Electric car battery production causes less CO2 emissions than once thought: study

The classic anti-Tesla argument alleging that CO2 emissions from battery production negates the positive environmental impact of electric vehicles may have been disproven for good. This comes after the IVL Swedish Environmental Research Institute, one of the firms responsible for the original anti-EV claim, completed a new study that showed a much different result.

The IVL conducted a study in 2017 which revealed that the emissions from the production of lithium-ion batteries was responsible for a large amount of CO2, making the purchase of an electric car practically pointless in an environmental sense. The 2017 study claimed that the production of EV batteries emits around 150 and 200 kg of CO2 per kWh. However, a new study, summarized in a recent press release from IVL, showed the amount of CO2 emissions from battery production has been reduced to between 61 and 106 kg of CO2 equivalent per kWh.

Erik Emilsson, a researcher for the IVL stated that “emissions are lower now is mainly due to the fact that battery factories have been scaled up and are running at full capacity, which makes them more efficient per unit produced. We have also taken into account the possibility of using electricity that is virtually fossil-free in several of the production stages.”

The IVL believes this reduced number can get even lower with the development of more sustainable techniques during the different states of the electric car life cycle. For example, some Tesla Superchargers and other EV chargers are still powered by a CO2-emitting resource. Tesla CEO Elon Musk stated in October 2019 that the company’s objective is to move away from this “as fast as possible” by adding solar panels to Supercharger stations.

Musk is not the only automotive executive looking to move away from coal-powered electric vehicle charging stations. Volkswagen Auto Group CEO Herbert Diess, who thinks highly of Musk’s vision of a sustainable future, has also stated that it is imperative for manufacturers of charging stations to make their products CO2-free.

“Coal and CO2-free electricity is a must for electric cars,” he said at a Volkswagen event in March 2019. We call on industry, politics, and society to jointly set all levers in motion to help electric-mobility achieve a breakthrough.”

The development of cleaner manufacturing doesn’t stop at the factory, however. Mining the materials for vehicle batteries is also a contributor to the negative environmental impact of electric cars. Mining can have a significant environmental and social impact. Batteries contain metals such as lithium, cobalt, nickel, and manganese.

More information is needed on the environmental impact of metal supply chains as well as better traceability processes if we are to ensure sustainable production across the entire chain,” Emilsson said. The development of new batteries is moving away from the most damaging metals, especially cobalt, an element that will be replaced in batteries by utilizing more nickel. Among those leading the pack in these efforts is Tesla as well.

The advancement in the production of batteries and electric vehicles as a whole assists in the fight against global climate issues. Technology continues to improve and the use of environmentally detrimental materials will likely be phased out as knowledge of battery systems increases. Many forget that the electric car industry is very new, especially compared to its petrol-based counterpart that has been around since the late 1800s.

Electric cars will only continue to advance in every stage, from mining to production, to driving, to recycling. The news from IVL that emissions during the production of these sustainable vehicles have decreased significantly shows the industry continues to grow and do what it was created to accomplish: save our planet from environmental catastrophe from the use of gas-powered vehicles that contribute to the steady increase in CO2 into our atmosphere.

Cybertruck production at Giga Texas is showing its first visible recovery since Tesla sued a supplier last month over withheld manufacturing tooling.

Aerial observer Joe Tegtmeyer flew over the Austin factory Wednesday morning and counted roughly 100 or more Cybertrucks filling the outbound lot, a sharp jump from the thin numbers seen in recent weeks. The flyover came a day after a judge granted Tesla a temporary restraining order against Angstrom Automotive Group, the parts supplier at the center of the dispute.

Tesla filed an emergency lawsuit in late July after Angstrom told the automaker it planned to close the Troy, Texas facility where Tesla’s die-cast tools, trim dies and other Cybertruck stamping equipment were housed. According to Tesla’s complaint, a shipment of 700 finished parts never left the building, and when Tesla sent representatives to retrieve its equipment, accompanied by law enforcement, they were turned away. Angstrom allegedly then asked for an extra $250,000 a week to keep operating, which Tesla’s filing described as holding its own property for ransom.

The restraining order gives Tesla immediate right of entry to Angstrom’s facility to recover the tooling. It is temporary, with a fuller hearing still to come, but the speed of Wednesday’s rebound suggests the Angstrom shortage was indeed the main bottleneck limiting Cybertruck output. Outbound lot counts are an imperfect measure of actual production, since finished trucks can sit for days before shipping, but a lot that full after a lean stretch is a meaningful signal.

Cybertruck output at Giga Texas has fluctuated all year as Tesla worked through supply issues and introduced new trims, including a cheaper Dual Motor AWD version that drew strong early demand.

Space finally faced the people living next to its next Terafab mega-project

SpaceX confirmed Terafab’s Grimes County site is locked in, with construction starting within months.

SpaceX and Terafab representatives sat across from Grimes County residents for the first time on Wednesday, telling a packed Commissioners Court room that the $55 billion chip manufacturing project is now a done deal at the Gibbons Creek Reservoir site.

