Dr. McKeown-Ice has been one of the pioneers in education for sustainable development (ESD), and her understanding of ESD has evolved with the times. In today’s world, ESD has become part of educating for a more uncertain future; it includes educating for agency, adaptive competence and compassionate systems. The demonstration of ESD producing outcomes that characterise quality education, plus the examples and tools offered by Dr. McKeown-Ice, shall encourage teachers of any discipline to incorporate sustainability to their own teaching. What is also inspiring, and admirable, is how Dr. McKeown-Ice applies the Earth Charter in education on both macro and micro levels. Envisioning the future of education, she calls for attention to contextual variability, technological impact, and compassionate systems thinking.
