Abstract. Zero Emissions Commitment (ZEC), the expected change in global temperature following cessation of anthropogenic greenhouse gas emissions, has recently been assessed by Model Intercomparison Project (ZECMIP). ZECMIP concluded that component ZEC from CO2 emissions will likely be close to zero decades emissions. However, 18 Earth system models participated only 2 included a representatio...

Nitrous oxide (N2O) is a potent greenhouse gas (GHG) contributing to global warming, with the agriculture sector as the major source of anthropogenic N2O emissions due to excessive fertilizer use. There is an urgent need to enhance regional/watershedscale models, such as Soil and Water Assessment Tool (SWAT), to credibly simulate N2O emissions to improve assessment of environmental impacts of c...

World first hybrid passenger ferries achieve 50% fuel and CO2 savings 12 month scheduled maintenance agreement>1,280 tonnes per year of CO2 emmissions saved; zero emissions at wharf when in electric mode>8-17% fuel savings Fuel savings approx HK$2.5million per year Replace ageing fleet; 12 month schedule maintenance contract; redundant propulsion system Redundant propulsion system to assist boa...

It has been shown that biomass refinery (biorefinery) with Zero Emissions perspective could convert agricultural wastes into valueadded chemicals and materials. Agricultural and plantations wastes would become as main resources for biorefinery without soil degradation and needs of additional land. Biorefinery non-farm production cycle is crucial for job generation and poverty elimination in rur...

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 ...

In the context of global climate change and various environmental problems, stabilizing average temperature, implementing near zero carbon emissions, finally achieving absolute emissions in future have become an important task China’s ecological civilization construction. As population industrial cluster, park is carrier economic social activities, so most form to achieve dual goal. Based on bl...

The Japanese government has set the goal of achieving net zero GHG emissions by 2050 and aims to reduce 46% from 2013 level 2030 as an interim target. Natural gas is one low carbon fuels with potential emissions, development technology that utilizes natural important achieve this

Greenhouse gas (GHG) emissions per person from urban waste management activities are greater in sub-Saharan African countries than in other developing countries, and increasing as the population becomes more urbanised (Couth and Trois, 2010). Waste from urban areas across Africa is essentially dumped on the ground with little or no control over the relative liquid and gaseous emissions. The Cle...
