Google has made 'substantial' donations to climate change deniers, according to reports.
Although the company says it supports political action on the climate breakdown, The Guardian has listed groups described as 'beneficiaries of [Google's] political giving' which take an anti-environmental stance.
These take the form of groups 'that have campaigned against climate legislation, questioned the need for action, or actively sought to roll back Obama-era environmental protections'.
A notable inclusion is Washington D.C.-based think tank Competitive Enterprise Institute (CEI), which persuaded Donald Trump to abandon the Paris agreement.
Another is the State Policy Network (SPN), some of whose members have created what they call a 'climate pledge' which states that there 'is no climate crisis'.
Google has defended the contributions by saying that 'collaborating' with organizations does not equal 'endorsing their entire agenda'.
"Our position on climate change is similarly clear. Since 2007, we have operated as a carbon-neutral company and for the second year in a row, we reached 100 percent renewable energy for our global operations," a spokesperson added.
