Brimstone y su proceso integral para producir cemento más limpio y minerales críticos
La empresa afirma que puede producir todo tipo de productos a partir de un solo tipo de roca, dando paso a una nueva «revolución industrial». Brimstone está logrando avances en dos problemas industriales: reducir las emisiones del cemento y ofrecer una vía para producir más minerales críticos dentro de Estados Unidos.
Brimstone and its one-stop process for making cleaner cement and critical minerals
Brimstone is making strides on two industrial problems, reducing the emissions from cement and providing a way to produce more critical minerals within the US. If the company can do both, with the same rocks in the same plant, it would unlock a cleaner and more efficient process for manufacturing building materials, aluminum, steel, and more. Brimstone is a code-switching climate tech company for these polarized political times.
Próximamente: nuestra lista de 2026 de empresas de tecnología climática que hay que seguir
A principios de este mes, la ONU anunció que el planeta superará los 1,5 °C de calentamiento, "probablemente en los próximos años", lo que disipa cualquier esperanza que aún quedara de que las naciones reduzcan sus emisiones con la suficiente rapidez como para cumplir el objetivo más ambicioso del Acuerdo de París. En Estados Unidos, el segundo país más emisor del mundo, su líder sigue negando la realidad climática y desmantelando las políticas climáticas.
Coming soon: Our 2026 list of Climate Tech Companies to Watch
Earlier this month, the UN announced the planet will tip past 1.5 ˚C of warming, “likely within the next few years,” squashing any lingering hope that nations would cut emissions fast enough to achieve the loftiest goal of the Paris climate agreement. In the US, the world’s second-largest-emitting country, its leader continues to deny climate realities and unravel climate policies. Big Tech is backpedaling on its climate ambitions, as companies race to build massive AI data centers.
Este roteiro poderia nos ajudar a decidir se devemos implementar a geoengenharia solar
Os experimentos, os estudos e a infraestrutura que seriam necessários para tomar decisões fundamentadas sobre o uso da geoengenharia solar foram divulgados em um roteiro de uma organização sem fins lucrativos de São Francisco, nos Estados Unidos, revela a MIT Technology Review. Há meio século, cientistas vêm explorando a possibilidade de conter as mudanças climáticas por meio da liberação de partículas refletoras na estratosfera, imitando os efeitos de resfriamento das erupções vulcânicas.
This road map could help us decide whether to deploy solar geoengineering
A San Francisco nonprofit has published a detailed road map of the experiments, studies, and infrastructure that it says would be needed to make informed decisions about the use of solar geoengineering, MIT Technology Review can reveal. Scientists have now spent half a century exploring the possibility that we could counteract climate change by releasing reflective particles into the stratosphere, mimicking the cooling effects of volcanic eruptions.
This road map could help us decide whether to deploy solar geoengineering
2 days ago One company has a simple-sounding plan to help save the planet: take a food additive and the mineral that makes eggshells hard, produce tiny particles out of them, spray them into the atmosphere and cool the world. Stardust Solutions, an Israeli-US company founded in 2023 and led by two former …
Letter: Sheridan Media, The Sheridan Press, refuse to publish important Election Information. Not all media outlets have your best interest at heart.
On July 8, 2026, Dylan Dalton, a candidate in the Sheridan County Clerk race, withdrew from the election. On July 21, 2026, Mr. Dalton penned a letter endorsing candidate Christine Temple in the race for Sheridan County Clerk. He emailed a copy of this letter to The Sheridan Press and to Sheridan Media for publication. Neither outlet responded to his submission.
Por que as contas sobre emissões de gases do esterco não fecham
Há algo de podre nas políticas climáticas da Califórnia, nos Estados Unidos. Anos atrás, o estado criou um sistema que paga pecuaristas de todo o país para transformar o metano emitido pelo esterco bovino em gás natural, incentivando o setor de laticínios a produzir um gás que queimamos em vez de um que apenas polui o ar. Ele se tornou extremamente popular porque os subsídios são muito lucrativos.
