Every day, cargo ships dock across the Caribbean carrying goods that keep island economies moving—food, medicine, electronics, construction materials, farm supplies and vehicles.
But experts now warn that the region’s next environmental threat may not arrive with sirens, warning labels or flashing lights. It could come disguised as a used vehicle rolling off a cargo ship in Port-of-Spain. A container of pesticides bound for farms in central Trinidad. A shipment of discarded electronics headed for a landfill already struggling for space.
For small island developing states like T&T, where land is limited, enforcement agencies are stretched and ports remain the lifeblood of trade, experts say toxic trafficking is emerging as one of the Caribbean’s most overlooked environmental threats. And it is big business.
“Environmental crime is the fourth most profitable area of crime internationally,” warned Jackline Wanjiru, programme management officer with the Secretariat of the Basel, Rotterdam and Stockholm conventions in Geneva. Wanjiru described this as a global underground trade often linked to organised criminal networks, money laundering and corruption.
Her warning came as customs officers, environmental regulators, agricultural authorities and policymakers from across the region gathered in Trinidad for a workshop hosted by the Basel Convention Regional Centre for Training and Technology Transfer for the Caribbean (BCRC-Caribbean) and the Rotterdam Convention Secretariat, last month.
For the region, representatives from 15 Caribbean Small Island Developing States say the issue is no longer awareness. It is enforcement of international treaties designed to regulate hazardous chemicals, pesticides and waste moving across borders.
“For many Caribbean small island developing states, the challenge is no longer simply awareness of the conventions,” Anand Maraj, acting director of BCRC-Caribbean, told delegates during the workshop’s opening.
“Increasingly, the challenge lies in the operational realities of implementation, coordination, monitoring and enforcement,” Maraj added.
T&T on the front line
As host of BCRC-Caribbean, T&T occupies a unique position in the region’s fight against hazardous chemicals and waste.
Addressing delegates, Sanjay Singh, Permanent Secretary in the Ministry of Planning, Economic Affairs and Development, said Caribbean countries face “real challenges” tied to limited resources, illegal trade and the transboundary movement of hazardous chemicals and waste.
“Strong inter-agency collaboration is essential,” Singh said, noting that customs, health authorities, environmental agencies, agriculture ministries and enforcement officials all have critical roles to play.
For a country with a major industrial sector, active shipping lanes, agricultural communities and growing waste challenges, the issue is hardly abstract.
What toxic trade looks like in the Caribbean
Unlike dramatic images of chemical spills or leaking drums, hazardous trade often arrives in forms most Caribbean people would barely notice.
It can be obsolete pesticides entering agricultural communities. Old refrigerators or air-conditioning units containing ozone-depleting substances. Lead-acid batteries. Discarded televisions and computers. Plastic waste. Industrial solvents. Even second-hand vehicles nearing the end of their useful life.
According to Wanjiru, some of the waste streams most commonly linked to illegal trafficking globally include plastic waste, electronic waste and end-of-life vehicles - the kinds of goods commonly imported into island states with limited disposal and recycling capacity.
“Island nations are quite vulnerable,” Wanjiru said, pointing to limited land space, limited recycling capacity and gaps in enforcement.
Laws lagging behind the trade
At the policy level, regional officials say one of the biggest weaknesses remains outdated legislation.
“A lot of the legislation in the region is outdated,” said Shalina Rooplal, research analyst at BCRC-Caribbean.
“We haven’t seen the legislative backing to properly implement these conventions. There are no enforcement protocols in place, limited human resources, limited funding and infrastructural capacity is also a major issue.”
That challenge is already playing out in countries like Belize.
Aldo Cansino, environmental officer with Belize’s Department of Environment, said while pesticides are regulated, industrial chemicals remain a major blind spot.
“At the moment, we don’t necessarily have an industrial chemicals legislation,” Cansino admitted.
That means authorities often have to piece together information through environmental approvals, ozone programmes and other fragmented systems rather than through one dedicated legal framework.
Belize has already seen firsthand what chemical legacies can look like. During one national disposal effort, officials identified between 25 and 35 metric tonnes of obsolete DDT, a pesticide banned or restricted in many countries, which had to be repackaged and exported for safe disposal.
For Cansino, one lesson from the workshop stood out clearly: “Customs is an integral part of the conversation, because everything comes in.”
While some countries are still building legal frameworks, others are showing what stronger systems can look like.
In Barbados, every pesticide approved for national use is logged on a register shared directly with customs officers.
“Customs, having that list, is able to check as items are coming in,” explained Anthony Headley, director of Barbados’ Environmental Protection Department.
“Where they identify a substance that’s not on the list … it’s detained.”
From there, regulators determine whether the shipment can be registered, repatriated to its country of origin, or exported off-island for disposal under Basel Convention procedures.
Barbados now runs regular public education campaigns to help businesses and workers understand chemical labels, toxicity symbols and safe handling procedures.
A coordination problem
For Mario Yarto, agricultural officer with the Food and Agriculture Organisation and the Rotterdam Convention Secretariat, the biggest challenge is not always identifying dangerous chemicals, but ensuring the agencies responsible for stopping them are actually working together.
“The internal mechanisms to coordinate between the relevant agencies and customs officers are not always effective,” Yarto said.
He pointed to gaps between ministries and agencies that must work together if hazardous chemicals are to be properly monitored and managed.
Yarto said the ultimate goal is not simply stronger institutions, but stronger public awareness.
