A circular economy approach addresses the entire value chain, from sustainable design and production to consumption, collection, sorting, recycling, and reuse, ensuring that plastic resources are managed efficiently throughout their lifecycle.

The 'Reduce, Reuse, Recycle' (3R's) principle is fundamental to a circular economy, aiming to keep resources in use for as long as possible, extract the maximum value from them whilst in use, then recover and regenerate products and materials at the end of each service life.

The policy aims to transition from a linear to a circular economy for plastics, focusing on reducing waste, increasing recycling rates, and promoting the reuse and recovery of plastic materials.

Scientific consensus points to global warming and climate change as the primary drivers of accelerated glacial melt worldwide, including in the Himalayas, due to rising global temperatures.

The Indus, Ganga, and Brahmaputra rivers are all major transboundary rivers originating in or significantly fed by the Himalayan glaciers. The Godavari River, however, originates in the Western Ghats of India.

Himalayan glaciers are a crucial source of water for major river systems in Asia. Their accelerated melt threatens long-term water security for millions who depend on these rivers for drinking water, irrigation, and hydropower.

CREM directly contributes to India's efforts in climate change adaptation by strengthening coastal ecosystems against extreme weather events and supports biodiversity conservation by protecting critical marine habitats.

CREM focuses on ecosystem restoration, which includes activities like mangrove plantation, coral reef conservation, and protection of other critical coastal habitats to build natural resilience.
