    In the Netherlands, agricultural activities are a major source of gaseous emissions of ammonia (NH3), nitrogen oxide (NO), nitrous oxide (N2O), methane (CH4), non-methane volatile organic compounds (NMVOC), CO2 from lime fertilisers and particulate matter (PM10 and PM2.5). The emissions were calculated using the National Emission Model for Agriculture (NEMA). In 2018, NH3 emissions from livestock manure, fertiliser and other sources on farms and hobby farms, from private use and from manure application in terrestrial ecosystems amounted to 118.0 million kg NH3, 2.2 million kg less than in 2017. This decrease was due mainly to the reduction in the size of the dairy herd. Emissions of N2O in 2018 were 20.5 million kg, 0.5 million kg less than in 2017. NO emissions in 2018 amounted to 22.3 million kg, 0.6 million kg less than in 2017. CH4 emissions decreased from 503 to 484 million kg due to the smaller dairy herd. Emissions of NMVOC amounted to 93 million kg in 2018, down from 98 million kg in 2017. Emissions of particulate matter PM10 decreased in 2018 from 6.2 to 5.9 million kg. PM2.5 emissions remained constant at 0.6 million kg. Based on new data for several factors which are described in this report, emission figures have been updated for a number of years in the time series since 1990. NH3 emissions from livestock manure have fallen by two thirds since 1990, mainly as a result of lower nitrogen excretion rates of livestock and the introduction of low-emission manure application. Emissions of N2O and NO decreased over this period by 40% and 33% respectively, less markedly than the NH3 reduction because of higher emissions from manure injection (compared with surface spreading manure) and a shift from excretion on pasture to excretion in animal houses. CH4 emissions decreased by 18% between 1990 and 2018 due to a decrease in livestock numbers and increased feed use efficiency of dairy cattle. PM10 emissions increased by 19% in the same period due to laying poultry farms switching from housing systems with liquid manure to systems with solid manure.

    The ‘Yardstick Sustainable Animal Husbandry’ (in Dutch: Maatlat Duurzame Veehouderij, MDV) already contained a ‘Climate Yardstick’ (in Dutch: Klimaatlat) with some certified measures regarding energy saving and generation of renewable energy. It was desirable to extend this with measures to stimulate the reduction of greenhouse gas emissions from animal houses and manure storages. Some uncertainties about relations between methane, nitrous oxide and ammonia emissions remained after an earlier performed literature review. These relationships were investigated in 6 subprojects. Based on these results some measures were added to the certification scheme. These added measures, however, are limited to systems with liquid manure, in which quick removal of manure from the animal houses is coupled with low-emission storage or manure processing.

