Carbon “sinks”, such as forests or the ocean, play a crucial role in absorbing atmospheric CO2 and thereby reducing the damages caused by climate change and the emissions that drive it. However, neither the impacts of global warming nor the carbon sequestration in sinks are equally distributed across the globe. In our new study, published in Nature Climate Change, we map the “blue carbon” uptake from marine and coastal ecosystems around the world to highlight how natural sinks and climate change redistribute wealth around the globe. Our findings show that Australia, Indonesia and Cuba contribute the largest blue-carbon net “wealth” to the rest of the world. However, only a handful of countries have enough blue carbon potential to offset their entire carbon footprint.
