The Securities and Exchange Commission sees climate change as enough of a risk that it requires companies to disclose their climate-change-related risks in their annual 10k filings. Most, however, deal only cursorily with the potential for tightened regulation, without considering the many other threats to business operations that arise from a warming planet.

A recent report from sustainable business advocate Ceres found wide discrepancies in disclosure quality among oil and gas majors. Ceres found that BP (NYSE:BP), Suncor (NYSE:SU), and Eni (NYSE:E) provided the best disclosure overall, while ExxonMobil (NYSE:XOM) and Apache (NYSE:APA) did the worst.

  • Eni provided good disclosure by, among other things, mentioning specific emissions reductions for its combined cycle co-generation work, and providing a detailed discussion of its flaring and carbon capture and storage efforts.
  • BP's disclosure included a detailed analysis 
of the effects of indirect risks and opportunities on its operations. For example, BP disclosed that its "low-carbon businesses and future growth options outside oil and gas... have the potential to be a material source of low-carbon energy and are aligned with BP's core capabilities."
  • Suncor quantified the effects of existing regulations, and also described a basis for its conclusions about materiality. The company explained how it assesses
 future regulatory risks using a carbon price range.
  • ExxonMobil and Apache either only vaguely acknowledged various climate change risks or failed to discuss them at all.