    In het kader van de Klimaat- en Energieverkenning (KEV) zijn ramingen gemaakt voor 2020, 2025 en 2030 van i) niet aan energie gerelateerde emissies uit de landbouw naar de lucht, in de vorm van methaan (CH4), lachgas (N2O), ammoniak (NH3), stikstofoxide (NOx), fijnstof (PM10 en PM2,5) en NMVOS (niet-methaan vluchtige organische stoffen) en ii) emissies van kooldioxide (CO2) en N2O door landgebruik, landgebruiksveranderingen en bosbouw (LULUCF). Het jaar 2017 is het basisjaar in de ramingen. De ramingen gaan uit van vastgesteld beleid en van naleving van onderliggende wet- en regelgeving. De peildatum voor het vastgestelde beleid in de raming is 1 mei 2019. De onzekerheden zijn in beeld gebracht voor de factoren met een groot effect op de emissies in 2030. In de raming is de CH4-emissie in 2030 met ruim 32 miljoen kg CH4 afgenomen ten opzichte van 2017 (6,4%). Deze afname wordt veroorzaakt door een afname van het aantal melkkoeien en jongvee. De geraamde N2O-emissie in 2030 is bijna 1 miljoen kg lager (4,5%) dan die in 2017. De grootste afname in N2O- emissie is zichtbaar bij bemesting met kunstmest en bij beweiding. De ammoniakemissie uit de landbouw neemt af van 114 miljoen kg in 2017 naar 109 miljoen kg in 2020 en 101 miljoen kg in 2030. Deze daling hangt samen met meer emissiearme stallen en minder melkkoeien, jongvee en varkens. De NOx-emissie (uitgedrukt in NO) is in 2030 0,7 miljoen kg lager dan in 2017. De emissie van fijnstof (PM10) neemt af van 6,2 miljoen kg in 2017 naar 5,1 miljoen kg in 2030 en die van de fijnere fractie van fijnstof (PM2,5) neemt af van 0,60 miljoen kg in 2017 naar 0,52 miljoen kg in 2030. De totale geraamde emissies uit de LULUCF-sector liggen in de periode 2020-2030 tussen de 5339 miljoen kg en 5707 miljoen kg CO2-equivalenten. Toepassing van de regels uit de LULUCF-verordening van de EU, om de prestaties van lidstaten te beoordelen op de emissies en verwijderingen van CO2 voor de tijdreeks 2020-2030, resulteert in een nettotekort van 316 miljoen kg CO2-equivalenten in 2025 en 258 miljoen kg CO2-equivalenten in 2030. Als prestaties voor de vijfjarige periodes 2021-2025 en 2026-2030 in het kader van LULUCF afgerekend worden, komt dat op een nettotekort van 1500 miljoen kg CO2-equivalent in de eerste periode en van 1200 miljoen kg CO2 equivalent in de tweede periode.

    In many Natura 2000 area’s, the nitrogen deposition is higher than wished for. This led to a deadlock in economic development of,among others,livestock husbandry. For the three sector groups Traffic and Transportation, Industry and Energy, and Agriculture source measures were listedin 2017 to deal with the bottlenecks. For agriculture, the list with measures is updated in consultation with representatives of the agricultural sector, research and policy, developed and written in this present report. This study was performed by order of the Ministry of Agriculture, Nature and Food qualitybefore the Council of State made judgement regarding PAS.

    Agricultural activities are in the Netherlands a major source of gaseous emission as ammonia (NH3), nitrogen oxide (NO),nitrous oxide (N2O), methane (CH4) and non-methane volatile organic compounds (NMVOC) and particulate matter (PM10 andPM2.5). The emissions in 2017 were calculated using the National Emission Model for Agriculture (NEMA). The method calculatesthe NH3 emission from livestock manure based on the total ammonia nitrogen (TAN) content in manure. In 2017 NH3 emissionsfrom livestock manure, fertilizer and other sources in agriculture, from hobby farms, private parties and manure application onnature areas amounted to 120.5 million kg NH3, 3.9 million kg more than in 2016. Nitrogen excretion increased due to a largerfeed requirement for dairy cows and higher nitrogen levels in roughage. N2O emissions in 2017 were 21.3 million kg, slightlyabove the level of 2016 (20.7 million kg). The NO emission in 2017 amounted to 23.1 million kg compared to 22.5 million kg in2016. The CH4 emission decreased due to the shrinking of the dairy herd from 508 to 503 million kg. NMVOC emissionsamounted to 98 million kg in 2017 compared to 99 million kg in 2016. Emissions of particulate matter PM10 and PM2.5, 6.2 and0.6 million kg respectively, hardly changed compared to 2016. Some figures in the time series 1990-2016 were revised onbasis of new insights. NH3 emissions from livestock manure in the Netherlands dropped by two thirds since 1990, mainly as aresult of lower nitrogen excretion rates by livestock and low emission manure application. Emissions of N2O and NO alsodecreased over the same period, but less strongly (38% and 31% respectively), due to higher emissions from manure injectioninto the soil and the shift from poultry housing systems with slurry manure towards solid manure systems. CH4 emissions reducedby 14% between 1990 and 2017, caused by a decrease in livestock numbers and increased feed efficiency of dairy cattle.

