A New Website Backed By Al Gore Tracks Big Polluters By Name

A new global tracker created by the nonprofit Climate Trace is helping to make clear exactly where major greenhouse gas emissions are originating. According to NPR, the interactive map "uses a combination of satellites, sensors and machine learning to measure the top polluters worldwide." From the report: It observes how much greenhouse gases -- carbon dioxide, methane and nitrous oxide -- are being emitted at specific locations, such as power plants and oil refineries. Former Vice President Al Gore, who is a founding member of the initiative, said it is meant to serve as a more reliable and accurate alternative to companies self-reporting their emissions estimates. "Cheating is impossible with this artificial intelligence method, because they would have to somehow falsify multiple sets of data," he told NPR's Michel Martin on All Things Considered. The emissions tool employs over 300 satellites; sensors on land, planes and ships; as well as artificial intelligence to build models of emission estimates. Right now, it tracks about 72,000 of the highest emitting greenhouse gas sources. That includes every power plant, large ship and large plane in the entire world, Gore said. And that's just the beginning. By next year, Gore hopes to be tracking millions of major emitting sites. "We will have essentially all of them," he said. Gore said 75% of the world's greenhouse emissions come from countries that have made pledges to become carbon-neutral by 2050. "Now that they know exactly where it's coming from, they have tools that will enable them to reduce their emissions," he told NPR. He added that the database, which is free and accessible online, can help inform countries about how much pollution is being emitted by the companies they are working with or considering working with. It is not enough for companies to self-report, he said. For instance, Climate Trace found that the oil and gas industry has been significantly underreporting its emissions. That doesn't mean companies were intentionally cheating, Gore added. However, he said underreporting prevents governments and the public from staying on track with their net-zero pledge. Six regional governments in Mexico, Europe and Africa have already entered into working agreements for using the tool, Gore said.
