The Global Carbon Project (GCP) publishes an up-date of the global methane (CH4) sources and sinks to the atmosphere. This budget show that global methane emissions have increased by 9 % (about 50 Million tons) between 2000-2006 and 2017. Anthropogenic emissions appear to be the main contributors to this increase, with equal shares between fossil fuel sector and agriculture and waste sector.

The study was conducted by an international research team and led by the Laboratoire des Sciences du Climat et de l’Environnement (LSCE, CEA-CNRS-UVSQ) in France, under the umbrella of the Global Carbon Project that initiated the work. Two articles are published on July 15th in the journals Environmental Research Letters and Earth System Science Data.

Data Sources and Terms of Use

The use of data is conditional on citing the original data sources. Full details on how to cite the individual data are given at the top of each spreadsheet page. In order to facilitate comparison at regional scale, the region mask is provided on a 1°x1° grid as Netcdf files. For research projects, if the data are essential to the work, or if an important result or conclusion depends on the data, co-authorship may need to be considered. The Global Carbon Project – Methane facilitates access to data to encourage its use and promote a good understanding of the methane cycle. Respecting original data sources is key to help secure the support of data providers to enhance, maintain and update valuable data.
