NASA Releases Satellite Evidence of 2020 IMO Benefits

WE space exploration corps Nasa released new evidence showing the impact of IMO 2020 emissions change for shipping.

A new NASA study has shown that ship trajectories — lines of clouds formed by water vapor interacting with ship exhaust, visible in satellite images — have shrunk dramatically since the change. The IMO has reduced the global sulfur content limit for bunker fuel by 3.5% at 0.50% since the beginning of 2020.

Previous emissions regulations for shipping such as the 0.1% emission control area in North America of 2015 didn’t have the same impact, as ships changed routes and took longer courses to avoid the stricter rules whenever possible, the NASA researchers found.

Whereas COVID-19[feminine] may have played a role in reducing maritime activity in 2020, the IMO 2020 regulations played the dominant role in reducing ship lanes, NASA said in a statement posted on its website Tuesday.

“Analyzing data from 2020, researchers found that shipping lane density dropped that year across all major shipping lanes,” the organization said.

“Vessel-based tracking data indicated that the COVID-19 pandemic played a role in reducing global maritime traffic by 1.4% for a few months.

“But this change alone could not explain the sharp decrease in observed ship trajectories, which remained at record highs for several months of 2021 (the most recent data analyzed).

“Researchers concluded that new global fuel regulations played the dominant role in reducing vessel routes in 2020.”
