In the era of heightened global efforts to combat emissions and environmental impact, the commitment to achieve net-zero emissions by 2050 is transforming the landscape of industrial economies. Notably, the road infrastructure sector is poised to witness an annual investment of nearly $1 trillion over the next two decades. ranking it as the second-highest area of infrastructure investment.

Key stakeholders, ranging from road users to governments and investors, are set to play pivotal roles in steering a green transition in road transport. This transition holds the potential to significantly reduce emissions associated with energy use on road networks, construction materials, fleet operations, and both private and commercial vehicles.

The path ahead necessitates road operators to craft meticulous decarbonization roadmaps focused on five critical areas: enhancing energy efficiency and increasing renewable generation, facilitating sustainable mobility, promoting circularity, fortifying resilience to climate change, and implementing alternative tariff models.

Green Transition in Road Transport: An Overview

Globally, road transportation contributes to approximately 15 percent of total CO2 emissions and a staggering 74 percent of total transportation emissions. Road developers wield considerable influence over demand for construction materials and equipment, significantly impacting the carbon footprint of the industry.

Encouragingly, three influential groups are actively advocating for a green transition within the sector:

• Road Users: With 64 percent of drivers expressing environmental concerns, there is a growing interest in new-energy vehicles (NEVs), with 73 percent of sustainability-minded drivers preferring an NEV for their next vehicle.
• Governments: Increasing efforts and investments, exemplified by initiatives like NextGenerationEU, underscore the commitment to decarbonization.
• Investors: A rising focus on sustainability, evidenced by the green-bond market, showcases the financial sector's dedication to environmentally conscious investments.

However, embarking on the green transition in road transport presents formidable challenges, including substantial investments across the road value chain. Challenges include the pressing need for climate resilience, addressing high-impact Scope 3 emissions, and the imperative for new competencies and capabilities.

Navigating the Future: Strategies for Road Operators

To stay ahead of the curve, road operators must initiate comprehensive strategies focusing on:

1. Energy Efficiency and Renewable Generation:
   • Leveraging LED technology for road lighting replacement, reducing energy requirements by 20 to 30 percent.
   • Implementing distributed generation through photovoltaic (PV) systems for clean energy production.
2. Enabling Sustainable Mobility:
   • Expanding infrastructure for electric-charging and hydrogen stations, aligned with the projected 32 percent CAGR growth in electric-charging stations by 2028.
   • Developing intermodal hubs to facilitate the use of sustainable transportation modes.
3. Initiatives Promoting Circularity:
   • Embracing circular-economy initiatives, including recycled road surfaces, water runoff recovery systems, and measures for conserving biodiversity.
   • Exploring digital matchmaking platforms for circular marketplaces to enhance coordination within supply chains.
4. Resilience to Climate Change:
   • Implementing structural adaptation measures for new infrastructure capable of withstanding harsher environments.
   • Employing data, analytics, and advanced technologies for continuous monitoring and maintenance operations in response to extreme climate events.
5. Alternative Tariff Models for Sustainable Mobility:
   • Introducing dynamic toll systems, such as the free-flow system, to reduce travel times and traffic congestion.
   • Utilizing dynamic pricing based on virtuous behavior, time of use, or environmental parameters to incentivize sustainable practices.

In conclusion, as road operators chart their course for the future, these sustainable strategies offer a robust roadmap toward achieving the shared goal of a green and resilient road transport ecosystem.