Why worms (and microbes) are catching on as a manure pollution solution
2 hours ago Copenhagen is still the most livable city in the world. That's based on the Economist Intelligence Unit's new ranking of 173 cities, using five measures to rank the quality of life: stability, healthcare, culture and environment, education, and infrastructure. "Copenhagen's continued dominance comes …
Why worms (and microbes) are catching on as a manure pollution solution
Anthony Agueda, a third-generation California dairy farmer, pulls a rake through a bed of dark, wet wood chips on his family’s land in Hickman, a tiny town in the state’s agricultural heartland. He reaches down with both hands and pulls up a clump of muck, turning it over to reveal a half-dozen squirming red earthworms.
Why California’s carbon manure math doesn’t add up
Something stinks in California’s climate policies. Years ago, the state set up a system that pays cattle farmers across the country to turn the methane emitted from cattle manure into natural gas, encouraging the dairy sector to produce a gas we burn instead of one that just pollutes the air. It’s become wildly popular because the subsidies are extremely lucrative. But a growing body of research suggests the program is a case study in the shortcomings of our preferred approaches to climate action.
Hacking the atmosphere: Geoengineering gets a reality check
Jim Franke pulls away the cover page of a presentation on the wraparound desk in his office, revealing an illustration of an odd-looking aircraft with massive wings stretching out from a stubby fuselage. The uncrewed plane is soaring thousands of meters higher than commercial jets fly—so high you can see the curvature of the Earth. It’s precisely the type of aircraft one would need to begin artificially cooling the planet.
MIT Technology Review en español
A principios de la década de 2020, una pequeña empresa de acuicultura en Portland, Maine (Estados Unidos), consiguió más de 50 millones de dólares (aprox. 46 millones de euros) al presentar un plan para aprovechar la naturaleza en la lucha contra el cambio climático. La empresa, Running Tide, afirmaba que podía hundir suficiente kelp en el fondo marino como para secuestrar mil millones de toneladas de dióxido de carbono para este año, según uno de sus primeros clientes.
MIT Technology Review en español
El 1 de junio de 2023, mientras una sofocante ola de calor azotaba Quebec (Canadá), miles de rayos cruzaron la provincia, provocando más de 120 incendios forestales. Los incendios arrasaron bosques resecos y praderas marchitas, ardieron durante semanas y agravaron lo que rápidamente se convirtió en el peor año de incendios registrado en Canadá.
Startup afirma que pode parar raios e evitar incêndios florestais catastróficos
No dia 1º de junho de 2023, enquanto uma onda de calor sufocante castigava Quebec, no Canadá, milhares de descargas elétricas de raios cruzaram a província, desencadeando mais de 120 incêndios florestais. As chamas atravessaram vegetações ressecadas e campos de gramíneas murchas, queimaram por semanas e agravaram o que rapidamente estava se tornando o pior ano de incêndios já registrado no país.
This startup claims it can stop lightning and prevent catastrophic wildfires
On June 1, 2023, as a sweltering heat wave baked Quebec, thousands of lightning strikes flashed across the province, setting off more than 120 wildfires. The blazes ripped through parched forests and withered grasslands, burned for weeks, and compounded what was rapidly turning into Canada’s worst fire year on record.
Justiça climática global: como montar um caso contra os maiores emissores
Os Estados Unidos e a União Europeia se tornaram superpotências econômicas ao cometer atrocidades climáticas. Eles queimaram uma parcela desproporcionalmente grande do petróleo e do gás do mundo, plantando bombas-relógio de carbono que vão detonar primeiro nas partes mais pobres e mais quentes do globo.
The building legal case for global climate justice
The United States and the European Union grew into economic superpowers by committing climate atrocities. They have burned a wildly disproportionate share of the world’s oil and gas, planting carbon time bombs that will detonate first in the poorest, hottest parts of the globe.
