Strengths

• unique solution
• ‘proven technology’
• no complex technology
• comparative low CO₂ emission and low energy requirements
• a variety of applications
• not any dangerous byproduct
• relatively cheap
• easy upscalable
• sustainable
• politically neutral

Weaknesses

• widespread unfamiliarity with this solution
• credibility and proof
• not ‘innovative’ (in the sense that it is a known natural process)
• weathering process is relatively slow
• measurability
• utilization to its full extent requires a global approach
• lack of own means and Calimero effect

Opportunities

• necessity of a continued use of fossil fuels
• biomass is not really a ‘carbon sink’
• negative publicity related to CCS
• ‘development aid = carbon credits trade’
• climate crisis
• Kyoto/Copenhagen
• national ambitions
• green lobbies

Threats

• large scale CCS
• conservatism and tunnel vision of public authorities
• NIH syndrome
• many followers imitators and competitors
• air pollution hype
• no complete answer to the question ‘why not yet widely used’
• alternatives such as biochar (terra preta)
