The Pembrokeshire model is based on nine key concepts which, says Clare Williams, should be inherent in the Education for Sustainable Development curriculum. They are:
* Interdependence understanding how people, the environment and the economy are inextricably linked at all levels from local to global
* Citizenship and stewardship recognising the importance of taking individual and collective responsibility and action to make the world a better place
* Needs and rights understanding about human rights, our own needs and the implications for the needs of future generations of actions taken today
* Diversity understanding and valuing human diversity - social, cultural, economic and biological
* Quality of life acknowledging that global equity and justice are necessary in a sustainable society and that quality of life is a broader concept than standard of living.
* Sustainable change understanding that some resources are finite and that this has implications for lasting changes to people's lifestyles and for commerce and industry.
* Uncertainty and precaution acknowledging that there are a range of possible approaches to sustainability and global citizenship and that situations are constantly changing, requiring critical thinking, flexibility and lifelong learning
* Values and perceptions developing a critical evaluation of images of, and information about, the less and more economically developed parts of the world and an appreciation of the effects these have on people's attitudes
* Conflict resolution understanding how conflicts are a barrier to development and a risk to us all and why there is a need for their resolution and the promotion of harmony
