What is the cost of implementing carbon sequestration on a global scale ?
The cost of implementing carbon sequestration on a global scale varies depending on the method used, the location, and other factors. The cost per ton of CO2 removed ranges from $10-$600 for different methods such as afforestation, reforestation, direct air capture, and enhanced weathering. The total cost for global implementation ranges from $100 billion to $6 trillion per year. Several factors affect the cost, including technology development, economies of scale, policy support, social acceptance, and environmental impact. While the initial costs may be high, the long-term benefits of mitigating climate change make it a worthwhile investment.
