- Abstract:
- Carbon removal, which involves capturing carbon dioxide (CO2) from the atmosphere and sequestering it, can help us meet the goals of the Paris Agreement. The key question is not just how to make large-scale carbon removal operational, but how to make it sustainable. Sustainable practices balance environmental, social, and economic goals. Sustainable carbon removal balances those goals in order to meet the needs of the future without compromising the ability of current generations to meet their own needs. To operationalize this idea, we need to ask two questions: How should we measure the environmental, social, and economic impacts of carbon? How should we decide when carbon removal strikes the right balance between future and present needs? Analyzing carbon removal at different levels can illuminate environmental, social, and economic risks and opportunities. Levels of analysis range from broad technological categories, like reforestation, to specific projects, like Climeworks’ Orca direct air capture project in Iceland. Most analyses have focused on broad technological categories, but more fine-grained analyses are crucial for delivering actionable advice. Finding metrics for environmental, social, and economic impacts is vital for quantifying positive and negative impacts and comparing approaches. One possibility is to use the indicators for the UN’s Sustainable Development Goals, which are politically negotiated, internationally accepted metrics of environmental, social, and economic sustainability. Determining which approaches are most sustainable requires balancing different positive and negative impacts that may not be easily comparable. There are several ways to do this, ranging from intuitive judgments to multicriteria decision analysis, although any decisions about which approaches are most sustainable are ultimately political decisions. In summary, to develop sustainable carbon removal, we need to identify sustainability metrics, such as the indicators behind the Sustainable Development Goals; apply those metrics at different levels of analysis; and develop strategies for determining which approaches strike the right balance between environmental, social, and economic goals.
