When talking about environmental legislation, the list is endless; there are numerous laws, decrees, and regulatory bodies that safeguard environmental protection. Therefore, below is a brief overview of the key environmental legislation you need to know, closely related to sustainability:

• Law 8/2003, of October 28, on Wild Flora and Fauna: This law in Spain laid the foundation for the protection of biodiversity and the species that make up ecosystems, highlighting environmental concerns. It is essential to know this law as it defines all the possible impacts on the environment and related infractions. It serves as the basis for understanding other legislation.
• Law 42/2007, of December 13, on Natural Heritage and Biodiversity: This law forms the basis for sustainability and biodiversity management within Spanish territory. While the previous law established the foundations for environmental protection and related infractions, this law emphasizes the ecological wealth and biodiversity of the country, describing it in more detail. It set the basic legal framework for the conservation and sustainable use of natural heritage, as well as the restoration of biodiversity.
• Law 21/2013, of December 9, on Environmental Assessment: This law establishes the environmental impacts of various projects, making it fundamental to know for continuing business activities. It guides how to proceed when a project has environmental implications and how to properly plan it. For example, if your company is dedicated to renewable energy production, this legislation defines the limits on where a photovoltaic park can be located. If the project affects any area within the Natura 2000 network, the project will be completely halted, as neither Spain nor the European Union will allow it to continue, with serious consequences.
