In Kenya’s Laikipia County where temperatures can reach as high as 30 degrees Celsius, a local building technology is helping homes stay cooler while supporting education, creating jobs and improving the livelihoods and resilience of community residents, Climate Home News found on a visit to the region.
Situated in a semi-arid region, houses in Laikipia are mostly built with wood or cement blocks with corrugated iron sheets for roofing. This building method usually leaves the insides of homes scorching hot – and as global warming accelerates, the heat is becoming unbearable.
Peter Muthui, principal of Mukima Secondary School in Laikipia County, lived in these harsh conditions until 2023, when the Laikipia Integrated Housing Project began in his community.
The project uses compressed earth block (CEB) technology, drawing on traditional building methods and local materials – including soil, timber, grass and cow dung – to keep buildings cool in the highland climate. The thick earth walls provide insulation against the heat.

“Especially around the months of September all the way to December, it is very, very hot [in Laikipia], but as you might have noticed, my house is very cool even during the heat,” Muthui told Climate Home News.
His school has also deployed the technology for classrooms and boarding hostels to ensure students can carry on studying during the hottest seasons of the year. This way, they are protected from severe conditions and school closures can be avoided. In South Sudan, dozens of students collapsed from heat stroke in the capital Juba earlier this year, causing the country to shutter schools for weeks.
COP30 sees first action call on sustainable, affordable housing
The buildings and construction sector accounts for 37% of global emissions, making it the world’s largest emitter of greenhouse gases, according to the UN Environment Programme (UNEP). While calls to decarbonise the sector have grown, meaningful action to cut emissions has remained limited.
At COP28 in Dubai, the United Arab Emirates and Canada launched the Cement and Concrete Breakthrough Initiative to speed up investment in the technologies, policies and tools needed to put the cement and concrete industry on a net zero-emissions path by 2050.
Canada’s innovation minister, François-Philippe Champagne, said the initiative aimed to build a competitive “green cement and concrete industry” which creates jobs while building a cleaner future.
Coordinated by UNEP’s Global Alliance for Buildings and Construction, the council has urged countries to embed climate considerations into affordable housing from the outset, “ensuring the drive to deliver adequate homes for social inclusion goes hand in hand with minimising whole-life emissions and environmental impacts”.

With buildings responsible for 34% of energy-related emissions and 32% of global energy demand, and 2.8 billion people living in inadequate housing, the ICBC stressed that “affordable, adequate, resource-efficient, low-carbon, climate-resilient and durable housing is essential to a just transition, the achievement of the Sustainable Development Goals and the effective implementation of the Paris Agreement”.
Compressed earth offers local, green alternative
By using locally sourced materials, and just a little bit of cement, the compressed earth technology is helping residents in Kenya’s Laikipia region to build affordable, climate-smart homes that reduce emissions and environmental impacts while creating economic opportunities for local residents, said Dacan Aballa, construction manager at Habitat for Humanity International, the project’s developers.
Aballa said carbon emissions in the construction sector occur all through the lifecycle, from material extraction, processing and transportation to usage and end of life. However, by switching to compressed earth blocks, residents can source materials available in their environment, avoiding nearly all of that embedded carbon pollution.
According to the World Economic Forum (WEF), global cement manufacturing is responsible for about 8% of total CO2 emissions, and the current trajectory would see emissions from the sector soar to 3.8 billion tonnes per year by 2050 – a level that, compared to countries, would place the cement industry as one of the world’s top three or four emitters alongside the US and China.
Comparing compressed earth blocks and conventional materials in terms of carbon emissions, Aballa said that by using soil native to the area, the process avoids the fossil fuels that would normally have been used for to produce and transport building materials, slashing carbon and nitrogen dioxide emissions.
The local building technology also helps save on energy that would have been used for cooling these houses as well as keeping them warm during colder periods, Aballa explained.
Justin Atemi, water and sanitation officer at Habitat for Humanity, said the brick-making technique helps reduce deforestation too. This is because the blocks are left to air dry under the sun for 21 days – as opposed to conventional fired-clay blocks that use wood as fuel for kilns – and are then ready for use.

