This document discusses potential trade barriers related to climate change. It analyzes the Waxman-Markey Bill, which proposes border tax measures for imports into the US from countries that do not regulate greenhouse gas emissions. The document examines India's trade with the US and identifies sectors that would be most affected by such border taxes, such as precious metals, apparel, machinery, and organic chemicals. It outlines methods used to estimate sectors' greenhouse gas emission levels and potential impacts on India's export revenues. While the bill may not pass, the analysis identifies industries vulnerable to future climate-related trade barriers.
