Republican lawmakers on Monday stepped up their verbal assault on the U.S. Securities and Exchange Commission’s mandate that public companies disclose their direct and indirect greenhouse gas emissions, as business groups and GOP-led states continued to mount legal challenges saying the SEC’s statutory authority is limited to financial matters, not environmental concerns. 

“The commission finalized the climate rule despite no clear congressional authorization,” said Rep. Bill Huizenga, R-Michigan and chair of the House Financial Services Subcommittee on Oversight and Investigations, at a field hearing in Lebanon, Tennessee.
