Non-profit organization Influence Map has released a report alleging that oil companies spent $114 million last year to prevent action being taken on climate change. The money was divided between publicity to mislead the public on the science and lobbying of politicians to prevent the passage of legislation. The estimate does not include contributions from other fossil fuel companies, and probably misses some under the table payments.
