This second edition of WIPO’s Green Technology Book is a testament to the collective efforts of innovators paving the way for a more climate-friendly future. From research labs to households, from local communities to global partnerships, the pages that follow celebrate the scope of solutions that form the technological blueprint for reduced greenhouse gas emissions.
