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).
Trends. Since 1751 approximately 337 billion metric tonnes of carbon have been released to the atmosphere from the consumption of fossil fuels and cement production. Half of these emissions have occurred since the mid 1970s. The 2007 global fossil-fuel carbon emission estimate, 8365 million metric tons of carbon, represents an all-time high and a 1.7% increase from 2006.
