Al Gore’s venture capital firm has invested $6 million in a software company that stands to make billions of dollars from cap-and-trade regulation — further fueling controversy that Gore lied about his profiteering from cap-and-trade to Rep. Marsha Blackburn (R-TN) and the House Energy and Environment Subcommittee during testimony in April.

Hara Software sells software to help track greenhouse gas emissions. The market for such software is now about $2.5 billion dollars in size, and is expected to grow by a factor of ten to $25 billion if cap-and-trade legislation is enacted, according to Hara CEO Amit Chatterjee.

Kleiner Perkins, a venture capital firm in which Al Gore is a partner, invested in Hara just last year. Chatterjee told Reuters that,

“This company would not have existed if Al Gore had not bought off on the idea.”

Gore is also under fire for lying to Rep. Steve Scalise (R-LA) at the same congressional hearing about his relationship with Goldman Sachs.

Operating as a stealth tax, cap-and-trade will make the vast majority of Americans poorer and less free — but Al Gore, Kleiner Perkins, Amit Chatterjee and Hara will be laughing all the way to the bank.
