Moreover, certificates and labels like the Green Key, awarded to tourism enterprises that assert for instance that they use of organic food/ beverages and green household products (e.g. detergents), must rely on the respondent's honesty. It is always, therefore, a point to consider whether the people in charge are in fact replying truthfully. Lastly, it is possible that small and medium-sized enterprises may not be able to cope with the costs incurred by becoming more eco-friendly, despite governmental subsidies, which could mean that it is the large enterprises who reap the above-mentioned benefits while the smaller ones struggle to survive. Environmentally conscious transport companies may profit from mitigation, and in more general terms the providers of eco-labelled services may expect a growth in demand.
