Achieving the ambition of limiting global warming to 1.5°C to 2°C by the end of the century as enacted in the Paris Climate Agreement will require massive investments in environmental technologies and a forceful change of path away from high-carbon technologies. This report presents novel descriptive evidence on global trends in patenting in low-carbon technologies, with a particular focus on the energy and road transport sector. The analysis discusses the role of public policies in driving the rate and the direction of innovation for a low-carbon future.
