Globally, the pace of technology diffusion has accelerated over the past 200 years. The acceleration is especially striking in certain sectors. However, technology deployment in non-developed countries is comparatively slow, particularly in developing countries. Only 36% of emerging and developing countries have reached the 25% penetration threshold and only 9% have reached the 50% threshold for the technologies invented between 1975 and 2000 . This deployment speed is detrimental to the cause of tackling climate change. Its impacts on emerging and developing countries are especially harmful, because the bulk of technological progress in these countries comes from the adoption and adaptation of pre-existing but new-to-market technologies, and through the spread of technologies across firms, individuals, and the public sector within a country.
