Air Emissions of Ammonia and Methane from Livestock Operations: Valuation and Policy Options AgEcon
Shih, Jhih-Shyang; Burtraw, Dallas; Palmer, Karen L.; Siikamaki, Juha.
The animal husbandry industry is a major emitter of methane, which is an important greenhouse gas. The industry is also a major emitter of ammonia, which is a precursor of fine particulate matter, arguably the number-one environment-related public health threat facing the nation. We present an integrated process model of the engineering economics of technologies to reduce methane and ammonia emissions at dairy operations in California. Three policy options are explored: greenhouse gas offset credits for methane control, particulate matter offset credits for ammonia control, and expanded net metering policies to provide revenue for the sale of electricity generated from captured methane gas. Individually, any of these policies appears to be sufficient to...

Allocation of CO2 Emissions Allowances in the Regional Greenhouse Gas Cap-and-Trade Program AgEcon
Burtraw, Dallas; Palmer, Karen L.; Kahn, Danny.
Cap-and-trade programs for air emissions have become the widely accepted, preferred approach to cost-effective pollution reduction. One of the important design questions in a trading program is how to initially distribute the emissions allowances. Under the Acid Rain program created by Title IV of the Clean Air Act, most emissions allowances were distributed to current emitters on the basis of a historic measure of electricity generation in an approach known as grandfathering. Recent proposals have suggested two alternative approaches: allocation according to a formula that is updated over time according to some performance metric in a recent year (the share of electricity generation or something else) and auctioning allowances to the highest bidders....

An Experimental Analysis of Auctioning Emission Allowances Under a Loose Cap AgEcon
Shobe, William; Palmer, Karen L.; Myers, Erica; Holt, Charles; Goeree, Jacob K.; Burtraw, Dallas.
The direct sale of emission allowances by auction is an emerging characteristic of cap-and-trade programs. This study is motivated by the observation that all of the major implementations of cap-and-trade regulations for the control of air pollution have started with a generous allocation of allowances relative to recent emissions history, a situation we refer to as a “loose cap.” Typically more stringent reductions are achieved in subsequent years of a program. We use an experimental setting to investigate the effects of a loose cap environment on a variety of auction types. We find that all auction formats studied are efficient in allocating emission allowances, but auction revenues tend to be lower relative to competitive benchmarks when the cap is...

Analyzing Large Paleoclimate Datasets: Implications for Past and Future Climate Change. ArchiMer
Shakun, Jeremy D.
This dissertation presents the results of statistical analyses of large climate datasets from two time intervals – the 20th century instrumental record and the proxy record of the last deglaciation – in order to understand the forcings and mechanisms of past climate variability. A longstanding question in climate dynamics concerns the origin of Pacific decadal variability (PDV). This issue is addressed by calculating the Southern Hemisphere equivalent of the Pacific Decadal Oscillation (PDO) index from Pacific sea surface temperature (SST) anomalies over the 20th century, which is found to be similar to its Northern Hemisphere counterpart. The Northern and Southern PDO indices both exhibit pronounced seasonality in autocorrelation with interannual...

Are there Carbon Savings from US Biofuel Policies? Accounting for Leakage in Land and Fuel Markets AgEcon
Bento, Antonio M.; Klotz, Richard; Landry, Joel R..
This paper applies the insights of the carbon leakage literature to study the emissions consequences of biofuel policies. We develop a simple analytic framework to decompose the intended emissions impacts of biofuel policy from four sources of carbon leakage: domestic fuel markets, domestic land markets, world land markets and world crude oil markets. A numerical simulation model illustrates the magnitude of each source of leakage for combinations of two current US biofuel policies: the Volumetric Ethanol Excise Tax Credit (VEETC) and the Renewable Fuel Standard (RFS). In the presence of both land and fuel market leakage, current US biofuel policies are unlikely to reduce greenhouse gases. Four of the five policy scenarios we consider lead to increases in...

