EN Environment Our decarbonization strategy We are committed to developing long-term sustainable business by reducing our environmental footprint within our communities and value chain; working with partners and peers to address the climate change challenge and transition to a carbon neutral economy. We aim to achieve this target by using a higher proportion of recycled steel scrap in the metallic mix, investments to increase energy efficiency, and the use of renewables for part of our energy requirements as well as the development of technologies involving the use of hydrogen and carbon capture. To accelerate the fulfilment of these targets, we are implementing an internal carbon price of USD 80/ton for evaluating investments, and more generally in our operations. 30% by 2030 intensity reduction target in CO₂ tn/tn steel 82% recycling content in our steel 98.9% material efficiency at steel making sites 6 Environmental Product Declarations Our areas of action Increase scrap use Recycling scrap metal preserves non-renewable resources, using less energy with fewer greenhouse gas emissions. We have achieved recycling content levels of 82% in our steel using electric arc furnaces to recycle steel scrap. Energy efficiency & waste energy recovery We are seeking to integrate energy transition and digital transformation initiatives using carbon-efficient sources of energy, adopting the best available technologies. Renewable energy We aim at reducing the intensity of CO₂ emissions by increasing the use of clean electricity. Electric arc furnaces for circular, low-emission steel Today, the steel produced at our Dalmine, Siderca, Tamsa and Silcotub facilities has recycled content of 82% calculated according to ISO 14021 standards, thanks to the use of electric arc furnaces (EAF). Together, these mills emit 1.10 ton of CO₂ per ton of steel in scopes 1, 2 and 3. According to the worldsteel association, the industry's average is 1.83 ton of CO₂. We are committed and continue to work to reduce emissions at all levels of our operations. A manufacturing trial with green hydrogen As the first step in our Dalmine Zero Emissions initiative, we are launching the first industrial-scale project in Italy to decarbonize the steel sector by introducing green hydrogen into specific production processes. The project aims to generate hydrogen and oxygen through a 20 MW electrolyzer installed at Dalmine, adapting the steelmaking process to use green hydrogen instead of natural gas, significantly reducing steel direct emissions by up to 73%. LEARN MORE Investing in our operations We apply the best available technologies in all new lines, aiming at improving our performance beyond local applicable requirements. Air quality In 2019, we invested USD 27 million in our Tamsa facility in Mexico to upgrade the capture and treatment system for steel shop emissions, adding new filters and enhanced extraction capabilities. Reducing volatile organic compounds (VOCs) New efficiencies in the Finishing Line coating booth at the Bay City mill in Texas have optimized pipe varnish and cut waste. The Thermal Oxidizer destroys 90% of volatile compound emissions contributing to a more sustainable process. At Siderca mill in Argentina we moved from solvent to water-based products as part of a USD 2 million project. Reduce, Recycle, Reuse We continuously work to develop Reduce, Recycle, Reuse (3R) initiatives, from reducing single-use plastics to using biodegradable materials. At the Costa Volpino facility in Italy, high temperature fumes are used to dry out sludge from the waste water treatment plant, compacting the volume sent to disposal by 70%. In 2020 alone, we reused or recycled 5,800 tons of wood, 60,000 tons of scale and 260,000 tons of slag. LIFE CYCLE APPROACH Environmental Product Declarations Tenaris obtained the Environmental Product Declarations (EPD) for its OCTG, offshore and onshore line pipe products, structural tubes for offshore and onshore applications, power generation tubes and large vessels. EPDs disclose in a transparent, objective and standard way the environmental credentials of our products, measuring the impact of a ton of steel pipes in terms of air emissions, energy use, climate change, the recovery of co-products and water use. The Environmental Product Declarations are verified on an annual basis, updated in case of any significant change in the environmental performance and certified by an external body. EPDs comply with the rules of the International EPD® System and meet the requirements of ISO 14025. Below our EPDs. The ones about large vessels and power generation products are available upon request at the related product pages.
