sustainable supply chain

A zero-emission vehicle (ZEV) is a battery-powered vehicle that does not emit exhaust or other pollutants from its tailpipe. ZEVs are fully electric vehicles and must be plugged in to recharge.

What Is WAIRE?

Warehouse Actions and Investments to Reduce Emissions (WAIRE), sometimes called the Indirect Source Rule, is a truck traffic-based credit and deficit system impacting class 2B to class 8 trucks. Under the rule, some facility operators must monitor and submit accurate vehicle travel data, and they must earn a specified number of points through emissions-reducing activities or pay mitigation fees. The regulation also requires warehouses with ≥100,00 ft2 of indoor space within a single building to complete emission mitigation actions and investments.

Transport refrigeration units (TRUs) are climate-controlled devices that provide essential cooling or heating for consumer products being transported in various containers. They maintain a steady temperature for goods during transport or storage and allow the trailer to be cooled when the engine is shut off.

TRUs are also subject to state and federal regulations, most recently in the CARB TRU regulation mandating that owners and operators of truck TRU fleets in the state of California switch to zero-emission vehicle (ZEV) TRUs by a specified date.

Renewable diesel is an advanced fuel option that helps reduce greenhouse gas emissions. It is refined using plant-based oils and can be added to existing fuel truck systems to help lower a fleet’s carbon footprint.

An alternative fuel vehicle (AFV) is a vehicle that runs on alternative fuel rather than traditional gasoline or diesel. It uses alternative fuels such as electricity, natural gas, hydrogen, biodiesel or a combination of fuels. Common types of AFVs include electric vehicles or zero-emission vehicles, hybrid electric vehicles, compressed natural gas vehicles and hydrogen fuel cell vehicles.

Sustainability is taking on increased importance as companies respond to consumer trends and preferences, regulatory requirements, and environmental and climate impacts. Organizations are using their supply chains to better align with their environmental, social and governance (ESG) goals.

What Is Sustainability?

Sustainability is a business practice focused on shrinking a company's carbon footprint, reducing waste and saving money, while conducting operations in a socially and environmentally responsible way. Within the shipping industry, there are several ways to use the analytical power of network design tools to make supply chains focused more on sustainability. Some of these examples include shrinking the carbon footprint of freight operations, reducing waste and maximizing resource utilization, and supporting green operations.

As companies respond to increasing demand for sustainable products and services, the role of supply chain network design in supporting and furthering their green goals is gaining in importance.

The "take-make-dispose" approach to economic growth is becoming less tenable as more consumers demand sustainable products, and companies face increasing pressure to conserve the planet's finite resources.

Companies strive to get more products on a trailer and reusable containers offer that capability. They create significant cost savings when compared to throwaway packaging, and they eliminate variances in packaging. That, in turn, standardizes pack sizes, drives consistency and increases efficiency.
