Kestrix is taking thermal imaging to city scale, using drones and AI to map heat loss across Europe's ageing homes - one infrared pixel at a time.
Founded by Oxford alumni in 2022, the startup is tackling a massive climate blind spot: energy-inefficient buildings.
With 100m European homes needing retrofits to hit 2050 net zero targets, Kestrix's tech pinpoints where heat escapes, guides retrofit strategies, and verifies energy gains after intervention.
The company's solution is elegantly simple - fly a drone, scan a block, run it through AI, and produce an actionable heat-loss map.
But the implications are vast. Municipalities get planning-grade data, housing providers save time and cash, and Kestrix unlocks a scalable business in decarbonising real estate.
From heating to cooling, this platform's utility spans geographies, seasons, and regulation regimes.
With Pi Labs as lead investor and strong momentum in city- and nation-led climate planning, Kestrix is riding a wave of urgency.
Its team blends technical skill with operational tenacity, offering a high-leverage tool at exactly the right time.
In the race to retrofit, Kestrix could become the thermal twin of every building in Europe.

How to Stay Compliant Amid Amazon's Growing Focus on Allergen Labeling
Selling on Amazon used to be about standing out. Now it's equally about staying compliant. As regulations tighten across global markets, Amazon is placing greater emphasis on product safety, and allergen labeling has moved to the front of the line. Undeclared allergens can trigger life-threatening reactions for consumers. This is why Amazon now demands clear, verified allergen disclosures across many product categories, from supplements and skincare to packaged foods. Sellers who overlook these rules risk listing delays, account suspensions, or far more serious legal trouble. Here, we break down Amazon's evolving allergen compliance requirements, the products affected, which allergens must be disclosed, and how sellers can meet Amazon's demands before risking costly disruptions. Allergen compliance on Amazon is no longer optional or negotiable. The platform's increasing focus reflects broader regulatory and public health concerns worldwide. Food allergies are rising globally. For sensitive individuals, even trace exposure to allergens can cause severe reactions. Regulatory agencies expect retailers—online or brick-and-mortar—to ensure proper disclosures that protect consumers. Amazon's allergen rules are designed to reduce these safety risks. Amazon operates internationally and must comply with laws set by agencies like the FDA (U.S.), EFSA (EU), Health Canada, and others. As these regulators increase enforcement on allergen mislabeling, Amazon proactively adjusts its own compliance policies to stay aligned. When undeclared allergens trigger safety incidents, both the seller and Amazon may face regulatory investigations or lawsuits. Strengthening allergen compliance helps Amazon reduce legal exposure while preserving consumer trust. Allergen labeling requirements don't apply to every category equally. Amazon's policies focus on high-risk product groups that pose ingestion or dermal contact risks. Supplements often contain ingredients derived from major allergens like soy, shellfish, dairy, or nuts. Amazon requires sellers to fully disclose all potential allergens both on the product label and within Amazon's listing backend. While applied externally, many skincare products contain ingredients that may trigger allergic skin reactions. Formulations using nut oils, wheat proteins, soy extracts, or egg derivatives may fall under allergen disclosure policies. Amazon's food and grocery listings demand full allergen labeling in line with regional food safety laws. This includes both intentional ingredients and possible cross-contamination risks during manufacturing. Amazon's allergen requirements reflect regional regulations that differ by country. Sellers listing products across multiple Amazon marketplaces must comply with each market's allergen lists. In the United States, Amazon sellers must disclose the following major allergens: Milk Eggs Fish Crustacean shellfish Tree nuts Peanuts Wheat Soybeans Sesame (officially added in 2023) European regulations expand this list further. In the EU and UK, sellers must disclose 14 allergens, which include: Gluten-containing grains (wheat, barley, rye, oats) Lupin Celery Mustard Sulfites (above specific thresholds) Mollusks (alongside crustaceans) Other markets have unique allergen lists. For example, Canada includes sesame, mustard, and sulfites under its priority allergen list, while Japan has its own set of required disclosures. Sellers must verify requirements for each Amazon marketplace they serve. Amazon enforces allergen compliance through both product documentation and its listing creation process. Product labels must include visible allergen declarations following each market's regulatory format. In many regions, allergens must be bolded or listed in separate 'Contains' statements to ensure clarity for consumers. Amazon may require sellers to submit certificates of analysis (COAs), ingredient specifications, and supplier documentation verifying allergen content or absence. Some sellers may also need manufacturing allergen control plans if requested during compliance reviews. During listing creation, Amazon's product attribute forms often include mandatory allergen declaration fields. Sellers must complete these fields truthfully to ensure alignment between backend data and physical labeling. Inaccurate or incomplete allergen disclosures expose sellers to serious consequences, both within Amazon's platform and under local regulatory laws. Amazon may block new product listings or suspend existing ASINs if allergen data is missing, inconsistent, or conflicts with submitted documentation. Resubmissions can delay sales and impact seller metrics. Undeclared allergens that lead to consumer reactions may result in lawsuits, class actions, or FDA enforcement. Sellers remain legally responsible for the safety of their products, even when fulfilled through Amazon. Sellers who repeatedly violate allergen policies risk escalated audits, Amazon account reviews, or permanent bans from selling in certain markets. Working with accredited laboratories offers sellers defensible allergen verification that supports Amazon submissions and reduces compliance risk. Labs use methods like ELISA (enzyme-linked immunosorbent assay), PCR (polymerase chain reaction), or mass spectrometry to detect even trace levels of allergens. This ensures both intentional ingredients and potential cross-contamination risks are properly identified. Labs help manufacturers assess whether shared production equipment or supplier raw materials may introduce unintended allergens into finished products. Expert labs generate clear allergen testing reports, manufacturing allergen control statements, and supporting documents that align with Amazon's compliance documentation standards. Regulatory requirements shift frequently. Expert labs stay current and guide Amazon sellers through these changing allergen compliance landscapes. Labs help sellers align allergen disclosures across multiple Amazon marketplaces, ensuring that products remain compliant whether sold in the U.S., EU, Canada, or Australia. Labs assess supplier facilities to verify allergen control protocols, manufacturing segregation, and cleaning procedures that prevent accidental cross-contact. For sellers requiring periodic verification—especially those using shared production facilities—labs offer batch-by-batch testing programs to confirm ongoing allergen compliance before shipping inventory to Amazon warehouses. Allergen labeling is a high-stakes compliance issue that directly affects consumer safety, regulatory standing, and a seller's ability to maintain active listings. Accurate allergen disclosure backed by verified laboratory testing ensures sellers meet Amazon's growing compliance demands while protecting both their customers and their Qalitex to schedule allergen testing and secure fully documented compliance for your Amazon listings across all global marketplaces.

