The Environmental Protection Agency announced earlier this month that it would cease to ensure that polluting companies report their greenhouse gas emissions from it, eliminating a crucial tool that the United States uses to follow emissions and form climate policy. Climate NGOs say that their work could help fill a part of the data difference, but they and other experts fear that EPA work cannot be fully adapted.
“I do not think this system can be fully replaced,” said Joseph Goffman, the former assistant administrator of the EPA air and radiation office. “I think it could be approximated, but it will take time.”
The Clean Air Act obliges states to collect data on local pollution levels, which then declares to turn to the federal government. Over the past 15 years, EPA has also collected data on carbon dioxide, methaneand others greenhouse Sources of the country that issues a certain issue of emissions. This program is known as Greenhouse Gas Reporting Program (GHGRP) and “is really the backbone of the air quality reporting system in the United States”, explains Kevin Gurney, professor of atmospheric sciences at Northern Arizona University.
Like a myriad of other data collection processes that have been blocked or interrupted since the beginning of this year, the Trump administration has put this program in the reticle. In March, the EPA announced that it would completely reconsider the GHGRP program. In September, the agency trotted a rule proposed to eliminate the obligations to declare sources ranging from power plants to oil and gas refineries to chemical installations – all the main sources of greenhouse gas emissions. (The agency says that the return of GHGRP will save $ 2.4 billion in regulatory costs, and that the program is “nothing more than bureaucratic administrative formalities that do nothing to improve air quality”.)))
Joseph says he closes this program with hamstrings “the basic practical capacity of the government to formulate climate policy”. Understand how new emission reduction technologies work or monitor decarbonizational industries and which are not “is extremely difficult to do if you do not have this data”.

The data collected by the GHGRP, which is accessible to the public, underpins a large part of the federal climate policy: understanding which sectors contribute which types of emissions are the first step in the training of strategies to reduce these emissions. These data are also the backbone of a large part of the international American climate policy: the collection of data on greenhouse gas emissions is mandated by the United Nations Framework Convention on Climate Change, which underpins the Paris Agreement. (While the United States has left the Paris Agreement for the second time on the first day of Trump’s second term, it remains – without danger – part of the UNCCCC.) The data collected by the GHGRP is also crucial for local and local climate policies, helping political decision -makers outside the federal government of local pollution, objectives of reduction of form emissions and the increase in federal government.
There is a certain hope that non -governmental actors could help. In recent years, various groups have intensified at the table to help calculate greenhouse gas emissions from sources in the United States and nationally. These groups use a mixture of federal, state, industrial and private data – from databases in the petroleum and gas industry to public and private satellites to federal data like what EPA provides – to create tools that help decision -makers and the public to understand where greenhouse gas emissions come from and how they have an impact on people in various ways. Technology has also grown and limits, because artificial intelligence models become more advanced both in monitoring and modeling emissions from different sources.
In the days following the announcement of the EPA, the groups that collect and model the data on emissions indicate that they provide calls from various stakeholders trying to find solutions if the EPA revokes the program. Goffman, who left EPA at the start of this year, says that there are staff within the agency who seeks to “connect or be part of university efforts” to continue collecting data.
One of the most publicized efforts to model non -governmental emissions is a coalition called Climate Trace, which was founded in 2019, following a Google donation, to observe global emissions using satellites. The group, which has since grown up over 100 collaboration organizations, has developed a multitude of AI models which they associate with data from various sources to follow and model emissions from around the world.
Trump’s EPA attacks its own power to fight climate change
There is a dark timing, explains the co -founder Gavin McCormick, by moving the EPA to put an end to the GHGRP after the climatic trace built its models by relying so strongly on EPA data. “We started this project on the thesis that America has the best monitoring of the world’s emissions, and other countries could reduce emissions more quickly if they presented themselves to the same quality as America,” said McCormick. “We have just spent five years building this AI system to try to allow other countries to have an approximation of the same system as America A.”
It is not only the climate that is concerned about the future of this data: there is an important interest in continuing to collect national data on greenhouse gas emissions. It is not because the American government is no longer invested in monitoring climate change that the rest of the world is on board. Oil and gas companies with facilities in the United States, for example, always have a financial interest in keeping traces of their emissions if they sell other markets, such as Europe, which is starting to impose strict methane requirements on imported gas in the block.
“Our phones have exploded in the past ten days about the last ten days, of people who say:” Should we start to realize now? ” You are not an official source, but you are the closest thing, ”explains McCormick. “It is not easy for me that we are the right vehicle for that. But there are very clear commercial interests for the reasons why companies would like to continue to report even if they are not.”
Private industry data could also be used to help follow greenhouse gas emissions and even cover certain emissions that are not captured in EPA data. The Rocky Mountain Institute, for example, a non -profit organization that works on market -based climatic solutions, manages an index based on private industry data which follows the emissions of the entire oil and gas production cycle. (RMI is part of the Climate Trace Coalition.) These private data allow this index to make an overview of the industry emissions that GHGRP may have missed or sub-chess, including the calculation of emissions from sources that do not meet the threshold for reports.
However, all the wired experts spoke at the end of the end of the GHGRP data collection, the efforts of the United States to measure and fight against greenhouse gas emissions, regardless of the quality of non-federal options. There are a myriad of difficulties faced with any organization that tries to assume this monumental task.

“If the EPA stopped demanding it, it is quite possible that the states continue to do so,” explains Gurney. But, he said, “there is no [other] Central warehouse to make the snack. Fifty entities transforming data files, which are massively complex, is only a huge business. EPA plays a role as important as this type of data arbiter, ensuring that everything is in accordance with standardization. This is the key for the rest of us, frankly, not having to do it ourselves, which would be roughly a prohibitive barrier so that we can understand this amount of data. »»
There are many different ways to calculate emissions; The techniques used to collect and model data can also differ between the different organizations and experts. Gurney, for example, was a vocal critic of the way in which Climate Trace designs his models. The requirements to declare the pollution of EPA, on the other hand, are also supported by law: “a non -governmental entity cannot really require this”, explains Goffman.
There is also an open question to find out if non -governmental estimates could hold legally, especially if a policy formed using these estimates is challenged before the court. In Louisiana, a law adopted last year seriously restricted the capacity of communities to use low -cost emissions monitoring to follow air quality and file complaints or prosecution concerning emissions; Air monitoring must now be carried out only by tools approved by EPA. (The groups that plead for communities living near oil and gas facilities have filed a complaint in May, claiming that the tools are prohibitive for local defenders and affirming that the law is a “blatant violation of rights of expression of community members to use their own surveillance of independent air pollution to relaunch alarms on fatal chemicals released in their own homes and schools.”).
This law “really returned to the house that it is only a scientific question and to make the data, and partly a question partly to lightness at the age of use”, explains McCormick.
