Carbon intensity of selected industrial sectors based on physical output, indexed (2010=1)

For consistency reasons, we used emission data from Joint Research Center (JRC) IDEES that only include CO₂ emissions. While CO₂ makes up the vast majority of Greenhouse Gas (GHG) emissions across these sectors, emissions of other GHGs are relevant in some production processes in chemicals and aluminium (N₂O and F-gases, respectively). For the sectors examined, trends in CO₂ emissions appear consistent with those in total greenhouse gas emissions. However, emissions reductions may be somewhat understated for parts of the chemical industry, where non-CO₂ GHG have declined more rapidly over time.
