Percentage CO2 emission From Air
2.5 percent
Over all, air travel accounts for about 2.5 percent of global carbon dioxide emissions — a far smaller share than emissions from passenger cars or power plants.
The findings put pressure on airline regulators to take stronger action to fight climate change as they prepare for a summit next week.
Greenhouse gas emissions from commercial air travel are growing at a faster clip than predicted in previous, already dire, projections, according to new research — putting pressure on airline regulators to take stronger action as they prepare for a summit next week.
The United Nations aviation body forecasts that airplane emissions of carbon dioxide, a major greenhouse gas, will reach just over 900 million metric tons in 2018, and then triple by 2050.
But the new research, from the International Council on Clean Transportation, found that emissions from global air travel may be increasing more than 1.5 times as fast as the U.N. estimate. The researchers analyzed nearly 40 million flights around the world last year.
“Airlines, for all intents and purposes, are becoming more fuel efficient. But we’re seeing demand outstrip any of that,” said Brandon Graver, who led the new study. “The climate challenge for aviation is worse than anyone expected.”
Airlines in recent years have invested in lighter, more fuel-efficient aircraft, and have explored powering their planes with biofuel.
Over all, air travel accounts for about 2.5 percent of global carbon dioxide emissions — a far smaller share than emissions from passenger cars or power plants. Still, one study found that the rapid growth in plane emissions could mean that by 2050, aviation could take up a quarter of the world’s “carbon budget,” or the amount of carbon dioxide emissions permitted to keep global temperature rise to within 1.5 degrees Celsius above preindustrial levels.
The decision by Greta Thunberg, a young climate activist, to sail across the Atlantic rather than travel by air ahead of her speech at the United Nations next week, has refocused attention on aviation’s role in causing climate change and its consequences, including sea-level rise and more intense heat waves, hurricanes, flooding and drought.
Climate protesters have said they plan to gather in Montreal next week, where airline regulators are set to hold their own summit.
William Raillant-Clark, a spokesman for the U.N. aviation body, stood by its emissions projection, which he said was “the most up-to-date” and provided “a clear picture on the future environmental trends.” He added that the group “endorses and welcomes wholeheartedly” calls for the aviation industry to address climate change with greater urgency.
Underlying the growth in aviation emissions is the rapid expansion of air travel worldwide, propelled by a proliferation of low-cost airlines and a booming tourism industry catering to a growing middle class.
A separate study released this week by the industry group Airports Council International found that the world’s fastest-growing airports were in emerging economies; 12 of the top 30 were in either China or India.
Still, the new data from the clean transportation council found that flights from airports in the United States were responsible for almost one quarter of global passenger flight-related carbon dioxide emissions. China was the next biggest source of passenger aviation emissions, followed by the United Kingdom, Japan and Germany; the lowest-income countries that contain half the world’s population accounted for only 10 percent of all emissions.
The study underscored the heavy carbon-dioxide footprint of domestic flights, often left out of negotiations over global emissions-reduction targets. Domestic travel accounted for a large majority of departures in countries including the United States, China, Indonesia, Brazil and Australia.
Governments have pledged to take major steps to improve fuel economy in their routes and fleets. Under a plan adopted by the U.N. body, the International Civil Aviation Organization, three years ago, airlines will start to voluntarily offset most of the growth in their carbon dioxide emissions beginning in 2020. Carbon offsets compensate for emissions by canceling out greenhouse gas emissions elsewhere in the world. (For example, the offset may involve paying for renewable energy or other programs designed to reduce emissions.)
Some governments have suggested going further. In Germany, the Green Party has suggested banning domestic air travel altogether to force Germans to travel by train, which pollutes less.
“At a time when students are going on climate strikes around the world, this will really put pressure on the aviation industry to be much more ambitious,” said Annie Petsonk, international counsel for the Environmental Defense Fund. “They’re beginning to understand that for most people who fly, aviation is the biggest part of their personal carbon footprint.”

