The more you know about carbon and carbon emissions, the better equipped you can be to make a positive difference. In this article, we'll help explain what carbon emissions are and why they matter as well as share ways to reduce your own carbon footprint.
Carbon dioxide emissions are the primary driver of global climate change. It's widely recognized that to avoid the worst impacts of climate change, the world needs to urgently reduce emissions. But, how this responsibility is shared between regions, countries, and individuals has been an endless point of contention in international discussions.
Are you wondering what carbon emissions are and why they’re so important? Learn about the main sources of emissions and how you can do your part today.
CO2 and other greenhouse gases like methane and nitrous oxide are emitted when we burn fossil fuels, produce materials such as steel, cement, and plastics, and grow the food we eat. If we want to reduce these emissions, we need to transform our energy systems, industries, and food systems.
Carbon dioxide (CO 2) is an important heat-trapping gas, also known as a greenhouse gas, that comes from the extraction and burning of fossil fuels (such as coal, oil, and natural gas), from wildfires, and natural processes like volcanic eruptions.
Total greenhouse gas emissions are the sum of emissions of various gases: carbon dioxide, methane, nitrous oxide, and smaller trace gases such as hydrofluorocarbons (HFCs) and sulfur hexafluoride (SF6). How much does each gas contribute to global greenhouse gas emissions?
If global energy demand continues to grow rapidly and we meet it mostly with fossil fuels, human emissions of carbon dioxide could reach 75 billion tons per year or more by the end of the century. Atmospheric carbon dioxide could be 800 ppm or higher—conditions not seen on Earth for close to 50 million years.
Over the past few years, we’ve received a lot of questions about carbon dioxide — how it traps heat, how it can have such a big effect if it only makes up a tiny percentage of the atmosphere, and more.
Greenhouse gas emissions are certain gases released into the atmosphere that create a “greenhouse effect”. Heat becomes trapped and global temperatures rise.
Carbon dioxide, a key greenhouse gas that drives global climate change, continues to rise every month. Find out the dangerous role it and other gases play.
