| description | <p>We present an updated version of the Global Fuel Exploitation
Inventory (GFEI) for methane emissions and evaluate it with results from
global inversions of atmospheric methane observations from satellite (GOSAT)
and in situ platforms (GLOBALVIEWplus). GFEI allocates methane emissions
from oil, gas, and coal sectors and subsectors to a 0.1<span class="inline-formula"><sup>∘</sup></span> <span class="inline-formula">×</span> 0.1<span class="inline-formula"><sup>∘</sup></span> grid by using the national emissions reported by individual
countries to the United Nations Framework Convention on Climate Change
(UNFCCC) and mapping them to infrastructure locations. Our updated GFEI v2
gives annual emissions for 2010–2019 that incorporate the most recent UNFCCC
national reports, new oil–gas well locations, and improved spatial
distribution of emissions for Canada, Mexico, and China. Russia's oil–gas
emissions in its latest UNFCCC report (4.1 Tg a<span class="inline-formula"><sup>−1</sup></span> for 2019) decrease by
83 % compared to its previous report while Nigeria's latest reported
oil–gas emissions (3.1 Tg a<span class="inline-formula"><sup>−1</sup></span> for 2016) increase 7-fold compared to
its previous report, reflecting changes in assumed emission factors. Global
gas emissions in GFEI v2 show little net change from 2010 to 2019 while oil
emissions decrease and coal emissions slightly increase. Global emissions
from the oil, gas, and coal sectors in GFEI v2 (26, 22, and 33 Tg a<span class="inline-formula"><sup>−1</sup></span>,
respectively in 2019) are lower than the EDGAR v6 inventory (32, 44, and 37 Tg a<span class="inline-formula"><sup>−1</sup></span> in 2018) and lower than the IEA inventory for oil and gas (38
and 43 Tg a<span class="inline-formula"><sup>−1</sup></span> in 2019), though there is considerable variability between
inventories for individual countries. GFEI v2 estimates higher emissions by
country than the Climate TRACE inventory, with notable exceptions in Russia,
the US, and the Middle East where TRACE is up to an order of magnitude
higher than GFEI v2. Inversion results using GFEI as a prior estimate
confirm the lower Russian emissions in the latest UNFCCC report but find
that Nigeria's reported UNFCCC emissions are too high. Oil–gas emissions are
generally underestimated by the national inventories for the highest
emitting countries including the US, Venezuela, Uzbekistan, Canada, and
Turkmenistan. Offshore emissions tend to be overestimated. Our updated GFEI
v2 provides a platform for future evaluation of national emission
inventories reported to the UNFCCC using the newer generation of satellite
instruments such as TROPOMI with improved coverage and spatial resolution.
This increased observational data density will be especially beneficial in
regions where current inversion systems have limited sensitivity including
Russia. Our work responds to recent aspirations of the Intergovernmental
Panel on Climate Change (IPCC) to integrate top-down and bottom-up
information into the construction of national emission inventories.</p> |
