Those old enough to remember road trips in the days before handheld video games, televisions mounted in headrests, and smartphones will recall the myriad ways in which we entertained ourselves as the miles went by. Some games involved punching each other when a (gas-powered) Volkswagen Beetle was spotted. Others required finding out-of-state license plates. And then there were those about numbers.

Today’s numbers from the road are a bit less fun. Globally, 14 percent of greenhouse gas emissions originate from the transportation sector—and that jumps to 27 percent in the United States. Cars aren’t the only culprits. The aviation industry is also concerned about its share of carbon dioxide (CO2) going into the atmosphere. On our way to a sustainable, carbon-neutral future, bypassing such pollution is a must.

The ACCJ Journal spoke with companies in the automotive and aerospace sectors to take the pulse of transportation and find out where future journeys might take us.

Hit the Road

Everywhere you turn, there’s a car. And most are still burning gasoline. But as climate change becomes a more urgent problem, the tide is turning. The compound annual growth rate of the electric vehicle (EV) market is now at 24.8 percent, and sales are projected to reach $980 billion dollars by 2028, up from $185 billion in 2021.

The move by California to ban the sale of new gas-powered cars and light trucks by 2035 is sure to accelerate that change, at least locally.

While it might feel as if electric cars are a rather new invention, they’ve been around for a long time. The first was Scottish inventor Robert Anderson’s motorized carriage around 1832, more than 50 years before German engineer Karl Benz rolled out the first gas-powered car.

So, what’s old is new again as EVs drive their way to the head of the pack and cut greenhouse gas emissions in the process.

Tesla may be the first brand that comes to mind when asked to name an EV, but there are many options on the road today, ranging from the very affordable Nissan Leaf to GMC’s powerful-but-expensive Hummer EV pickup. Chevy has even announced an all-electric Corvette. What would Florence Jean “Flo” Castleberry have to say about that? These are all changing the way we think about automobiles.

“Similar to the way the smartphone turbocharged the use of the internet, pushed it to become fully mobile, and instigated many new services—and industries—EVs are digitally transforming the transportation industry as a conduit for new mobility technologies that go beyond simply using an electric power source,” explained Karma Automotive LLC’s Chris Sachno, who will speak about electrifying mobility at an event hosted by the American Chamber of Commerce in Japan Information, Communications, and Technology Committee on October 6.

The senior vice president for e‑mobility, cloud services, and innovation said this is summarized by the CASE model of automotive technology megatrends. An acronym for connected services, autonomous vehicles, shared mobility, and electrification technologies, CASE is providing a superior user experience with groundbreaking technologies, Sachno explained. “There are economic benefits, as well, such as lower total cost of ownership and reduced emissions, which encourage economic activity within communities,” he added.

Karma has developed a commercial solution called Powered by Karma which enables existing internal combustion engine (ICE) vehicles to be converted to electric powertrains.

“This dramatically reduces the complexity of the drivetrain by 90 percent, from more than 1,000 components to fewer than 100,” Sachno said. “Installing an electric powertrain into an existing commercial vehicle also extends the life of the vehicle’s other parts, such as the body, chassis, brakes, and interior. This reduces the emissions created during the production of a new vehicle, or from scrapping or recycling the old vehicle.”

The Powered by Karma electrification solution, which utilizes the company’s OEM experience and automotive grade technology in providing top-quality engineering, design, electrification, and contract manufacturing, delivers a total cost of ownership reduction of up to 48 percent.

“We believe this provides a unique proposition for the commercial vehicle space by offering electrification solutions for existing vehicles, rather than relying on the replacement of existing ICE vehicles. Substitution will take considerable time, especially given the long lifetime of commercial vehicles,” Sachno said.

The Irvine, California-based EV startup also designs and manufactures its own vehicles. The Revero GT is powered by dual electric motors that offer extended range and embody Karma’s goal of offering leading technology with a luxury experience. And last year, Karma introduced the 536-horsepower GS-6, which Sachno said “looks amazing, is incredibly fun to drive, and is packed full of cutting-edge technology.”

While building such vehicles, Karma is dedicated to sustainability and, in 2021, joined The Climate Pledge, which was co-founded in 2019 by Global Optimism, and ACCJ corporate sustaining member Amazon. As a signatory, Karma has committed to become net-zero by 2040.

“This commitment encompasses our production facility, supply chain partners, and product lineup, which includes vehicles powered both by hybrid and pure electric powertrains and propulsion systems,” Sachno explained. “Karma continues to align with partners that share the same philosophy on protecting the environment and investing in research and development projects that have a positive effect on the planet. We look forward to collaborating with other Climate Pledge signatories on research and development of green technologies in the automotive space to advance and attain the goal of becoming net carbon neutral.”

Take Flight

The ground can only get you so far. Air travel is essential to life in the 21st century. In our tightly knit, global community, the movement of people and goods is key to a healthy economy, quality of life, and support of those in need following disasters and during humanitarian crises.

