Name Change for the Policy & Market Tool

The carbon reward policy and the associated market instrument have undergone name changes and structural changes as the policy was developed. The most contemporary version of the policy is defined by Chen (2025). Between 2021-2024, the policy was also called “Carbon Reward”, but the tool was called “Carbon Currency (XCC)”. The tool is now named “Carbon Reward (XCR)” because it is not a currency. The tool (XCR) should not be confused with the “carbon coin” that appears in the fictional novel by K. S. Robinson (2020) although the carbon coin was actually inspired by the carbon reward policy. Prior to 2021, an older policy was developed, called “Global 4C,” and it used an older version of the tool, called “Complementary Currencies for Climate Change (4C)”. It should be noted that the contemporary policy does not employ a complementary currency or parallel currency, and this is because the carbon reward instrument (XCR) is not a medium of exchange. These name changes were necessary to improve our understanding of the policy and its instrument.
