Using carbon dioxide removal (CDR) strategies to mitigate climate change is a land-intensive endeavor. To capture one gigatonne of CO2 through direct air capture requires a facility & energy production footprint of at least hundreds, but potentially tens of thousands of square kilometers. To capture one gigatonne of CO2 via reforestation requires about 862,000 square kilometers of arable land (nearly the size of the Kalahari Desert). We currently release about 40 gigatonnes of CO2 into the atmosphere every year, so…do the math. And land that is allocated for CDR must compete with other land use claims: for urbanization, agriculture, biodiversity, and renewable energy technologies. But what if our perspective was slightly… more aqueous? Oceans, which make up 70% of the Earth’s surface, already absorb more than 10 billion tonnes of CO2 annually.
