The Biosphere certificate is an international recognition that certifies a company or destination complies with sustainability criteria aligned with the United Nations Sustainable Development Goals (SDGs). This certificate ensures that the accommodation adopts environmental, economic, and social responsible practices.
In a market increasingly oriented towards ecotourism, commitment to sustainability has become a key factor for tourist accommodations. Guests are increasingly valuing green stays that respect the environment, and obtaining certifications that accredit good sustainable practices can be a great competitive advantage.

How to obtain the Biosphere certificate for a rural house?

To obtain the Biosphere certificate, a rural house must demonstrate that it follows a sustainable management model, incorporating good practices in various areas. These practices can be adapted to the characteristics of each accommodation, always ensuring an improvement in sustainability.
1. Sustainable management
It is necessary to establish a sustainability plan that includes environmental, social, and economic management criteria, with actions aimed at reducing environmental impact and promoting responsible tourism.
Possible actions include:
✔ Implementing measures for an efficient use of natural resources.
✔ Training the work team in sustainable best practices.
✔ Carrying out a periodic follow-up of sustainability indicators (water consumption, energy, waste generation, etc.).
2. Energy efficiency
Ensuring energy saving is one of the basic principles of the Biosphere certificate. To achieve this, each accommodation can adopt the solutions that best suit their reality.
Some of the measures that can be implemented are:
✔ Use renewable energies such as solar panels, aerothermal or biomass, if the accommodation considers it viable.
✔ Improve thermal insulation to reduce energy expenditure.
✔ Incorporate LED lighting or saving devices like timers and presence sensors.
3. Water Management
Another key aspect is to ensure a responsible use of water. There are several ways to optimize its consumption, depending on the needs and characteristics of each rural house.
Some actions that can be implemented are:
✔ Install water saving systems such as aerators in taps and showers.
✔ Apply water reuse strategies, such as rainwater collection for irrigation use.
✔ Monitor water consumption to detect possible excesses or leaks.
4. Waste reduction and recycling
Promoting waste reduction and recycling is essential to minimise the environmental impact of the accommodation.
Some actions that can be taken include:
✔ Facilitating the separation of waste through accessible recycling containers.
✔ Reducing the use of single-use plastics and promoting reusable alternatives.
✔ Using eco-friendly cleaning products and sustainable materials in the decoration and maintenance of the house.
5. Protection of the natural environment and biodiversity
Rural houses must ensure the conservation of their natural environment and promote local biodiversity.
Some practices may be:
✔ Preserve the native flora and fauna, avoiding the use of harmful chemicals.
✔ Promote green spaces that favour biodiversity.
✔ Adapt the architecture and construction materials to the natural environment.
6. Social and cultural commitment
Biosphere also values the support for the local community and the promotion of cultural heritage.
Some possible actions are:
✔ Collaborate with local suppliers for purchasing local products.
✔ Publicize the local culture and traditions through activities and information for guests.
✔ Participate in social projects that benefit the community.
7. Boost of responsible tourism
Some possible actions are:
✔ Promote environmentally friendly touristic activities, such as sustainable hiking, cultural routes, or ecological experiences.
✔ Provide information to guests about how they can reduce their environmental impact during their stay.
