(68)Digital tools and technologies, such as those used for tracking, surveillance or tracing raw materials, goods and products throughout value chains, for instance satellites, drones, radars, or platform-based solutions, could support and reduce the cost of data gathering for value chain management, including the identification and assessment of adverse impacts, prevention and mitigation, and monitoring of the effectiveness of due diligence measures. In order to help companies fulfil their due diligence obligations along their value chain, the use of such tools and technologies should be encouraged and promoted. To that end, the Commission should issue guidelines with useful information and references to appropriate resources. When using digital tools and technologies, companies should take into account and appropriately address possible risks associated therewith, and put in place mechanisms to verify the appropriateness of the information obtained.
