Figure TS.6: The technology development cycle and its main driving forces [Figure 2.3].

Note: important overlaps and feedbacks exist between the stylized technology life-cycle phases illustrated here. The figure therefore does not suggest a ‘linear’ model of innovation. It is important to recognize the need for finer terminological distinction of ‘technology’, particularly when discussing different mitigation and adaptation options.
