Oil import and export developments pose a host of policy issues. Concerns about import dependence continue to generate interest in policy options to directly discourage imports or to reduce the need for imports by increasing domestic supply and decreasing demand. Rising exports at a time of rising prices has led to calls for policies to restrict such trade. The debate around the Keystone XL pipeline involves concerns about imports, exports, and the environment. The rising cost for fuels has led to calls for release of the Strategic Petroleum Reserve, meant to provide a short term policy option in case of supply disruptions. Policy options may entail various economic, fiscal, and environmental trade-offs.
