Market-based solutions in the form of cap and trade systems are a key component of the comprehensive policies of ICAP members to combat climate change.

ICAP will contribute to the establishment of a well-functioning global cap and trade carbon market. ICAP provides the opportunity for members to share best practice and learn from each others' experience. State and regional programs must be in close contact with and have a clear line of sight to international programs as they design and implement their respective programs. By sharing knowledge and experiences, ICAP will enhance the design of other schemes and ensure that design compatibility issues are recognized at an early stage. As a result, ICAP will help make possible future linking of trading programs.
