Greenhouse gas impact of bioenergy pathways

This study, commissioned by the International Renewable Energy Agency (IRENA), offers an assessment of the effect of bioenergy on greenhouse gas emissions. It combines estimates of supply-chain emissions from liquid and solid biofuels and direct and indirect land-use-change emissions with different bioenergy pathways: for transport fuel, electricity, and heat. The …

India to go directly to Euro-VI fuel standards: Pradhan

In a bid to curb vehicular pollution, India will go straight from Euro-IV complaint petrol and diesel to Euro-VI fuel by 2020, Oil Minister Dharmendra Pradhan said on Thursday. “We are not going for Bharat Stage V (or Euro—V) petrol and diesel as there is not much difference between BS—V …

'Switch to CNG bus, cut per capita PM emission'

If you have a BS IV-compliant diesel car and usually ride alone, you can reduce your per capita particulate (PM) emissions per kilometre by at least 40 times by using a CNG bus instead. And if you have been driving a diesel SUV, then the benefit could be to the …

Environmental watchdog puts polluting products on blacklist

In a recent effort to promote green development, China's environmental watchdog put more than 400 types of polluting products on a blacklist. The move means the export of these products will not be entitled to tax refunds and the processing trade will be banned, reported thepaper.cn. The Comprehensive List of …

Putting a price on carbon: reducing emissions

The United States will need new legislation to achieve its long-term target of reducing greenhouse gas (GHG) emissions by more than 80 percent by 2050. In this issue brief, show how a national carbon price—in the form of either a carbon tax or a cap-and-trade program—can help the United States …

Storing CO2 through enhanced oil recovery

Carbon dioxide (CO2) has been used in commercial manner for decades to increase recovery from oil fields in a process called "CO2-enhanced oil recovery" or CO2-EOR. Harnessing this practice to qualify as permanent storage of CO2 is possible, but requires a major paradigm shift from conventional EOR to "EOR+", including …

Biogas and household air quality: study on household air quality and estimated health improvement of users of biogas stoves versus wood-fired stoves in rural Cambodia

The potential for domestic biogas is enormous in Cambodia with 1 million households that have sufficient livestock to feed for the smallest biogas digester. Biogas could therefore help to address HAP in Cambodia to millions of rural inhabitants. The National Biodigester Programme (NBP) of Cambodia, a partnership between SNV and …

Estimating global warming potential for agricultural landscapes with minimal field data and cost

Greenhouse gas (GHG) emissions from agriculture comprise 10-12% of anthropocentric global emissions; and 76% of the agricultural emissions are generated in the developing world.