Cost of shuttle launch
$450 million
The average cost to launch a Space Shuttle is about $450 million per mission.
How much does space travel cost?
With the rise of private spaceflight, costs are falling — but leaving the planet is still far from cheap.
The SpaceX Falcon Heavy rocket costs an estimated $90 million per launch
Spaceflight has traditionally been a government-led activity — and it's never been cheap. But the stratospheric cost of putting people and payloads into space is finally starting to fall, thanks in part to the rise of SpaceX and other private spaceflight companies.
Here’s a look at what it costs to go to space, whether it’s another satellite that needs to be placed in orbit or an adventurous billionaire looking for a joyride around the moon.
Sending up a satellite
Using its 230-foot-tall Falcon 9, SpaceX charges $62 million to send into orbit commercial satellites weighing up to 50,000 pounds. The closest American competitor is the United Launch Alliance Atlas V, which starts at $73 million for a 41,000-pound payload.
Those are just starting prices; government agencies typically pay more for a long list of extra services. The Air Force, for example, is paying SpaceX $96.5 million to launch a GPS satellite in 2019
Flying to the International Space Station
Since NASA mothballed its space shuttles in 2011, NASA has relied on the Russian Soyuz spacecraft to get astronauts to the ISS. Russia has been steadily raising the price of Soyuz seats, reaching $82 million each in 2015. The agency last purchased Soyuz seats for $75 million apiece in 2017.
NASA hopes to end its reliance on Russia in 2019, when SpaceX's Crew Dragon and Boeing's Starliner capsules begin “taxi” flights to the ISS. Seats on those spacecraft are expected to cost about $58 million.

A ride in Virgin Galactic's Spaceship Two costs riders about $250,000 per trip.
Jeff Bezos’ rocket company, Blue Origin, plans something similar — sending space tourists on brief suborbital flights using its New Shepard rocket system. The company has yet to set ticket prices or say when paid flights might begin.
Virgin Galactic and Blue Origin passengers will join the fewer than a dozen private citizens who have funded their own trips into space. From 2001 to 2009, the Vienna, Virginia-based firm Space Adventures worked with Russia’s space agency to send eight people to the ISS on flights lasting 10 or more days.
The world's first private astronaut, a wealthy American engineer named Dennis Tito, reportedly paid $20 million to spend eight days in space in 2001. More recently, Guy Laliberté, the co-founder of Cirque du Soleil, shelled out $35 million for an ISS trip in 2009. Space Adventures still advertises Soyuz flights and plans to start booking trips to the ISS aboard Boeing’s Starliner.
In September 2018, SpaceX CEO Elon Musk announced that Japanese billionaire Yusaku Maezawa would ride the company’s yet-to-be-built Big Falcon Rocket on a trip around the moon. Neither Musk nor Maezawa, who said he would take along seven artists, would discuss the mission’s cost.
What about other rockets?
Small satellites may qualify for a free ride to space through NASA’s Educational Launch of Nanosatellites program, which helps universities and research groups fly standardized satellites called CubeSats aboard rockets as secondary payloads.
If your satellite can’t hitch a free ride, you can book a NASA sounding rocket to the edge of space for as little as $1 million. For orbital flights of payloads weighing less than 500 pounds, Los Angeles-based Rocket Lab offers launches of its Electron rocket from New Zealand for about $5 million.
From there, the price goes up steeply. Northrop Grumman's Pegasus rocket, which is air-launched from the belly of a jumbo jet, can place 1,000 pounds in orbit for about $40 million. Stratolaunch, a new venture bankrolled by Microsoft co-founder Paul Allen, plans to launch Pegasus rockets from its own colossal airplane before offering an expanded line of rockets capable of carrying up to 13,000 pounds. The company has yet to disclose prices.
NASA is developing its Space Launch System, which will carry astronauts to the moon and Mars. The rocket’s per-launch cost has not been disclosed, but the agency now spends at least $2 billion per year on the project. The maiden flight isn’t expected until 2020.
