Exhibit 99.1

Greenhaven Continuous Commodity Index Fund Announces Nearly All Available Units Issued

For Immediate Release

ATLANTA, March 26, 2009. Greenhaven Continuous Commodity Index Fund (NYSE-ARCA: GCC) announced today that due to an increase in requests for issuances of its Units of Beneficial Interest since the beginning of the trading week, of the 4 million Units authorized for issuance under its prospectus, all but one basket of 50,000 Units have been created and issued to date. As a result of this development, the creation of new Units will not be possible unless and until Greenhaven registers additional Units for issuance with the Securities and Exchange Commission.

Greenhaven confirmed that it intends to prepare documents to file with regulators in order to issue additional Units as soon as practicable, however, the timing of this process is dependent on a number of factors including the preparation of filings and regulatory review.

Greenhaven also announced that investors can still buy and sell Greenhaven Units on the NYSE and that the Fund continues to operate under its stated goal of tracking the Thomson Reuters Continuous Commodity Index. However, as a result of no Units remaining available for creation, a possibility exists that the price and value of the Units could diverge from the tracking of the Index.

This press release does not constitute an offer to sell or the solicitation of an offer to buy any securities.
