Which factor describes a barrier to adopting sustainable technologies due to cost?

• A. Positive social attitudes
• B. High upfront costs
• C. Ease of transition from routines
• D. All countries have equal access

Answer: (B)

High upfront costs are the clearest barrier to adopting sustainable technologies because the initial investment must be paid before any savings or benefits show up. Even if the long-term operating costs are lower, the immediate capital outlay can deter people or organizations from making the switch, unless financing, subsidies, or favorable cost-benefit analyses are available. The other factors—positive social attitudes and ease of transitioning—make adoption easier rather than creating a barrier, while the idea that all countries have equal access describes a different equity issue rather than a direct cost obstacle.
