As nations prepare to address multiple crises and mitigate the negative impacts of climate change, it has become increasingly clear that the current multilateral system and established global governance mechanisms are inadequate. This chapter thoroughly examines an innovative approach called Lifestyle for Environment (LiFE) introduced by India and explores its practical implementation to effectively address global challenges. Drawing on the concept of Prakriti Rakshati Rakshita—those who protect nature, nature protects them, the chapter advocates for promoting sustainable consumption and production by encouraging affluent individuals and groups to adopt lifestyles that minimise environmental harm. This approach, centred around a people-focused LiFE framework, emphasises the significance of regenerative resource processes in human development, with humans acting as stewards responsible for creating a just and sustainable future. To achieve this, the operationalisation of the LiFE approach requires a focus on the 4Cs—cooperation, coherence, convergence, and commitments.
