The government of Belize has not put into place promised protections for the Belize Barrier Reef World Heritage site, leaving the largest barrier reef in the western hemisphere under threat from offshore oil drilling and damaging coastal construction, according to a new WWF assessment.

Key concerns include a lack of progress over the last year on legislation to ban offshore oil exploration and production within the reef site and buffer areas, despite a government announcement of the ban in 2015. And there’s also no legislation to prohibit the sale of public land in the World Heritage site. In 2015, the Belizean government committed to taking such measures by last December.

“Seven months on, Belize has not delivered on its promise to protect the Belize Barrier Reef,” said Nadia Bood, a Mesoamerican Reef scientist at WWF. “Instead, this remarkable ecosystem — vital to both wildlife and the country’s economy — remains under threat. We urge Belize’s government to act immediately to safeguard the reef for future generations.”
