Gap between Q1 heat pump and conventional AC sales shrinks to a record low in the US
The gap between US traditional air conditioner and heat pump sales narrowed from 16% in Q1 2025 to 2% in Q1 2026, signaling continued demand for heat pumps despite the repeal of federal tax incentives and waning consumer interest in new AC units. Heat pumps, which are two to four times more efficient than fossil-fueled alternatives, offer a scalable zero- emissions solution for residential heating and cooling needs.

Deutsche Bank collaborated with Lufthansa Group to fund the deployment of over 1,700 tons of SAF, reducing carbon emissions by an estimated 6,000 tons. The investment is part of Deutsche Bank’s broader plan to reduce Scope 3 emissions by 50% compared with a 2019 baseline by 2030. [ESG Dive]
Sustainable Materials & Products
Dutch carbon removal startup Paebbl launched the world’s first Environmental Product Declaration-certified carbon-negative construction material. The proprietary mineralization process captures and converts atmospheric carbon into stable minerals for use in concrete, sequestering 149 kilograms of carbon dioxide per ton of concrete and allowing large-scale infrastructure projects to function as permanent carbon storage sites. [Carbon Herald]
Japanese drink company Suntory Beverage & Food announced a $73 million climate plan to both cut Scope 3 emissions and protect its 10,500-ton annual blackcurrant fruit supply from rising temperatures by 2027. The investment will fund the development of heat-tolerant crop varieties, ensuring long-term ingredient security and agricultural stability for Suntory’s beverage portfolio. [Net Zero Compare]
The Spanish government allocated ~$364 million to cement producers Votorantim Cimentos España and Cemex España to scale carbon capture and hydrogen technologies across the nation's industrial sector. The funding will support Votorantim’s efforts to reach an emissions intensity of 475 kilograms of carbon dioxide per ton by 2030 through carbon liquefaction infrastructure as well as enable Cemex to replace fossil fuels with waste-to-hydrogen systems at its Catalonia facility.

Notable Corporate Commitments
Amazon signed a long-term agreement to purchase 1.95 million metric tons of carbon removal credits from South Africa’s Spekboom Restoration Project. South African developer Imperative will restore 50,000 hectares of native Spekboom shrubs, sequestering a projected 35 million metric tons of carbon dioxide over 40 years. [Yahoo! Finance]
Siemens and German climate tech firm Ucaneo partnered to scale a first-of- its-kind Direct Air Capture (DAC) facility into one of the largest operational electrochemical DAC plants in the world. The facility, which will be Germany’s first DAC project to store captured emissions within geological formations, can remove up to 165 tons of carbon dioxide annually using an electrochemical process to purify atmospheric carbon. [Renewable Carbon]
Global Climate Commitments and Progress
China announced a national energy plan to generate 50% of its electricity from non-fossil sources and reduce power-sector carbon dioxide emissions intensity by 10% by 2030. This strategy accelerates the country’s existing deployment of 300 gigawatts of non-pumped hydro energy storage and targets 2 million metric tons of annual renewable hydrogen production. [ESG News]
Oman signed agreements with a consortium led by EDF to develop a new 2 gigawatt pumped hydro plant, which is set to become the largest hydro storage facility in the Middle East. The planned Jabal Abyad hydro plant will provide the long-duration energy storage necessary to stabilize the national power system and help the country scale dispatchable renewable power. [Renewables Now]
Singapore initiated a $100 billion climate resilience strategy by commencing the "Long Island" project to reclaim 800 hectares of land and defend the city- state against rising sea levels. This massive adaptation effort integrates a new reservoir and advanced tidal gates to provide flood protection for the nation’s East Coast region, which is currently situated less than five meters above sea level.
