Trilogy Sustainability and Carbon Program

A leader in the tourism industry and grounded in sustainable operations, Trilogy Excursions in Maui, Hawaii, has long worked to minimize its impact on ocean resources. In an industry flooded with eco claims, Trilogy chose a different path—forgoing labels in favor of meaningful action with substantive community impact. As it explored becoming a zero-carbon company—and in the wake of Maui’s devastating wildfires—Trilogy reassessed its priorities to stay true to its guiding principles and maximize its positive impact on the local community. Stok was proud to support Trilogy along this journey, providing clarity and realistic, actionable sustainability goals for community benefit.

The Challenge

Trilogy initially engaged Stok to explore net-zero carbon feasibility and strategies, and to support informed, realistic decisions around the company’s sustainability goals. When wildfires struck Maui, the team paused to redefine what sustainability meant for Trilogy, focusing on rebuilding and strengthening its community. Stok supported these efforts through:

  • Conducting a greenhouse gas (GHG) and resource inventory.
  • Leading a revisioning session to connect sustainability with Trilogy and its Hawaiian roots.
  • Delivering actionable sustainability plans centered on community impact.
“As a company long committed to protecting our ocean resources, we wanted to explore becoming a zero-carbon company but needed an expert to guide us. Stok helped us focus our efforts, providing clarity and support every step of the way. When the Maui wildfires hit, Stok pivoted with us, helping redefine our sustainability priorities toward local, community-driven impact. Their dynamic support—from conducting GHG inventories to delivering actionable sustainability plans—has been invaluable. With Stok as our trusted partner, we’re confident in the steps we’re taking to create real, lasting benefits for our community.”

The Solution

ZERO-CARBON COMPANY EXPLORATION

Inspired by industry peers, Trilogy explored a zero-carbon future for itself. Stok conducted a GHG inventory, supplemented by a resource inventory including unique materials like recycled scuba and dive gear. Alongside this list and quantification of Trilogy’s emissions sources, Stok provided a tracking mechanism for ongoing operations.

ENVISIONING COMMUNITY-ORIENTED SUSTAINABILITY

Following the Maui fires, sustainability priorities shifted from global impact to local resilience. The team assembled to revision the meaning and purpose of sustainability for Trilogy, realigning with Trilogy’s longtime focus on benefiting its local community. Stok helped Trilogy identify three key sustainability focus areas—procurement, waste, and energy use—that would directly engage and strengthen the local community.

To advance Trilogy’s sustainability ambitions, Stok delivered sustainability plans for the three areas identified in the revisioning session, each including options for goal setting and strategies for achievement. For energy use, though Trilogy relies on marine-grade diesel and B-100 biodiesel fuel to run its fleet of boats, electric boat motors and battery storage solutions are not yet proven, reliable, or readily available to meet the needs of the type and size of vessels that comprise Trilogy’s fleet. Instead of financially burdening the company to reduce or negate these emissions, Trilogy is focusing on other sustainability initiatives with tangible community benefits. Highlights include:

      • Procurement: Prioritizing local sourcing to revitalize the community economy while integrating environmentally friendly purchasing, such as reef-safe cleaning products.
      • Waste: Implementing a food waste composting program to aid Lahaina town revival and replanting efforts, as well as working with Maui County and state harbors to develop a harbor recycling program.

Following the wildfires, Stok was honored to support Trilogy pro bono through Stok’s Pro Bono Program.
