Santiago, Chile- The OLORES25 Congress, held in Santiago, Chile, brought together leading professionals, researchers, and industry representatives from around the world to address the growing challenges of odour management. Organized by the AMIGO Association with the support of Olores.org and other collaborators, this event has become a key meeting point for sharing experiences, technological advances, and regulatory perspectives in the field of environmental odours.

   One of the highlights of the congress was the presentation of the E&T&C certification (Engagement, Transparency & Communication), a pioneering initiative designed to raise professional standards and foster a culture of excellence in odour management. Unlike traditional certifications focused solely on technical knowledge, E&T&C emphasizes the importance of community engagement, transparent data management, and effective communication with all stakeholders involved in odour issues.

   Many attendees expressed their enthusiasm about how E&T&C can help improve odour management practices, especially in urban areas with high population density, where technological solutions must be complemented by active dialogue with communities. Several academic institutions also showed interest in integrating E&T&C principles into their curricula, recognizing the value of a holistic approach that combines technical expertise with social responsibility.

   The introduction of the E&T&C certification at OLORES25 marks a significant step forward for the sector. By building bridges between international experience and local realities, this initiative paves the way for a new era of sustainable, transparent, and inclusive odour management.

   The first training sessions for the accreditation of auditors in the E&T&C (Engagement, Transparency & Communication) certification have concluded successfully, marking a milestone in the professionalization of environmental management and the relationship between industry and society.

A new standard in commitment and transparency

   The E&T&C certification, promoted by the consultancy Ambiente et Odora S.L. and the portal olores.org, was created in response to the growing need to evaluate and recognize organizations’ commitment to transparency and communication with their environment, especially in the field of odor management and environmental impact. This new standard focuses on three fundamental pillars: the real commitment of companies, transparency in their processes, and the quality of communication with the community.

Auditor training: a commitment to excellence

   During the sessions, participants from all over the world received specialized training on the requirements, methodologies, and best practices necessary to audit under the E&T&C scheme. The program was delivered in an online theoretical session that enabled future auditors to acquire the necessary competencies to evaluate the performance of organizations in the three critical domains of the certification.

   The training, which was free of charge in its first edition, included the participation of professionals from different sectors interested in expanding their profiles and accessing new business opportunities. Upon completion of the process, attendees obtained official accreditation as E&T&C auditors, enabling them to offer this service to companies seeking to differentiate themselves and improve their relationship with society.

Impact and opportunities

   The role of the E&T&C auditor is emerging as key to driving continuous improvement in environmental management and strengthening trust between industry and citizens. In addition, the certification opens new avenues for collaboration and business for auditors, who will be able to integrate this service into their portfolio and position themselves as leaders in innovative social and environmental responsibility solutions.

Medellin, Colombia- Within the framework of the 1st International Congress on Odour Environmental Management, held from April 3 to 5, 2025 at the Joaquín Antonio Uribe Botanical Garden in Medellín, the E&T&C certification played a leading role as a benchmark for progress in the field of odour management. The event, organized by ACODAL Seccional Noroccidente with the support of Olores.org and the AMIGO Association, brought together experts and key stakeholders from around the world to discuss the challenges and advances in odour management.

   During one of the most anticipated sessions, the E&T&C certification (Engagement, Transparency & Communication) was presented in detail—a novel and unique methodology that responds to the growing demand for pathways to recognize commitment in odour management. Unlike other recognitions, the E&T&C certification not only validates theoretical knowledge but also requires practical experience in active community engagement, transparency in data and process management, and effective communication with all stakeholders. These aspects are fundamental for designing odour management and mitigation strategies that are both acceptable and sustainable in the long term.

   The presentation delved into how the certification process includes the assessment of competencies in areas such as the identification of odour sources, the application of international regulations, the management of citizen complaints, the design of control systems, and the use of analytical and sensory tools for environmental monitoring. This comprehensive approach was especially valued by attendees, who highlighted the usefulness of having an international standard that raises the quality of projects.

   The congress, which included practical workshops, round tables, and a technology exhibition, served as a platform for engineers, consultants, environmental authorities, and industry representatives to explore the advantages of the E&T&C certification as a driver of innovation and a guarantee of best practices. The presentation sparked a lively debate on the need to strengthen ongoing training and international collaboration to address current challenges in odour environmental management.

   The introduction of the E&T&C certification in Colombia marks a milestone for the sector in Latin America, opening new opportunities for professional excellence and sustainable development in odour management.
