Massive ocean-going vessels that rely on diesel fuel, their decks piled high with containers, are the most common method used by shipping industry decision-makers today. However, growing global concern about carbon dioxide emissions has heightened the need and desire to move away from this type of vessel in recent years.
Working toward realizing the universal goal of reducing emissions may not require waiting for the transformation of the world’s shipping fleet to electric power or another alternative green energy source. The reduction of global emissions can begin right now with your company.
Studies reveal that voyage optimization (including weather routing + speed management) can cut up to 55% of emissions. You can work toward your emission reduction targets right away by using real-time technology that will provide business insights on the complex challenge of reducing fuel consumption immediately.
SPOS by DTN is on the leading edge of this technology. Ship captains using this system can navigate trade routes with minimal fuel consumption, which equates to reduced emissions. Emissions are decreased by the real-time calculation of optimum routes while considering current and forecasted marine weather conditions.
Now DTN Vessel Routing API built on SPOS algorithms provide a recommended, weather-optimized route that any application can easily ingest for greater ease of use. With it, you can improve your safety and situational awareness, increase the accuracy of your ETAs, better anticipate likely delays, and reduce operational and logistical costs.
Powered by advanced AI, it also delivers critical metadata for each route, so your team can quickly and easily compare various options. The API’s versatility provides the flexibility needed to generate solutions via an endless combination of routing options, including:
- Shortest path: A path with minimal distance is calculated using the route network and great circle in open water. No other restrictions or weather optimization are considered.
- Instructed speed: A weather-optimized route is calculated with a given fixed speed along the route.
- Recommended speed: A weather-optimized route is calculated with a given range(s) of speeds; the most optimum speed is selected for the result.
- Variable speed: Recommends a variable speed along the weather-optimized route that will arrive closest to but before a given target ETA.
Let’s discuss carbon emissions, the ISO 2030 and 2050 benchmarks and how this powerful tool can help you reach those goals.
What are carbon emissions, and how does the shipping industry contribute to them?
What are carbon emissions exactly? Specifically, they are CO2 emissions, also known as carbon dioxide. Early education teaches us that plants and animals give out carbon dioxide during their respiration process. Plants and animals release CO2 into the atmosphere when they return to the soil through decomposition.
However, CO2 released in these ways and natural cycles into our atmosphere is not the same as greenhouse gases. Supporting science shows oceans take in roughly the same amount of carbon dioxide as they give out. It is only when human activities tip the perfectly balanced scales of nature that things become problematic.
Human activities like burning fossil fuels, cutting down too many carbon dioxide absorbing trees, and destroying carbon-storing forests are only part of the problem. Carbon dioxide is just one of the greenhouse gases that trap heat in our atmosphere. This complex problem of trapped heat leads to catastrophic consequences, as evidenced by today’s prevalence of extreme weather events.
Greenhouse gases are Carbon dioxide (CO2), Methane (CH4), Nitrous oxide (N2O); as well as fluorinated gases such as Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), Sulfur hexafluoride (SF6), and Nitrogen trifluoride (NF3).
Shocking statistics have emerged recently about the ocean shipping industry’s contribution to the global carbon emission problem. For example, if ocean shipping were a country, it would rank sixth if included on a list of countries where the volume of carbon emissions is measured.
To give this statistic some perspective, the shipping industry is responsible for releasing more CO2 each year than the entire country of Germany.
According to Fourth IMO GHG Study 2020, the share of shipping emissions in global anthropogenic GHG emissions has increased from 2.76% in 2012 to 2.89% in 2018.
Additionally, according to a Nov 12, 2021 article in the Guardian entitled, “The shipping industry faces a climate crisis reckoning – will it decarbonize?”, “Merchant ships burn approximately 300m metric tons of dirty fossil fuels each year, emitting roughly 1 bn metric tons of carbon dioxide in the process.”
IMO 2030 and 2050, what are their goals
Meeting emissions reduction challenges like falling in line with the lofty climate goals in the Paris agreement will not be easy. To appreciate the enormity of this challenge, the shipping industry’s emissions increased by 10% between 2012 and 2018. At this rate, the IMO predicts that by 2050 emissions from shipping could be 30% greater than they were in 2008.
To address these concerns, in 2011, the IMO mandated specific minimum requirements in connection with fuel efficiency. Then in 2018, the IMO introduced the further goal of reducing the shipping’s carbon pollution by at least 50% by the year 2050.
Initially, it may look like a modest target. In reality, it is quite ambitious, considering that this goal is expected to be achieved in tandem with significant global trade and economic growth.
More recently, in June 2021, the IMO’s Marine Environment Protection Committee brought in technical and operational measures to reduce greenhouse gas emissions produced by ships. These measures have the goal of a 40% reduction in the emission estimates of vessels by 2030.
