Achieving decarbonization in digital infrastructure
materials equipment power

iMasons Climate Accord is a coalition of companies united on carbon reductions in digital infrastructure.

Our mandate is to achieve global carbon accounting of digital infrastructure to influence market-based decisions and drive the industry to achieve decarbonization.

The alignment is there. The biggest companies in the world are saying, 'We're in.'

Companies participating in the Climate Accord agree to an open standard and governance to report carbon impact in materials, products, and power across digital infrastructure. Memberships enable showcasing sustainability initiatives and efforts while contributing valuable data and perspective to the conversation.

We've never had more unity on a common cause. We don't have the luxury of time.

iMasons Climate Accord Summit: Building a Decarbonized Future Together

December 8 – 10, 2025 | Los Angeles, CA

Over three days, leaders from the world’s top tech companies gathered for a high-impact summit focused on advancing sustainability, reducing emissions, and improving efficiency in digital infrastructure. As a cornerstone of the digital economy, this sector plays a critical role in shaping a low-carbon future.

Climate Accord progress is made by members in Working Groups (WGs) worldwide, each with a time-bound mission defined by the Governing Body (GB).

Power

Enable transparency of carbon content of power on a real-time basis and build market-based incentives to source zero carbon power 24/365 to decarbonize data center power worldwide.

Materials

Promote accurate communication of embodied carbon and creating market-based incentives to prioritize low-carbon building materials.

Equipment

Facilitate clear disclosure of embodied carbon and creating market-based incentives to choose low-carbon equipment.

Best Practices for Data Center LCAs

January 23, 2026 | Case Studies, Materials WG

This case study is intended to assist data center developers, owners, and design professionals by providing guidance and best practices for measuring—and ultimately reducing—the embodied carbon impacts (expressed as CO₂e in this publication) of data center construction through the use of Life Cycle Assessment (LCA).

Open Compute Project Foundation and iMasons Develop Taxonomy for Carbon Disclosure

October 7, 2025 | Press Releases

The Open Compute Project Foundation (OCP), in collaboration with the iMasons Climate Accord (iCA), today unveiled the Embodied Carbon Disclosure – OCP Base Specification, with contributions from Google, Meta, Microsoft, Schneider Electric and more, the first major work product from their alliance.

Heating Emergency Power System Engines with Heat Pumps

October 2, 2025 | Case Studies

Standby generators are an untapped source for energy efficiency. Retrofitting a high efficiency heat pump to the existing engine heating infrastructure of a genset can reduce the energy draw needed to maintain startability of the system by up to 65%.
