In a world where our oceans are grappling with the triple whammy of climate change, geopolitical tensions, and maritime crime, a recent study published in ‘Frontiers in Ocean Sustainability’ (which translates to ‘Frontiers in Ocean Sustainability’) suggests that integrating defense institutions into climate-smart marine spatial planning (CSMSP) could be a game-changer. But it’s not all smooth sailing, as this integration comes with its own set of risks and challenges.
Ralph Tafon, lead author of the study and a researcher at the School of Natural Sciences, Technology and Environmental Studies at Södertörn University in Sweden, argues that bringing defense into the CSMSP fold could accelerate the approval of offshore wind projects, safeguard critical energy infrastructure, and help bridge the defense emissions gap. “Integrating defense into CSMSP offers strategic and climate benefits,” Tafon says, “such as minimizing defense-driven offshore wind cancellation and thus accelerating approval.”
But it’s not all sunshine and rainbows. Tafon warns that this integration could lead to power asymmetries, spatial exclusion, ecological harm, and even the militarization of green energy. To navigate these murky waters, Tafon proposes governance pathways like transparent data sharing, conflict-resolution protocols, and defense marine zoning.
The study also highlights the commercial impacts and opportunities for maritime sectors. For instance, the integration of defense could speed up the approval process for offshore wind projects, benefiting the renewable energy sector. It could also lead to the greening of the military’s supply chains, opening up opportunities for sustainable maritime technologies.
However, Tafon cautions against unbridled enthusiasm. “While green defense initiatives have climate benefits, there are reasons to curb our enthusiasm,” he says. Rising global military spending and the resultant mineral-intensive extractivism could overshadow these benefits by locking in carbon-heavy supply chains and amplifying upstream emissions.
In essence, the study underscores the need for a balanced approach that aligns national security with climate security. It’s a complex issue, but as Tafon puts it, “Aligning national security with climate security thus requires more than technological greening: it requires transparent cradle-to-grave emissions, and strategic restraint in defense spending, war-readiness, and material efficiency.”
So, while the integration of defense into CSMSP presents both opportunities and challenges, it’s clear that the maritime sectors will need to tread carefully to ensure that the benefits outweigh the risks. As Tafon’s study shows, the path to a sustainable and secure future is anything but straightforward.
