One Space Trip Emits a Lifetime's Worth of Carbon Footprint (futurism.com) 201

An anonymous reader quotes a report from Futurism: In a revelation that will surprise almost no one, the 2022 World Inequality Report found that one space flight emits more carbon dioxide than most of the world's population will create in their entire lifetime. While other parts of the report focus on labor, income and economic inequality, the researchers also included a statistic -- spotted by folks on social media and highlighted by Gizmodo -- that perfectly sums up the relationship between those who create greenhouse gases versus those who suffer most from them.

"Perhaps the most conspicuous illustration of extreme pollution associated with wealth inequality in recent years is the development of space travel," the report states. "An 11-minute flight emits no fewer than 75 tonnes of carbon per passenger About one billion individuals emit less than one tonne per person per year. Over their lifetime, this group of one billion individuals does not emit more than 75 tonnes of carbon per person." If you're wondering which space flight the World Inequality Report is addressing, well, the team didn't call anyone out by name. But Jeff Bezos' much-publicized space flight back in July was about that length of time, as Gizmodo pointed out. Bezos, the Amazon founder currently wrapped up in Blue Origin's space tourism junket, effectively puts out more carbon than most humans could create in their lifetime each time he sends up a rocket.

The World Inequality Report argues that to hold the biggest greenhouse gas emitters responsible, we need to better track global emission numbers. "Large inequalities in emissions suggest that climate policies should target wealthy polluters more," the authors write. "So far, climate policies such as carbon taxes have often disproportionately impacted low and middle income groups." It's the equivalent of being told to recycle your cardboard and pay for municipal recycling pickup, in other words -- it's a nice gesture, but no matter how hard you try, you'll never offset a single Bezos space journey.
"The report also noted that the top 1% wealthiest individuals emit about 110 tons of carbon emissions per year, an extreme number dwarf by the top .1% (467 tons) and the top .01% (2,530 tons)," notes Gizmodo.

What's absent from the report, however, are the everyday benefits of space exploration, such as scientific discoveries and the creation of scientific and technical jobs, among other things. The tradeoff between the negative carbon emissions and positive benefits of space travel remains to be seen.

One Space Trip Emits a Lifetime's Worth of Carbon Footprint

  • SpaceX is trying to transition to sub-cooled methane and oxygen, which produces less CO2 emissions.

    Technology is already advancing beyond this concern. Furthermore, if you can shift some manufacturing off Earth thanks to heavy lift with reasonable costs like Starship, then you have reduced overall CO2 emissions.

          No, it's not greenwashing. There is no methane on Mars. The whole point of building Starship with methane engines is that methane can be made from water and CO2, both of which are available on Mars. It's called the Sabatier process: https://en.wikipedia.org/wiki/... [wikipedia.org] SpaceX has already started making methane on Earth and plans to scale up so it can provide fuel for all its launches.

              If SpaceX manufactures their methane from atmospheric CO2, using energy from non-fossil energy sources, it will be carbon neutral on Earth.

            • If people are going to land on Mars then the people going will take nuclear reactors with them or there will be nuclear reactors on Mars waiting for them. We have no other technology with the required energy density and reliability to support human life on Mars. They will likely have solar panels too, maybe even windmills, but they will certainly use nuclear power.

          You can make methane by reacting CO2 with hydrogen, by the Sabatier reaction [wikipedia.org]. "Green" hydrogen can be produced by electrolysis of water, using electricity from renewable sources. However, this is not not where most methane comes from at present, so maybe carbon neutral methane is a bit unlikely.

        Does it really?

        Compare it to private jet use. A G5 emits a little over four tons per hour of flight, so this flight to space is equivalent to 18 hours of air travel, a flight from New York to Honolulu and back. Also note the carbon emissions of the 0.1%, mentioned in the summary: 2530 tons per year. So for those wealthy enough to fly to space, taking a suborbital hop every year would only increase their personal emissions by 3%.

        I'm not saying it's a good thing, just pointing out that these joyrides don't constitute a significant contribution to climate change, not compared to everything else. Not even compared to just the other stuff that rich people do.

I was having trouble finding numbers, but that seems likely to be more than the actual propellant weight carried, and for SpaceX 2/3 of their propellant weight is lox. 75 tonnes of C is not the same as 75 tonnes of CO2; 75 tonnes of CO2 per passenger might be approaching believable, but I have a really hard time believing they're burning 225 tonnes of fuel per passenger.

