Black carbon and the race to save the Arctic

The Arctic is warming up to four times faster than the rest of the planet and shipping’s black carbon emissions are making the problem worse. Our latest report, On Thin Ice: Why black carbon demands urgent action, reveals how the rapid growth of Arctic shipping is speeding sea ice melt, threatening ecosystems, disrupting climate systems and endangering Indigenous and coastal communities. Yet after more than a decade of debate, the International Maritime Organization still hasn’t taken the simple step of requiring ships to burn cleaner fuels in Arctic waters. With shipping traffic up 108% in just over a decade, urgent action is needed now.

For more insight, read our companion blog where Arctic Policy Director Kay Brown explains what black carbon is, why it’s such a growing threat and the concrete steps global regulators must take now to curb its impact.
