Sources: 2. Developments: 2. Maritime companies are implementing various technological and financial strategies to reduce carbon emissions in the shipping industry. Brazilian logistics firm Norsul reported avoiding approximately 13,000 tons of CO2 emissions between 2023 and 2025. The company achieved this through operational optimizations, such as route planning and speed adjustments, alongside technical interventions like electrostatic silicone-based anti-fouling coatings and electromagnetic pulse systems to reduce hull resistance and fuel consumption. In a separate development, the shipping company Norden partnered with Microsoft to pilot a maritime emissions reduction system. Utilizing the Roundtable on Sustainable Biomaterials (RSB) Book & Claim model, the initiative allows cargo owners to account for reduced emissions by purchasing verified reductions linked to biofuel use elsewhere in the industry. This mechanism decouples fuel consumption from emissions accounting, aiming to address logistical and financial barriers to scaling sustainable marine fuels. ## Timeline ### 2026-09-02: Norden and Microsoft pilot maritime emissions reduction system Norden has become the first maritime carrier to deliver verified emissions reductions via the RSB Book & Claim registry through a pilot project with Microsoft, targeting supply chain decarbonization. 2 sources. https://clstr.news/cluster/norden-and-microsoft-pilot-maritime-emissions-reduction-system ### 2026-08-14: Norsul reduces CO2 emissions through maritime efficiency Norsul, a Brazilian shipping company, avoided approximately 13,000 tons of CO2 emissions between 2023 and 2025 through operational optimizations and advanced anti-fouling technologies. 2 sources. https://clstr.news/cluster/norsul-reduces-co2-emissions-through-maritime-efficiency --- Cite as: Maritime industry decarbonization initiatives.
