US government drops investigation into Exxon’s climate change response
Oil giant faces separate state investigations into whether it misled investors and the public about its knowledge of climate change

The US government has dropped a two-year investigation into how ExxonMobil Corporation factors climate-change regulations into its calculations of the value of its assets, the company said on Friday.
The Securities and Exchange Commission informed the energy giant in a letter dated Thursday that it would not recommend an enforcement action against the company at this time.
ExxonMobil cooperated with the inquiry, producing more than 4.2 million pages of documents, company spokesman Scott Silvestri said.
“After a thorough investigation, including a review of these documents, the SEC issued its closure letter,” he said.
Silvestri added that ExxonMobil is confident its financial reporting meets all legal and accounting requirements.
The SEC letter including standard language stating that the decision should not be construed as an exoneration and leaving open the possibility of further future action. The SEC declined to comment.
