On Finance Day the previous week, the Climate Compatible Growth programme hosted a side event on the GGI, organised by the Climate Parliament and with speakers including Members of Parliament from India and the UK, and the Commissioner of the California Public Utilities Commission. Panellists discussed progress made and research underpinning the initiative, the challenges of building green grids, what needs to be done, and how by working in partnership with a multiplicity of actors, we can accelerate the global energy transition.
