In September 2023, as part of my work as a data scientist at the Joint Research Centre, I contributed to the GHG emissions of all world countries booklet.
The booklet is an annual output of the EDGAR database team (of which I am a member) and provides emissions time series from 1970 until 2022 for GHGs for all countries and for all anthropogenic sectors. EDGAR is used around the world as a highly-detailed, consistent and high-quality data source for research and policy making.
My particular role in this endeavour was calculating uncertainties on emissions estimates. This is a fairly complex procedure given the size and complexity of the database, and also due to issues such as skewed distributions and correlations. To do this I built a custom R package which is live-linked to the EDGAR database using SQL drivers. Uncertainties can be explored, visualised and exported internally via a Shiny app.
I’m quite proud of my contributions so far to the EDGAR project (although these are mostly internal), and pleased to be a part of a team that contributes significantly to climate change research and policy.
