The Blue Origin rocket, owned by Jeff Bezos, used liquid hydrogen and liquid oxygen as fuel. The BE-4 engine, developed by Blue Origin, uses an oxygen-rich, liquefied methane fuel. The New Shepard rocket, which Bezos rode on its initial crewed flight, combines liquid oxygen in its engine to generate thrust. This means the main emissions are water and some minor combustion products, and virtually no CO2.

What You'll Learn
The Blue Origin rocket used liquid hydrogen and oxygen
The Blue Origin rocket, named New Shepard, used liquid hydrogen and oxygen as a propellant. This is in contrast to other rockets, such as SpaceX's Falcon 9, which uses kerosene, and NASA's new Space Launch System, which uses liquid hydrogen.
The BE-3 engine, developed by Jeff Bezos' company, burns liquid hydrogen and liquid oxygen. This combination does not produce carbon dioxide emissions, unlike conventional rocket fuels, which are carbon-based. However, the Blue Origin rocket's emissions primarily consisted of water vapour and other combustion products.
While the rocket did not emit carbon dioxide, a major greenhouse gas, it did release other substances into the atmosphere. Water vapour, for instance, can have warming effects on the climate, and other chemicals can harm the ozone layer. Additionally, the energy required to produce the hydrogen used in the rocket's fuel also contributes to the environmental impact.
Despite the lack of carbon dioxide emissions, critics have raised concerns about the overall environmental impact of rocket launches, especially as the space tourism industry grows. The Blue Origin rocket's propulsion system burned liquid hydrogen and oxygen, resulting in emissions that, while not carbon dioxide, still have potential climate and environmental implications.

No carbon dioxide was emitted, unlike other rockets
The New Shepard rocket, which took Jeff Bezos to space, did not emit carbon dioxide. The BE-3 engine developed by Bezos' company burns liquid hydrogen and liquid oxygen, which produces water vapour and other combustion products, but not carbon dioxide.
Eloise Marais, an air pollution researcher at University College London, confirmed that "carbon dioxide isn't emitted from the Blue Origin rocket". She added that "while there are a number of environmental impacts resulting from the launch of space vehicles, the depletion of stratospheric ozone is the most studied and most immediately concerning".
Marais and other researchers warn that every rocket poses a threat to the ozone layer, whether it is from water vapour, nitrogen oxides, or particles from conventional rocket fuels. These emissions stay in the upper atmosphere for a long time, from two to three years. The ozone layer can be destroyed by the combination of elements from burning fuels.
While the Blue Origin rocket did not emit carbon dioxide, it is not a net-zero environmental solution. The production of hydrogen fuel requires a lot of energy, and the rocket's emissions of water vapour and nitrogen oxides can still harm the atmosphere and deplete the ozone layer.
Additionally, the indirect emissions associated with rocket launches, such as those required to construct the rocket, can be significant. Lucas Chancel, co-director of the World Inequality Lab, estimated that "at least 50 tonnes of CO2" were emitted before the Blue Origin spacecraft even left the launchpad.

The engine produces water vapour and combustion products
The Blue Origin rocket, developed by Jeff Bezos, uses a BE-4 engine, which runs on liquid oxygen and liquefied methane. This engine does not emit carbon dioxide, a major greenhouse gas, as a result of the combustion of these propellants. However, the New Shepard rocket does produce water vapour and combustion products as by-products of its fuel usage.
Water vapour is released into the upper atmosphere, where it can remain for two to three years. While water vapour is not typically considered a pollutant, it can have warming effects on the climate when trapped in the atmosphere. This impact is further exacerbated by the presence of other chemicals and combustion products, which can contribute to the degradation of the ozone layer.
The BE-4 engine produces 2,400 kN (550,000 lbf) of thrust at sea level, and its development was funded through private investment and public contracts. The engine was initially intended for Blue Origin's New Glenn launch vehicle but has since been adopted by the United Launch Alliance (ULA) for their Vulcan Centaur rocket.
While the New Shepard rocket does not emit carbon dioxide, it is important to consider the environmental impact of water vapour and other combustion products released into the atmosphere. These emissions can have a significant effect on the climate and the ozone layer, even if they are not as harmful as carbon dioxide emissions.
Additionally, it is worth noting that the production of hydrogen, which is used in the rocket's fuel, requires a significant amount of energy. This energy generation can contribute to carbon emissions, even if the rocket itself does not emit carbon dioxide during its operation.

The BE-4 engine uses liquefied methane fuel
The BE-4 engine, developed by Blue Origin, uses liquefied methane fuel. Blue Origin is Jeff Bezos's company, and the BE-4 engine was used in the New Shepard rocket, which successfully completed a space flight in July 2021.
The BE-4 engine is a liquid rocket engine that operates on a staged combustion cycle. It produces 2,400 kN (550,000 lbf) of thrust at sea level. The engine's development was funded through a combination of private investment and public contracts. The BE-4 engine first flew aboard the Vulcan Centaur rocket on January 8, 2024, and later on the New Glenn rocket on January 16, 2025.
Methane is chosen as the fuel for the BE-4 engine due to its reusability and clean-burning properties. Methane has a simple chemical structure, which allows it to burn more cleanly than other fuels. This is particularly advantageous for reusable engines, as it eliminates the need for periodic cleaning. Additionally, methane allows for autogenous pressurization, which is the use of gasified propellant to pressurize liquid propellant. This eliminates the requirement for separate pressurization systems, further simplifying the engine design.
The use of methane fuel in the BE-4 engine also offers cost advantages. Methane is a cheaper alternative to other fuels such as RP-1. As fuel typically contributes significantly to the overall cost of a vehicle, selecting methane as the fuel of choice can result in substantial cost savings.
In summary, the BE-4 engine's utilization of liquefied methane fuel showcases Blue Origin's focus on reusability, clean-burning properties, and cost-effectiveness. By selecting methane, they have addressed some of the challenges associated with traditional rocket fuels while also paving the way for potential future applications, such as space exploration to Mars.

Bezos' rocket was environmentally friendly compared to others
The Blue Origin rocket, founded by Jeff Bezos, used liquid hydrogen and liquid oxygen as fuel. This is unlike conventional rocket fuels, which are carbon-based. As a result, the Blue Origin rocket did not emit carbon dioxide, a major greenhouse gas. Bezos himself claimed that the rocket used "the most environmentally benign propellant you can choose".
However, this does not mean that the rocket was entirely environmentally friendly. Eloise Marais, an air pollution researcher at University College London, stated that every rocket poses a threat to the ozone layer. While the Blue Origin rocket did not emit carbon dioxide, its main emissions were water vapour and other combustion products. Marais notes that water vapour and other chemicals trapped in the atmosphere can harm the climate. Furthermore, the production of hydrogen, which the rocket burns, requires a lot of energy.
Compared to other rockets, the Blue Origin rocket was relatively environmentally friendly in terms of carbon emissions. Other private companies, such as SpaceX and Virgin Galactic, use conventional fuels that release carbon dioxide. However, it is important to note that the lack of regulations around rocket emissions may pose a challenge to the environment as the space tourism industry grows.
Overall, while the Blue Origin rocket did not emit carbon dioxide, it still had some environmental impacts, and the cultivation of tourism and popular use of rockets could come with vast environmental costs.
