4C in numbers

As of 31 December 2022, 191 producing groups were 4C certified encompassing more than 307,000 coffee producers in 17 countries around the world.

Over 94% of 4C coffee producers are smallholders, meaning producers whose workforce consists primarily of family and whose coffee farm is normally not larger than 5 ha (see 4C Glossary for the full definition). Total green coffee production amounted to 28.3 million bags (60 kg) on nearly 832 thousand ha of the farm area. In 2022, reported purchases of 4C certified coffee reached their historical height. We are very pleased to see the growth in demand for sustainable coffee, as well as the trust in the credibility and reliability of the 4C standard, and anticipate this trend to continue.

Trainings and events

With the purpose of capacity building of 4C System users and informing them about any changes to the 4C System, 4C regularly offers 4C trainings.

In 2020, 4C offered several introductory seminars, reflecting the main changes in the 4C System, in particular connected to the revision of the critical system documents in July 2020. 4C further developed and conducted online modular three-day trainings, available in English, Spanish, Portuguese and Vietnamese languages. In total, 123 participants joined these trainings which entailed a crucial update on the latest revision of the 4C Code of Conduct and guided the participants through the certification process, ensuring better understanding and implementation of the new audit requirements and procedures. The trainings also covered an increasingly important chain of custody certification. 4C trainings are an important prerequisite for auditors before they may conduct a 4C audit.

In addition to the technical trainings, we also organized a series of bi-weekly virtual seminars to support the dialogue and bring together the coffee and sustainability communities, despite the difficult situation, caused by the COVID 19 outbreak. Nearly 400 people participated and provided their positive feedback, looking forward to the continuation of the series in 2021.

4C audits

During 2020, Certification Bodies cooperating with 4C conducted 110 audits for 4C Units to certify compliance with the 4C Code of Conduct, whereas the remaining 4C Units have been evaluated based on their Annual Updates.

57 individual auditors were involved in the team of auditors checking and recording the compliance of coffee producers and service providers or evaluating reports fulfilling the four-eyes-principle of certification. Around two-thirds of the audits were initial (29) or recertifications (36), meaning the complete audit checklist is applied and a new 4C certificate is issued as a result. The remaining 45 audits had a limited scope and confirmed the validity of a previously issued certificate.

Types of certification under 4C

Certification audit

  • Certification audits are the basis to issue a 4C certificate. Certification audits must be conducted during harvest season and need to take place on-site at least every three years.
  • The first audit of a coffee producer group entering the 4C System is called the “initial” audit. A positive decision results in a 4C certificate with a validity of three years and includes the requirement of two annual updates in form of a desk-audit.
  • Subsequent audits with increased requirements are called “recertification” audits. Again, a positive decision results in a 4C certificate with a validity of three more years and includes the requirement of two annual updates in form of a desk-audit.


  • Surveillance audits can be required by the CB or 4C to verify compliance with the 4C requirements during the validity period of a certificate issued by the respective CB. Surveillance audits may focus only on the implementation of specific aspects of 4C requirements and can be either on-site or desk-audit, depending on the means required to fully check compliance with the relevant 4C requirements.


  • In case the management of a producer group wants to include more producers or processors in a 4C Unit, an addendum audit can be conducted which has a limited scope in terms of sampling only the newly included business partners of a 4C Unit. The original validity period of the respective certificate remains the same.


  • 4C may initiate additional audits planned randomly or on a risk basis after risk evaluations to fulfilling its oversight role and maintain the integrity of the 4C System. These audits are conducted by 4C auditors and are used to verify compliance of the 4C System users with the 4C Code of Conduct and/or confirm correct auditing practices by certification bodies and auditors.

Breaking down the total amount of audits by country, including surveillance audits and addendum audits, the vast majority was conducted in Vietnam (53), followed by Indonesia (16), Brazil (8),  Mexico (7) and Ivory Coast (5).

4C continues to be a robust certification system, proven by the increasing interest of roasters to source sustainable coffee and choosing 4C. With 4C certified producer groups they can count on reliable partners to achieve their goals. A vital part of the system is the inclusive approach, which enables coffee producers to enter certification while actively encouraging the implementation of better and more sustainable agricultural practices. This ensures the long-term viability of growing coffee.

We always pursue to further strengthen the credibility of the 4C System by listening to feedback by system users and stakeholders. If you would like to leave your feedback or report a violation of the 4C System, please use our stakeholder feedback form.
