Our history


Law at the service of the Environment

The International Institute for Law and the Environment (IIDMA) is an independent organisation, founded in January 1997 with the aim of contributing to sustainable development and the protection of the environment, through the analysis, implementation and enforcement of the law.

It is the only organisation of its kind in Spain, having been a pioneer in addressing environmental protection through law. It specialises in the fight against climate change, energy transition, governance and sustainability, water resources, biodiversity and oceans.

Our approach

We work to put law at the service of the environment

Our mission is to contribute to the protection of the environment and promote sustainable development through the research, dissemination, study and development of the law, with emphasis on its correct implementation, compliance and enforcement.

We aim to protect and restore both the environment and natural resources.

This requires that national and international, public and private institutions, as well as citizens, are aware that, by respecting the law, one of the main mechanisms for coexistence and regulation of human conduct, we will be able to transform environmental policies into action and, therefore, into results.



IIDMA was founded in 1997 with the conviction that the implementation of the law is of vital importance to respond to the challenge of protecting our planet. In addition to having been pioneers in Europe, today we are still the only organisation of its kind in Spain.


At IIDMA we design our own projects and, at the same time, we attend to the needs of public and private organisations that require support for the design and implementation of environmental protection mechanisms based on law and policy. IIDMA's work is carried out at international, national and regional levels.

The IIDMA team

IIDMA's team of professionals has specialised training with expertise in international, EU, comparative and national law. It is complemented by an associated team of specialists in social and natural sciences.

Our trajectory

These are just some of the facts that endorse IIDMA’s professional excellence and trajectory. We are proud to be able to add more and more successes every day.
