Prime Minister Narendra Modi on Friday said parameters used to measure progress are detrimental to the climate and suggested developing the concept of a green gross domestic product. In a free-wheeling conversation with philanthropist and Microsoft co-founder Bill Gates, he also said that climate action has gained momentum since the G20 Summit in India in September last year.

When Gates asked if the green approach could be made more affordable for easier adoption, the prime minister said the world needs to adopt a two-pronged strategy: first, nature- and climate-friendly innovation, and second, environmentally friendly lifestyles.