The meeting followed a $10 million check SpaceX sent the county earlier this week, satisfying a payment deadline built into the tax abatement agreement both sides signed in June. Elon Musk shared a post on X confirming the payment, and County Judge Joe Fauth told the San Antonio Express-News his office deposited the check after it beat its deadline.

Wednesday’s session, first reported by KBTX, moved the project from paperwork to construction. Terafab representative Riley Trennell told residents the JETI tax break agreements with Iola ISD and Anderson-Shiro CISD are signed and active, and that civil work and foundation prep are starting almost immediately. Renderings of the facility could be released within days, he said, with construction beginning within months.

Elon Musk launches TERAFAB: The $25B Tesla-SpaceXAI chip factory that will rewire the AI industry

Musk first announced Terafab in March as a joint venture between Tesla, SpaceX and xAI aimed at producing over a terawatt of AI compute annually, an amount that dwarfs the roughly 20 gigawatts the entire global chip industry produces today. Intel joined as a manufacturing partner in April. Musk has said the project needed its own day in the spotlight rather than being squeezed into an earnings call, and for months the Grimes County site remained unconfirmed even as reporting pointed there.

SpaceX attorney Buck Brannon used Wednesday’s meeting to note that the company’s abatement is roughly 78 percent, not the 100 percent some earlier reports suggested. In exchange, SpaceX will pay Grimes County a fixed $20 million a year for 35 years, a total of $710 million, which Brannon said exceeds the $14 million Tesla paid Travis County in 2025.

SpaceX also addressed environmental concerns that have followed the project since Musk’s Terafab partnership with Intel was announced. Representatives said Terafab will not raise electric bills for other ratepayers, will not deplete local water supplies and will not draw down the Navasota River. SpaceX confirmed it owns the Navasota River pumping station, which it plans to use to divert stormwater into the Gibbons Creek Reservoir, and said it will build its own natural gas plants to power the facility rather than pulling from the ERCOT grid.

Grimes County commissioners also approved an addendum letting county employees use ten approved AI chatbots for work, including Grok.

SpaceX has solved Starship’s biggest challenge, Elon Musk says

Elon Musk has declared that SpaceX has effectively solved one of Starship’s most persistent engineering challenges: the reliability of its heat shield tiles.

During the company’s first-ever Earnings Call, the SpaceX CEO stated:

“I don’t want to jinx it or anything, but I think I would call the heat shield problem solved at this point. All indications from data and visual inspection is we have solved it. That doesn’t mean we won’t make improvements, but we do not see any technical obstacles to achieving rapid reusability at this point.”

Starship’s heat shield consists of roughly 18,000 hexagonal ceramic tiles covering the windward side of the upper stage. These tiles form the thermal protection system that shields the vehicle’s stainless-steel structure from the extreme heat of atmospheric reentry.

During descent, atmospheric friction generates temperatures exceeding several thousand degrees Celsius and creates plasma flows capable of melting unprotected metal. The tiles absorb, radiate, and insulate against this energy, allowing the vehicle to survive and potentially fly again. Without a durable heat shield, full and rapid reusability, the cornerstone of Starship’s design for frequent launches, satellite deployments, and deep-space missions, would remain impossible.

The tiles have long been a source of difficulty. On earlier test flights, a significant number of tiles detached during ascent due to vibration, aerodynamic loads, and imperfect attachment methods using pins and adhesives. Gaps between tiles allowed hot plasma to infiltrate, causing secondary damage and hot spots on the underlying structure.

These issues echoed challenges faced by NASA’s Space Shuttle, whose ceramic tiles required extensive, labor-intensive inspections and replacements between missions, preventing rapid turnaround. SpaceX has iteratively improved materials, standardized tile shapes, refined attachment techniques, added secondary ablative layers, and tested sealing methods such as “crunch wrap” felt to close gaps.

Progress was visible across Flights 10–12, with steadily better tile retention, yet questions remained about whether the system could support the minimal-refurbishment goal of rapid reuse.

Flight 13 on July 24 provided the decisive evidence. Ship 40 flew a deliberately more demanding profile with higher dynamic pressure to stress the heat shield beyond typical operational loads. It successfully deployed 20 operational Starlink V3 satellites, the first such payload on a Starship mission, performed an in-space Raptor engine relight, and executed a controlled reentry.

Cameras on six of the satellites and onboard sensors captured extensive imagery and data of the shield throughout the flight. The ship then achieved its softest splashdown to date in the Indian Ocean, remaining intact and floating rather than breaking apart or exploding as on prior missions. This allowed drone inspections and continuous telemetry of the heat shield in near-real time.

Post-flight analysis showed the majority of tiles remaining attached with only minor damage and limited plasma streaking at seams. Musk noted that the mission delivered “all the heat shield data we needed and then some.” Combined with visual inspections, these results underpinned his subsequent assessment that the core technical barriers to rapid reusability have been cleared. While refinements will continue, Flight 13 marked a pivotal step toward Starship’s operational future.
