Modern vehicles contain more software and tech than ever, but they're still essentially steel on wheels. Steel is the most common material in cars; it's found in everything from the chassis to the wheels, making up at least half of a vehicle by weight. The automotive industry accounts for about 16% of global steel consumption, per a 2023 Greenpeace report. Steel is responsible for more than 30% of a vehicle's material emissions, the report said, and the percentage of automotive-life emissions from materials is slated to rise to 60% by 2040 as electrification eliminates tailpipe emissions. That is why climate advocates say the auto sector is uniquely positioned to push for decarbonization in the steel industry, which accounts for about 7% of global carbon emissions. That's the thinking behind a new campaign from Public Citizen, a nonprofit progressive consumer rights advocacy organization, that demands that the auto industry step up its game on green steel, or steel that's made without fossil fuels. "The idea is that by encouraging top automakers to make these changes to their supply chains, it will catalyze major action by other automakers—and ideally, wider heavy industry," Carly Oboth, senior supply chain campaigner for Public Citizen's climate program, told Tech Brew. "If [automakers] can signal their demand for green steel," she added, "it will encourage and convey to steel producers that they need to invest in the technology and they need to use fossil-free steel."