The coronavirus pandemic may have curtailed travel, but the statistics from 2019, the last year before the appearance of Covid-19, demonstrate the importance of air travel. In that year, according to the Geneva-based Air Transport Action Group, 4.5 billion people flew, $7 trillion in goods were exchanged, and the aviation industry supported 87.7 million jobs.

The environmental impact of aerospace will again increase, what with global travel now recovering as border restrictions and testing requirements are lifted. Japan, one of the only countries still limiting the number of tourists it allows in, announced on September 23 that it will fully reopen on October 11.

In 2019, the airline industry generated 900 million tons of carbon emissions, accounting for 12 percent of transportation-related emissions and 2.6 percent of all emissions globally.

Two companies with which The ACCJ Journal spoke explained the steps they are taking to reduce their carbon footprint.

Boeing, also an ACCJ corporate sustaining member, designs and manufactures some of the most widely used passenger planes. It put additional emphasis on sustainability in 2020 by naming a chief sustainability officer, reviewing the composition of its board-level subcommittee, and explicitly incorporating sustainable aerospace into the company’s values and strategic objectives.

There are four pillars to Boeing’s sustainability activities:

• People
• Products and services
• Operations
• Communities

“Today, all our stakeholders are increasingly concerned about sustainability and, specifically, the environmental impact of aerospace,” said Will Shaffer, president of Boeing Japan and an ACCJ governor. “We recognize climate change-driven risks and the need to decarbonize aerospace for sustained long-term growth, as well as stakeholder trust and preference.”

Everything for Zero

Boeing’s vision for future flight is embodied in the company’s Everything for Zero initiative, which comprises four strategies to get to zero-climate-impact aviation:

• Fleet renewal: replacing older models with more efficient ones
• Operational efficiency: leveraging data, digital tools, and modifications to reduce emissions
• Renewable energy transition: utilizing sustainable aviation fuel (SAF), renewable electricity, and green hydrogen
• Advanced technologies: intersecting fuel sources with advanced-technology flying machines

Also, part of the initiative is verified offsets—midterm, market-based solutions for matters which cannot yet be sufficiently addressed.

“Boeing has invested more than $60 billion over the past 10 years to improve sustainable product lifecycle, including innovative technologies such as the digital thread, carbon composite materials, and advanced high-bypass-ratio engine designs,” explained Shaffer. “Other aerodynamic improvements include a natural laminar flow that reduces drag to improve environmental efficiency.”

These efforts have led to planes which provide significant efficiency gains. Each generation reduces fuel use and emissions 15–25 percent, as demonstrated by the Boeing 777-9, which has 25-percent lower CO2 emissions compared with previous planes. The 777-9 is slated to enter service in 2025.

Airlines flying Boeing planes are taking advantage of these new technologies as they move along their routes to net-zero.

“Many customers have accelerated the retirement of older airplanes during the pandemic to optimize their fleets with the latest, most-efficient models,” Shaffer said. “Our latest Commercial Market Outlook forecasts that 49 percent of the 41,170 planes needed will be fleet replacements. Boeing will continue to invest in efficiencies that reduce fuel use and carbon emissions.”

Given that those airplanes will use current propulsion technology and be flying for the next 20–30 years, SAF will play a big part in realizing the aviation industry’s ambitious goal of zero carbon by 2050. Boeing and the world’s airlines recognize the importance of increasing SAF production and promoting its use. In fact, this year Boeing procured 2 million gallons of SAF for its own operations at its factories in the United States. And in Japan, it recently joined ACT for SKY, a voluntary organization of companies from the airline, engineering, and biofuel industries, among others, that works to commercialize, promote and expand the use of Japan-produced SAF.

Sustainable Flight Challenge

Fellow ACCJ corporate sustaining member Delta Air Lines, Inc. is one Boeing customer that is assisting with the development of new technologies and solutions.

In April, Delta’s most fuel-efficient plane at the time, the Boeing 737-900ER, made a flight powered by a fuel blend that included 400 gallons of SAF. It was part of the Sustainable Flight Challenge hosted by the SkyTeam Alliance, a group of 18 airlines that operates more than 10,000 daily flights over 1,062 destinations in 170-plus countries. The flight was part of Delta’s ongoing efforts to reduce its carbon footprint—a goal to which the airline is devoting significant resources.

Delta now has even more fuel-efficient planes in its updated fleet, including the Airbus A350-900 and the A330-900 neo.

“In 2022 alone, we are expecting to have reduced fuel consumption by more than 10 million gallons through operations and fleet modifications, including reducing aircraft weight, modifying landing approaches, and optimizing flight speed,” according to Victor Osumi, managing director and president of the Atlanta-headquartered airline’s operations in Japan.

