Two thirds of greenhouse gases caused by just 90 companies

Ninety companies produced almost two-thirds of greenhouse gases released since the Industrial Revolution, according to new research.

Scientists at Climate Accountability Institute in Colorado found that a range of companies such as Chevron, Exxon and BP as well as government and state run firms are within the group of 90. The companies, who mainly produce oil, gas and coal, have produced 63% of the global emissions of industrial carbon dioxide and methane between 1751 and 2010.

The researchers also found that half of the estimated emissions were produced in the past 25 years.
