A new study from the Colorado-based Climate Accountability Institute suggests that all but seven of the 90 companies found to have caused the climate crisis deal in oil, gas and coal – and half of the estimated emissions were produced just in the past 25 years. Some of the top companies are also funding climate change denial campaigns. This visualization by The Guardian allows the users to understand which are the top 90 producers and how they are doing it.
