American Manufacturers Are Among the Cleanest in the World. Let’s prove it.

U.S. manufacturers have a compelling environmental story. American companies produce goods that emit 40% less carbon dioxide (CO2) than the global average for the same products.
The American steel industry, for example, has the lowest CO₂ emissions per ton of steel produced of any of the major steel-producing countries and accounts for just 1-2% of U.S. greenhouse gas (GHG) emissions. Globally, the steel industry emits around 8% of total world GHG emissions.
The American steel industry, and the manufacturing sector as a whole, have made significant investments in cleaner and more sustainable production processes. With these innovative technologies, we are committed to further reducing our environmental impact.
But unless companies overseas do the same, American manufacturing’s commitment to sustainability will put us at a disadvantage.
This is because the U.S.’ higher environmental performance comes with costs that many of our competitors are exploiting to capture global market share.
Read the full article from RealClear Energy, including information about a policy initiative the Senate Environment and Public Works Committee is considering called “Providing Reliable, Objective, Verifiable Emissions Intensity and Transparency” (PROVE IT) Act, to create an official source to verify the superior carbon efficiency of vital American industries, like steel.

Does steel provide a sustainable option for bridges?
Steel is the most recycled material on the planet. Some of the sustainable advantages of steel include:
- Steel from a disassembled bridge can be used again for another project.
- Steel bridges can last 100 years or more, with minimal maintenance over their long service lives.
- The high strength of steel permits longer spans, which minimizes disruption to underlying habitats.
- Steel is highly resistant to extreme natural disasters such as earthquakes.
- The American steel industry has achieved a 31 percent reduction in energy intensity and a 36 percent reduction in greenhouse gas intensity since 1990.
