In general, we report 100% of the emissions to the environment that result from operations where Repsol has a majority holding and/or operating responsibility. We have a customized computer tool for recording, analyzing, monitoring, and consolidating environmental information, accessible to all of the company's facilities via our intranet, enabling us to upload and validate environmental indicators. We use a common methodology throughout all our lines of business, which is included in the company's Guide to Environmental Parameters and is based on internationally recognized documents and guidelines used in the sector.
