Abstract

Key Messages:Innovation is crucial for achieving net zero and tackling climate changeTop R&D firms are central players, generating 67 percent of all high-value green patents between 2012 and 2019Green patenting by R&D companies has declined over time, with no boost after the Paris Agreement in 2015Green technology specialization varies widely across sectors and countriesA clear and stable regulatory framework is key for aligning climate pledges with corporate innovation
