Abstract Nitrous oxide (N2O) is one of the main greenhouse gases, with a nearly 300 times greater potential to produce a greenhouse effect than carbon dioxide (CO2). Almost 80% of the annual emissions of this gas in Poland come from agriculture, and its main source is the use of agricultural soils. The study attempted to estimate the N2O emission from agricultural soils and to indicate its share in the total greenhouse gas emissions in 48 Polish communes. For this purpose, a simplified solution has been proposed which can be successfully applied by local government areas in order to assess nitrous oxide emissions, as well as to monitor the impact of actions undertaken to limit them. The estimated emission was compared with the results of the baseline greenhouse gas inventory prepared for the needs of the low-carbon economy plans adopted by the studied self-governments. This allowed us to determine the share of N2O emissions from agricultural soils in the total greenhouse gas emissions of the studied communes. The annual N2O emissions from agricultural soils in the studied communes range from 1.21 Mg N2O-N to 93.28 Mg N2O-N, and the cultivation of organic soils is its main source. The use of mineral and natural fertilisers, as well as indirect emissions from nitrogen leaching into groundwater and surface waters, are also significant. The results confirm the need to include greenhouse gas emissions from the use of agricultural soils and other agricultural sources in low-carbon economy plans.

Low-carbon economy is one of the main trends of economic development at this stage, which emphasizes low energy consumption, low pollution, low emissions and high efficiency and effectiveness. The development of low-carbon economy pays more and more attention to the control of greenhouse gas emissions, so in practice, the construction and utilization of economic development model based on greenhouse gas emission control objectives has outstanding practical value. Carbon finance is a financial model that can effectively control greenhouse gas emissions based on the general background of low-carbon economy, and its influence is expanding in the process of worldwide low-carbon economic development. It is of outstanding practical significance to emphasize the choice of carbon finance development path in the context of low-carbon economy and to realize the standardization and specialization of carbon finance development. The article analyzes and discusses the path choice of carbon finance development under the background of low carbon economy, aiming to provide guidance and help for practical work.

AbstractGreenhouse gas (GHG) emissions from rivers and lakes have been shown to significantly contribute to global carbon and nitrogen cycling. In spatiotemporal-variable and human-impacted rivers in the grassland region, simultaneous carbon dioxide, methane and nitrous oxide emissions and their relationships under the different land use types are poorly documented. This research estimated greenhouse gas (CO2, CH4, N2O) emissions in the Xilin River of Inner Mongolia of China using direct measurements from 18 field campaigns under seven land use type (such as swamp, sand land, grassland, pond, reservoir, lake, waste water) conducted in 2018. The results showed that CO2 emissions were higher in June and August, mainly affected by pH and DO. Emissions of CH4 and N2O were higher in October, which were influenced by TN and TP. According to global warming potential, CO2 emissions accounted for 63.35% of the three GHG emissions, and CH4 and N2O emissions accounted for 35.98% and 0.66% in the Xilin river, respectively. Under the influence of different degrees of human-impact, the amount of CO2 emissions in the sand land type was very high, however, CH4 emissions and N2O emissions were very high in the artificial pond and the wastewater, respectively. For natural river, the greenhouse gas emissions from the reservoir and sand land were both low. The Xilin river was observed to be a source of carbon dioxide and methane, and the lake was a sink for nitrous oxide.

As a part of its obligations under the Climate Convention, the Czech Republic must annually estimate and report its anthropogenic emissions of greenhouse gases. This also applies for the sector of agriculture, which is one of the greatest producers of methane and nitrous oxide emissions. This paper presents the approaches applied to estimate emissions in agricultural sector during the period 1990–2006. It describes the origin and sources of emissions, applied methodology, parameters and emission estimates for the sector of agriculture in the country. The total greenhouse gas emissions reached 7644 Gg CO<sub>2</sub> eq. in 2006. About 59% (4479 Gg CO<sub>2</sub> eq.) of these emissions has originated from agricultural soils. This quantity ranks agriculture as the third largest sector in the Czech Republic representing 5.3% of the total greenhouse gas emissions (GHG). The emissions under the Czech conditions consist mainly of emissions from enteric fermentation, manure management and agricultural soils. During the period 1990–2006, GHG emissions from agriculture decreased by 50%, which was linked to reduced cattle population and amount of applied fertilizers. The study concludes that the GHG emissions in the sector of agriculture remain significant and their proper assessment is required for sound climate change adaptation and mitigation policies.

The negative impact of agricultural production on the environment is manifested, above all, in the emission of greenhouse gases (GHG). The goals of this study were to estimate methane and nitrous oxide emissions at the level of individual farms and indicate differences in emissions depending on the type of production, and to investigate dependencies between greenhouse gas emissions and economic indicators. Methane and nitrous oxide emissions were estimated at three types of farms in Poland, based on FADN data: field crops, milk, and mixed. Data were from 2004–2018. Statistical analysis confirmed the relationship between greenhouse gas emissions and economic performance. On milk farms, the value of methane and nitrous oxide emissions increased with increased net value added and farm income. Milk farms reached the highest land productivity and the highest level of income per 1 ha of farmland. On field crops farms, the relationship between net value added and farm income and methane and nitrous oxide emissions was negative. Animals remain a strong determinant of methane and nitrous oxide emissions, and the emissions at milk farms were the highest. On mixed farms, emissions result from intensive livestock and crop production. In farms of the field crops type, emissions were the lowest and mainly concerned crops.

