A quarter of a century ago, the Brundtland report introduced the concept of sustainable development to the international community as a new paradigm for economic growth, social equality and environmental sustainability. The report argued that sustainable development could be achieved by an integrated policy framework embracing all three of those pillars. The Brundtland report was right then, and it remains right today. The problem is that, 25 years later, sustainable development remains a generally agreed concept, rather than a day-to-day, on-the-ground, practical reality.
