Paper Abstract: We draw on the textual analysis of patents and corporate reports matched with multi-country, firm-level panel data for the period 2012-2021 to uncover new stylized facts on the emergence and diffusion of green technologies across countries, sectors, and firms. We document a growing importance of green technologies after 2019, Among initially high-emissions firms, those that mentioned green technologies tend to observe a decline in carbon emissions in subsequent years. Buyer-supplier relationships and innovation partnerships with these firms, especially when they had high-emissions intensity, are systematically linked with the diffusion of green technologies.
