This issue of The Circle explores what sustainable shipping entails and how more companies can embrace higher environmental standards. For example, how does shipping interfere with the traditional fishing and hunting activities of coastal and Indigenous communities, and what can be done about it? How can cruise tourism in the Arctic be more sustainable? What are polar fuels, and how steeply might we cut emissions and reduce black carbon if ships began using them?

We also look at why exhaust gas cleaning systems (scrubbers), once seen as a useful way to reduce emissions from burning heavy fuel oil, should be banned to avoid a water pollution crisis, and how the International Maritime Organization’s (IMO’s) proposed measures to reduce the carbon intensity of vessels can benefit marine wildlife.
