Brandt (2012). Altmetric Badge. . Producing, transporting, and refining crude oil into fuels such as gasoline and diesel accounts for ∼15 to 40% of the “well-to-wheels” life-cycle greenhouse gas (GHG) emissions of transport fuels (1). Exploring the variation of GHG emissions from conventional oil production using an engineering-based LCA model. global production with uneven geographical coverage). Global carbon intensity of crude oil production. .47 4.6 Land use GHG emissions for 150 year analysis period from field drilling and development in OPGEE for conventional oil operations [g CO 2 eq./MJ of crude oil produced]. . The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Use, Smithsonian In December 2018, the OPEC and Russia agreed to jointly reduce crude oil production to put a downward pressure on oil prices and limit the global glut. We have previously worked to address the first challenge by developing open-source oil-sector CI modeling tools [OPGEE (7, 8), supplementary materials (SM) 1.1]. James Duffy,2 Adam R. Brandt1,† With technical contributions from: Jingfan Wang1, Sylvia Sleep,3 Diana Pacheco,4 Zainab Dashnadi,3 Andrea Orellana,4,? . Tacoma, WA, September 27th 2012. . These carbon intensity values are based on oil field data from the year 2015. Agreement NNX16AC86A, Is ADS down? American Center for Life Cycle Assessment (ACLCA) LCA XII Conference. In the recently published study “Global carbon intensity of crude oil production" (Masnadi et al, Science) the total petroleum well-to-refinery emissions is estimated to be 1,7 Gt CO2 eq, which is 42 per cent higher than the estimations made by the industry and constitute 5 percent of global total emissions. Yet, while regulations are beginning to address petroleum sector GHG emissions (3-5), and private investors are beginning to consider climate-related risk in oil investments (6), such efforts have generally struggled with methodological and data challenges. First, no single method exists for measuring the carbon intensity (CI) of oils. (or is it just me...), Smithsonian Privacy Astrophysical Observatory. Heather MacLean,4 Joule … Emissions in Fig. Producing, transporting, and refining crude oil into fuels such as gasoline and diesel accounts for ∼15 to 40% of the “well-to-wheels” life-cycle greenhouse gas (GHG) emissions of transport fuels (1).

Second, there is a lack of comprehensive geographically rich datasets that would allow evaluation and monitoring of life-cycle emissions from oils. Carbon Intensity of Crude Oil in Europe 1 the International Energy agency (IEa) predicts that global consumption of crude oil will increase 27% over the next two decades, from 83 million barrels per day (mmbbl/d) in 2009 to 105 mmbbl/d in 2030 (IEa, 2009). For the highest intensity crudes, extraction-to-refining constitutes around 40% of the overall carbon footprint, about 50 grams CO 2 per megajoule. Global carbon intensity of crude oil production Published in: Science, August 2018 DOI: 10.1126/science.aar6859: Pubmed ID: Jacob Englander,1 Scott McNally,1,? . global production with uneven geographical coverage). Better understanding of crude oil GHG emissions can help to quantify the benefits of alternative fuels and identify the most cost-effective opportunities for oil-sector emissions reductions (2). Data from Yeh et al [6]. But these emissions vary significantly with source and type of crude and production methods. Here, we address the second challenge by using these tools to model well-to-refinery CI of all major active oil fields globally—and to identify major drivers of these emissions. 1 can vary substantially over time (9), but time-series data are gen-erally missing on a global basis and so are not explored here. 8. Overview of attention for article published in Science, August 2018. Low Carbon Fuels Standard. . Producing, transporting, and refining crude oil into fuels such as gasoline and diesel accounts for ∼15 to 40% of the “well-to-wheels” life-cycle greenhouse gas (GHG) emissions of transport fuels (1). This compares to only about 5%, or 4 grams of CO 2 per megajoule, for the lowest intensity crudes. .48 . Emissions shown in the first figure can vary substantially over time (9), but time-series data are generally missing on a global basis and so are not explored here. . Mohammad S.
