'Inclusive green growth' is no longer just a buzz term. It is shaping donor priorities, influencing national development plans and attracting investment.

What does Green Economy mean in the context of informal markets where the world's poorest and most vulnerable people produce and trade? Does 'greening' necessitate formalisation, or can it happen through people's own actions?
