- Determinantes da certificação ambiental nos estabelecimentos hoteleiros em PortugalPublication . Silva, Anita; Martins, Catarina Antónia; Alves, JorgeO presente estudo tem como objetivo analisar os determinantes da certificação ambiental em empresas do setor hoteleiro em Portugal, considerando as características dos hotéis que a empresa explora. A amostra é constituída por empresas hoteleiras com informação disponível na base de dados Sistema de Análise de Balanços Ibéricos (SABI) e com informação disponível sobre os hotéis que exploram no Registo Nacional de Turismo (RNT) no ano de 2021. A amostra final é constituída por 947 empresas, das quais 88 possuem ou exploram hotéis com algum tipo de certificação ambiental e 859 empresas não possuem ou exploram qualquer hotel com certificação ambiental. Para testar as hipóteses de investigação utilizou-se um modelo de regressão Tobit, o qual tem como variável dependente o número médio de hotéis com certificação ambiental que cada empresa explora e como variáveis dependentes a afiliação a uma marca, a classificação hoteleira, a dimensão hoteleira e rendibilidade das vendas. Os resultados indicam que a afiliação a uma marca, a classificação hoteleira e a dimensão hoteleira são fatores que explicam a certificação ambiental, enquanto a rendibilidade das vendas não se mostrou estatisticamente significativa.
- Determinants of environmental certification in Portuguese hotel companiesPublication . Martins, Catarina Antónia; Alves, Jorge; Silva, AnitaThere are many responsible business and investment initiatives in the field of environmental performance, and among these, certification is a targeted mechanism. In this work, we intend to study the determinants of environmental certification of hotel companies, analysing the Portuguese case. The empirical study considers hotel companies established in Portugal that may operate one or more hotel units. The information retrieved from the Portuguese National Tourism Registry and Iberian Balance Sheet Analysis System database was coded, and a database was built in the SAS software. Variable and data analysis was conducted using descriptive statistics, variable correlations, and the Tobit regression model. The results indicate that affiliation to a brand, hotel classification and hotel size are factors that explain environmental certification, but the return on sales was not statistically significant in this study. These results are important to understanding the determinants of environmental certification in hotel companies since, as a topic of research, it has had little attention prior to the study for the Portuguese case, thus reinforcing the importance of this research. The study also reveals the restricted sample of hotel companies with environmental certification in Portugal, which did not allow computing other study variables that would improve the empirical work.
- Determinants of environmental certification of hotel companies. an analysis of the portuguese casePublication . Martins, Catarina Antónia; Alves, Jorge; Silva, AnitaGoal: Sustainability in tourism is one of the major topics of research. Sustainability is also a major issue of interest for all tourism actors in tourism supply and a major concern for tourism demand. From all stakeholders involved in tourism activity, hotel companies are urged to install responsible businesses and investment (Aznar et al., 2016; Claver-Cortés et al., 2007; Geerts, 2014; Park & Kim, 2014;Rodríguez & Cruz, 2007; Singal, 2014). The aim of the present paper is to identify main determinants of environmental certification of hotel companies in Portugal. Method: The present study uses a methodology based on the analysis of hotel companies that have hotel units certified and those not having certified hotels units. Each company is established in Portugal and may operate one or more hotel units. The dataset was created considering two different databases: data from Hotel Establishments, such as hotels, aparthotels and Pousadas nationwide, registered in the Portuguese National Tourism Registry in 2021; data from the Analysis of Iberian Balance Sheets (SABI) database from Bureau van Dijk obtaining the economic and financial data of companies that manage those hotel units. Several variables were selected to assess the determinants of environmental certification related to the characteristics of hotel establishments. Financial indicators were also computed to determine the influence of financial performance on environmental certification. Hypothesis were established concerning hotel companies’ dimension, star rating, affiliation to a brand and financial performance. Data analysis and Tobbit regression were computed to test hypothesis. Findings: The empirical results show that dimension, star rating and affiliation explain environmental certification. In fact, hotel companies with a higher average capacity also have a higher average of certified hotels. Likewise, hotel companies with a higher average on stars rating also have a higher average of certified hotels. Still, hotel companies with a higher average of affiliated hotels also have a higher average of certified hotels. Hotels with higher star rating are more concerned with environmental certification what could be explained by the type of more demanding consumer. Also, brand affiliated hotel companies adopt more frequently environmental certification since management processes are standardized and hotel chains may support individual units adopting certification (Gil et al., 2001). Hotel companies with higher capacity are more concerned with cost savings achieved through environmental certification and since larger hotels have a reater impact on the environment they are exposed to considerable environmental pressures from stakeholders (Gil et al., 2001). Concerning financial indicators it was not possible to obtain statistically significant results. Though, for financial indicators as return on sales and return on equity, we could obtain positive results concerning a positive relation between financial performance and environmental certification. These results are in line with other works studying other countries as is the case of Gil et al. (2001), Duric and Topler 55 (2021), Cavero-Rubio and Amorós-Martínez (2020), Molina-Azorín et al. (2009) and Segarra-Ona et al. (2012). Limitations: Limitations of the study are related to the reduced number of hotel companies in Portugal that have environmental certified hotel units. Practical implications: The results of this study are important for hotel managers specially those managing higher star rating hotels and those managing higher dimension hotels. Future research could address hotel establishments instead of hotel companies and consider other types of indicators that relate to sustainability practices. Originality: This paper intends to fill a gap in literature studying the Portuguese case on the subject of the determinants of environmental certification and how it relates to financial performance of hotel companies.
