A new interactive map with data on greenhouse gas emissions from cargo ships, landfills, oil fields, livestock feedlots and more can help businesses, investors and policymakers know where the sources of pollution are in the world. World that should be selected for decision making.
The density of the largest sources of pollution on the map is in China, South Korea and Japan. This result is also close to available data from carbon dioxide (CO2) emissions for which China, USA, India, Russia and Japan are in the top 5.
The most polluting place in the world is in the USA, an oil field in Texas.
There are more than 70.000 individual sources of climate pollution listed in this new map drawn from what is now the world's largest and most detailed database of greenhouse gas emissions.
This map includes more than 100 Portuguese entities.
Among these, Galp's Sines refinery is the leader in terms of pollution in our country (in position 1.634 in the world ranking). Lisbon and Porto airports are also among the most polluting. Several cement factories that have not yet adjusted their manufacturing process, Cimpor in Alhandra, Cimpor in Souselas, cement factory in Marinha Grande, Secil in Setúbal, Cimpor in Loulé. The Portuguese Top 10 ends with Faro airport and Siderurgia Nacional.
Secil launched the first concrete with zero CO2 emissions, according to information released on November 2, 2022.
“You can't manage emissions if you don't know what they are,” said Gavin McCormick, founder and CEO of WattTime, an environmental technology organization that is part of a coalition of organizations, data scientists, researchers and artificial intelligence experts. , designated Climate Trace, who built the map. The database includes everything from cargo ships to landfills — the biggest sources of climate pollution in energy production, transportation, waste, agriculture and heavy industry.
Countries are often slow to release their emissions data, so information can be out of date and even official emissions reports can be inaccurate. Climate Trace makes the most detailed calculations possible for each source of pollution. In livestock feedlots, for example, where there are emissions of methane, a potent greenhouse gas, they use satellite data to measure the size of the facility and then use an algorithm to identify whether it is a dairy facility or a beef facility and to estimate the number of livestock. Finally, it is multiplied by the estimated emissions per head of cattle for that location.
The Climate Trace team used sophisticated models and satellite data to quantify polluting emissions.
“Identifying sources of pollution that are of high intensity and volume gives businesses, investors, policymakers and consumers a clear indication of which assets should be directed first towards emissions reductions or decommissioning,” says Deborah Gordon, Senior Director from the non-profit organization RMI, which has led work in the oil and gas sector for Climate Trace.
This team admits that polluting entities sometimes report values lower than the real ones, which are even three times lower.
“Investors looking to reduce emissions in their portfolio can use this information to estimate the carbon footprint of the facility they plan to invest in,” says McCormick.
This inaugurates “a new era of radical transparency to track emissions”, said UN Secretary General António Guterres and goes on to say that “it becomes more difficult to “greenwash” or, to be clearer, to cheat”.
