As World Environment Day returns on June 5, the global community is uniting to confront an escalating environmental emergency: plastic pollution. Led by the United Nations Environment Programme (UNEP) since 1973, this annual event has become the world’s largest platform for environmental outreach.

The UN General Assembly designated June 5 as World Environment Day to mark the opening of the 1972 Stockholm Conference on the Human Environment, a historic moment that also led to the creation of UNEP. In 2025, the spotlight is firmly on the mounting threat posed by plastics, with the #BeatPlasticPollution campaign taking center stage.

Plastic production has surged dramatically over the past seven decades, causing widespread environmental degradation on a global scale. The Organization for Economic Co-operation and Development (OECD) estimated in 2019, plastic products accounted for 3.4% of global greenhouse gas emissions across their life cycles, with 90% of these emissions stemming from the production and conversion of fossil fuels into new plastics, which exacerbates the climate crisis.

UNEP warns that global plastic use is set to hit 516 million tonnes in 2025, potentially more than doubling to 1.2 billion tonnes annually by 2060. From the Mariana Trench to Mount Everest, plastic pollution is everywhere, and now even detectable in our bodies through microplastics.

Southeast Asia bears a disproportionate burden of this crisis. A 2024 Cornell University study shows that countries like Indonesia, Malaysia, and the Philippines have the highest rates of microplastic ingestion globally.

The implications are dire: microplastics and nanoplastics, byproducts of degrading plastics, can enter the food chain and embed themselves in human tissue. According to OECD, 2.7 million tonnes of microplastics entered the environment in 2020, a figure projected to double by 2040.

In the United States, data from the Environmental Protection Agency (EPA) shows that plastic waste in municipal solid waste systems has steadily increased since 1960, peaking in growth between 1980 and 2000. Public concern is rising in tandem: a 2024 World Wildlife Federation (WWF) survey revealed that 85% of Americans view plastic pollution as a serious issue requiring urgent government action.

But plastic is more than just a waste management concern, it’s also a public health issue. Many plastic products release toxic chemicals throughout their life cycle, from manufacturing to disposal, that endanger both environmental and human health. UNEP identifies over 13,000 chemicals associated with plastics, including 10 high-risk groups such as PFASs, phthalates, bisphenols, and other persistent pollutants. These substances are commonly found in children’s toys, food packaging, cosmetics, and medical devices.

A joint study by Philippines-based NGO BAN Toxics and Bangladesh-based ESDO found hazardous chemicals like arsenic, lead, cadmium, and mercury in plastic toys. Alarmingly, more than 62% of the 257 tested samples exceeded safety limits, posing significant health threats to children and their families.

Meanwhile, recycling remains far from a silver bullet. Only 9% of global plastic waste is actually recycled, and just 21% is deemed economically viable to recycle. Most of the rest pollutes the planet or enters harmful waste streams.

To effectively tackle the plastic crisis, the international community must go beyond recycling and should also address the toxic chemicals in plastics. BAN Toxics calls on the Philippine government to enact stronger regulations on plastic manufacturing and importation, particularly for hazardous types, while pushing for a nationwide ban on single-use plastics and holding corporations accountable for plastic reduction.

On this World Environment Day 2025, the message is clear: it’s time to reflect, act, and demand change. The world must unite to curb plastic pollution before it becomes irreversible. Together, we can #BeatPlasticPollution.
