We are living in an era where pollution and contamination is very high. Rapid and senseless urbanization and industrialization created so many problems for our environment. The deeds of men are making not only his life but also the lives of other creatures on the earth horrible. Having a good knowledge regarding the problems caused by our actions, however small it is, and acting accordingly will help to make the world a better place to live in. The major aim of education is to help one live a better and full life. Thus education in the present century must be founded on the principles of sustainable development and ecological awareness. Teachers are the people who have to create such awareness among the children. Unless one possesses deep knowledge about these areas in its pure sense, he/she cannot teach it. Thus teachers must have good knowledge about the issues and problems caused in the ecosystem by the interventions from the part of human beings. Only then can they educate the children accordingly to make the lives of the future generation safe and better. In his thought-provoking book, Goleman (2009) defines Ecological Intelligence as "individuals' ability to apply what they learn about their impact on the environment to make changes in their behaviour and live more sustainably". The study was aimed to find out the level of Ecological Intelligence of the teachers from the state of Kerala. Cross sectional Survey was carried out using an Ecological Intelligence Inventory (Najmuddeen & Areekuzhiyil, 2013), to collect data from 300 teachers working in Kindergarten to college level, selected through convenience sampling technique. The results of the study showed that teachers possessed higher level of Ecological Intelligence, with female teachers possessing higher level of Ecological Intelligence than the male counterparts. Trained teachers were also found to possess higher level of Ecological Intelligence than those who were not trained. But there was found to be no significant differences in the Ecological Intelligence of the teachers with different duration of teaching experience, age, subject taught and the type of management of the institution. There was found to be no significant differences in the Ecological Intelligence of the teachers with different educational qualifications, but teachers who taught in secondary and higher secondary classes were found to possess higher level of Ecological Intelligence than those who taught in colleges.
