Cambodia is set to join the global community in commemorating National and World Environment Day on June 5, under the theme “Beat Plastic Pollution”, as part of a worldwide effort to address one of the most pressing environmental challenges of the modern era.
World Environment Day, established by the United Nations in 1972 after the landmark United Nations Conference on the Human Environment, has evolved into the largest global platform for environmental outreach.
First celebrated in 1973, this international observance engages more than 150 countries each year and is coordinated by the United Nations Environment Programme (UNEP). Each year, UNEP selects a specific theme and rotating host country to emphasise urgent environmental issues and promote innovative, actionable solutions.
The 2025 observance highlights plastic pollution — an escalating global crisis. In recent decades, plastic production has increased significantly due to its low cost, durability, and versatility. However, these same attributes have led to its pervasive presence as a lasting pollutant in natural ecosystems.
Each year, over 400 million tonnes of plastic waste are produced globally, with an estimated 75 to 199 million tonnes entering the oceans. This influx has severely disrupted marine ecosystems and posed serious risks to sea life and seabirds.
In addition to ecological damage, plastic breaks down into microplastics and nanoplastics, which have been found in air, water, and food, raising significant public health concerns. The economic impact is also substantial, affecting tourism, fisheries, and healthcare systems worldwide.
Southeast Asia is a significant contributor to marine plastic pollution. Rapid economic growth, urbanisation, an increased reliance on single-use plastics, and underdeveloped waste management infrastructure have all exacerbated the issue. Major regional rivers, such as the Mekong, act as key conduits for plastic waste flowing into the ocean.
Coastal areas and islands in the region are increasingly facing the burden of plastic accumulation, which not only mars natural beauty but also threatens the sustainability of tourism-dependent economies.
The 2025 campaign calls for a collective commitment to reducing plastic consumption, enhancing waste management systems, and adopting sustainable alternatives to safeguard both human and environmental health.
During interviews on Friday, the Ministry of Environment spokesman, Khvay Atitya, urged for unity in the effort to maintain Cambodia’s cleanliness and greenery.
King Norodom Sihamoni will preside over the event at the Win-Win Memorial in Phnom Penh.
