In fact, innovation is critical for sustainable development precisely because it is our best chance to mitigate and even eliminate tradeoffs between economic prosperity, environmental sustainability and social inclusiveness. For instance, the global market in sustainable materials and energy efficiency, pollution prevention and various consumptive uses of environmental qualities constitutes about 2.9 trillion US Dollars a year. This market for sustainable innovations grows faster than the global economy as a whole with renewable energy being among the fastest growing market segments (even outpacing growth in the ICT sector). The main rationales for supporting innovation policies from a purely economic development perspective are market and coordination or systems failures.
