The G-20 summit in London acknowledged interdependence between countries and a need for greater cooperation to reform the global financial system. Leaders endorsed building a resilient, sustainable and low-carbon economy, and reaffirmed their commitment to address climate change at the upcoming UN conference. Commitments of $5 trillion are expected to raise global output by 4% and accelerate the transition to a green economy. Immediate reforms included additional voting representation and funding for the IMF and World Bank. However, more fundamental reforms such as redesigning debt-based money and banking or creating a new global reserve currency were not addressed.
