Reducing emissions of the socalled greenhouse gases, such as CO 2 or CH 4 is not the only solution to curb the greenhouse effect International organisations also agree on the following recommendations Use renewable energy Use public transport and other nonpolluting means, such as electric vehicles or bicyclesThe answer may not be as clear as one might assume, because the top emitters change depending on how the data is collected and whatAs is the case with CO2 emissions, China is the world's largest emitter of greenhouse gases today It emits around twice as much as the United States, which is the second largest emitter This is followed by India, Indonesia and Russia However, this is not the case when we adjust for population and look at per capita emissions

A community wide inventory and a " Carbon " is shorthand for greenhouse gas emissions, including CO2, methane, nitrous oxide and Fgases These gases are released by many different types of activity –Let's consider the principal GHGs one at a time, starting with water vapor, the most abundant greenhouse gas in the atmosphere according to NOAA's National Climatic Data Center (NCDC) Water Vapor Carbon Dioxide (CO 2) Methane (CH 4) Nitrous oxide (N 2 O) Fluorinated Gases (HFCs, PFCs, SF 6) References and Resources

It provides data based on a productionbased accounting of emissions of carbon dioxide, methane, nitrous oxide, perfluorocarbon, hydrofluorocarbon, and sulfur hexafluoride (meaning emissions within the territory of the given country), compiled by the World Resources Institute and divided by the population estimate by the United Nations (for July 1) of the same yearFigure 71 Rise in the concentrations of greenhouse gases since the 18th century As we will see in section 73, simple theory shows that a rise in greenhouse gases should result in surface warming;That's because greenhouse gases are trapping heat in the lower atmosphere Climate models that include solar irradiance changes can't reproduce the observed temperature trend over the past century or more without including a rise in greenhouse gases References IPCC Fifth Assessment Report, 14 United States Global Change Research Program, "Global Climate Change Impacts

Today, about a fifth of global carbon emissions come from raising farm animals for meat For example, as cattle digest food, they burp, releasing methane, a powerful greenhouse gas, and their manure releases the greenhouse gases carbon dioxide and nitrous oxide And forests, which take carbon dioxide out of the air, are often cut down so that cattle have space to grazeAdditional trace gases produced by industrial activity that have greenhouse properties include nitrous oxide (N 2 O) and fluorinated gases (halocarbons) The latter includes sulfur hexafluoride, hydrofluorocarbons (HFCs), and perfluorocarbons (PFCs) Just 100 companies are responsible for more than 70 per cent of global greenhouse gas emissions over the last three decades, new research has revealed The Carbon Majors Report, from the Carbon

Some of the greenhouse gases include carbon dioxide, nitrous oxide, perfluorocarbons, sulfur hexafluoride, ozone, water vapor and a few others The process of creating electricity, running cars, using landfills and making chemicals are some of the top ways we are releasing more and more greenhouse gases into the atmosphere The good news is, according to the EnvironmentalOn the other hand, if our goal is to stabilize longterm greenhouse gas concentrations, we would be better served by focusing purely on CO 2 emissions Figure 121 Greenhouse Gas Emissions By Gas 04 Click for a text description of Greenhouse Gas Emissions by Gas 04 Carbon dioxide/CO 2 fossilfuel use 566%; Greenhouse gases are components of the atmosphere that contribute to the greenhouse effect Some greenhouse gases occur naturally in the atmosphere, while others result from human activities such