    This research makes an inventory of technical measures which are able to reduce the methane emissions of the Dutch livestock production systems (i.e. cattle and pig farming): breeding, composition and quality of feed, use of inhibitors, frequent manure removal from barns, manure additives, manure mixing and aeration, manure cooling, anaerobic digestion, methane oxidation. Through a literature study and expert consultation a qualitative assessment framework has been developed and applied to evaluate different sustainability and ethical aspects of these measures. This has been conducted from the perspective of different stakeholders

    The National Emission Model for Agriculture (NEMA) is used to calculate emissions to air from agricultural activities in the Netherlands on a national scale. Emissions of ammonia (NH3) and other N compounds (NOx and N2O) are calculated for animal housing, manure storage, manure application and grazing using a flow model for total ammoniacal nitrogen (TAN). Emissions from the application of inorganic N fertilizer, compost and sewage sludge, cultivation of organic soils, crop residues, and ripening of crops are calculated as well. The NEMA is also used to estimate emissions of methane (CH4) from enteric fermentation and manure management, nonmethane volatile organic compounds (NMVOC) and particulate matter (PM) from manure management and agricultural soils, as well as for carbon dioxide (CO2) from liming. Emissions are calculated in accordance with the criteria of international guidelines and reported in an annual Informative Inventory Report (IIR; for air pollutants) and National Inventory Report (NIR; for greenhouse gases). This methodology report provides an outline of and describes the background to the calculation of emissions according to the NEMA.

    Ammonia emission intensity - Animal protein - Feed nitrogen - Manure management - Nitrogen use efficiency

    The increasing global demand for food and the environmental effects of reactive nitrogen losses in the food production chain, increase the need for efficient use of nitrogen (N). Of N harvested in agricultural plant products, 80% is used to feed livestock. Because the largest atmospheric loss of reactive nitrogen from livestock production systems is ammonia (NH3), the focus of this paper is on N lost as NH3 during the production of animal protein. The focus of this paper is to understand the key factors explaining differences in Nitrogen Use Efficiency (NUE) of animal production among various European countries. Therefore we developed a conceptual framework to describe the NUE defined as the amount of animal-protein N per N in feed and NH3–N losses in the production of milk, beef, pork, chicken meat and eggs in The Netherlands, Switzerland, United Kingdom, Germany, Austria and Denmark. The framework describes how manure management and animal-related parameters (feed, metabolism) relate to NH3 emissions and NUE. The results showed that the animal product with the lowest NUE had the largest NH3 emissions and vice versa, which agrees with the reciprocal relationship between NUE and NH3 within the conceptual framework. Across animal products for the countries considered, about 20% of the N in feed is lost as NH3. The significant smallest proportion (12%) of NH3–N per unit of Nfeed is from chicken production. The proportions for other products are 17%, 19%, 20% and 22% for milk, pork, eggs and beef respectively. These differences were not significantly different due to the differences among countries. For all countries, NUE was lowest for beef and highest for chicken. The production of 1 kg N in beef required about 5 kg N in feed, of which 1 kg N was lost as NH3–N. For the production of 1 kg N in chicken meat, 2 kg N in feed was required and 0.2 kg was lost as NH3. The production of 1 kg N in milk required 4 kg N in feed with 0.6 kg NH3–N loss, the same as pork and eggs, but those needed 3 and 3.5 kg N in feed per kg N in product respectively. Except for beef, the differences among these European countries were mainly caused by differences in manure management practices and their emission factors, rather than by animal-related factors including feed and digestibility influencing the excreted amount of ammoniacal N (TAN). For beef, both aspects caused important differences. Based on the results, we encourage the expression of N losses as per N in feed or per N in product, in addition to per animal place, when comparing production efficiency and NUE. We consider that disaggregating emission factors into a diet/animal effect and a manure management effect would improve the basis for comparing national NH3 emission inventories.
