IETA and the International Bank for Reconstruction and Development (World Bank)represent two important actors in the new market. The International Bank for Reconstruction and Development (World Bank) was the first to develop a global carbon fund as a public/private partnership - the Prototype Carbon Fund (PCF) -and has gone on to create a whole family of funds and capacity building facilities designed to expand the volume of trade with its borrowing countries, reduce risk, and extend the reach of carbon finance into diverse niches in the market.

IETA is an association of over 80 leading companies from around the world, from all stages of the carbon business cycle, dedicated to the creation of a global greenhouse gas market. IETA was created by leading business organizations to be the main voice of the business community focused on the greenhouse gas market and the role of mechanisms in meeting the challenge of climate change.

IETA and the International Bank for Reconstruction and Development (World Bank) share a long and fruitful relationship that includes the creation of the Community Development Carbon Fund, which is dedicated to purchasing emission reductions from poor countries and rural areas, the Validation and Verification Manual, and jointly sponsored training programs in carbon finance. Together their credibility in the marketplace and combined membership will be sure to make the Carbon Trade Fair a successful experience.
To further ensure the success of the event, Koelnmesse was the natural choice to join forces with, as they are the number one trade fair location for 25 industrial sectors. Koelnmesse is located in Cologne, Germany considered the heart of Europe and symbolically the ancient Roman trading city.