Traditional knowledge becomes adaptation mechanism
Africa’s red clay soil was long used as a building material for homes, before cement blocks and concrete became common. However, the method never fully disappeared. Now, as climate change brings higher temperatures, this traditional building approach is gaining renewed attention, especially in low-income communities in arid and semi-arid regions struggling to cope with extreme heat.
From Kenya’s highlands to Senegal’s Sahelian cities, compressed earth construction is being repurposed as a low-cost, eco-friendly option for homes, schools, hospitals – and even multi-storey buildings.
Senegal’s Goethe-Institut in Dakar was constructed primarily using compressed earth blocks. In Mali, the Bamako medical school, which was built with unfired mud bricks, stays cool even during the hottest weather.
And more recently, in Nigeria’s cultural city of Benin, the just-finished Museum of West African Art (MOWA) was built using “rammed earth” architecture – a similar technology that compresses moist soil into wooden frames to form solid walls – making it one of the largest such structures in Africa.
SYDNEY, Saturday 28 February 2026 — Greenpeace International and Greenpeace organisations in the US announce they will seek a new trial and, if necessary, appeal the decision with the North Dakota Supreme Court following a North Dakota District Court judgment today awarding Energy Transfer (ET) USD $345 million.
ET’s SLAPP suit remains a blatant attempt to silence free speech, erase Indigenous leadership of the Standing Rock movement, and punish solidarity with peaceful resistance to the Dakota Access Pipeline. Greenpeace International will also continue to seek damages for ET’s bullying lawsuits under EU anti-SLAPP legislation in the Netherlands.
Mads Christensen, Greenpeace International Executive Director said: “Energy Transfer’s attempts to silence us are failing. Greenpeace International will continue to resist intimidation tactics. We will not be silenced. We will only get louder, joining our voices to those of our allies all around the world against the corporate polluters and billionaire oligarchs who prioritise profits over people and the planet.
“With hard-won freedoms under threat and the climate crisis accelerating, the stakes of this legal fight couldn’t be higher. Through appeals in the US and Greenpeace International’s groundbreaking anti-SLAPP case in the Netherlands, we are exploring every option to hold Energy Transfer accountable for multiple abusive lawsuits and show all power-hungry bullies that their attacks will only result in a stronger people-powered movement.”
The Court’s final judgment today rejects some of the jury verdict delivered in March 2025, but still awards hundreds of millions of dollars to ET without a sound basis in law. The Greenpeace defendants will continue to press their arguments that the US Constitution does not allow liability here, that ET did not present evidence to support its claims, that the Court admitted inflammatory and irrelevant evidence at trial and excluded other evidence supporting the defense, and that the jury pool in Mandan could not be impartial.[1][2]
ET’s back-to-back lawsuits against Greenpeace International and the US organisations Greenpeace USA (Greenpeace Inc.) and Greenpeace Fund are clear-cut examples of SLAPPs — lawsuits attempting to bury nonprofits and activists in legal fees, push them towards bankruptcy and ultimately silence dissent.[3] Greenpeace International, which is based in the Netherlands, is pursuing justice in Europe, with a suit against ET under Dutch law and the European Union’s new anti-SLAPP directive, a landmark test of the new legislation which could help set a powerful precedent against corporate bullying.[4]
Kate Smolski, Program Director at Greenpeace Australia Pacific, said: “This is part of a worrying trend globally: fossil fuel corporations are increasingly using litigation to attack and silence ordinary people and groups using the law to challenge their polluting operations — and we’re not immune to these tactics here in Australia.
“Rulings like this have a chilling effect on democracy and public interest litigation — we must unite against these silencing tactics as bad for Australians and bad for our democracy. Our movement is stronger than any corporate bully, and grows even stronger when under attack.”
Energy Transfer’s SLAPPs are part of a wave of abusive lawsuits filed by Big Oil companies like Shell, Total, and ENI against Greenpeace entities in recent years.[3] A couple of these cases have been successfully stopped in their tracks. This includes Greenpeace France successfully defeating TotalEnergies’ SLAPP on 28 March 2024, and Greenpeace UK and Greenpeace International forcing Shell to back down from its SLAPP on 10 December 2024.
[1] The judgment entered by North Dakota District Court Judge Gion follows a jury verdict finding Greenpeace entities liable for more than US$660 million on March 19, 2025. Judge Gion subsequently threw out several items from the jury’s verdict, reducing the total damages to approximately US$345 million.

[3] Energy Transfer’s first lawsuit was filed in federal court in 2017 under the RICO Act – the Racketeer Influenced and Corrupt Organizations Act, a US federal statute designed to prosecute mob activity. The case was dismissed in 2019, with the judge stating the evidence fell “far short” of what was needed to establish a RICO enterprise. The federal court did not decide on Energy Transfer’s claims based on state law, so Energy Transfer promptly filed a new case in a North Dakota state court with these and other state law claims.
[4] Greenpeace International sent a Notice of Liability to Energy Transfer on 23 July 2024, informing the pipeline giant of Greenpeace International’s intention to bring an anti-SLAPP lawsuit against the company in a Dutch Court. After Energy Transfer declined to accept liability on multiple occasions (September 2024, December 2024), Greenpeace International initiated the first test of the European Union’s anti-SLAPP Directive on 11 February 2025 by filing a lawsuit in Dutch court against Energy Transfer. The case was officially registered in the docket of the Court of Amsterdam on 2 July, 2025. Greenpeace International seeks to recover all damages and costs it has suffered as a result of Energy Transfers’s back-to-back, abusive lawsuits demanding hundreds of millions of dollars from Greenpeace International and the Greenpeace organisations in the US. The next hearing in the Court of Amsterdam is scheduled for 16 April, 2026.
The Trump administration’s relentless rollback of public health and environmental protections has allowed widespread toxic exposures to flourish, warn experts who helped implement safeguards now under assault.
By Liza Gross
In a new report that outlines a dozen high-risk pollutants given new life thanks to weakened, delayed or rescinded regulations, the Environmental Protection Network, a nonprofit, nonpartisan group of hundreds of former Environmental Protection Agency staff, warns that the EPA under President Donald Trump has abandoned the agency’s core mission of protecting people and the environment from preventable toxic exposures.
The country’s largest exporter of liquefied natural gas benefited from what critics say is a questionable IRS interpretation of tax credits.
By Phil McKenna
Cheniere Energy, the largest producer and exporter of U.S. liquefied natural gas, received $370 million from the IRS in the first quarter of 2026, a payout that shipping experts, tax specialists and a U.S. senator say the company never should have received.
