This study aims to explore the relationships between digital technologies, climate adaptation and mitigation efforts, and firm productivity using survey data from over 25,000 firms across Europe and the US. The results show that more digitally advanced firms are more likely to undertake both climate adaptation and mitigation simultaneously, and do so at a higher intensity. However, climate adaptation efforts remain low overall. The relationships between digital technologies and climate responses are also shaped by firms' perceptions of climate change impacts and transition risks/opportunities. The findings provide evidence that digital technologies can help firms better recognize needs and opportunities for climate action and intensify their engagement in adaptation and mitigation.
