Abstract

The 2021 Intergovernmental Panel on Climate Change (IPCC) report, for the first time, stated that CO removal will be necessary to meet our climate goals. However, there is a cost to accomplish CO removal or mitigation that varies by source. Accordingly, a sensible strategy to prevent climate change begins by mitigating emission sources requiring the least energy and capital investment per ton of CO, such as new emitters and long-term stationary sources. The production of CO-derived products should also start by favoring processes that bring to market high-value products with sufficient margin to tolerate a higher cost of goods.

摘要

政府间气候变化专门委员会（IPCC）2021年的报告首次指出，要实现气候目标，有必要去除二氧化碳。然而，实现二氧化碳去除或减排是有成本的，且成本因来源而异。因此，预防气候变化的明智策略首先是减少每吨二氧化碳所需能源和资本投资最少的排放源，比如新排放源和长期固定排放源。生产二氧化碳衍生产品时，也应优先考虑那些能将高附加值产品推向市场、且有足够利润空间来承受较高产品成本的工艺。
