Yes, it is.
Here is background from Wikipedia (not the perfect source, but reasonable in this case):
The Trilateral Commission is a private organization, established to foster closer cooperation between United States, Europe and Japan. It was founded in July 1973, at the initiative of David Rockefeller; who was Chairman of the Council on Foreign Relations at that time. The Trilateral Commission is widely seen as a counterpart to the Council on Foreign Relations.
Speaking at the Chase Manhattan International Financial Forums in London, Brussels, Montreal, and Paris, Rockefeller proposed the creation of an International Commission of Peace and Prosperity in early 1972 (which would later become the Trilateral Commission). At the 1972 Bilderberg meeting, the idea was widely accepted, but elsewhere, it got a cool reception. According to Rockefeller, the organization could "be of help to government by providing measured judgment."
Zbigniew Brzezinski,[2] a professor at Columbia University and a Rockefeller advisor who was a specialist on international affairs, left his post to organize the group along with:
Henry D. Owen (a Foreign Policy Studies Director with the Brookings Institution)
George S. Franklin
Robert R. Bowie (of the Foreign Policy Association and Director of the Harvard Center for International Affairs) Gerard C. Smith (Salt I negotiator, Rockefeller in-law,
and its first North American Chairman)
Marshall Hornblower
William Scranton (former Governor of Pennsylvania)
Edwin Reischauer (a professor at Harvard)
Max Kohnstamm (European Policy Centre)
Other founding members included Alan Greenspan and Paul Volcker, both eventually heads of the Federal Reserve system.
Funding for the group came from David Rockefeller, the Charles F. Kettering Foundation, and the Ford Foundation.

Some of their works and ideas:
A Trilateral Commission Task Force Report, presented at the 1975 meeting in Kyoto, Japan, called An Outline for Remaking World Trade and Finance, said: "Close Trilateral cooperation in keeping the peace, in managing the world economy, and in fostering economic development and in alleviating world poverty, will improve the chances of a smooth and peaceful evolution of the global system."
Another Commission document read:
"The overriding goal is to make the world safe for interdependence by protecting the benefits which it provides for each country against external and internal threats which will constantly emerge from those willing to pay a price for more national autonomy. This may sometimes require slowing the pace at which interdependence proceeds, and checking some aspects of it. More frequently however, it will call for checking the intrusion of national government into the international exchange of both economic and non-economic goods."
The organization has come under much scrutiny and criticism by political activists and academics working in the social and political sciences. The Commission has found its way into a number of conspiracy theories, especially when it became known that President Jimmy Carter appointed 26 former Commission members to senior positions in his Administration. Later it was revealed that Carter himself was a former Trilateral member. In the 1980 election, it was revealed that Carter and his two major opponents, John B. Anderson and George H. W. Bush, were also members, and the Commission became a campaign issue. Ronald Reagan supporters noted that he was not a Trilateral member, but after he was chosen as Republican nominee he chose Bush as his running mate; as president, he appointed a few Trilateral members to Cabinet positions and held a reception for the Commission in the White House in 1984. The John Birch Society believes that the Trilateral Commission is dedicated to the formation of one world government.[4] In 1980, Holly Sklar released a book titled Trilateralism: the Trilateral Commission and Elite Planning for World Management.
Conservative critics claim the "Commission constitutes a conspiracy seeking to gain control of the U.S. Government to create a new world order." Mike Thompson, Chairman of the Florida Conservative Union, said: "It puts emphasis on interdependence, which is a nice euphemism for one-world government."
Sen. Barry Goldwater wrote in his book With No Apologies: "In my view, the Trilateral Commission represents a skillful, coordinated effort to seize control and consolidate the four centers of power: political, monetary, intellectual, and ecclesiastical. All this is to be done in the interest of creating a more peaceful, more productive world community. What the Trilateralists truly intend is the creation of a worldwide economic power superior to the political governments of the nation-states involved. They believe the abundant materialism they propose to create will overwhelm existing differences. As managers and creators of the system they will rule the future."
