Launched by Prime Minister Narendra Modi of India, the Lifestyle for Environment (LiFE) initiative aims to encourage the adoption of sustainable lifestyles in India and internationally to tackle the challenges of environmental degradation and climate change. This report examines how India has integrated several policies in its energy transition strategy that are aligned with the LiFE initiative, highlighting the potential for behavioural change and consumption choices to help advance energy transitions globally. It then analyses the impact on energy consumption, costs and emissions of measures like those proposed by the LiFE initiative, such as buying an EV or taking public transport, if they were adopted globally. Finally, it considers how India’s first G20 Presidency could strengthen the LiFE initiative by anchoring it in the G20’s current framing of energy transitions and initiating processes to gather experience and best practices of policies and programmes that G20 members are already conducting.
