Scientists accuse Ireland and New Zealand of methane ‘accounting trick'
A group of 26 climate scientists from around the world have penned an open letter to New Zealand and Ireland criticising how the methane greenhouse gas is measured. In Ireland's case, it may be a reaction to the programme for government 2025 commitment to "recognise the distinct characteristics of biogenic methane, as described by the Intergovernmental Panel on Climate Change, and advocate for the accounting of this greenhouse gas to be re-classified at EU and international level". The 26 scientists, in an open letter shared with the London-based Financial Times newspaper, said governments with large livestock sectors, including those of Ireland and New Zealand, are increasingly using a new method for calculating methane's effect on climate change which estimates its contribution to warming based on how emissions are changing relative to a baseline. They specifically accused politicians in New Zealand and Ireland of using an 'accounting trick' to back their sheep and cattle industries. It is believed they are referring to GWP*, a version of the Global Warming Potential formula devised by the Intergovernmental Panel on Climate Change. Other climate researchers, at the University of Oxford, came up with GWP* about six years ago, as a better way for governments to set emissions targets for different greenhouse gases. They said the original GWP100 method did not reliably account for the different impacts of long-lived (such as carbon dioxide) and short-lived (such as methane) gases. They said different lifespans of emissions were crucial to understanding their potential to warm the earth's atmosphere. Carbon dioxide accumulates in the atmosphere, and even if its emissions ceases, the warming they caused would continues for centuries. But methane does not accumulate, being relatively rapidly removed naturally from the atmosphere. But GWP100 does not allow for this, according to the GWP* camp. Now, a different scientist at the University of Oxford, Paul Behrens, global professor of environmental change at the university, is one of the 26 whose open letter to the Financial Times warned some governments are misapplying GWP*, to justify allowing emissions to remain flat rather than decline. They warned this could set a precedent, allowing other countries to justify minimal reductions in methane emissions, and jeopardising commitments under the 2015 Paris Agreement as well as the Global Methane Pledge launched in 2021. Myles Allen, professor of geosystem science at Oxford University's physics department, and one of the scientists behind GWP*, said governments, not scientists, must decide whether farmers should undo past warming from herd growth. He still supports separate targets for methane and carbon dioxide, saying GWP100 overstates the warming impact of constant methane emissions, and is slow to reflect the impact of emission changes.

G42's Khazna Data Centers To Build AI-capable Data Center In Türkiye
Khazna Data Centers has announced plans to build an AI-capable data center in Türkiye, with a potential capacity of up to 100MW, after securing a site in Başkent, OIZ, Ankara. The announcement comes against a backdrop of sustained interest and investment in AI within the country. Stanford University's Artificial Intelligence Index for 2025 found that Türkiye had seen a 198% increase in AI talent concentration between 2016 and 2024. It also follows the signing of a number of MOUs and strategic agreements, worth more than USD 50 billion, between the UAE and Türkiye in 2023. With one of the fastest-expanding networks of hyperscale data centers globally, Khazna provides the foundation layer of future economies being built around the world by delivering sustainable, scalable digital infrastructure. Khazna empowers governments, businesses, and societies to thrive in the digital age with data centers that are designed to handle the high-density computing requirements essential for the next-generation, AI-powered applications powering the future economy. The new data center in Ankara has been designed with the flexibility to host a variety of workloads, ranging from AI to cloud and other critical applications. While the first phase will constitute a cloud-focused design, the modular facility can be expanded and adapted to meet evolving demands across diverse technological requirements, ensuring robust support for future innovations. As with Khazna's other facilities, the new data center in Ankara will be built to maximize operational efficiency. The innovative design incorporates advanced features to enhance energy efficiency and minimize environmental impact. These include the use of low Global Warming Potential (GWP) refrigerants that do not contain Hydrofluorocarbons (HFCs), the integration of solar photovoltaic (PV) panels, and the use of low-carbon and recycled materials. Additionally, the facility will explore the use of solar water heating systems, as well as employ high-efficiency adiabatic chillers that maximize the use of free cooling where possible. The design also incorporates systems for reusing wastewater and generators capable of running on Hydrotreated Vegetable Oil (HVO) fuel, further reducing the facility's carbon footprint. Hassan Alnaqbi, CEO of Khazna Data Centers, said: 'We're proud to be supporting the efforts being made in Türkiye to create an advanced economy with AI at its heart – and we hope to be able to provide the foundation layer for this. We believe this data center will add to the country's impressive economic growth, encouraging innovation and accelerating digital transformation.' H.E. Saeed Thani Hareb Al Dhaheri, Ambassador of the UAE to Türkiye, added, 'Khazna Data Centers' expansion into Türkiye is a testament to the deepening ties between our countries. Relations with Türkiye are of great importance within the UAE's strategy to strengthen its partnerships, expand its relations and reinforce bridges of cooperation in all fields.' Khazna is due to appoint a general contractor in Q2 2025 and, following this facility's completion, intends to continue investing in Türkiye and expanding its data center network. 0 0

Vertiv Unveils Eco-Friendly Liebert EFC Cooling Unit
Vertiv, a global digital infrastructure solutions provider, has upgraded its thermal management product lineup. The new Vertiv™ Liebert EFC free cooling unit now features a low-GWP (Global Warming Potential) refrigerant. This innovation is designed to meet strict environmental standards in data center applications, including colocation and cloud services. Available across Europe, the Middle East, and Africa (EMEA), the Liebert EFC offers capacities from 150 to 450 kW. The Vertiv™ Liebert EFC integrates indirect air-to-air heat exchange and evaporative cooling. With its patented polymer heat exchanger and inverter-driven compressor technology, the unit enhances efficiency by up to 19% compared to previous models. It also achieves a partial Power Usage Effectiveness (pPUE) as low as 1.05. A major advantage of the Liebert EFC is its flexibility. Users can reduce power or water usage through software controls, allowing the system to switch to free cooling mode based on site-specific conditions. This feature helps data center owners lower their environmental impact while ensuring continuous cooling. The unit also offers full water independence with direct expansion (DX) backup, ensuring reliability without needing water. Sam Bainborough , Vice President of Thermal Business EMEA at Vertiv, said, 'As sustainability becomes a priority, businesses are seeking cooling solutions that minimize resource use while ensuring operational flexibility.' He added, 'The Liebert EFC offers a flexible, game-changing system that maximizes free cooling using the natural power of evaporation.'
