Graph of the Day: Good Climate Change Policy Spurs Cleantech Innovations

Annex 1 countries which ratified the Kyoto Protocol had a greater share of climate-related inventions, post-Kyoto than the USA & Australia.
Environmental Economics have posted some graphs taken from a new study examining technology transfer and climate change. The gist of it is, that countries that ratified the Kyoto Protocol had greater clean tech innovation in the years after signing than those who did not:It’s important to note that, as the original post author points out,
...the paper doesn't show direct causality. There are hints and some convincing stories to tell, but, as any Wikipedia reader by now knows, statistical correlation doesn't imply causality. More importantly, we may have an entirely different story altogether. It could conceivably be the case that Annex I Kyoto ratifiers (i.e. Europe & Japan) outpaced the United States and Australia in the growth of total patents over these last few years for reasons completely unrelated to Kyoto.
