Marine Transportation: A Good News Story For Safety and the Environment

Marine Transportation – GHG Emissions
~99% of Kirby’s emissions are from the marine transportation fleet

Kirby Corporation – GHG Emissions Summary
Scope 1 Emissions Performance
~99% of Kirby Corporation Scope 1 GHG emissions come from the operation of the marine transportation boat/barge fleet
Ultra low sulfur diesel fuel consumption and CO2e emissions have declined 12% since 2015 despite significant growth in the number of vessels in
the fleet
– 2018: Higman, Targa, CGBM acquisitions added ~5.4 million barrels of capacity and 75 towboats
– 2019: Cenac acquisition added ~1.8 million barrels of capacity, 34 towboats, and 2 offshore tugboats
– 2020: Savage acquisition added ~ 2.5 million barrels of capacity, 45 towboats
Emissions data reporting project launched in 2020 to better understand Kirby’s emissions footprint on a micro level
Scope 2 Emissions Performance
100% of Scope 2 energy is consumed from the grid
– ECO Solutions Champion issued ~6,000 renewable energy certificates in 2021; 100% renewable representation
~25% of Scope 2 energy is renewable
*2021 Scope 2 excludes 6,000 MWh of electricity consumed from renewable sources
Decarbonizing Initiatives – 40% Reduction By 2040
When it comes to decarbonizing the company, Kirby is pursuing many paths in order to achieve best results.

- Proprietary in-house design, development, and construction underway for a diesel-electric inland push boat incorporating an energy storage system (ESS) to significantly reduce emissions
- Ready for service in 2023
- Flexible battery design allows for adding or removing battery packs based on power needs
- Reduced maintenance schedule and costs against conventional vessels
- Efficiency gains in multiple operating modes
- Fuel savings up to 30-80%:


- Hybrid Drive with 2 Generators (1130 kW)
- Battery Pack : 1243 kWh
- Charge time at dock (480 VAC, 200A) : 6 hrs
Kirby Offshore Marine

Kirby Offshore Wind
Kirby enters the renewable energy space through a 20 year partnership with Maersk
‒ Kirby will provide barge transportation services for offshore wind towers and turbines to Maersk Supply Service
‒ First project is Empire Offshore Wind, a joint
venture between Equinor and bp off the
coast of New York


Going Above and Beyond – Marine Transportation

Limiting our Impact on the Environment

As engine tier level increases, engines produce less emissions and become more efficient and environmentally friendly
Engine Tier Strategy
Since entering the offshore market Kirby’s investment strategy has reduced Tier 0 engines by 95%
Since 2015 Kirby’s investment strategy has spent
$200M+ on Tier 3 and 4 engines and boats
Kirby is committed to a cleaner and more efficient offshore fleet
Since 2017, Kirby Inland Marine has spent over $9 million dollars investing in solar panels for over 600 barges that power the high-level alarm systems
- Allows the barges to load and discharge at facilities that do not have high level alarm hook ups on shore
- Ensures tankerman can use the alarm system on loads and discharges which gives them a safety system to help prevent spills to the environment
