The global power grid emissions data required to take an impact-based approach to carbon accounting and decision making are now freely available for smaller organizations, ensuring that all institutions that can benefit from the data can access it.
Boston, Mass. and Oakland, Calif. – 6 March 2025 – REsurety, Inc., the leading provider of software, services, and marketplace solutions empowering the future of energy, and WattTime, an environmental tech nonprofit working to multiply positive climate impact, have today announced the launch of the Grid Emissions Data platform — a free and open resource which provides high-quality marginal emissions data covering the entire globe to qualified end users worldwide to enable an impact-based approach to carbon accounting and decision making.
Marginal emissions data, which measure the carbon impact of consuming or generating electricity at a given time and location, are a critical tool for maximizing and accurately measuring real-world carbon impacts. For example, marginal emissions data enable a strategic approach to clean energy procurement like the one McKinsey & Company recently found to be most effective at reducing emissions. But high-quality data of this nature can sometimes be difficult to access for companies without the budget to pay for it.
The Grid Emissions Data platform was made to serve small corporate buyers of clean energy and industry researchers with freely accessible, high-quality, accurate, and granular marginal emission data via a single, third-party website and database.
“More and more organizations are committed to accurately reporting the real-world impacts of their clean energy procurements,” said Lee Taylor, CEO of REsurety. “The Grid Emissions Data platform will support and accelerate that trend by offering the highest quality data available, free from the constraints of a paywall.”
The marginal emissions data provided on the new platform are consistent with the operating margin data guidelines established in the Guidelines for Quantifying GHG Reductions from Grid-Connected Electricity Projects — part of the The GHG Protocol for Project Accounting published by World Resources Institute (WRI) and The World Business Council for Sustainable Development (WBCSD). In addition, the platform directly supports the kind of approach espoused by the Emissions First Partnership; the group of corporate and tech leaders has called for a shift in corporate carbon accounting standards away from megawatt-hour matching and toward an emissions impact-centric system that maximizes greenhouse gas reductions.
“Slashing emissions is more urgent than ever. And using data like these to optimize electricity procurement, load shifting, and siting decisions at scale is the only climate solution we’ve seen with the potential to rapidly reduce over 8 billion tons of carbon dioxide equivalent per year,” said Gavin McCormick, founder and executive director of WattTime. “That’s why we knew — as two mission-driven organizations — that giving away these free data was just the right thing to do.”
Designed, developed, and maintained jointly by WattTime and REsurety, the Grid Emissions Data platform offers hourly marginal emissions data on a global scale from the prior three complete years in CSV download format. Users can retrieve data by node, region, or sub-region, where available, and data will be updated at least annually.
Qualified end users — including most smaller buyers of clean energy, auditors, academics, and regulators — can download their selected data at GridEmissionsData.io after completing a simple, free data-use agreement.