Como uma startup espera esfriar o planeta
A Stardust Solutions acredita que pode resolver a mudança climática, mas por um preço. A startup de geoengenharia com sede em Israel disse que espera que nações lhe paguem, em breve, mais de um bilhão de dólares por ano para lançar aeronaves especialmente equipadas na estratosfera. Depois de atingirem a altitude necessária, esses aviões dispersariam partículas projetadas para refletir luz solar suficiente para longe e resfriar o planeta, supostamente sem causar efeitos colaterais ambientais.
Four bright spots in climate news in 2025
Climate news hasn’t been great in 2025. Global greenhouse-gas emissions hit record highs (again). This year is set to be either the second or third warmest on record. Climate-fueled disasters like wildfires in California and flooding in Indonesia and Pakistan devastated communities and caused billions in damage.
Cómo una controvertida ‘startup’ quiere enfriar el planeta
Stardust Solutions asegura que puede frenar el cambio climático… por un precio. La startup israelí de geoingeniería afirma que, en poco tiempo, los Estados pagarán más de mil millones de dólares al año para que lance aviones equipados con tecnología especial hacia la estratosfera. Una vez en la altitud necesaria, esas aeronaves dispersarían partículas diseñadas para reflejar la luz solar y enfriar el planeta, supuestamente sin provocar efectos ambientales adversos.
How one controversial startup hopes to cool the planet
Stardust Solutions believes that it can solve climate change—for a price. The Israel-based geoengineering startup has said it expects nations will soon pay it more than a billion dollars a year to launch specially equipped aircraft into the stratosphere. Once they’ve reached the necessary altitude, those planes will disperse particles engineered to reflect away enough sunlight to cool down the planet, purportedly without causing environmental side effects.
Desafios da remoção de carbono e o futuro do setor: uma análise aprofundada
No início da década de 2020, uma pouco conhecida empresa de aquicultura em Portland, no Maine, arrecadou mais de 50 milhões de dólares ao apresentar um plano para aproveitar a natureza no combate às alterações climáticas. A Running Tide afirmou que conseguiria afundar algas suficientes no fundo do mar para sequestrar mil milhões de toneladas de dióxido de carbono até este ano, segundo um dos seus primeiros clientes.

Big Tech’s big bet on a controversial carbon removal tactic
Over the last century, much of the US pulp and paper industry crowded into the southeastern corner of the nation, setting up mills amid sprawling timber forests to strip the fibers from juvenile loblolly, long leaf, and slash pine trees. Today, after the factories chip the softwood and digest it into pulp, the leftover lignin, spent chemicals, and remaining organic matter form a dark, syrupy by-product known as black liquor.

La administración Trump prevé recortar los fondos a dos megaproyectos de captura de CO2
El Departamento de Energía de EE. UU. parece dispuesto a poner fin a la financiación de dos grandes fábricas de absorción de carbono que, en un principio, iban a recibir más de 1000 millones de dólares en subvenciones gubernamentales, según una lista de proyectos publicada por el departamento, obtenida por MIT Technology Review y que circula entre las agencias federales.
The Trump administration may cut funding for two major direct-air-capture plants
The US Department of Energy appears poised to terminate funding for a pair of large carbon-sucking factories that were originally set to receive more than $1 billion in government grants, according to a department-issued list of projects obtained by MIT Technology Review and circulating among federal agencies. One of the projects is the South Texas Direct Air Capture Hub, a facility that Occidental Petroleum’s 1PointFive subsidiary planned to develop in Kleberg County, Texas.

How we picked promising climate tech companies in an especially unsettling year
MIT Technology Review’s reporters and editors faced a dilemma as we began to mull nominees for this year’s list of Climate Tech Companies to Watch. How do you pick companies poised to succeed in a moment of such deep uncertainty, at a time when the new Trump administration is downplaying the dangers of climate change, unraveling supportive policies for clean technologies, and enacting tariffs that will boost costs and disrupt supply chains for numerous industries?
Como Trump está a ajudar a China a ampliar a sua vantagem em energia limpa
Num dia de primavera de 1954, investigadores dos Bell Labs apresentaram os primeiros painéis solares práticos numa conferência de imprensa em Murray Hill, New Jersey, nos Estados Unidos, utilizando luz solar para fazer rodar uma roda-gigante de brinquedo perante uma multidão atónita. O futuro da energia solar parecia promissor. Na corrida para comercializar a tecnologia que inventaram, porém, os Estados Unidos acabariam por perder de forma retumbante.
