John Mattson, President of Overimpact, in his examination of the need for carbon data in the maritime transport industry, points out that estimating greenhouse gas emissions alone is insufficient. He believes that direct and continuous measurement of carbon emissions can aid in better management and reduce operational costs.
Transformation in Measurement Methods
In recent years, the maritime transport industry has largely relied on estimating greenhouse gas emissions. These estimates were based on fuel consumption and standard emission factors and were reported periodically. However, today, carbon emissions directly impact operational costs, vessel performance, and investment decisions. Given these developments, direct and continuous measurement of emissions at their source has become a fundamental necessity.
Benefits of Direct Measurement
New analyses show that direct and continuous measurement of emissions can provide more reliable information than traditional estimates. This method allows operators to monitor emission changes based on operational conditions, load, route, and engine status. This information can help optimize operations and reduce costs.
Older models, especially methods A and B, primarily operate based on fuel delivery records or changes in tank levels, providing historical information. In contrast, direct measurement using sensors can measure gas emissions instantly and continuously, helping operators quickly identify changes.
This shift in measurement methods can provide more accurate information about the actual performance of vessels and the financial impacts of carbon emissions. For example, in carbon trading systems, transport companies must provide permits for each ton of verified emissions. Direct measurement can help reduce the number of permits required and consequently lower carbon costs.
By adopting this approach, transport companies can benefit from greater financial advantages and improve their performance in global markets. Ultimately, this change in approach can strengthen governance and accountability in the industry and base management decisions on real evidence.
