The impact of a modal shift in transport on emissions to the atmosphere: Methodology development for the best use of the available information and expertise in the Danube Region.

A modal shift in transport can represent a promising option where the economic added value is demonstrated. However, the impact of this action on the environment is important as well. In the framework of the JRC scientific support to the Danube Strategy, the EDGAR modal shift initiative focuses on the emissions evaluation for ex-post modal shift scenarios, as a contribution to the Danube Air Nexus. Given the complexity of this topic, a methodology for the best use of the available information and expertise in the Danube Region has been developed and is presented in this report. This work is the outcome of the joint efforts of the JRC/EDGAR team, country emission experts and relevant institutions in the Danube Region. It shows that, in addition to the EDGAR data and gridding tool, the participation by and contributions of experts from the Danube Region is essential in compiling emissions from the transport sector and enriching knowledge of variations in national circumstances, on inland domestic and international shipping and by bringing details of ship and truck freight transport. Considering the transboundary characteristics of the transport sector, the EDGAR team developed a Web-based emissions gridding tool (EDGAR.ms) to be used by experts, institutions and authorities in the region to distribute emissions from road transport sector in a consistent manner. Emission experts from four countries (Hungary, Romania, Serbia and Croatia) tested the EDGAR.ms tool with their national data and this user friendly application is now available to all country emission experts in the Danube Region (upon request). Regarding navigation, the contribution of Viadonau and Danube Commission is essential to evaluate ship emissions. It is appreciated that, this scientific network, which includes both EU and Non-EU countries, has the capability to explore and evaluate emissions changes from a modal shift in transport and to identify the advantages and drawbacks related to emission patterns changes but to be fully comprehensive, this undertaking requires participation/contribution from specialized institutions in the region and country emission experts from the entire Danube Region.JRC.H.2-Air and Climat

Quality assurance of the Serbian national E-PRTR register reported data for large combustion plants

U periodu od 2007. do 2009. godine, a radi kontrole i ograničenja emisije iz industrije u skladu sa Pravilnikom o metodologiji za izradu integralnog katastra zagađivača, za potrebe Integralnog katastra zagađivača niz postrojenja su bila dužna da dostave podatke o količinama zagađujućih materija ispuštenih u vazduh i vode, kao i o generisanju otpada. Ovaj registar je sastavni deo informacionog sistema zaštite životne sredine Republike Srbije, koji vodi i čiju kontrolu podataka vrši Agencija za zaštitu životne sredine. Cilj ovog rada je kvalitativna analiza podataka o emisiji zagađujućih materija u vazduh (SOx, NOx i praškaste materije), na osnovu dostavljenih podataka za 2009. godinu. Proračun emisija je izvršen na osnovu metodologije koja je propisana Konvencijom o prekograničnom zagađenju vazduha na velikim udaljenostima. Radom su obuhvaćena velika ložišta sa izlazom toplote većim od 50 MW. Analiza je obuhvatila 37 postrojenja sa ukupno 61 emiterom.The Serbian E-PRTR register (The European Pollutant Release and Transfer Register) was established in 2007 and harmonized with PRTR protocol of Arhus convention and E-PRTR directive. In this paper, the quality of 2009 data reported to the Serbian PRTR register was analyzed. The analysis includes 37 large combustion plants with the capacity equal or greater than 50 MW. The combustion plants include power plants, heating plants and industrial energy units. The calculation is done using EMEP-EEA 2009 methodology and Tier 2 approach. The analysis obtained presents an overview of the quality of the reported data for SOx, NOx and TSP emissions for 61 combustion units, e.g., emitters (stacks). The results show that all 61 emitters reported data with the deviation greater than 25%, with 55% of the emitters reporting data that differed from pollutant to pollutant in comparison to the estimated data. Out of those, 30% of the emitters reported smaller and 8% reported greater emissions than estimated emissions with 7% of the emitters not submitting any emissions data. The analysis also includes calculation of the emissions scope limit within 95% confidence interval. According to these results, it can be concluded that only 15% of the emitters have emission levels that fall within the scope limits, 47% of the emitters reported data of which two data fall within the scope limits, 28% of the emitters reported data of which only one data fall within the scope limits, 3% of the emitters had data that didn't fall within the scope limits, and 7% did not reported any emission data. The results of the analysis can be summarized as: 1) operators in facilities do not know how to calculate emissions from their sources, and 2) the application of global emission factors can lead to considerable errors. The main reasons for significant deviation are different fuel quality, type of technical units and human error, thus national emission factors should be developed
