A novel approach to rapidly tracking whole-farm methane emissions
Enteric fermentation and manure from livestock farming are major sources of methane (CH 4 ) emissions and have a large potential for emissions reduction. However, there is a lack of effective methods for evaluating future emissions reduction efforts, especially at the farm scale. We developed a rapid analysis method to evaluate CH 4 emissions from a large number of dairy cow farms in the Netherlands based on single-transect mobile van measurement…
CH4 isotopic signatures of emissions from oil and gas extraction sites in Romania
Methane (CH4) emissions to the atmosphere from the oil and gas sector in Romania remain highly uncertain despite their relevance for the European Union’s goals to reduce greenhouse gas emissions. Measurements of CH4 isotopic composition can be used for source attribution, which is important in top-down studies of emissions from extended areas. We performed isotope measurements of CH4 in atmospheric air samples collected from an aircraft (24 locat…
Methane and ethane emission quantifications from onshore oil and gas sites in Romania, using a tracer gas dispersion method
Site-specific methane (CH4) and ethane (C2H6) emission rates from the onshore oil and gas (O&G) sector in Romania were quantified, using the mobile tracer gas dispersion method. As part of the coordinated Romanian Methane Emission from Oil & Gas measurement campaign, this study supported the investigation of CH4 emissions from the O&G sector around Bucharest. CH4 emission rates measured at 200 O&G sites were highly skewed with a heavy tail and de…
Low cost and state of the art methods to measure nitrous oxide emissions
This letter provides an overview of the available measurement techniques for nitrous oxide (N2O) \nflux measurement. It is presented to aid the choice of the most appropriate methods for different \nsituations. Nitrous oxide is a very potent greenhouse gas; the effect of 1 kg of N2O is estimated to \nbe equivalent to 300 kg of CO2. Emissions of N2O from the soil have a larger uncertainty \ncompared to other greenhouse gases. Important reasons for…
NitroGenius
A nitrogen decision support system in the form of a game (NitroGenius) was developed for the Second International Nitrogen Conference. The aims were to: i) improve understanding among scientists and policy makers about the complexity of nitrogen pollution problems in an area of intensive agricultural, industrial, and transportation activity (The Netherlands); and ii) search for optimal policy solutions to prevent pollution effects at lowest econo…
