Carbon dioxide is everywhere: in the air, rising from cracks in the ocean floor, and in your soda can. Now it's showing up in the news! Find out why carbon dioxide is such a hot topic, and why it's going to be around for a long, long time.

This interactive visualization provides information in text, graphic, and video format about renewable energy technologies. Resource in the Student's Guide to Global Climate Change, part of EPA Climate Change Division.

Climate Change 2014: Mitigation of Climate Change

On April 15 in Berlin, Germany, the Intergovernmental Panel on Climate Change approved and released Working Group III's Fifth Assessment Report - a comprehensive assessment of all relevant options for mitigating climate change through limiting or preventing greenhouse gas emissions, as well as activities that remove them from the atmosphere.

This video is one of a series from the Switch Energy project. It reviews the environmental impacts of various energy resources including fossil fuels, nuclear, and renewables. CO2 emissions as a specific environmental impact are discussed.

U.S. Submits 2014 Climate Action Report to UNFCCC

The U.S. Department of State has submitted its 2014 Climate Action Report to the United Nations Framework Convention on Climate Change (UNFCCC). The report details actions the United States is taking domestically and internationally to mitigate, adapt to, and assist others in addressing climate change.

Voluntary Reporting of Greenhouse Gases-Carbon Management Evaluation Tool

A decision support tool for agricultural producers, land managers, soil scientists and other agricultural interests, COMET-VR estimates soil carbon changes for management alternatives for a ten-year projection period within each Major Land Resource Area (MLRA) allowing users to estimate soil carbon sequestration on a parcel of land. The COMET-VR tool is provided by the U.S. Department of Agriculture.

This as a 2-part activity in which students study the properties of CO2 in a lab and then use Web resources to research different types of carbon capture. A video lecture accompanies the activity.

U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2008

The U.S. Agriculture and Forestry Greenhouse Gas Inventory: 1990-2008 (USDA GHG Inventory) is a comprehensive assessment of greenhouse gas emissions and sinks in U.S. agriculture and forests. The USDA GHG Inventory provides extensive, in-depth emissions and sinks estimates for livestock, cropland, and forests as well as energy consumption in livestock and cropland agriculture.
