The solution is clear — build solar PV in locations where it will displace coal-fired and other highly polluting power plants.

Most of those emissions reductions can be found in Southeast Asia, Africa, Latin America, and Eastern Europe. 🌏 ☀️

The new Climate TRACE tool leverages WattTime data, combined marginal emissions rates, and asset-level emissions profiles to identify the greatest opportunities for achievable decarbonization.

Choosing the most effective power sector projects makes a big difference to how quickly we reduce global emissions. With this tool, Climate TRACE now shows not only which assets have the biggest opportunities, it also shows what can be done to capture those opportunities.
November 13, 2025 at 6:05 PM
The biggest opportunity?

Decarbonizing the power sector, which is the number one source of carbon emissions globally.

At scale, Climate TRACE data show this could reduce global emissions by 9 gigatonnes.

Since the founding of Climate TRACE, WattTime has been working with our fellow coalition members to present clear and actionable pathways to decarbonization.

The emissions reduction roadmap tool shows at least one proven and feasible emissions reduction strategy for every emitting source on the emissions map — that’s over 700 million emitting facilities.

Put simply: for the fastest and most cost-effective climate outcomes, don’t match CFE with your load, match it with dirty power plants.

Earth’s climate doesn’t care if renewables are “hourly-matched” and “deliverable” to the data center’s load. What matters for the climate is that carbon-free energy (CFE) displaces fossil fuel power plants.

Where the next #solar farm or data center gets built matters to the climate.

Building renewables on the dirtiest grids, and data centers on the cleanest ones, will drive the fastest progress on #emissions.

We could not reach this milestone without the collaboration of our partners like Toyota, Apple, and BMW who are supercharging emissions reductions. Join the movement with #AER technology for smart devices. watttime.org/news-and-ins...
More than one billion smart devices now using marginal emissions data to slash power grid pollution with WattTime's 'AER' - WattTime
As Automated Emissions Reduction (AER) technology continues to scale in smart devices across the globe — including Toyota and BMW EVs, Amazon and Google Nest smart thermostats, Apple iPhones, and more...

🚙EV Charging in particular is making waves with this technology, demonstrating the potential to reduce grid emissions from charging by up to 90% on individual days.

“Based on the US Department of Energy’s projections of growth rates, if everyone adopted this... technology, AER could prevent three billion tonnes of carbon dioxide annually by 2030. That’s about 8% of all greenhouse gas emissions…” said WattTime’s executive director, Gavin McCormick.

Thanks to our incredible partners, some of the largest tech companies have deployed this emissions-slashing technology, resulting in less pollution from the electricity consumption of internet-connected devices like smart phones, thermostats, EV chargers, and more.

“...when a company buys RECs from a solar project in California, where the grid is saturated with solar, it will do less to reduce emissions than if it bought RECs from a solar project in Wyoming, where the grid is still largely powered by coal...” Pontecorvo explains.
