Japan, U.S. and Germany are at the forefront of countries that accumulate innovation patents in renewable energy (wind turbines, photovoltaic, solar, electric vehicles and CO2 capture techniques), followed by South Korea France and the UK.
These six countries gathered 80% of patents for innovations in renewable technologies in the world, said in a joint statement released in Brussels the European Patent Office (EPO), the United Nations Environment Programme ( UNEP) and the Center for Trade and Sustainable Development (ICTSD), who prepared the report.
China, meanwhile, follows in the footsteps of South Korea, specializing in solar photovoltaics.
The analysis draws on some 400,000 patents, there are 60 million internationally, involving the transfer of clean energy technologies like solar photovoltaics, geothermal, solar, wind or CO2 capture techniques.
“Patents play a key role as an indicator of existing technologies, their level of development and geographic expansion,” said the president of the EPO, Benoît Battistelli.
International efforts to combat climate change have triggered technological creativity to find effective solutions that respect the environment, said UNEP executive director Achim Steiner.
The challenge now is to find a way to transfer this technology particularly to developing countries because only then can the climate change adaptation and an effective reduction of pollutant emissions considered ICTSD CEO, Ricardo Meléndez-Ortiz.
The study reveals that the registration of patents related to clean energy rose significantly from 1997 (by 20% annually), with the adoption of the Kyoto Protocol.
Another aspect of the study is exploring licensing the clean energy sector.
According to research, most of these licenses were granted to China, India and Brazil, while only gave very limited in developing countries.
