project Accounting provide methods for calculation. However, there is currently no mandatory standardized reporting for Scope 4.

Why is the Product Carbon Footprint (PCF) relevant for the Carbon Border Adjustment Mechanism (CBAM)?

CBAM, the EU's CO₂ border tax, requires importers to provide evidence of the emissions-based carbon footprint of products. A PCF helps to verifiably document emissions and minimize potential customs costs due to CO₂ emissions.
