World Environment Day History

The origin of World Environment Day dates back to 1972, when the United Nations Conference on the Human Environment was held in Stockholm. That same year, the UN General Assembly declared 5th June as World Environment Day. The first celebration happened in 1973, with the theme “Only One Earth.”

Since then, World Environment Day has become the largest global platform for environmental outreach. Every year, the campaign is led by a host country, which drives awareness around a specific theme. It not only educates people but also pushes governments to bring real policy changes. 

The day is now observed in over 150 countries, inspiring clean-up drives, plantation efforts, awareness campaigns, school activities, and eco-friendly pledges.

World Environment Day Theme 2025

“Beat Plastic Pollution” is the theme for World Environment Day 2025, carried forward under the campaign slogan #BeatPlasticPollution. This theme highlights a global crisis threatening our ecosystems, marine life, and human health.

Plastic pollution is visible everywhere, in oceans, on roadsides, and even in remote forests. Particularly, single-use plastics are more harmful, as they break down into microplastics that stay in the environment for hundreds of years. The 2025 theme calls on every stakeholder, from individuals and companies to policymakers, to reduce plastic waste.

World Environment Day 2025 theme promotes sustainable alternatives like cloth bags, reusable containers, and biodegradable packaging. The campaign encourages everyone to make mindful choices that reduce plastic consumption.

Plastic Pollution in India

India is responsible for nearly one-fifth of the total plastic waste produced globally. The country generates nearly 9.3 to 9.5 million tonnes of plastic waste every year. This includes around 0.12 kg/day of per capita waste generation. 

The plastic pollution is harmful in many ways:

• Plastic litter clogs drains, harms wildlife, and contaminates soil and water. 

• Close to 5.8 million tonnes of plastic waste are burned annually, releasing toxic pollutants

• Urban areas, especially metros like Delhi, Mumbai, and Bengaluru, face major waste management challenges. 

• It affects India’s vast coastline, as marine species often consume plastic, mistaking it for food, which disrupts the marine ecosystem.

To tackle this, India must enforce stricter plastic bans, improve recycling systems, and involve citizens in community-level clean-up and waste management efforts.

Measures to Curb Plastic Pollution

India is taking steps to reduce plastic waste, both at the national and local levels. Some effective and innovative initiatives include:

• Plastic roads: Cities like Ahmedabad are using shredded plastic waste in road construction. This not only reuses plastic but also increases road durability.

• Railway initiatives: In Bhopal, Indian Railways has launched campaigns for tree plantation, water conservation, and plastic-free stations.

• Reverse vending machines: In Karnataka, authorities have installed machines that offer ₹1 in exchange for plastic bottles, encouraging recycling.

• Eco-tourism zones: In Coimbatore, forest officials collected over 11 tonnes of plastic from trekking areas and introduced deposit-return schemes for plastic bottles.

• School awareness programs: Several states are introducing plastic-free campaigns in schools, making young students part of the solution.

• Extended Producer Responsibility (EPR): Holds manufacturers accountable for the lifecycle of their products, including collection and recycling.
