SpaceX is about to launch the largest rocket ever built—the Starship—while the world grapples with a crippling fuel crisis. The surprising truth: it's not making things worse, but it's raising profound climate questions that can't be ignored.
SpaceX, led by Elon Musk, is preparing for the first orbital launch of Starship from its Boca Chica facility in Texas in late May 2026. This comes as fuel prices spike globally due to supply constraints and geopolitical tensions. The company insists the launch won't exacerbate the fuel shortage. Why? Because Starship runs on methane and liquid oxygen, not the gasoline or diesel that consumers and industries are scrambling for.
Rocket propellant is a tiny fraction of global fuel demand. A single Starship launch consumes about 4,800 metric tons of propellant—mostly liquid oxygen and methane. But global daily oil consumption is over 100 million barrels. Even at SpaceX's projected high launch cadence, rocket fuel use remains negligible compared to aviation or trucking. The current fuel crisis is about crude oil and refined products; natural gas (the source of methane) is less constrained and not directly competing with road fuel markets.
However, the environmental calculus is more complex. Methane is a potent greenhouse gas. If any unburned methane escapes during launch or production, its warming potential is 84 times that of CO2 over 20 years. SpaceX uses methane because it can eventually be produced on Mars from water and CO2, but on Earth today it's mostly derived from fossil natural gas. The carbon footprint of each launch includes not just combustion emissions but also the energy to liquefy oxygen and methane.
Experts point out that the space industry's carbon impact, while small today, could grow rapidly if Starship enables mass space travel or megaconstellations. Some argue that space activities are a luxury in a resource-constrained world. Others counter that satellite technology already helps monitor climate change and improve efficiency. The fuel crisis highlights a deeper tension: even 'cleaner' rocket fuels like methane still rely on fossil feedstocks.
Looking ahead, SpaceX plans to increase Starship launches to multiple per week. The company is developing renewable methane production using carbon capture, but that remains experimental. Regulatory scrutiny is likely to intensify. The launch may proceed as scheduled, but the debate over space's role in a resource-strapped and warming world is only beginning.

Key Takeaways
- Starship uses liquid methane and liquid oxygen as propellant, not gasoline or diesel, so its launch fuel does not directly compete with road transportation fuels at the pump.
- A single Starship launch consumes approximately 4,800 metric tons of propellant, but global daily oil demand exceeds 100 million barrels—making rocket fuel demand negligible in the current crisis.
- Methane has a global warming potential 84 times greater than CO2 over 20 years, and any leakage during production or unburned methane in the exhaust raises significant climate concerns.
- SpaceX's methane is currently sourced from natural gas, but the company has announced plans to produce methane synthetically using carbon capture and renewable energy—a technology still in early stages.
- The launch comes as fuel prices in the U.S. and Europe have risen over 30% year-on-year due to refinery closures and geopolitical tensions, prompting questions about prioritizing spaceflight during a crisis.
Frequently Asked Questions
SpaceX is launching Starship because the rocket uses methane and liquid oxygen, not gasoline or diesel. These fuels are not directly competing with the refined petroleum products at the heart of the current fuel crisis. The launch is part of a test campaign that has been scheduled for months.
No. Starship’s propellant is methane derived from natural gas, and the total amount used per launch is negligible compared to global oil demand. The fuel crisis is about crude oil and road fuels; rocket propellant represents a tiny, separate supply chain.
Starship uses liquid methane (CH4) as fuel and liquid oxygen (LOX) as oxidizer. This combination is chosen for high performance and the potential for in-situ resource utilization on Mars.
A single Starship launch uses about 4,800 metric tons of propellant. A long-haul flight burns roughly 150 metric tons of jet fuel. While Starship’s numbers are large, its launch cadence is low compared to the thousands of daily flights.
Methane is a potent greenhouse gas; unburned methane in rocket exhaust or leaks during production can have a warming effect up to 84 times that of CO2 over 20 years. The cumulative impact of frequent launches could be significant.
Currently, SpaceX uses methane from fossil natural gas. The company has stated plans to eventually produce methane using carbon capture and renewable energy, but this technology is not yet deployed at scale. The long-term sustainability depends on transitioning to green methane production.
