Figure:CO₂ emissions for selected countries in 2007 and projected for 2030

There are concerns that increased carbon dioxide ( $\mathrm{CO}_{2}$ ) emissions are leading to changes in the global climate.

Identify one reduction strategy that the United States might use to achieve its projected change in $\mathrm{CO}_{2}$ emissions.

Identify one reduction strategy that the United States may use to achieve its projected change in CO2 emissions.
reduction of energy consumption/CO2 production through laws/taxes/education;
use of alternatives to fossil fuels;
$\mathrm{CO}_{2}$ removal though CCS;
afforestation / reducing rates of deforestation;

Marking guidance:

Accept any other reasonable suggestions, but they must be explicitly linked to reduction in C emissions ie not simply "improve public transport" or "recycling".
