Objective: Modern emergencymedical service (EMS) systems are vulnerable to both rising energy prices and potential energy shortages. Ensuring the sustainability of EMS systems requires an empirical understanding of the total energy requirements of EMS operations. This study was undertaken to determine the life cycle energy requirements of US EMS systems.

Methods: Input-output-based energy requirement multipliers for the US economy were applied to the annual budgets for a random sample of 19 metropolitan or county-wide EMS systems. Calculated per capita energy requirements of the EMS systemswere used to estimate nationwide EMS energy requirements, and the leading energy sinks of the EMS supply chain were determined.

Results: Total US EMS-related energy requirements are estimated at 30 to 60 petajoules (10(15) J) annually. Direct ("scope 1") energy consumption, primarily in the form of vehicle fuels but also in the form of natural gas and heating oil, accounts for 49% of all EMS-related energy requirements. The energy supply chain-including system electricity consumption ("scope 2") aswell as the upstream("scope 3") energy required to generate and distribute liquid fuels and natural gas-accounts for 18% of EMS energy requirements. Scope 3 energy consumption in thematerials supply chain accounts for 33% of EMS energy requirements. Vehicle purchases, leases, maintenance, and repair are the most energy-intense components of the non-energy EMS supply chain (23%), followed by medical supplies and equipment (21%).

Conclusion: Although less energy intense than other aspects of the US healthcare system, ground EMS systems require substantial amounts of energy each year.
