Ensuring the sustainability of SAF feedstock sourcing will be crucial to the success of China's SAF policy. Economic Viability of SAF Adoption The economic viability of SAF adoption is another key concern. While SAF has the potential to reduce the carbon footprint of aviation, its higher production costs and limited availability may make it economically challenging for airlines to adopt SAF on a large scale. There are concerns that the additional costs associated with SAF could be passed on to consumers in the form of higher ticket prices, potentially reducing the affordability of air travel. To address these challenges, China will need to continue investing in R&D to lower the production costs of SAF and explore alternative feedstocks that are both sustainable and economically viable. Additionally, the government may need to provide further financial support to airlines and SAF producers to ensure the long-term success of the policy.
