Question

When companies discuss sustainability, why is the focus on carbon dioxide (CO2)?
A) It is easier to completely eliminate CO2 than to develop sustainable technology.
B) It is more difficult to measure carbon in the solid form than the gaseous form.
C) It is the only gas that is causing climate change and impacting sustainability
D) It is a greenhouse gas that is easily detechable and stays in the atmosphere for centuries​

Answer 1

Answer:

Carbon dioxide(CO2) is a major reason for the increasing global warming. It is a greenhouse gas. 4. Increased Carbon dioxide traps the heat and does not allow heat to escape which causes major changes in the climate.

Answer 2

When companies talk about sustainability, they usually focus on carbon dioxide ($CO_2$) the reason behind this is - "It is a greenhouse gas that is easily detectable and stays in the atmosphere for centuries​"(Option D).

• Environmental sustainability, according to the United Nations (UN) World Commission on Environment and Development, means acting in a way that guarantees future generations have the natural resources they need to live a life that is equal to, if not better than, present generations. So during their talks about this obviously the greenhouse problem comes to light.
• The principal greenhouse gas emitted by human activity is carbon dioxide($CO_2$) . The greenhouse effect is caused by a gas that absorbs and emits radiant energy in the thermal infrared spectrum. The sun heats the earth's atmosphere during the day. Heat is radiated back into the atmosphere as the earth cools at night. The heat is absorbed by the greenhouse gases in the earth's atmosphere throughout this process. This is what keeps the earth's surface warm, and what allows living things to survive on the planet. However, the earth's temperature has risen significantly as a result of higher amounts of greenhouse gases. This has had a number of significant consequences.
