As main customers of coal-based metal, U.S. and E.U. automakers can catalyze marketplace for inexperienced steelmaking

The auto business can remove greater than 95% of greenhouse gasoline emissions from producing the metal for passenger automobiles by switching to fossil fuel-free metal, in response to a brand new report launched at the moment by the Worldwide Council on Clear Transportation (ICCT).

“Main metal, a crucial part of at the moment’s auto sector provide chain, is a worldwide driver of greenhouse gasoline emissions and a hazard for the well being of native communities, because of the business’s heavy reliance on coal. Already, steelmakers are piloting fossil fuel-free applied sciences that may remove 95% of the emissions from producing metal within the common automobile” stated Anh Bui, a researcher on the ICCT. “As automakers spend money on methods to fulfill bold local weather targets, prioritizing fossil-free metal would slash emissions and create a strong market sign.”

The report, Applied sciences to cut back greenhouse gasoline emissions from automotive metal in the US and the European Union, compares methods for automakers to cut back steel-related emissions from automobiles.

A lot of the greenhouse gasoline emissions from the lifetime of automobiles comes from the gasoline and diesel they burn. However automobile manufacturing causes important emissions too – and as we make progress in main international locations swap over to electrical automobiles operating on an more and more decarbonized grid, these manufacturing emissions develop in significance. To realize a totally internet zero GHG transportation sector by 2050, it is going to be essential to drastically scale back the embodied emissions in key supplies like metal and batteries.

Procuring main metal with out fossil fuels is the strongest attainable pathway to cut back steel-related emissions from automobiles – and this might be completed at scale within the U.S. by the top of the last decade. Collectively, automakers are among the many largest consumers within the metal market in each the U.S. and EU. In 2022, the auto business consumed 26% of the 82 million metric tons of metal produced within the U.S., and 60% of all home main metal. In the identical yr, 17% of the 136 million metric tons of metal produced in Europe went to the auto business, and 24% of all home main metal. As a result of main metal business’s heavy reliance on coal, metal is chargeable for as much as 27% of embodied emissions in a typical inner combustion engine automobile.

“Procuring main metal made with inexperienced hydrogen and renewable electrical energy as a substitute of fossil fuels takes an enormous chunk out of provide chain emissions — but it surely’s additionally very cost-effective for automakers,” stated Marta Negri, an affiliate researcher on the ICCT. “For lower than 1% of car prices, automakers may also help transition one of many dirtiest industries on the planet towards clear vitality, present clear air to native communities, and meet their local weather targets.”

A lot of the greenhouse gasoline emissions from the lifetime of automobiles comes from burning gasoline and diesel. However automobile manufacturing additionally generates important emissions. Because the world transitions to electrical automobiles powered by an more and more decarbonized grid, these manufacturing or embodied emissions develop in significance. To realize a totally internet zero GHG transportation sector by 2050, it is going to be essential to drastically scale back the embodied emissions in key supplies like metal and batteries.

Metal manufacturing is among the most vitality and emission intensive industries worldwide, relying closely on fossil fuels, particularly coal, in main manufacturing. In automobile manufacturing, metal is probably the most used materials by mass, usually making up between 50% and 66% of the automobile, relying on the mannequin, section, and powertrain kind.

Given the automotive business’s substantial metal consumption, automakers could also be uniquely suited to drive demand for fossil fuel-free metal and affect the metal business transition away from coal-based metal manufacturing.

This evaluation examines the power of automotive industries in the US and the European Union to cut back GHG emissions of automotive metal by way of:

• Discussing present metal manufacturing pathways and related GHG emissions
• Describing pathways to supply fossil fuel-free metal
• Exploring different modes to cut back metal demand in automobiles
• Evaluating GHG emission discount potential for inner combustion engine automobiles (ICEVs) and battery electrical automobiles (BEVs) in the US and the European Union
• Summarizing the opposite elements vital for the transition to inexperienced metal

The analysis arrives on the following key outcomes:

• The auto business can remove greater than 95% of greenhouse gasoline emissions from producing metal for passenger automobiles by switching to fossil fuel-free metal. Doing so would cut back general automobile manufacturing emissions by as much as 27%.
• Utilizing fossil fuel-free metal in automobile manufacturing will increase value by $100–$200, or lower than 1% of the worth of a median new automobile
• Fossil fuel-free main metal manufacturing applied sciences exist already, and manufacturing capability can improve, however not with out commitments from consumers.
