10 times Carnival has come under fire for skirting environmental regulations

Carnival Corp. was fined $20 million last year after Princess Cruises admitted to violating the terms of its probation stemming from its improper waste disposal.

An environmental-compliance inspector found Carnival had released food waste and plastic into the ocean, failed to accurately record waste disposals, created false training records, and secretly examined ships to fix environmental-compliance issues before third-party inspections without reporting its findings to the inspectors.

"These issues were unacceptable failures in our processes that were not in accordance with our policies and procedures, and do not reflect the culture we have built at Carnival Corporation and across our nine cruise line brands," a Carnival representative told Business Insider after the violations were reported by The Miami Herald. "We have been taking steps to address the improvement areas mentioned in the report, and to build on the positive progress noted by the court-appointed monitor to make sure we are in full compliance moving forward."

P&O Cruises' Pacific Explorer ship dumped 59,400 pounds of gray water (which refers to waste generated from sinks, kitchen appliances, and other sources that doesn't include fecal matter) and food waste into the Great Barrier Reef Marine Park in 2018, the Australian government found.

The cruise line told The Guardian in 2018 that the ship had done so accidentally.

Carnival Corp. paid what it characterized as a small fine to the state of Alaska after it and other cruise lines violated the state's air-pollution rules in and before 2015.

The company said in its 2016 annual report that it had started an internal investigation into the issue.

Princess received a $20,000 fine in 2013 after its Golden Princess ship released over 66,000 gallons of water from its pools into Alaska's Glacier Bay National Park & Preserve in 2011.

"We sincerely regret the accidental discharge of swimming pool water that occurred in 2011, and subsequently we took measures to prevent this from happening again," Princess told Cruise Critic at the time.

In 2004, Holland America copped to polluting Alaskan waters in court.

According to the Environmental Protection Agency's web archives, the cruise line was charged with "releasing sewage into harbors" in Alaska. Holland America paid out over $2 million for the violations, split between the state of Alaska, the National Forest Foundation, the federal government, and an environmental compliance program.

Carnival Corp. pled guilty to illegally dumping oily water in the ocean in 2000.

But the South Florida Sun Sentinel reported that there was more to the case than just pollution. The cruise industry giant also admitted to "falsifying log books that are supposed to record all discharges for later review by the U.S. Coast Guard," the Florida newspaper reported.

Carnival Corp. was ordered to shell out a $18 million fine.

According to The Deseret News, Princess Cruises was hit with a $110,000 fee by the Environmental Protection Agency over smokestack emissions standards violations in 2000.

According to the Environmental Protection Agency's web archives, Carnival Cruise Lines was fined $55,000 for violating Alaska's clean air laws in 2000.

Along with Princess Cruises and Carnival Cruise Lines, Holland America was also issued a notice of violation.

The United States Justice Department took the Holland America cruise line to court in 1998 pollution case. A cruise line whistleblower had alerted federal authorities that the cruise line was dumping oily bilge water in the ocean off Alaska. Holland America ended up being ordered to pay $2 million in fines and restitution.
