With near-instantaneous tracking of global CO₂ and methane emissions, real-time emissions data from Climate TRACE enables cities, countries, and companies to make data-driven decisions.
For the first time, the world has access to monthly data on global greenhouse gas emissions, based not on promises or projections, but on verified, observed information. This major shift began on March 28, 2025, when Climate TRACE released its first monthly update using real-time satellite tracking, ground sensors, and artificial intelligence (AI). The data is only 60 days old, a huge improvement over traditional reports that often lag by one to two years.
This development could change how we respond to climate change. Instead of relying on outdated reports or self-reported data from countries and corporations, we now have an independent, transparent system to show who is polluting, where, and how much. This new wave of climate data aims to hold polluters accountable and give decision-makers timely, accurate information.
Climate TRACE—a coalition supported by former U.S. Vice President Al Gore—launched this system to offer the world what financial markets have had for decades: fast, reliable data. The group has built what some are calling a “climate Bloomberg Terminal,” allowing governments, businesses, and the public to track emissions with the same urgency used to monitor stock prices or employment numbers.
In its January 2025 report, Climate TRACE found that total emissions reached 5.26 billion metric tons of CO₂ equivalent (CO₂e). That’s a small but important 0.59% drop from January 2024. Methane, a more powerful greenhouse gas than carbon dioxide, remained steady at 32.24 million tons.
This kind of near-real-time emissions data could dramatically reshape how nations, cities, and industries plan for the future.
Historically, global emissions tracking depended on government reports and corporate disclosures, many of which were incomplete or outdated. Climate TRACE changes that.
The system monitors over 660 million emission sources across the globe. These include power plants, industrial sites, farms, vehicles, and shipping ports. It uses satellite heat signatures, spectral imaging, and operational data to estimate emissions. The AI models cross-check data from different sources and combine it with ground-based measurements for higher accuracy.
While no method is perfect, this system represents a major step forward. It functions like a financial audit, offering third-party verification that replaces guesswork with accountability.
The January 2025 data offer a clear view of how various parts of the global economy are performing in terms of emissions. Some sectors made progress, while others fell behind:
- Transportation showed the biggest improvement, cutting emissions by 1.6% year over year.
- Power generation and fossil fuel operations also saw decreases.
- Waste management and manufacturing, on the other hand, produced more emissions than the year before.
This information is crucial for setting policy and targeting interventions. For example, a city investing in electric public transportation can now track whether those investments are working within two months, not two years.
Real-time emissions data provides a clear picture of where progress is being made and where it’s stalled.
- The transportation sector showed the largest improvement, cutting emissions by 1.6% compared to the previous year.
- Emissions from power generation and fossil fuel operations also dropped.
- On the other hand, emissions from manufacturing and waste management increased.
These shifts matter. If policymakers are aware of and have evidence that certain sectors are lagging, they can target regulations and incentives more effectively.
The same applies to countries:
- China led the way with a 1.1% drop in emissions, equal to 17.4 million metric tons.
- The U.S. followed with a 0.28% reduction.
- India, Russia, and the European Union also recorded slight decreases.
Cities are being tracked, too. Dortmund, Germany, and Pohang-si, South Korea, made strong progress, while cities like Ma’anshan and Anshan in China saw emissions rise.
This isn’t just academic. Cities and businesses have already begun putting Climate TRACE’s real-time emissions data to work.
San Francisco, for example, used the platform to evaluate emissions from its ferry system. It found that switching just one route to electric power could cut CO₂e by 2,000 metric tons per year. That insight, previously buried in annual reviews, now shows up in weeks.
Meanwhile, the global shipping company Maersk has been using the data to track emissions across its fleet. The company plans to reroute cargo through cleaner ports and replace its most polluting ships by 2030.
By enabling quick action, this data transforms vague climate pledges into measurable progress.
Best of all, Climate TRACE is open to the public. You don’t need a government passcode or insider access to use it.
You can visit ClimateTRACE.org and search real-time emissions data by country, city, sector, or even individual power plants. The platform features a clean interface that enables you to compare month-to-month changes and download data for further analysis.
Teachers are already using it in classrooms. Local environmental groups are using it to pressure city councils. And journalists are using it to fact-check corporate sustainability claims.
This transparency is a game-changer. It puts climate power into everyone’s hands.
Climate TRACE’s entire dataset is open to the public. Anyone—from journalists to researchers to local activists—can explore the information and use it to demand change. The latest updates even include emissions tracking from 918 shipping ports and improved methods for separating fossil fuel methane from natural biological sources.
This kind of open access removes a common barrier to climate action: hidden data. When people don’t know where emissions come from, they can’t push for solutions. With this new tool, the public now has the power to ask hard questions and expect real answers.
Despite its promise, Climate TRACE could face serious resistance. Not everyone is happy about this level of transparency.
In the United States, the current administration has taken steps that climate scientists say could damage monitoring efforts. According to Reuters and the Honolulu Star-Advertiser, the government is moving to cancel the lease for Hawaii’s Mauna Loa Observatory, which has tracked atmospheric CO₂ for over 60 years.
More than 1,900 scientists criticized proposed cuts to the Environmental Protection Agency (EPA) budget in an open letter, warning that these changes would weaken essential protections and climate data collection.
Climate TRACE, because it doesn’t rely on self-reporting, threatens both political and industrial interests. If it continues to expose large polluters, it could face pressure from powerful groups that prefer to keep emissions hidden.
Climate TRACE proves that we can track emissions like we track the stock market—with precision and urgency. But whether it continues depends on global will.
Will governments support or silence this real-time emissions data tool? Will the public use the data to demand accountability? Or will this new source of truth be pushed aside before it changes the system?
The answers to those questions will shape climate action for decades.
This is brilliant!
