As the motorsport world converges on Singapore for the 2025 Formula 1® Grand Prix, the Marina Bay Street Circuit is once again in the spotlight — not only for its challenging racing conditions but also for leading sustainability performance among temporary race tracks worldwide.
As reported by Motors Inside, transforming 5 kilometres of bustling city streets into a high-speed racing venue each year is a complex operation, requiring 7,000 concrete barriers, over 100 kilometres of power and signal cables, and, from 2023, an all-LED lighting system. The circuit demands smart, efficient, and innovative sustainability solutions to meet the unique challenges posed by an urban environment.
For the second consecutive year, Marina Bay topped the Sustainable Circuits Index™ (SCI™) as the most sustainable temporary circuit globally, earning a platinum rating and demonstrating measurable progress across its environmental initiatives.
The SCI™, developed by Enovation Consulting in partnership with University College London’s Professor Paolo Taticchi, benchmarks sustainability performance across 117 motorsport circuits worldwide. Recognising the distinct challenges faced by permanent and temporary venues, the index evaluates each group separately but with a unified, robust methodology.
Temporary Street Circuits in Global Motorsport
Marina Bay is part of a select group of temporary street circuits used in top-tier international motorsport, alongside cities like Monaco, Baku, Las Vegas, Miami, and Jeddah. Unlike permanent tracks, these circuits operate on city roads temporarily closed ahead of race weekends, requiring agile sustainability strategies that adapt to the intricacies of urban infrastructure and tight timelines.
Waste Management and Circular Economy Practices at Marina Bay
With over 200,000 fans attending each year, Marina Bay produces a substantial waste footprint. The circuit park spans an impressive 772,000 square meters — equivalent to 618 Olympic-sized swimming pools — necessitating a strategic approach to waste.
Singapore’s waste management programme focuses on reduce, reuse, and recycle, supported by clear signage and fan education to encourage proper sorting. A digital Waste Management System (WMS) tracks and optimises waste flows, ensuring materials are efficiently routed to local Material Recovery Facilities (MRFs), energy recovery plants, or circular economy systems where recyclables are repurposed.
Diversifying Sustainability Efforts Beyond Waste
Alongside waste management, Marina Bay is driving sustainability progress across its operations, including:
Installing 1,300 solar panels on the Pit Building.
Eliminating approximately 160,000 single-use plastic bottles annually, supported by increased water refill stations.
Using Hydrotreated Vegetable Oil (HVO) in select generators, sourced from renewable materials.
Achieving a 40.1% reduction in Scope 1 and 2 greenhouse gas emissions between 2022 and 2024.
These initiatives underline the circuit’s commitment to lowering its environmental impact while enhancing the fan experience.
The Road Ahead for Temporary Circuits
While Marina Bay continues to lead, temporary circuits overall have room to improve — particularly regarding social sustainability and obtaining formal environmental certifications. Nonetheless, Singapore’s holistic approach and transparent reporting have set a benchmark that others should follow, demonstrating how temporary venues can evolve their sustainability performance in line with permanent circuits.
As motorsport embraces the challenge of sustainability, Marina Bay stands as a powerful example of sustainable innovation and quantifiable progress — proving that even the fastest street circuit can also be one of the greenest.