“We’re also funding top minds to accelerate new innovations through our pension fund’s co-investment with the TPG Rise Climate Fund.” This fund opened in early 2021 and closed its inaugural fundraising in April of this year, having brought in $7.3 billion. The primary climate investing strategy of global alternative asset manager TPG, it focuses on five climate sub-sectors:

• Clean energy
• Enabling solutions
• Decarbonized transport
• Greening industrials
• Agriculture and natural solutions

To support the exchange of knowledge and generate investment opportunities, TPG formed the Rise Climate Coalition. Some 28 companies, including Boeing, are part of the alliance, and Delta announced its involvement in March. Delta Vice President of Sustainability Amelia DeLuca said in the announcement that “investing in TPG Rise Climate is the next step … as we work to decarbonize our operations while supporting promising solutions for the future.” All these efforts are important parts of how Delta is pushing the industry forward.

“As we reshape the fundamentals of aviation, we are dedicated intently across these areas to making immediate progress and to investing wisely in disruptive solutions,” explained Osumi, who is also an ACCJ governor. “A portfolio of short-, medium-, and long-term actions across the industry are essential to achieving net-zero aviation.”

Start Me Up

Electricity could be one solution. Might it serve as a power source for aircraft, as it now widely does for cars? Osumi said that, as of now, electric-powered aircraft appear to be an option for smaller, shorter-haul flights. “But as investments and innovations continue, that could evolve,” he added. “We believe that there are many paths that could help accelerate us to a more sustainable future.

Renewable electricity is part of Boeing’s Everything for Zero initiative. The company and its joint venture partner Wisk Aero LLC announced on September 20 a roadmap for the deployment of an electric vertical take-off and landing (eVTOL) solution for urban commuters.

“Boeing and Wisk are developing a two-passenger eVTOL air taxi, which has flown more than 1,500 successful test flights since 2017,” explained Shaffer. “Wisk’s sixth-generation eVTOL aircraft will represent a first-ever candidate for the certification of autonomous, all-electric, passenger-carrying aircraft in the United States.”

And in January, GE Aviation announced the selection of Boeing to support the flight tests of its hybrid electric propulsion system—a big step forward in exploring ways to reduce carbon emissions.

Boeing has been exploring and developing concepts for advanced aircraft that can meet specific energy-efficiency, environmental, and operational goals.

Hydrogen High

Given the success of transitioning cars to electricity, it’s no surprise that the same ideas are being applied to aircraft. But what about the universe’s most abundant chemical substance? Could hydrogen one day be used to zip air passengers around the globe?

Osumi said that hydrogen is one of the options being explored by Delta for next-generation aviation. The company has partnered with Airbus to study hydrogen-powered aircraft as well as the ecosystem required at airports and beyond as a way to reduce aviation emissions exponentially.

Boeing is also innovating with hydrogen. Shaffer noted that they’ve been developing hydrogen and fuel cell applications on board aircraft for more than 15 years, carrying out six hydrogen technology demonstrations with crewed and uncrewed aircraft using hydrogen fuel cells and hydrogen combustion engines.

“We benefit from green hydrogen for any version of the future,” he said. “Green hydrogen is used to produce SAF and it has the potential to be used in future propulsion systems, when the technology is ready.”

A new Japan Research and Technology Center, focused on sustainability, that opened in August is just one of the investments Boeing is making to find sustainable solutions in Japan. As part of this, Boeing and its Japanese partners will pursue research into zero climate impact aviation under an agreement with the Ministry of Economy, Trade and Industry. In addition, it also announced a partnership with Mitsubishi Heavy Industries in July that will involve the study of hydrogen as well as other sustainable technologies.

New Heights

Osumi said he and Delta look forward to fostering collaboration with the industry, academia, and startups to accelerate the sustainable future of flight. “We’re optimistic about early-stage companies pushing the boundaries with futurist thinking on aircraft, propulsion, and more.

“And we’ve proven that the infrastructure exists to make sustainable aviation fuel, or SAF, accessible to every major airport on the East Coast by leveraging our partnership with Colonial Pipeline.” This company operates the largest pipeline system for refined oil products in the United States.

With the evolution of next-generation technologies, he expects to see new designs for planes and a completely transformed client perception. “Even now, on Delta planes, the customer experience is beginning to look more sustainable, with refreshed onboard product offerings such as artisan-made amenity kits, recycled bedding, reusable and biodegradable service ware, and premium canned wine.” Together, these products will reduce onboard single-use plastic consumption by approximately 4.9 million pounds per year—roughly the weight of 1,500 standard-sized cars—and significantly increase Delta’s support of minority- and women-run businesses.

Boeing aims for much the same.

“Our common goal is to have zero impact on our planet while maintaining and growing the societal benefits of air transportation,” concluded Shaffer. “To ensure the benefits of aerospace remain available for generations to come, we have work to do. We’ve made great strides since the beginning of the jet age, but our greatest accomplishments are yet to come. We believe the future of flight will take ‘everything for zero.’”
