Next week’s high-level summit in Paris for a New Global Financing Pact seeks to find ways to reform the global financial system to simultaneously address climate change, biodiversity, and sustainable development challenges worldwide.

A team of researchers from the Stockholm Environment Institute offers ideas to better steer financial resources to address these intertwined global crises.