EUA ganham vantagem em energia limpa
Em um dia de primavera de 1954, pesquisadores do Bell Labs apresentaram os primeiros painéis solares práticos em uma coletiva de imprensa em Murray Hill, New Jersey, nos Estados Unidos, usando luz solar para fazer girar uma roda-gigante de brinquedo diante de uma multidão atônita.

How Trump is helping China extend its massive lead in clean energy
On a spring day in 1954, Bell Labs researchers showed off the first practical solar panels at a press conference in Murray Hill, New Jersey, using sunlight to spin a toy Ferris wheel before a stunned crowd. The solar future looked bright. But in the race to commercialize the technology it invented, the US would lose resoundingly. Last year, China exported $40 billion worth of solar panels and modules, while America shipped just $69 million, according to the New York Times.
How Trump is helping China extend its massive lead in clean energy
MIT scientists may have just cracked the code on EV battery recycling Researchers just discovered a new way to build an EV battery that makes it easy to break apart at the end of its lifespan. This year, global EV sales are expected to jump almost 25% compared with 2024. As the demand for electric vehicles soars, there’s a looming concern for industry experts: …
How Trump is helping China extend its massive lead in clean energy
And now the US seems determined to repeat the mistake. In its quest to prop up aging fossil-fuel industries, the Trump administration has slashed federal support for the emerging cleantech sector, handing his nation’s chief economic rival the most generous of gifts: an unobstructed path to locking in its control of emerging energy technologies, and a leg up in inventing the industries of the future. China’s dominance of solar was no accident.
O risco do permafrost, incêndios florestais e emissões
Na primavera de 2021, os cientistas climáticos estavam perplexos. A economia global começava a recuperar dos bloqueios impostos pela Covid-19, mas, por algum motivo, os níveis de metano — um gás de efeito de estufa emitido principalmente pela agricultura e pela produção de combustíveis fósseis — dispararam na atmosfera no ano anterior, aumentando à taxa mais rápida já registada.
Los gases de efecto invernadero que no estamos teniendo en cuenta
En la primavera de 2021, los científicos climáticos se quedaron perplejos. La economía mundial acababa de salir de los confinamientos por la COVID-19, pero, por alguna razón, los niveles de metano —un gas de efecto invernadero emitido principalmente por la agricultura y la producción de combustibles fósiles— se habían disparado en la atmósfera durante el año anterior, aumentando al ritmo más rápido jamás registrado.

Google, Tract, Switch, EdgeCore, Novva, Vantage, and PowerHouse are all operating, building, or expanding huge facilities within the Tahoe Reno Industrial Center, a business park bigger than the city of Detroit.
Gases de efeito estufa esquecidos
Na primavera de 2021, os cientistas climáticos estavam perplexos. A economia global estava começando a se recuperar dos bloqueios causados pela Covid-19, mas, por algum motivo, os níveis de metano, um gás de efeito estufa emitido principalmente pela agricultura e pela produção de combustíveis fósseis, dispararam na atmosfera no ano anterior, aumentando na taxa mais rápida já registrada.
ONGs e academia salvam programas climáticos
As organizações sem fins lucrativos estão se esforçando para preservar um esforço dos EUA para modernizar a medição de gases de efeito estufa, em meio ao crescente receio de que o desmonte de programas federais pela administração Trump ofusque as contribuições do país para as mudanças climáticas.
The greenhouse gases we’re not accounting for
In the spring of 2021, climate scientists were stumped. The global economy was just emerging from the covid-19 lockdowns, but for some reason the levels of methane—a greenhouse gas emitted mainly through agriculture and fossil-fuel production—had soared in the atmosphere the previous year, rising at the fastest rate on record. Researchers around the world set to work unraveling the mystery, reviewing readings from satellites, aircraft, and greenhouse-gas monitoring stations.
