Recent advances in fossil fuel CO2 (FFCO2) emission inventories enable sensitivity tests of simulated atmospheric CO2 concentrations to sub-annual variations in FFCO2 emissions and what this implies for the interpretation of observed CO2. Six experiments are conducted to investigate the potential impact of three cycles of FFCO2 emission variability (diurnal, weekly and monthly) using a global t...

The potential use of satellite observed nighttime lights for estimating carbondioxide (CO2) emissions has been demonstrated in several previous studies. However, the procedures for a moderate resolution (1 km 2 grid cells) global map of fossil fuel CO2 emissions based on nighttime lights are still in the developmental phase. We report on the development of a method for mapping distributed (excl...

I never thought I’d favor nuclear power. But here it is: I believe nuclear energy is our last best chance to stem the tide of climate change. Time is running out for reversing greenhouse gas emissions and transitioning from the fossil fuel age. Nuclear power must occupy a larger share of our energy mix and replace coal-fired power plants. For energy policy, I think “near-term” decisions should ...

As a less-developed province that has been chosen to be part of a low-carbon pilot project, Yunnan faces the challenge of maintaining rapid economic growth while reducing CO2 emissions. Understanding the drivers behind CO2 emission changes can help decouple economic growth from CO2 emissions. However, previous studies on the drivers of CO2 emissions in less-developed regions that focus on both ...

this study investigated different concepts for natural-gas-fired power plants with the co2capture, and compared them based on the net plant efficiency and emission of co2. the cycles were based ona six oxy-fuel, one post-combustion and two pre-combustion capture concept. this paper presented theresults of an environmental evaluation performed by the application of the life cycle analysis (lca) ...

China’s CO2 emissions have sharply increased in recent years with soaring economic development and urbanization. Consumption-based accounting of CO2 emissions could provide new insights for allocating regional mitigation responsibility and curbing the emissions. A multi-regional input–output model is used to study the trends and disparities of consumption-based emissions from Chinese provinces ...

This paper is aimed at improving the maintenance and end-of-life steps in associated Life Cycle Assessment (LCA) of barge-type floating wind turbines to reduce their environmental impact. Maintenance are given special attention since these phases have received only cursory focus previous LCA studies. Different scenarios been considered analysis. From results, it has found that by applying on-si...

Crop diversification is essential in lowland rice cropping systems to achieve sustainability, improve soil health, and as a climate-resilient practice reduce greenhouse gas (GHG) emissions. A life cycle assessment (LCA) was conducted for the farms west-coast region of India assess environmental impact rice–rice rice–cowpea systems. The (LCIA) evaluated “cradle-to-gate” perspective. higher energ...

Ghana is an important cocoa producer and exporter this production of high economic importance. Increasing interest in the sustainable productions cocoa/chocolate necessitated need to assess environmental impacts associated with different chocolate variants (extra dark (EDC), (DC), milk (MC) flavoured (FMC) Ghana, including identification hotspots for improvement. The life cycle assessment tool ...
