Street Turns and Sustainability: Reducing Empty Miles and Emissions

A street turn reduces empty miles by reassigning inbound trailers directly to outbound loads, cutting fuel use and emissions. It is a practical, collaborative tactic for greener logistics.

Street Turns and Sustainability: Reducing Empty Miles and Emissions

Introduction

The logistics sector is responsible for a significant portion of global transport emissions, much of which stems from empty or unproductive vehicle movements. A Street Turn is a straightforward operational practice that directly reduces these empty miles by enabling an inbound trailer to be handed off to an outbound carrier immediately, avoiding an empty repositioning trip. Beyond cost savings, street turns offer a tangible pathway to lower carbon output and support corporate sustainability goals.

Why Street Turns Matter for Sustainability

Empty miles contribute disproportionately to fuel consumption and greenhouse gas emissions because a vehicle consumes nearly as much fuel moving empty as it does when loaded.

By converting what would be an empty movement into a revenue-generating trip, street turns:

• Reduce fuel consumption and CO2 emissions per freight move.

• Decrease vehicle wear-and-tear and associated resource use for maintenance and replacements.

• Lower congestion in yard and urban areas by cutting redundant trips.

Quantifying Impact

To make sustainability claims credible, measure the direct impact of street turns.

Key metrics include:

• Empty miles avoided: Multiply avoided miles by average fuel consumption to estimate fuel saved.

• Emissions reduction: Convert fuel saved into CO2e using standardized emission factors.

• Fleet utilization improvement: Percent increase in productive miles versus deadhead miles.

For example, if a street turn avoids a 50-mile deadhead and average diesel consumption is 6 mpg with CO2e factor of 10.16 kg per gallon, each avoided turn yields immediate emissions savings that scale with program volume.

Operational Levers to Maximize Environmental Benefits

To maximize sustainability gains from street turns, focus on the following levers:

• Prioritization of high-mileage lanes: Street turns on long lanes avoid more empty miles and yield greater emissions reductions.

• Technology-enabled matching: Use TMS algorithms and real-time tracking to quickly match inbound equipment availability to outbound demand.

• Carrier collaboration: Engage carriers with shared sustainability targets and incentives for reducing empty miles.

• Data-driven reporting: Track and report environmental KPIs as part of corporate sustainability reporting.

Policy and Collaboration Considerations

Sustainability gains from street turns are amplified by broader collaboration within the supply chain.

Consider these approaches:

• Shared performance goals: Include empty-mile reduction targets in carrier scorecards.

• Incentive programs: Offer reduced access fees or bonuses for carriers who perform agreed street turns.

• Public-private partnerships: Work with city authorities to designate secure handoff zones or consolidation hubs that facilitate safe street turns without causing congestion.

Challenges and Trade-offs

While street turns reduce emissions, they are not a standalone solution and require managing trade-offs:

• Security vs. convenience: Public handoffs can increase theft risk; secure transfer zones may require infrastructure investment.

• Operational complexity: Real-time coordination demands systems and communication protocols that may add administrative overhead.

• Regulatory constraints: Customs or bonded equipment rules may preclude some street turns, limiting potential impact on certain lanes.

Complementary Sustainability Strategies

Street turns are most effective when combined with other emissions-reduction tactics:

• Mode optimization: Shift where feasible from truck to rail or intermodal to lower per-mile emissions.

• Fleet fuel efficiency: Upgrade to more efficient engines, aerodynamic trailers, and low-resistance tires.

• Route optimization: Use planning tools to minimize mileage and idling time across the network.

Case Example

A national retailer implemented a street turn program focused on 10 high-frequency regional lanes. By using its TMS to pre-identify inbound trailers eligible for immediate reassignment, the retailer reported a 22% reduction in deadhead miles on those lanes over six months. When converted to emissions, the reduction equated to several hundred metric tons of CO2e avoided annually. Importantly, the retailer combined the street turn program with carrier incentives and improved yard signage to sustain adoption.

Communicating Results

To gain internal and external buy-in, communicate street turn results in sustainability reports and carrier performance reviews.

Useful presentation elements include:

• Absolute emissions reductions and percentage reductions in empty miles.

• Cost savings realized alongside environmental benefits to link sustainability and financial outcomes.

• Stories or spotlights on successful carrier partners and specific lane improvements.

Final Remarks

A Street Turn is a pragmatic, measurable way to cut both operational costs and carbon emissions. While it requires governance, agreed processes, and technology support, the environmental upside is clear: fewer empty truck miles, less fuel burned, and a lower carbon footprint for freight operations. For organizations pursuing net-zero and sustainable logistics strategies, street turns should be considered a foundational operational tactic — one that creates near-term wins while setting the stage for broader modal and fleet decarbonization initiatives.
