Inspired by a research article in one of my classes in college senior year, I attached its URL but the full text needs authorization so I also put on an image here just for knowledge of one point of the paper. If interested, ask me for the full PDF!
The paper addressed that disagreements between major emissions inventories exceed 100% for large urban areas of the northeastern U.S. and that urban emissions comprise widely varying shares of state-level emissions, from 22% in VT to 85% in NJ. The researchers introduced the Anthropogenic Carbon Emissions System (ACES) which gives an improved spatial representation of urban emissions at 1 square meter resolution, a new bottom-up estimate of hourly sector-specific estimates of carbon emissions at the spatial and temporal scales as part of a prototype carbon monitoring system (CMS) for the northeastern U.S.
Current global inventories of FFCO2 emissions do not directly quantify emissions at local scales; instead, spatial proxies like population density, nighttime lights, and power plant databases are used to downscale emissions from national totals. Even though the estimated global uncertainties of FFCO2 emissions fall in the range of 6–10%, urban-specific carbon emission measurement can still benefit from the newly developing bottom-up approach in this study, improving the accuracy and efficiency to monitor carbon and energy flows in cities.
