This paper identifies over 50 000 patents filed worldwide in various water-related adaptation technologies between 1990 and 2010, distinguishing between those related to water availability (supply) and water conservation (demand) technologies. The paper then analyses the innovation activity –...

Can directed technical change be used to combat climate change? We construct new firm-level panel data on auto industry innovation distinguishing between "dirty" (internal combustion engine) and "clean" (e.g. electric and hybrid) patents across 80 countries over several decades. We show that...
