MSCI assigns SpaceX a CCC rating
Rating agency MSCI has given SpaceX the lowest possible score in its latest ESG assessment, the CCC rating. The evaluation measures environmental, social and governance criteria that many investors use to gauge corporate sustainability.
Musk's brief reply on X
On the social platform X, formerly known as Twitter, SpaceX chief Elon Musk responded succinctly, stating that the concept of electric rockets is not viable with present technology.
Factors behind the rating
The poor rating stems from a mix of issues, including the use of conventional propellants, the environmental impact of launch operations, and governance concerns. MSCI noted that the aerospace sector faces unique sustainability challenges.
SpaceX's future direction
While the company has not announced any electric propulsion projects, it continues to refine the efficiency of its existing Merlin and Raptor engines and emphasizes reusability as a way to lower its carbon footprint.
Industry response
Market analysts view the ESG score as a signal that investors are increasingly scrutinizing the environmental impact of space activities. They also point out that developing truly electric launch systems would require substantial research and breakthroughs that are not on the near‑term horizon.
