Informing landfill emission reporting programs through remote sensing
Landfills are a significant source of anthropogenic methane emissions. Governments and operators rely on models with process and waste characterization assumptions to quantify emissions, assess management strategies like gas collection systems, and set reduction targets. However, validating these models through atmospheric measurements is difficult given the variability of landfill emissions and the challenge of sampling a diverse range of sites.…
Evaluating the impact of anaerobic digesters on point source methane emissions from California dairies from remote sensing
Dairies are the largest source of methane (CH 4 ) emissions in California, with 57% of statewide emissions attributed to wet manure management systems. California has implemented CH 4 mitigation strategies, including anaerobic digesters (ADs), to capture and convert CH 4 produced by wet manure storage into renewable energy. While ADs are estimated to achieve large reductions in manure CH 4 emissions, studies centered on their performance and the …
Satellite monitoring of annual US landfill methane emissions and trends
We use satellite observations of atmospheric methane from the TROPOMI instrument to estimate total annual methane emissions for 2019–2023 from four large Southeast US landfills with gas collection and control systems. The emissions are on average 6× higher than the values reported by the landfills to the US Greenhouse Gas Reporting Program (GHGRP) which are used by the US Environmental Protection Agency for its national Greenhouse Gas Inventory (…
Not just a climate problem
Methane super-emitter events (>100 kg methane hr −1 ) are prevalent across the oil and gas supply chain and are being targeted for methane mitigation policies due to their climate impacts; however, few studies have evaluated the air quality impacts and direct safety and public health risks. Here, we evaluate seven upstream oil and gas methane super-emitter events to examine the safety (explosivity) risks from methane and the short-term, noncancer…
A declining trend of methane emissions in the Los Angeles basin from 2015 to 2020
The Los Angeles (LA) basin was responsible for approximately 20% of California’s methane emissions in 2016. Hence, curtailment of these emissions is required to meet California’s greenhouse gas emissions reduction targets. However, effective mitigation remains challenging in the presence of diverse methane sources like oil and gas production fields, refineries, landfills, wastewater treatment facilities, and natural gas infrastructure. In this st…
Empirical quantification of methane emission intensity from oil and gas producers in the Permian basin
Methane (CH 4 ) emissions from the oil and natural gas (O&G) supply chain have been demonstrated to be one of the largest anthropogenic greenhouse gas emission sources ripe for mitigation to limit near-term climate warming. In recent years, exploration and production (E&P) operators have made public commitments to reducing their greenhouse gas emission intensity, yet little empirical information has been made available in the public domain to all…
Methane remote sensing and emission quantification of offshore shallow water oil and gas platforms in the Gulf of Mexico
Offshore oil and natural gas platforms are responsible for about 30% of global oil and natural gas production. Despite the large share of global production there are few studies that have directly measured atmospheric methane emanating from these platforms. This study maps CH 4 emissions from shallow water offshore oil and gas platforms with an imaging spectrometer by employing a method to capture the sun glint reflection from the water directly …
Using remote sensing to detect, validate, and quantify methane emissions from California solid waste operations
Solid waste management represents one of the largest anthropogenic methane emission sources. However, precise quantification of landfill and composting emissions remains difficult due to variety of site-specific factors that contribute to landfill gas generation and effective capture. Remote sensing is an avenue to quantify process-level emissions from waste management facilities. The California Methane Survey flew the Next Generation Airborne Vi…
Quantifying the influence of agricultural fires in northwest India on urban air pollution in Delhi, India
Since at least the 1980s, many farmers in northwest India have switched to mechanized combine harvesting to boost efficiency. This harvesting technique leaves abundant crop residue on the fields, which farmers typically burn to prepare their fields for subsequent planting. A key question is to what extent the large quantity of smoke emitted by these fires contributes to the already severe pollution in Delhi and across other parts of the heavily p…
