SNIP: Carbon dioxide emissions from fuel burnt by fishing boats are 30 per cent higher than previously reported.

In a study published in Marine Policy, the scientists show that 207-million tonnes of CO2 were released into the atmosphere by marine fishing vessels in 2016 alone. This is almost the same amount of CO2 emitted by 51 coal-fired power plants in the same timeframe.

“The marine fishing industry relies heavily on the use of fossil fuel and its role in global greenhouse gas emissions has been largely ignored from a policy or management perspective,” said Krista Greer, lead author of the study and a researcher with the Sea Around Us at UBC. “Until now, the most comprehensive study of carbon dioxide emissions from fishing suggested that in 2011, fisheries released 112-million tonnes of CO2 per year from the combustion of fuel during fishing.”

[I]ndustrial fisheries also need to do their part by reducing their fishing effort, which is currently three to four times what it should be in order to be sustainable. This would not only allow for a reduction in CO2 emissions by industrial fleets but would foster the recovery of declining fish populations.
