Huge Undeclared Gas Faring Emissions
Major oil companies are not declaring a significant source of greenhouse gas emissions. The BBC found millions of tonnes of undeclared emissions from gas flaring at oil fields where BP, Eni, ExxonMobil, Chevron and Shell work.
Flared gases emit a potent mix of carbon dioxide, methane and black soot which pollute the air and accelerate global warming.
The BBC has also found high levels of potentially cancer-causing chemicals in Iraqi communities near oil fields where there is gas flaring. These fields have some of the highest levels of undeclared flaring in the world.
