The most accurate carbon calculators implement consumption-based equations. This inclusion helps pinpoint the scale of the issues, and the necessary means to further reduce one's carbon footprint. According to the Berkeley Institute Of The Environment, a typical household in the United States emits about 50 tons of greenhouse gases per year. This shocking number takes into account consumption of energy, fuels, goods and services, and relevant emissions related to government and industrial activities. The global average for greenhouse gas emissions per year is only 10 tons per household 5, which means that the average U.S. household produces 400 percent more carbon emissions than the average global household.
If diligent action is not taken to curb carbon emissions and greenhouse gases produced by human activity, the average temperature of the Earth's surface could increase by 3.2 to 7.2 degrees Fahrenheit by the year 3000. Although the ultimate effects of increasing temperatures are unknown, we are already beginning to see the effects of climate change. Some of these present environmental effects include changing rainfall patterns, a drastic shift in snow and ice levels, and rising sea levels 6.
