I dont' really understand what the author is trying to say here. Does he want to say "this deos not include ... "?
This is referring to the financial burden that some EU regulations (and quality ceritifications) have on small businesse sin the tourism industry.

Disponer de esta información, contribuye a visibilizar los perjuicios económicos sufridos como consecuencia de la asunción de estos costes por empresas hoteleras de menor tamaño, lo cual no propicia la implantación de sellos voluntarios de calidad o medioambientales por parte de los establecimientos hoteleros.

My rough draft:
Having this information available will help to shed light on the negative financial effects of smaller hotels assuming these costs, which does not favour the voluntary environmental or quality certifications on the part of the hotel establishments.