Attractants for automated emission measurement (Greenfeed®) in pasture-based systems. Repositório Alice
MOMBACH, M. A.; CARVALHO, P. de; CABRAL, L. da S.; RODRIGUES, R. de A. R.; TORRES, R. C.; PEREIRA, D. H.; PEDREIRA, B. C. e.
This study aimed to evaluate the frequency and intensity of GreenFeed (GF) use by Nellore steers using different attractants in pastures of integrated systems. The attractant protein supplement and Tifton bermudagrass pelleted hay flavored with vanilla were evaluated over a period of 15 days. The pelleted hay stimulated the animals to stay longer in the equipment (24.23 s), with 8% more visits in intervals longer than 30 s in contrast to protein supplement. This indicates that pelleted hay flavored with vanilla is a potential attractant to encourage Nellore steers to visit GF in grazing systems.

Auctioning Greenhouse Gas Emissions Permits in Australia AgEcon
Betz, Regina; Seifert, Stefan; Cramton, Peter; Kerr, Suzi.
Allocating permits based on individual historical emissions (‘grandfathering’), or industry benchmark data, is an important design aspect of an emissions trading scheme. Free permit allocation has proven complex and inefficient (particularly in the European Union) with distribution implications also politically difficult to justify. For these reasons, auctioning emissions permits has become more popular than allocating permits. The European Union is now moving towards auctioning more than 50 per cent of all permits in 2013. In the US, the Regional Greenhouse Gas Initiative (RGGI) has started with auctioning 100 per cent of permits. The Australian proposal for a Carbon Pollution Reduction Scheme (CPRS) also provides for auctioning a significant share of...

FASIABEN, M. do C. R.; MAIA, A. G.; BARIONI, L. G.; LAZOU, J..
O presente trabalho trata da relevância de ações de enfrentamento das condicionantes ambientais ligadas à pecuária brasileira, como forma de alavancar seu crescimento com o mínimo de danos ao meio ambiente. O indicador ambiental Pegada Ecológica (PE) expressa a pressão do consumo humano sobre o meio ambiente, no Brasil e no mundo. A partir de dados internacionais da Global Footprints Network procedeu-se ao agrupamento de países segundo a participação de cada um dos principais componentes que integram a PE. Cinco grupos foram encontrados, estando o Brasil enquadrado naquele que se caracteriza pela predominância de uma bovinocultura extensiva em pastagens e, relativamente, baixo consumo de energia fóssil (grupo 3). No caso brasileiro, o componente...

Biochar and soil nitrous oxide emissions. Repositório Alice
ALHO, C. F. B. V..; CARDOSO, A. da S.; ALVES, B. J. R.; NOVOTNY, E. H..
The objective of this work was to evaluate the effect of biochar application on soil nitrous oxide emissions. The experiment was carried out in pots under greenhouse conditions. Four levels of ground commercial charcoal of 2 mm (biochar) were evaluated in a sandy Albaqualf (90% of sand): 0, 3, 6, and 9 Mg ha‑1. All treatments received 100 kg ha‑1 of N as urea. A cubic effect of biochar levels was observed on the N2O emissions. Biochar doses above 5 Mg ha‑1 started to mitigate the emissions in the evaluated soil. However, lower doses promote the emissions.

Biochar (carbonized biomass for agricultural use) has been used worldwide as soil amendment and is a technology of particular interest for Brazil, since its ?inspiration? is from the historical Terra Preta de Índios (Amazon Dark Earth), and also because Brazil is the world?s largest charcoal producer, generating enormous residue quantities in form of fine charcoal and due to the availability of different residual biomasses, mainly from agroindustry (e.g., sugar-cane bagasse; wood and paper-mill wastes; residues from biofuel industries; sewage sludge etc), that can be used for biochar production, making Brazil a key actor in the international scenario in terms of biochar research and utilization). In the last decade, numerous studies on biochar have been...

This paper evaluated the municipal performance of beef cattle production systems in 2006 and 2017, in relation to the enteric methane emissions in CO2 equivalent. The 109 municipalities evaluated belong to the Cerrado biome of the Maranhao state,Brazil. In this period the cattle population increased 20% and reached 3.3 million head; the pasture area remained at 2.6 million hectares. The total enteric methane emission, computed by the Agriculture and Land Use National Greenhouse Gas Inventory Software (ALU), was 3,867 Gg of CO2eq in 2006 and 4,654 Gg of CO2eq in 2017. The municipalities with higher cattle numbers were classified as ?Regions of net CO2 sink?. The performance score was calculated considering the pasture and forest area, herd size, enteric...

