This chapter provides an overview about countries’ competitiveness in 14 low-carbon technologies. We calculate the “revealed comparative advantage” (RCA), which measures a country’s degree of export specialization by using gross export data, and the “revealed technological advantage” (RTA), which assess a country’s specialization in innovation by using patent count data. We find that larger countries sustain specializations in several technologies, while smaller countries specialize in fewer technologies. Most countries of the analyzed panel exhibit a specialization in at least one low-carbon technology. Through reliance on a method by Hausmann et al. (2014), we are also able to estimate the “potential revealed comparative advantage” (pRCA) and “potential revealed technological advantage” (pRTA) of a country per low-carbon technology. Certain technologies, such as nuclear, remain exclusive for a small number of countries which are already strong in exporting or innovating nuclear technology. Other technologies, such as “efficient heating and cooling”, “efficient combustion technologies” and “insulation” are promising for several countries in terms of export specialization. The results of this chapter should be interpreted as an indication of where export and innovation potentials exist and could be further exploited. Subsequent country-level analysis is needed to translate these results into concrete recommendations and policy actions.
