Tough new air pollution regulations for the maritime industry are making it difficult for the shipping industry to comply. The International Maritime Organization (IMO), the U.S Environmental Protection Agency (EPA) and the California Air Resources Board (CARB), to name a fe.w, have introduced new regulations to regulate air pollution. Steep fines and delays face maritime operators that do not comply with engine emissions monitoring and reporting. This is a challenge for shipping companies on several levels. First, despite being similar in some respects, the regulations often have different requirements, operating parameters and deadlines. Second, until recently the continuous, onboard emissions testing equipment and services required to monitor emissions have not existed.
