According to new analysis by PwC, Brazil and India have an early head start in what could be a green growth race between G20 nations. The PwC Low Carbon Economy Index analyses the G20 against a low carbon economy model, combining both GDP and emissions growth rates. The analysis assessed G20 achievements to date in reducing their carbon intensity levels - the ratio of emissions to GDP - since 2000, and the individual nations' distance to go to meet their carbon reduction targets to 2050. Brazil stood out as a good performer, being the closest to the 2050 low carbon economy goal although challenges around deforestation and land use remain. India is leading for a different reason: the country has low carbon emissions level per capita relative to other emerging economies, and comes out relatively well when comparing carbon intensity across countries.