This Airline Is Going to Start Handing Out $675 Fines to 'Unruly' Passengers: 'It Is Unacceptable'
European airline Ryanair has announced that passengers it removes from its flights for "unruly behavior" will now face an additional fine The fine for £500 — more than $675 — will be presented to anyone whose behavior "results in them being offloaded from the aircraft" 'It is unacceptable that passengers are made to suffer unnecessary disruption because of one unruly passenger's behavior," an airline spokesperson said in a statementA major European airline announced this week that passengers who are removed from flights for "unruly behavior" will now face an additional fine in an effort to crack down on what it calls "unacceptable behavior." On Thursday, June 12, Irish airline Ryanair revealed that it is introducing a £500 fine — more than $675 — to any passenger "whose unruly behavior results in them being offloaded from the aircraft." The newly implemented fines from Ryanair, which calls itself Europe's "most punctual airline," take on an "industry-wide issue affecting all airlines," the airline said in its release. The "minimum" fine comes as the airline vows to "continue to pursue disruptive passengers for civil damages." 'It is unacceptable that passengers are made [to] suffer unnecessary disruption because of one unruly passenger's behavior," a spokesperson for the airline said in a statement. "To help ensure that our passengers and crew travel in a comfortable and stress-free environment, without unnecessary disruption caused by a tiny number of unruly passengers, we have introduced a £500 fine, which will be issued to any passengers offloaded from aircraft as a result of their misconduct." "While these are isolated events which happen across all airlines, disruptive behavior in such a confined shared space is unacceptable, and we hope that our proactive approach will act as a deterrent to eliminate this unacceptable behavior onboard our aircraft," the spokesperson added. PEOPLE reached out to Ryanair for comment but did not receive an immediate response. Michael O'Leary, Ryanair's CEO, previously argued that passengers should be limited to two drinks at airports, telling the Daily Telegraph in August that authorities "don't allow people to drink-drive, yet we keep putting them up in aircraft at 33,000ft." "In the old days, people who drank too much would eventually fall over or fall asleep. But now those passengers are also on tablets and powder," he said. "It's the mix. You get much more aggressive behavior that becomes very difficult to manage." Back in January, the airline took legal action against a passenger in Ireland, seeking £12,500 — or roughly $17,000 — claiming that they disrupted a flight to the Canary Islands, per The Guardian. The 160 passengers on board had to 'face unnecessary disruption as well as [lose] a full day of their holiday," the company said at the time, according to the outlet.

Over in the U.S., unruly passenger incidents reported to the Federal Aviation Administration peaked in 2021, when 5,973 were reported. A total of 2,102 were reported in 2024, with 699 accounted for so far in 2025. From 2021 to 2023, the FAA levied a total of $20.9 million in fines against "unruly" passengers. Unruly passengers can face a felony conviction if referred to the FBI, fines of up to $37,000 per violation and be placed on an airline's internal no-fly list. "Former FAA Administrator Mike Whitaker reiterates that the FAA has zero tolerance for unruly passenger behavior. Dangerous passengers put everyone at risk," the agency shared in a statement on its website. "Threatening or violent behavior can distract and disrupt crew members from their primary responsibility — to ensure the safety of all passengers." Read the original article on People
