These ideas might give a sense of direction towards which to steer the G20 in the long run, but they are not easily implementable in the near term. In the near term, the ability to deliver results, the credibility, and therefore the legitimacy, of the G20 could be strengthened by improving existing processes. I see here three important avenues.
First, it is important for the G20 to increase the accountability and transparency of its decision-making process. Vague goals and non-measurable objectives leave too much scope for interpretation and reduce credibility. Recently some progress has been made on agreeing on more concrete objectives.
