If your project needs planning permission and you do the work without getting it, you can be served an âenforcement noticeâ ordering you to undo all the changes you have made. Itâs illegal to ignore an enforcement notice, but you can appeal against it.
In 2014, U.S. greenhouse gas emissions totaled 6,870 million metric tons (15.1 trillion pounds) of carbon dioxide equivalents. This total represents a 7 percent increase since 1990 but a 7 percent decrease since 2005 (see Figure 1).
Fossil-fuel dominated electricity generation in the United States and China has enormous environmental consequences. In 2007, 2.4 billion metric tons of carbon dioxide (CO2) were emitted from electricity generation in the United States, about 40 percent of the countryâs energy-related greenhouse gas (GHG) emissions.
