Carbon emissions resulting in climate change pose increasingly growing material risks to society and corporations. These impacts will reach into every supply chain, capital market, and customer base.

To address these risks and shareholder concerns, companies should establish accredited science-based greenhouse gas reduction targets that adhere to the Paris Agreement and limit global warming to 1.5° Celsius from pre-industrial levels.
