They gather information from the shipping press, specialist publications, from vessel owners, their insurers and from ITOPF's own experience at incidents. Even though some smaller spills may have been missed, reporting has improved so they are more likely to be included in more recent data.\n\nTwo independent experts we contacted recognized ITOPF as a reliable source and agreed that the number of oil spills had been declining as we describe in our question. \n\n[1]  [International Tanker Owners Pollution Federation (ITOPF) - Tanker spills from 1970 to 2022](https:\u002F\u002Fwww.itopf.org\u002Fknowledge-resources\u002Fdata-statistics\u002Fstatistics\u002F)\n[2]  We consulted two independent experts for this question, including Ida-Maja Hassellöv of Chalmers University of Technology.","In the 1970s, there were an average of 78 oil spills from tankers per year. Just three decades later, it had dropped to fewer than 7 per year. \nThis is a result of better legislation leading to safer transportation with ships equipped with double engines, generators and better-trained crews. The total amount of oil spilled has also decreased. This improvement is worth celebrating. It shows that environmental disasters can be prevented when industries are committed to a goal and regulators learn from experience and update the rules so that the causes of previous accidents are eliminated.\n\n### Why are people wrong about this?\nWhen problems are prevented, people usually don't hear about them. Oil spills that do not happen are never reported in the news, which is why most people completely missed this big improvement!\n\n### Why is it important to know this?\nMany people lose hope about the environment and it's important to realize that effective regulations can have a huge impact. The reduction of oil spills is one such example that should inspire people to imagine that other forms of environmental disasters can also be prevented.\n\n### Can I trust this data?\nYes. If some oil spills are not included in this data it is probably an oil spill that went unreported some decades ago, before the Internet. Today, it's nearly impossible for an oil ship to leak without getting lots of media attention.","Most spills didn't happen","Effective regulations have made oil spills very rare, but you completely missed this big improvement!"]