So is 21 about equal to 518?

    Carbon could have been emitted if the hydrogen was steam reformed from natural gas, but hydrogen can also be produced using water and electricity.

Up to about 25,000 km of the cable would wrap around the equation in the event that the cable snaps above that height. Above 25,000 km it will probably burn up during re-entry and/or snap a second time and get flung out into a higher orbit.

    The simplest solution is to make the people who shelled out millions for the ride shell out a few thousand more to offset carbon footprint. Same should be true when I fill up my gas tank or fly on a plane (not the thousands part). These things should have a real cost that offsets the carbon impact.

  • But nobody in the developed world. It's less than 10% of the average lifetime CO2 footprint for an American, and most of us will never go on one of these trips in our lifetimes. You can make a much bigger impact on your carbon footprint by living in a well-insulated home close to your workplace.

  • Step 1: find a reason regulations and crony capitalism are corrupting true-unbridled-capitalism Step 2: Buy some aerospace stock Step 3: post about how regulations and high taxes are the real problem Step 4: watch the world burn with a smug sense of self satisfaction that you were right all along, crony capitalism was the problem and if they'd just listen to the anarchy-capitalist libertarians we'd all be living in a carbon capture and storage utopia sipping a synthetic pina colada on a space station surrou
  • "Creation of scientific and technical jobs" is not a reason to launch people into space if there are no other positives (which there may certainly be). This is akin to saying we should keep mining coal because how else will coal miners have jobs. Now if those scientific and technical jobs have other merit, great, but "jobs" in and of themselves do not justify the existence of an industry.

  • When you start handling stats like this you end up with using the results wrong.

    An interesting stat is the average family in North American used to have 2.5 kids.

    Based on this method of handling stats I need to ask where all the 1/2 kids are.

    What an absolutely fucking miserable article.

  • They also don't mention that one does not take a space flight every day - it is a once in a lifetime event for most of those who do it. And if the argument is that one should not do things that increase the carbon footprint, then perhaps we should stop engaging in all sports, vacations, and pursuit of the arts because they all produce carbon unnecessarily. Finally, space flight is an immature technology. It is reasonable to expect that eventually we will have better methods (e.g. https://www.psatellite.com/ [psatellite.com]
  • ... that don't require setting a skyrocket off under it. Solutions can be found in science fiction novels, if anyone cares to look. Plus the cost/kg is much lower, if we can build something like the Loftstrom launch loop or a beanstalk in a geosynch orbit.

    Note: When you hear people railing against the global 1% then you should take note. To be in that 1% requires an individual annual income of only $35,000. That's significantly less than the median income in the USA.

    Opinion:

    About one billion individuals emit less than one tonne [of CO2] per person per year. Over their lifetime, this group of one billion individuals does not emit more than 75 tonnes of carbon per person.

    That means that one person in seven uses less than 6 pounds/3 kilos of dry firewood, charcoal, or other fuel as an energy source per day. If that's true, and it probably isn't, that is a problem that needs to be addressed. That level of energy poverty is NOT an aspirational goal.

  • his is like that famed19th century prediction that by the time the twentieth century rolls around, transportation in New York City will become impossible because the city will be neck deep in horseshit.

    That last phrase richly describes this analysis. It costs a lot in carbon terms to send one astronaut to orbit using RP-1 kerosene, but by the time large numbers of people get sent up, this will be replaced by nonpolluting hydrogen-oxygen. In fact, this is what the much-giggled-at Blue Origin suborbital craft

    Never-mind that Bezo's rocket runs on hydrogen & oxygen, thus spewing forth exactly 0 milligrams of carbon per billion passengers...
  • I'm no Bezos fanboy, but give the guy a break (and at least PRETEND to have some basic scientific knowledge when reporting on spaceflight matters). New Shepherd burns Hydrogen and Oxygen, so pure, essentially distilled, water is the exhaust and Carbon is nowhere in the equation. Also, the rocket is fully-reusable, so it's not even throwing stuff away or requiring the fabrication of big new parts, with any associated manufacturing burdens. In fact, the booster even flies back to the launch pad, so there's no

  • There are f'ing 8 billion people. And we are worrying about 1 per launch?

Every nonzero finite dimensional inner product space has an orthonormal basis. It makes sense, when you don't think about it.
