Agriculture and climate change: The role of nutrient management in mitigation por Flynn, Helen C.

“…Nitrous oxide (N2O) emissions from soils are responsible for about 3 percent of greenhouse gas (GHG) emissions, which cause climate change, and contribute approximately one-third of non-CO2 agricultural GHG emissions. …”

Kostnadseffektiv svaveldioxidreduktion por Karlsson, Linda

“…From a strictly Swedish perspective it would instead be optimal with an international agreement where the target is to reduce deposition of sulphur dioxide in Sweden. The aim with this thesis is to compare two cost efficient reductions of sulphur dioxide; one where the target is to reduce the international emissions and the other one where the target is to reduce the deposition in Sweden. …”

Improved methods for carbon accounting for bioenergy: descriptions and evaluations por Pena, N., Bird, D.N., Zanchi, G.

“…Fourth, a Type 3 approach supports greenhouse gas emission reductions and preservation of forests but is less simple, and stimulation of the rural economy depends on the structure of the cap-and-trade system.…”

Nitrous oxide and methane fluxes from urine and dung deposited on Kenyan pastures por Tully, Katherine L., Abwanda, Sheila O., Thiong'o, Margaret, Mutuo, Paul M., Rosenstock, Todd S.

“…However, the relationship was linear during the dry season (r2 = 0.99; P = 0.001) and exponential during the wet season (r2 = 0.99; P < 0.0001). Nitrous oxide emission factors were 0.05% (dry season) and 0.18% (wet season) of N in urine and dung+urine, which is less than 10% of the IPCC Default Tier 1 emission factor of 2%. …”

Benefits and tradeoffs of reduced tillage and manure application methods in a Zea mays silage system por Dittmer, Kyle M, Darby, Heather M., Goeschel, Tyler R, Adair, E. Carol

“…A critical question is whether there are agricultural management practices that can attain the multiple management goals of increasing yields, preventing nutrient losses, and suppressing greenhouse gas (GHG) emissions. No‐till and manure application methods, such as manure injection, can enhance nutrient retention, but both may also enhance emissions of nitrous oxide (N2O), a powerful GHG. …”

How can African agriculture adapt to climate change: Global carbon markets: Are there opportunities for Sub-Saharan Africa? por Bryan, Elizabeth, Akpalu, Wisdom, Ringler, Claudia, Yesuf, Mahmud

“…Carbon trading includes allowance-based agreements that impose national caps on emissions and allow participating countries to engage in emission trading as well as project-based transactions (for example, through the CDM or Clean Development Mechanism). …”

Utvärdering av koldioxidmätaren Vaisala GMP343 samt sambandet mellan grundvattennivå och koldioxidavgång från torvjordar por Öhrlund, Isak

“…The research group Soil and Water Management at the department of Soil and Environment at the Swedish University of Agricultural Sciences in Uppsala are studying greenhouse gas emissions from cultivated peat soils. To measure carbon dioxide emissions from peat soils in the field the research group are now using two portable carbon dioxide meters (Vaisala GMP343). …”

Kaffesump som substrat i biogasanläggningar eller som bränsle i fjärrvärmeverk : en studie av effekter på växthusgasutsläpp och kostnader por Fors, Erik

“…Transporting coffee waste from Ericsson to different biogas plants will result in increased carbon dioxide emissions. The three plants investigated in this thesis are Henriksdals sewage treatment plant, the Himmerfjärd plant and Uppsala biogas plant. …”

Kan mjölkkors utnyttjande av vallprotein bli bättre? : utfodringsstrategier och konserveringsmetoder por Pettersson, Emma

“…Studies have also shown that proteins in red clover silage are more preserved than in alfalfa silage because less proteolysis occurs in red clover. When the forage contains excessive amounts of non protein nitrogen and the energy source is insufficient, the microbes can't synthesize microbial proteins and the excess of nitrogen will be excreted as urea in the urine. …”

Assessment of food retail business sustainability : the case of Konsum Värmland por Bekele, Addis

“…Especially, further study based on detailed quantitative data on emission, waste generation, and efficiency of utilization of resources such as energy, water, paper, vehicles and other resources is necessary. …”

Handel med utsläppsrätter por Arvidsson, Anna, Larsson, Maria

“…The Kyoto Protocol is an agreement between a number of industrialized countries to limit or reduce the green gas emissions. The European Union has decided to introduce a system for tradable permits for carbon dioxide from year 2005 to reduce emissions and get experience in emission trade. …”

Växthusgasutsläpp vid sandinblandning i torvjordar por Mattsson, Andreas

“…Growing crops in these soils require drainage which speeds up the degradation of the organic matter and increases the greenhouse gas emissions. Cultivated organic soils are responsible for 6-8 % of the total amount of anthropogenic greenhouse gas emissions in Sweden. …”
