This includes municipal vehicles, such as buses and trucks, as well as vehicles used by local companies for deliveries or transportation. Offering incentives and subsidies for the adoption of electric fleet vehicles can accelerate this transition.

Reducing emissions from cruise ships

Miami, the "cruise capital of the world", has taken steps to reduce air pollution from cruise ships, which contribute significantly to the city's air pollution. In 2021, the Port of Miami was awarded a $2 million grant from the U.S. Environmental Protection Agency (EPA) to reduce diesel exhaust emissions from cruise ships. This funding will be used to implement shore power, allowing ships to connect to the local electrical grid instead of idling their engines while docked. This initiative is expected to reduce harmful gas pollutants such as sulfur dioxide and nitrogen oxide emissions by 67% and 99%, respectively, while also reducing carbon emissions by up to 35%.

To further reduce emissions from cruise ships, several strategies can be implemented:

• Alternative Fuels: Cruise lines should transition to cleaner fuels such as hydrogen or ammonia instead of liquefied natural gas (LNG) or heavy fuel oil, which are highly polluting. LNG, while reducing particulate emissions, still contains methane, a potent greenhouse gas.
• Exhaust Gas Cleaning: The use of exhaust gas cleaning systems, such as scrubbers, can help reduce emissions from cruise ships. However, open-loop scrubbers must be avoided as they allow for the illegal discharge of sulfur into the sea. Closed-loop scrubbers are a better alternative as they store the scrubber effluent for safe disposal on land.
• Shore Power: Also known as "cold ironing," shore power allows cruise ships to plug into the electrical grid while docked, eliminating the need to idle their engines. This technology is already common in North America and some European ports, and its adoption should be accelerated globally.
• Advanced Wastewater Treatment: Treating sewage and greywater with advanced water treatment systems can help reduce the environmental impact of cruise ships.
• Single-Use Plastics: Cruise lines should continue initiatives to reduce single-use plastics on board, as plastic waste can have a significant environmental impact.
• Food Waste Management: Implementing food waste bio-digester technology can help reduce food waste on board cruise ships.
• Battery Power and Fuel Cells: Exploring new sustainable solutions, such as battery power storage systems and advanced fuel cell technology, can further reduce the environmental footprint of cruise ships.
• Emission Control Areas: Establishing additional Emission Control Areas, such as Sulfur Emission Control Areas (SECAs), can enforce more stringent fuel emission standards for cruise ships.
• Relocating Terminals: Moving cruise ship terminals away from densely populated areas can reduce the number of people exposed to air pollution.
• Transparency and Monitoring: Cruise lines should improve transparency and monitoring to ensure compliance with environmental regulations. This can include independent human monitors on board to observe and record all waste streams and discharges.