Chamber measurement methods and aeration effect on greenhouse gas fluxes during composting CIGR Journal
Park, Kyu-Hyun; Ngwabie, Ngwa Martin; Wagner-Riddle, Claudia.
Composting has the potential to mitigate methane (CH4) and nitrous oxide (N2O) emissions from manure.  The heterogeneous nature of emitting surfaces makes it difficult to quantify these emissions.  CH4 and N2O fluxes measured using eight small chambers (0.72 m2) and a mega chamber (90 m2) were compared, and the effect of aeration on the fluxes during composting was studied.  Two batches of compost were placed in three channels and 2-3 small flux chambers were deployed on each channel.  The channels were enclosed by a building serving as a mega chamber.  Chamber location significantly affected gas fluxes, pointing to strong spatial heterogeneity.  Mean CH4 fluxes from the small chambers were similar or 1.4 times higher compared to the mega chamber.  Mean...

Climate Change Policy and the Adoption of Methane Digesters on Livestock Operations AgEcon
Key, Nigel D.; Sneeringer, Stacy E..
Methane digesters—biogas recovery systems that use methane from manure to generate electricity—have not been widely adopted in the United States because costs have exceeded benefits to operators. Burning methane in a digester reduces greenhouse gas emissions from manure management. A policy or program that pays producers for these emission reductions—through a carbon offset market or directly with payments—could increase the number of livestock producers who would profit from adopting a methane digester. We developed an economic model that illustrates how dairy and hog operation size, location, and manure management methods, along with electricity and carbon prices, could influence methane digester profits. The model shows that a relatively moderate...

We present the global general circulation model IPSL-CM5 developed to study the long-term response of the climate system to natural and anthropogenic forcings as part of the 5th Phase of the Coupled Model Intercomparison Project (CMIP5). This model includes an interactive carbon cycle, a representation of tropospheric and stratospheric chemistry, and a comprehensive representation of aerosols. As it represents the principal dynamical, physical, and bio-geochemical processes relevant to the climate system, it may be referred to as an Earth System Model. However, the IPSL-CM5 model may be used in a multitude of configurations associated with different boundary conditions and with a range of complexities in terms of processes and interactions.

CO2 Allowance Allocation in the Regional Greenhouse Gas Initiative and the Effect on Electricity Investors AgEcon
Burtraw, Dallas; Kahn, Danny; Palmer, Karen L..
The Regional Greenhouse Gas Initiative (RGGI) is an effort by nine Northeast and Mid-Atlantic states to develop a regional, mandatory, market-based cap-and-trade program to reduce greenhouse gas (GHG) emissions from the electricity sector. The initiative is expected to lead to an increase in the price of electricity in the RGGI region and beyond. The implications of these changes for the value of electricity-generating assets and the market value of the firms that own them depends on the initial allocation of carbon dioxide allowances, the composition of generating assets owned by the firm, and the locations of those assets. Changes in asset values inside the RGGI region may be positive or negative, whereas changes outside of the RGGI region are almost...

CO2 and N2O emissions from an Andisol in Chile under a no-till system using non-fixed closed chambers Chilean J. Agric. Res.
Muñoz,Cristina; Paulino,Leandro; Vera,Jenniffer; Zagal,Erick.
Chile has different types of soil and climate conditions that favor a wide range of agricultural activities that can generate potential atmospheric contamination like greenhouse gases (GHG). Nevertheless, the contribution of agricultural soils to atmospheric emissions has yet to be measured in Chile. The aim of this study was to assess seasonal variability of CO2 and N2O effluxes in situ from a volcanic ash-derived soil under different agronomic management practices. Gas samples were obtained from headspaces of non-fixed closed chambers in an annual crop rotation under a no-till system in an Andisol in southern Chile (36° S). Two N-sources (NH4+ and NO3-) and ammonium fertilization plus two lime doses (0.5 and 1 Mg ha-1) were considered for soil treatments...
