Parliament and Council negotiators have reached a preliminary agreement on a single European Union methodology for calculating greenhouse gas (GHG) emissions from transport services. The new rules aim to simplify the comparison of environmental performance across different modes of transport in the EU, supporting informed choices by consumers and businesses while addressing concerns about greenwashing.
Under the terms of the agreement, transport companies are not required to calculate their GHG emissions. However, if they choose to do so—whether for reporting, contractual, marketing reasons, or due to other EU regulations—they must use the common EU methodology. This approach focuses on accounting for emissions resulting from vehicle use and energy provision during transport operations.
The agreement emphasizes accuracy by prioritizing primary data over estimates or default values when measuring GHG emissions. It also introduces incentives for operators who directly measure their emissions.
To support small and medium-sized enterprises (SMEs), the European Commission has committed to developing a public, simple, and free calculation tool within four years. This tool will be accompanied by a manual explaining its use, aiming to reduce administrative and financial burdens on smaller companies.
The preliminary deal acknowledges that the current methodology does not include full life-cycle GHG emissions from transport services. Within four years after implementation, the Commission will assess whether it is feasible to expand the methodology to cover life-cycle emissions such as those from vehicle manufacturing, energy production, maintenance, usage, and end-of-life processes. Future updates may be guided by this assessment once sufficient data becomes available and international standards progress.
Environment Committee rapporteur Antonio Decaro (S&D, IT) stated: “With today’s agreement, we are introducing a new regulatory framework that represents an important step forward for the transparency and reliability of environmental data in the transport sector. By promoting the use of primary data, we are ensuring more accurate measurement of greenhouse gas emissions, consistent with Europe’s climate objectives. This also sends a strong signal to consumers, who will be able to make their choices in a more informed and transparent way.”
Transport Committee rapporteur Norbert Lins (EPP, DE) added: “The new rules will make it easier for businesses to report their greenhouse gas (GHG) emissions accurately. The deal includes dedicated incentives for small and medium-sized enterprises (SMEs) to apply the ISO standard without being burdened by excessive administrative tasks. SMEs will also get access to a free calculation tool, making it easier to participate in improved GHG measuring – including when opting to use primary data.
Additionally, life cycle assessment will remain on the table for the near future, signalling ongoing development and consideration in this area. This ongoing evaluation will further enhance the robustness and transparency of emissions calculations as the framework evolves.”
The agreement remains subject to formal approval by both Council and Parliament. If adopted as proposed—with some exceptions—the new rules would take effect four-and-a-half years after publication.
