Resumo(s)
Com o aumento da concorrência e pressão para uma maior sustentabilidade ambiental é cada vez mais importante recorrer a práticas internas de forma a obter reconhecimento no mercado e uma performance mais sustentável. O presente estudo pretende analisar a relação entre as práticas internas de sustentabilidade e a performance sustentável, medida de acordo com as três dimensões do modelo de Triple bottom line (TBL), a performance ambiental, económica e social. Adicionalmente, o estudo avalia como é que a certificação pela norma ISO 14001 afeta estas relações. As práticas internas analisadas foram as compras ecológicas, o design ecológico e a produção sustentável.
De forma a testar o modelo conceptual proposto foi desenvolvido e aplicado um questionário online, enviado por email para as empresas de manufatura em Portugal. Foram consideradas 222 respostas de empresas com 50 ou mais colaboradores, das quais 75 respostas foram obtidas de empresas certificadas e 147 respostas de empresas não certificadas pela ISO 14001.
Os resultados deste estudo demostraram que a gestão ambiental interna tem uma relação positiva e significativa com as práticas internas de sustentabilidade. Das três práticas internas de sustentabilidade consideradas as compras ecológicas e a produção sustentável mostraram uma relação positiva e significativa com a performance sustentável. No entanto, o efeito do design ecológico na performance sustentável não é significativo. Relativamente à certificação pela ISO 14001, é percetível que apenas existe influência da certificação na relação entre a gestão ambiental interna e as compras ecológicas. Para as restantes relações não foram identificadas diferenças significativas.
With increasing competition and pressure for greater environmental sustainability, it is increasingly important to use internal practices in order to gain market recognition and a more sustainable performance. This study intends to analyze the relationship between the internal practices of sustainability and the sustainable performance measured, according to the three dimensions of the Triple bottom line (TBL) model, environmental, economic and social performance. Additionally, the present study assesses how ISO 14001 certification affects these relationships. The internal practices analyzed in this study were ecological purchases, ecological design and sustainable production. In order to test the proposed conceptual model, an online questionnaire was developed and applied, then to the manufacturing companies in Portugal. In total 222 responses were considered from companies with 50 or more employees, of which 75 answers were from certified companies and 147 responses from companies not certified by ISO 14001. The results of this study demonstrated that internal environmental management has a positive and significant relationship with internal sustainability practices. Of the three internal sustainability practices considered, the green purchases and sustainable production showed a positive and significant relationship with sustainable performance. However, the effect of eco-design in sustainable performance it is not significant. Regarding the certification by ISO 14001, it is noticeable that there is only an influence of the certification on the relationship between internal environmental management and green purchases. For all other relationships there is no significant differences.
