内容简介:

We employ the ChatGPT model to identify green products in the US product markets. Approximately 3.7% of US product announcements from 2002 to 2022 qualify as green products. Using a stacked Difference-in-Differences approach, we find that firms involved in severe environmental incidents launch 40% more green products

within two years following the incidents. These incident-driven green products are notably novel, supported by high-quality green patents, and result in substantial environmental improvements for both producers and consumers. In contrast, green products introduced without the impetus of environmental incidents do not demonstrate meaningful environmental gains and often raise concerns of greenwashing.
