Source Data and Code for "Closing Gaps in Emissions Monitoring with Climate TRACE"

Source Data: Closing Gaps in Emissions Monitoring with Climate TRACE  

Here, we provide two datasets and the R code that support the findings within the discussion section of our paper titled "Closing Gaps in Emissions Monitoring with Climate TRACE ". The paper assesses the current landscape of global greenhouse gas (GHG) emissions datasets along key dataset characteristics and reveals several limitations. These limitations motivate the development of the Climate TRACE dataset, which we introduce by evaluating it along the dataset characteristics. Both datasets are provided in .csv format and originate from the Climate TRACE dataset. Detailed descriptions of the methodologies used to estimate GHG emissions are available here. 

"city_level_annual_ghg.csv" provides annual greenhouse gas (GHG) emissions totals for 2010-2024 for 500 cities around the world, along with their population and gross domestic product (GDP). The data were used to assess changes in annual emissions over time and whether GDP impacts these trends. See column name descriptions below.

"ghg_timeseries_by_annex" provides annual emissions totals for Annex-1 (developed) versus non-Annex-1 (developing) countries 2015 to 2024. The data were used to investigate temporal emissions trends and whether UNFCCC status influences them. See column name descriptions below.
