Carbon offsets are frequently criticized by the press and some environmental advocates. Some observers object to “market-based” approaches for solving environmental problems, and oppose carbon offsets on that basis. Even those who are open to such approaches, however, often have reservations about carbon offsets. Their concerns fall into two categories:
- How carbon offset credits are used
- The quality of carbon offset credits
Some criticisms are more valid than others, but many have at least some validity and are important for buyers of carbon offset credits to keep in mind.
