“…An engineering-based analysis considering the heterogeneity of individual fields is required to identify underlying drivers of the variability of emissions. The analysis of GHG emissions of natural gas supplies to China at such a granular level has not been done before and will provide insights into emission reductions and clean energy policymaking [24][25][26] .…”

As natural gas demand surges in China, driven by the coal-to-gas switching policy, widespread attention is focused on its impacts on global gas supply-demand rebalance and greenhouse gas (GHG) emissions. Here, for the first time, we estimate well-to-city-gate GHG emissions of gas supplies for China, based on analyses of field-specific characteristics of 104 fields in 15 countries. Results show GHG intensities of supplies from 104 fields vary from 6.2 to 43.3 g CO 2 eq MJ −1 . Due to the increase of GHG-intensive gas supplies from Russia, Central Asia, and domestic shale gas fields, the supply-energy-weighted average GHG intensity is projected to increase from 21.7 in 2016 to 23.3 CO 2 eq MJ −1 in 2030, and total well-to-city-gate emissions of gas supplies are estimated to grow by~3 times. While securing gas supply is a top priority for the Chinese government, decreasing GHG intensity should be considered in meeting its commitment to emission reductions.

“…A recent study estimating the global carbon intensity of crude oil assessed the total well‐to‐refinery emissions at 1.7 Gt CO 2 equivalents, recording an increase of 42% from the previous estimations made by the industry. The well‐to‐refinery emissions represent 5% of the global total emissions, and to draw a comparison the global emissions from aviation is nearly 2.7%.…”

The concentration of greenhouse gases (GHG)s and specifically CO2 continue to rise in the global environment including the atmosphere and the oceans. Oil and gas exploration in oceans and the increased probability of CO2 being destined for ocean storage have made the oceans much vulnerable to acidification and hence detrimental to the entire marine ecosystem. Offshore wind energy, along with other renewables, have the potential to lower the rate of CO2 absorption in the global eco system. Distant offshore wind farms are faced with the problem of dispatch of surplus wind power. Power‐to‐gas technology can be used to convert the offshore wind power into synthetic natural gas that can be transported through the existing network of offshore gas pipelines. The novel method has the capability to significantly reduce GHG emissions, solve the power dispatch problems of offshore wind farms, as well as reduce the oceanic environmental degradation. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd.

“…Flaring of natural gas is an important contributor to the greenhouse gas (GHG) impacts of upstream oil production operations. In a global synthesis of field-level oil climate intensity (Masnadi et al 2018), a large number of global oil fields with emissions intensity in the top quartile were found to be exhibiting high flaring rates. This presents a climate mitigation opportunity, as flaring is a problem with technical and market solutions (Elvidge et al 2018).…”

Flaring of natural gas contributes to climate change and wastes a potentially valuable energy resource. Various groups have estimated flaring volumes via remote sensing by nighttime detection of flares using multi-spectral imaging. However, only limited efforts have been made to independently assess the accuracy of these estimation methods. I analyze the accuracy of the VIIRS Nightfire published flare detection results, comparing yearly estimated flaring rates to reported flaring data from governments in 9 countries (Brazil, Canada, Denmark, Mexico, Netherlands, Nigeria, Norway, USA, UK) and 7 years (2012-2018 inclusive). We analyze only flares occurring at offshore oil and gas production platforms and floating production units. A total of 1054 flare volume estimates were compared to volumes reported to government agencies. 80.8% of flare estimates lie within 0.5 orders of magnitude (OM) of reported volumes, which 93.7% fall within 1 OM of the reported volume. Little systematic bias is found except in the smallest size classes (<10 6 m 3 y −1 ). Relative error ratios are larger for smaller flares. No significant trend was observed across years, and variation by country is in line with that expected by size distribution of flares by country. Wide aggregate estimates for groups of flares will exhibit little bias and dispersion, with the sum of 1000 flares having an expected interquartile range of −6% to +3% of actual reported volumes. Social media blurb: Test of remote sensing for flare detection shows accuracy across 9 countries and 8 years.
