Environmental trade-offs of pig production systems under varied operational efficiencies
Production of pork, the most consumed meat globally, is estimated to emit 668 m tonnes CO2-eq of greenhouse gases each year. Amongst various production systems that comprise the pig industry, grain-based intensive production is widely regarded as the largest polluter of the environment, and thus it is imperative to develop alternative systems that can provide the right balance between sustainab...
متن کاملOperational Measures For Energy Efficiency In Shipping
1.Introduction Energy efficiency and environmental performance are mainstream issues for ship operators who are aiming through low carbon shipping and cost reductions. Although reducing fuel consumption seems to have priority, environmental considerations also push the shipping industry to operate in more efficient way. Strict legislations on GHG emissions and increasing fuel prices turn the fo...

15 صفحه اولEnergy use efficiency, GHG emissions, and carbon efficiency of paddy rice production in Iran
The energy efficiency, greenhouse gas (GHG) emissions, and carbon efficiency of paddy rice production were analysed in Sari in the Mazandaran province of Iran during 2011–2012. Data was collected through questionnaires and interviews with paddy producers. The results showed that the net energy gain was 27,932 MJ ha-1 and energy efficiency was 1.83 during production. The results o...