Nitrous oxide (N2O) from excreta deposited by grazing ruminants is a major source of greenhouse gas emissions in Australia. Experiments to measure N2O emissions from dairy cow dung, urine and pond sludge applied to pasture, and the effectiveness of the nitrification inhibitor nitrapyrin in reducing these emissions, were conducted in south-western Victoria, Australia. In Experiment 1, emissions from urine, with and without nitrapyrin, and from dung were measured. Treatments applied in September 2013 resulted in cumulative emissions (245 days) of 0.60, 5.35, 4.15 and 1.02 kg N2O-nitrogen (N)/ha for the nil, urine (1000 kg N/ha), urine (1000 kg N/ha) + nitrapyrin (1 kg active ingredients/ha), and dung (448 kg N/ha) treatments, respectively, giving emission factors of 0.47% and 0.09% for urine and dung respectively. Nitrapyrin reduced N2O emissions from urine for 35 days, with an overall reduction in emissions of 25%. In Experiment 2, sludge, with and without nitrapyrin, was applied in May 2014, and dung was applied in May, August, November 2014 and January 2015. Cumulative emissions (350 days) were 0.19, 0.49, 0.31 and 0.39 kg N2O-N/ha for the nil, sludge (308 kg N/ha), sludge (308 kg N/ha) + nitrapyrin (1 kg active ingredients/ha), and dung (total 604 kg N/ha) treatments, respectively, giving emission factors of 0.10% and 0.03% for sludge and dung. Nitrapyrin reduced N2O emissions from sludge for 60 days, with an overall reduction in emissions of 59%. A third experiment on two soil types compared emissions from urine and dung, with and without nitrapyrin, applied in different seasons of the year. Emissions were highly seasonal and strongly related to soil water status. Emission factors (90 days) ranged from 0.02% to 0.19% for urine and 0.01% to 0.12% for dung. Nitrapyrin reduced emissions from urine by 0–35% and had little effect on emissions from dung. Overall, the experiments found that nitrapyrin was an effective tool in reducing emissions from urine, dung and sludge applied to pasture, but the magnitude varied across the year, with nitrapyrin being most effective when soils had >70% water-filled pore space when major emissions occurred.

Fertilizers are an important tool to maintain soil fertility and as an enhancement for the efficient crop production. The system of fertilizers application affects the final dose and commonly causes local overdosing or insuficient spatial distribution of fertilizers which are a very important source of nitrous oxide emissions (N2O) from the soil into the atmospher observation of such phenomenon are among the key factors defining environmental impacts of agriculture. A study was conducted to observe the effect of application dose of fertilizer on N2O emission from the soil. CAN (Calcium ammonium nitrate – consist of 27 % nitrogen) was spread by a fertiliser spreader Kuhn Axera 1102 H-EMC aggregated with a tractor John Deere 6150 M. Incorporation of fertilizer into the soil was done by power harrow Pöttinger Lion 302. The application dose was set at 0, 100, 200 and 300 kg.ha–1 while monitoring points were selected at the base of this application doses in respective places. Measurements were conducted at time intervals 7, 14, 21 and 28 days after fertiliser application and following incorporation. Nitrous oxide emissions were measured by field gas monitor set INNOVA consisting of a photoacoustic gas monitor INNOVA 1412 and a multipoint sampler INNOVA 1309. Statistically significant differences was found among time intervals and among the application dose (p > 0.05). It was observed that the application dose of selected fertilizers has the direct effect on nitrous oxide (N2O) emissions released from soil into the atmosphere. An increase of greenhouse gas emissions was observed in range from 0.83 to 152.33 %. It can be concluded that the local overdose of fertilizers negatively affects environmental impact of agricultural practices at greenhouse gas emissions (GHGs).

As part of the nationally determined contribution to the implementation of the Paris Agreement on Climate Change, Mongolia aimsto reduce greenhouse gas emissions (GHGs) by 2.7% by 2030. The country’s per capita of greenhouse gas emissions are 2.7 times higher than the world average and relatively high in the region, and this is becoming a major issue. This is due to the fact that coal alone accounts for more than 90% of primary energy production, whereas renewable energy accounts for a smallproportion of total energy sources. Therefore, the role of the energy sector that emits the most greenhouse gas is important in reducing its fossil fuel consumption.This study addresses the key issues facing Mongolia’s energy sector in reducing greenhouse gas emissions and identifies opportunities for further actions. Furthermore, this will contribute to other studies on sustainable development, transition to a low-carbon economy, and implementation of energy policy recommendations.   Монгол орны уур амьсгалын өөрчлөлтийг сааруулах боломж, тулгарч буй сорилт (Эрчим хүчний салбарын жишээн дээр) Хураангуй: Уур амьсгалын өөрчлөлтийн тухай Парисын хэлэлцээрийг хэрэгжүүлэх үндэсний хэмжээнд тодорхойлсон хувь нэмрийн (ҮХТХН/ NDC) хүрээнд манай улс хүлэмжийн хийн ялгарлыг (ХХЯ) 2030 он гэхэд 22,7% бууруулахаар зорилт тавин ажиллаж байна.
