“People are comparing it to the Internet boom of 1999,” said one green entrepreneur to the Washington Post, about the ruling, which gives finally gives Congress the right to regulate climate change.

In the majority opinion written by Justice John Paul Stevens, the court said that the EPA’s steadfast refusal to regulate greenhouse gas emissions presents a risk of harm to Massachusetts that is both “actual” and “imminent,” and that “The harms associated with climate change are serious and well recognized.”

Rob points to recent conversations, including comments by venture capitalist Randy Komisar (of big-name Silicon Valley venture firm Kleiner Perkins) that billion dollar IPOs are coming quickly. Indeed some are already filing for such IPOs, including former venture capitalist Martin Tobias’ Imperial Renewables. The Seattle biodiesel company plans an IPO that will value it at more than $1 billion.
