Finding the Missing Link in Methane Emission Inventories Using Aircraft and Mobile Observations

Methane levels were found outside metropolitan areas in this review by aircraft and mobile measurements, which were not published in February and March 2021. Overall, the average measured methane levels at the Mauna Loa Observatory in Hawaii were 239. 4-33. 3 ppb higher than the monthly average methane levels. In addition, methane concentration hotspots were found to be 190. 2–380. 8 ppb higher than the surrounding areas' concentrations. According to the footprint study of four local methane hotspots, industrial complexes, manufacturing waste dumps, and landfills, elevated methane concentrations tend to be associated with intensive pig farm areas, industrial complexes, industrial waste dumps, and landfills. However, as there were significant methane emission sources that were obscured and therefore out of the methane database, the current estimates of methane emissions may have been mischaracterized. This report reveals that more attention is required to track methane leaks from both unknown and established methane emission sources.

Methane emissions from US low production oil and natural gas well sites

Eighty percent of the U. S. oil and natural gas production sites are poor production well sites, with average daily production of 15 barrels of oil equivalent per day and only 6% of the country's O&G output in 2019. We estimate that low production well sites account for nearly half of all O&G well site CH_4 emissions, with a production-normalized CH_4 loss rate of more than 10%, which is 6—12 times higher than average CH_4 loss rate of 1. 5% for all O&G well sites in the United States. Only 6 percent of U. S. oil and natural gas production output comes from low production well sites, with just 6 percent being from low production well sites. The authors' estimate that total methane emissions from these low-production well sites in the United States are high, totaling about one-half of all production site methane emissions.

Impact of a methane emission tax on circular economy scenarios in small wastewater treatment plants

This paper examines the effect of methane pollution taxation on the revival of the installations that use biogas energy in small wastewater treatment plants in Brazil. It is based on the assumption that the introduction of a national methane emission tax policy would encourage small WWTPs to become profitable power plants. The circular economy can support the expansion of the wastewater collection and treatment scheme, as well as providing widespread sanitation services in urban areas. However, the successful implementation of a methane emission levy in Brazil needs multiple rounds of dialogue among sanitation companies, government, and civil society to establish emission limits, and unit taxes, as well as to safeguard a carbon trade following the same decision in the sanitation industry.

Bovine host genome acts on rumen microbiome function linked to methane emissions

The microbiome is under host genomic control, with 1,107/1,141 rumen microbial genera/genes isolated from complete metagenomics sequencing, 194/14/337 having significant host genomic modifications, revealing that significant variation of the microbiome is under host genomic control. The high possibility of microbiome-driven breeding in our population has consistently reduced CH_4 emissions and mitigate climate change, with a selection based on abundances of the 30 most common microbial genes providing a mitigation potential of 17% of mean CH_4 emissions per generation, which is higher than that based on measured CH_4 emissions per year and mitigation.
