Revealed: the 20 firms behind a third of all carbon emissions
The top 20 companies on the list have contributed to 35% of all energy-related carbon dioxide and methane worldwide, totalling 480bn tonnes of carbon dioxide equivalent (GtCO2e) since 1965.

Those identified range from investor-owned firms – household names such as Chevron, Exxon, BP and Shell – to state-owned companies including Saudi Aramco and Gazprom. Chevron topped the list of the eight investor-owned corporations, followed closely by Exxon, BP and Shell. Together these four global businesses are behind more than 10% of the world’s carbon emissions since 1965.

Canaries As Poisonous Gas Detectors
n the late 1890s, [John] Haldane began experimenting on small animals like white mice and canaries [to detect carbon monoxide]. Small animals have faster metabolism rate, and hence show the effects of carbon monoxide poisoning much earlier even in the presence of small quantities of the noxious gas. Canaries are especially good at detecting toxins in the air because of their specialized respiratory system.
