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).
Human emissions of carbon dioxide are small compared to those of natural carbon sources. In 2008, fossil fuel carbon dioxide emissions contributed about 8.7 billions tons of carbon to the atmosphere per year, and this number continues to rise. Land use change was responsible for estimated net emissions of 1.5 billion tons of carbon per year over the last 15 years.
