Understanding the Dutch Government's CO2 Reporting Requirements
In response to the growing concerns about climate change and the Netherlands' commitment to reducing CO2 emissions, the Dutch government introduced new legislation to monitor and manage the environmental impact of work-related travel. This legislation, known as the "Rapportageverplichting werkgebonden personenmobiliteit (WPM)", mandates organisations with a workforce of 100 or more to provide detailed reports on the CO2 emissions resulting from their employees' business and commuting travels.
Starting from 1 January 2024, if your organisation falls into this category, you'll be required to maintain a record of the CO2 emissions from both business trips and daily commutes of your employees. This data will play a crucial role in the country's efforts to understand and reduce the carbon footprint of work-related travels, which currently account for a significant portion of the total kilometers driven in the Netherlands. The deadline for submitting the required data for the year 2024 is set for 30 June 2025.
This move by the government not only emphasizes the importance of environmental responsibility but also underscores the role employers play in promoting sustainable travel options and practices.
For a comprehensive understanding of these requirements and to ensure your organization remains compliant, the official RVO website offers detailed insights.

ESG stands for Environmental, Social, and Governance.
In the context of expense management, every business trip, supplier choice, or expense category can influence a company’s environmental footprint or social responsibility record.
By capturing ESG data at the transaction level (such as CO₂ emissions from travel or the sustainability rating of a vendor) finance teams gain the insights they need to track impact, enforce policies, and report accurately.
