Question: When companies discuss sustainability why is the focus on carbon dioxide?

The focus on carbon dioxide (CO2) when companies discuss sustainability is primarily due to its significant role in climate change. CO2 is a greenhouse gas that contributes to the trapping of heat in the Earth's atmosphere, leading to global warming. It is the most prevalent and long-lasting greenhouse gas emitted by human activities, such as burning fossil fuels for energy production and transportation. By addressing CO2 emissions, companies aim to reduce their carbon footprint and mitigate the environmental impact associated with climate change, demonstrating their commitment to environmental stewardship and a sustainable future.
