2 years ago @yoelcortes Thank you for bringing this topic back up! My normal tools are Okular which has a great table extractor feature and ScanTailor although this one is digital already so no scanning is necessary.
I can help with this task also. Attached is the extracted data from the PDF as a spreadsheet in a table. The "work items" are as follows as they look to me now:
- Obtain the CAS numbers for each component. This is the slowest part in my experience.
- Convert lifetimes which are in days into floating-point fractional years.
- Make column headers consistent between the GWP files.
- Decide if the AGWP values should be included.
- Remove empty rows.
- Decide what to do about "<1" values.
- Add the file
- Modify the code
- Add a couple tests
- (maybe) change the default to the new values.
I hope the spreadsheet is helpful. Thank you for your continued collaboration. Splitting out Chemicals into its own project was definitely a good call.

Is your feature request related to a problem? Please describe. The GWP lookups do not have updated data for the IPCC report from 2012. It is important to update the data to include the new values.
Do you acknowledge the project is developed by volunteers adding features primarily for their own purposes? Yes, and I have a purpose for it.
Additional context Table can easily be copied from this official PDF: https://www.sealevel.info/AR5_Table_8.A.1_Lifetimes_Radiative_Efficiencies_and_Metric_values_pp_731-738.pdf Will likely simply update the existing file which is loaded to include the new values. Likely should update the default method to use the new values.
