ArcelorMittal, the world’s largest steelmaker, recently introduced a program to offer certificates to customers that certify they have reduced their carbon footprint through the steelmaker’s own greenhouse-gas emission reductions. It’s the first such carbon-offset program by a major steelmaker. While it is focused on the Luxembourg-based company’s European customers, the certificates could be used by North American contractors and owners, as Canada already has a carbon tax and some U.S. entities require reporting.
The program, XCarb green steel certificates, allows buyers to purchase vouchers along with steel orders that can show an offset of Scope 3 carbon dioxide and other greenhouse gas emissions. Scope 3 emissions can come from anything in a company’s value chain, such as steel used in buildings, according to the GHG Protocol used by many governments to report emissions worldwide. The “green steel” will be produced by ArcelorMittal’s plants in Europe that use technologies such as hydrogen direct-reduced iron or electric-arc furnaces (EAFs), which use electricity that can be certified as coming from renewable sources such as wind turbines, to produce steel. Producing coking coal through biomass and capturing emissions for use in chemical production also will be used to certify the green steel.
“作为一家公司，我们已申请（Europen Union Green Deal）资金，以支持我们想在法国，德国和其他地方继续进行的一些资本密集型项目。”18luck官网欧洲欧洲。“因此，欧盟的管道已经得到支持，我们已经在汉堡等地方与其他地方合作，与那里的城市当局一起，他们通过构建我们的氢网络来支持我们'需要。”
与经过认证的回收钢计划一起，这些证书是整体策略的一部分，ArcelorMittal希望将使它能够到2050年将其排放量减少到零，作为巴黎气候协定的一部分。专注于建筑科学的Arcelormittal Steligence部门首席执行官Olivier Vassart表示，没有一个钢铁厂会创建该计划中认证的产品。
"The amount of certificates which are available will be aligned through the global progress we achieve in each of the individual mills," he explained. "The physical steel that arrives at your door could come from Dunkirk in France. It could come from Spain, it could come from Germany. That's why we're operating at a Europe-wide level because that's the way the whole company operates."
The green and recycled-steel product lines will comprise only 2% of ArcelorMittal’s total annual steel production by the end of 2022—roughly 600,000 metric tons—but ArcelorMittal plans to expand production to a target of 10% of its total steel products by 2025-30.
Arcelormittal首席执行官Satiya Mittal在10月表示，该公司将为欧洲贸易计划创新基金申请，这些项目可以帮助到2050年达到其脱碳目标。Evans表示，ETS资金以及其他来源将资助该公司的各种技术项目，旨在实现这一目标，以18luck官网实现这一目标。目标。
“It’s a challenging commitment,” says Kate Simonen, executive director of the Carbon Leadership Forum and professor and chair of the department of architecture at the University of Washington. “That’s why it’s hard to imagine all of the industries being able to decarbonize, but there are road maps and pathways within each sector that are getting there.
“Leading global companies are developing frameworks by which they are setting a pathway to at least move toward that direction and invest in that,” Simonen adds.
She points to states such as California, which has made purchasing departments for all state projects report a carbon footprint as a possible use of the green certificates by U.S. steel buyers.
"We need to look at the legal framework in the different regions of the world," Vassart says, "but, for the moment, the system has been tailor-made for European regulation. It is linked to how companies here are calculating their CO2 footprint."
代表结构性钢制造商的美国钢结构研究所（American Steel Construction）被问及Arcelormittal的倡议时，吹捧了美国EAF钢铁生产能力。
AISC政府关系与可持续性主管Max Puchtel说：“联邦政策最有效地减少钢铁制造的排放是强大的购买规定。”“这是由于我们充足的低碳能源供应，充足的废品供应以及专注于EAF钢制。”
He also said that end users are looking for ways to demonstrate carbon reductions in their projects, whether by regulation or customer requirement.
美国钢铁协会represents U.S. steelmakers, did not address questions about compliance with government emissions mandates but also touted U.S. EAF capacity and the high percentage of low-emitting natural gas used in U.S. mills. AISI also says U.S. steelmakers are doing their own research to produce the technology that can eventually produce decarbonized steel.
“Work is underway on innovations for increased use of renewable energy in steel production and advancements in domestic production using direct-
reduced iron and hot-briquetted iron, which use natural gas as a reductant, in place of pig iron in both integrated and EAF steelmaking," says Kevin Dempsey, AISI president and CEO.
瓦萨特说，尽管最终脱碳的途径仍然为Arcelormittal奠定了重大障碍，以清理公共政策授权和他的创新，例如他的公司可以帮助达到2050年的终点线。
"We know the road ahead is not straightforward," he says. "With cross-sector collaboration and supporting public policy like we have to scale up the technology and ensure the largest-scale deployment of clean energy infrastructure, we know that we can transition to carbon-neutral steelmaking and play a really big role in helping Europe to achieve its climate ambition."
