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.…
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 (…
Attribution of the 2020 surge in atmospheric methane by inverse analysis of Gosat observations
Atmospheric methane mixing ratio rose by 15 ppbv between 2019 and 2020, the fastest growth rate on record. We conduct a global inverse analysis of 2019–2020 Greenhouse Gases Observing Satellite observations of atmospheric methane to analyze the combination of sources and sinks driving this surge. The imbalance between sources and sinks of atmospheric methane increased by 31 Tg a −1 from 2019 to 2020, representing a 36 Tg a −1 forcing (direct chan…
A tale of two regions
We use atmospheric observations to quantify methane (CH 4 ) emissions from Mexico’s most important onshore and offshore oil and gas production regions which account for 95% of oil production and 78% of gas production. We use aircraft-based top-down measurements at the regional and facility-levels to determine emissions. Satellite data (TROPOMI CH 4 data and VIIRS night-time flare data) provide independent estimates of emissions over 2 years. Our …
Sustained methane emissions from China after 2012 despite declining coal production and rice-cultivated area
China’s anthropogenic methane emissions are the largest of any country in the world. A recent study using atmospheric observations suggested that recent policies aimed at reducing emissions of methane due to coal production in China after 2010 had been largely ineffective. Here, based on a longer observational record and an updated modelling approach, we find a statistically significant positive linear trend (0.36 ± 0.04 ( ± 1 σ ) Tg CH 4 yr −2 )…
A gridded inventory of Canada’s anthropogenic methane emissions
Canada’s anthropogenic methane emissions are reported annually to the United Nations Framework Convention on Climate Change through Canada’s National Inventory Report (NIR). Evaluation of this policy-relevant inventory using observations of atmospheric methane requires prior information on the spatial distribution of emissions but that information is lacking in the NIR. Here we spatially allocate the NIR methane emissions for 2018 on a 0.1° × 0.1…
A gridded inventory of anthropogenic methane emissions from Mexico based on Mexico’s national inventory of greenhouse gases and compounds
We present a gridded inventory of Mexico’s anthropogenic methane emissions for 2015 with 0.1° × 0.1° resolution (≈10 × 10 km 2 ) and detailed sectoral breakdown. The inventory is constructed by spatially allocating national emission estimates from the National Inventory of Greenhouse Gases and Compounds constructed by the Instituto Nacional de Ecología y Cambio Climático (INECC). We provide additional breakdown for oil/gas emissions. Spatial allo…
