With growing scrutiny from travellers and investors who demand clarity of sustainability information, and policymakers who mandate increased accountability, there is a shift in the air. Major hotel brands as well as independent owners and operators are increasingly adopting third-party certifications to demonstrate their commitment to sustainability and track performance. There are various types of certifications available to hotels depending on the focus and audience to be reached. This viewpoint concerns the guest-facing certification schemes.

The path to becoming a certified property involves a series of meticulous steps [1]. It begins with selecting a reputable certification body, followed by registration and a thorough self-assessment based on a criteria checklist. However, the heart of this process lies in the on-site audits. Audit tasks in the hotel sustainability certification world extend much beyond simple checklist ticking; auditors must navigate through extensive criteria to effectively evaluate a property's adherence to sustainability standards. These audits are decisive as they assess whether a hotel meets specific standards, such as verifying monthly energy usage records to assessing local biodiversity protection efforts or ensuring that the hotel refrains from contracting suppliers using child labour (see further examples in [2],[3]).

Auditors operate within the complex interplay of evolving standards and the multifaceted operations of hotels. They must engage with various professionals within the hotel, from engineers to chefs and from department managers to front-line staff. The effectiveness and credibility of these audits are paramount to a robust certification.

The forthcoming EU Green Claims Directive addresses these challenges by discussing significant variations among environmental labels concerning transparency, standard comprehensiveness, revision frequency, and the rigor of auditing or verification processes [4]. Although the Directive primarily targets environmental certification, the sustainability certification for hotels also encompasses a wide range of social sustainability criteria, requiring auditors to have expertise in these areas as well.

The expertise, training and in-depth industry knowledge of auditors are crucial. These attributes are foundational in designing a role that guarantees neutrality and results in effective oversight.

With this in mind, the aim of this viewpoint is to explore the strengthening of sustainability auditing processes within the hospitality industry, with the following questions:

  • With more hotels pursuing certification, could the auditing process become a bottleneck due to a shortage of trained auditors?
  • Are the current training programs adequate for auditors to fulfil their responsibilities effectively?
  • From a hotelier's perspective, what experiences have you had with the auditing process?
  • How can technology be incorporated into audit procedures to enhance consistency and impartiality?

Auditing hotels requires specialized knowledge of hotel operations and strong interpersonal skills to assess compliance across various departments. Technical expertise in areas like HVAC and water managment is critical. Currently, there is no formal academic training for auditors, highlighting the need for structured support to enhance their qualifications and ensure certification credibility.
