Long-term target: Gränges’ 2025 target is to reduce direct and energy indirect carbon emissions intensity (scope 1+2) by 25 per cent versus 2017. The company has also set a long-term target to reduce indirect carbon emissions intensity from purchased materials and services (scope 3) versus the 2017 baseline.
Total emissions of greenhouse gases
Note: Data for Gränges Americas’ 2017 scope 3 emissions has been restated due to updated data for primary aluminium use.
Note: Data for Gränges Americas’ 2017 scope 3 emissions has been restated due to updated data for primary aluminium use. Data for Gränges’ total 2016 scope 3 carbon intensity has been corrected due to a calculation error.
Emissions by category (scope 3)
Other emissions to air – dust
Note: Data for Gränges Americas’ dust emissions have been restated compared to data presented in the Annual report 2017, due to an update of the emission factors used.
Comment: The direct and energy indirect carbon intensity (scope 1+2) decreased by 6 per cent compared to 2017, driven by improved energy intensity and by a higher share of low carbon nuclear electricity, which replaced fossil fuel-based electricity in Gränges Americas. The carbon intensity for other indirect emissions (scope 3) decreased by 6 per cent compared to 2017, mainly driven by increased use of recycled aluminium replacing primary aluminium in Gränges Americas, and by improved material efficiency in Gränges Asia. Emissions of dust decreased compared to 2017 due to lower consumption of natural gas.
Reporting principles and definitions: Data is reported at regional level and consolidated annually at group level using common definitions and principles. Data for 2016 includes operations in the US.
Greenhouse gas emissions are presented as carbon dioxide equivalents. In accordance with the GHG Protocol, the definitions of the respective scopes are the following.
Scope 1 is defined as direct emissions from Gränges’ operations, which include production facilities, office buildings and company owned vehicles. Emissions are calculated based on fuel consumption and emission factors.
Scope 2 is defined as energy indirect emissions from the generation of purchased electricity and heat consumed by Gränges, in production facilities and office buildings. Emissions are calculated using specific data from Gränges’ electricity and heat suppliers.
Scope 3 is defined as other indirect emissions. These include emissions from extraction, production and processing of main purchased materials, fuel and energy related activities (not included in scope 1 or scope 2), upstream and downstream goods transportation as well as business travel. Fuel and energy related activities include production of fuels used in Gränges’ operations and in generation of purchased electricity. Emissions from producing primary aluminium are based on regional industry averages, and supplier data is used for purchased slabs and recycled aluminium. Emissions from producing fuels are based on regional industry data and emissions from transportation and business travel are based on specific data from Gränges’ transport routes.
Carbon intensity is defined as total emissions of greenhouses gases [tonnes CO2e] divided by the total packed products [tonnes].
Dust emissions are calculated either using local emission factors or based on continual measurements.
Other emissions such as nitrogen oxides, sulphur dioxide, oil and VOC are not reported as methods and data collection procedures for these emissions are currently being harmonized across the organization. Gränges aims to start reporting these emissions next year.
Regulations: Gränges observes all applicable local and international laws and regulations for environmental impact. Emission limits in Europe are based on requirements from the Industry Emissions Directive (IED). In Asia, limits are linked to Regulations of Shanghai Municipality on the Prevention and Control of Atmospheric Pollution, and in the US the National Ambient Air Quality Standards (NA AQS) provides the relevant legal framework. Local authorities continually monitor compliance to ensure that emissions are within limits. Emissions regulated by legislation include nitrogen oxides, sulphur dioxide, dust, volatile organic compounds (VOC) and, in some regions, oil emissions.
Governance and policies: The topic is managed by SVP Process Engineering & Operational Development (direct emissions), SVP Technology & Business Development (energy and other indirect emissions), and the regional operational and purchasing representatives. The governing policy is Gränges’ EHS Policy, which is reviewed annually and applies to all employees working at Gränges. The production sites of Gränges Asia and Gränges Europe are certified in accordance with the environmental management standard ISO 14001, while Gränges Americas has initiated a pre-study to implement an environmental management system. Emissions are monitored and managed as part of daily operations. Compliance is a prerequisite for Gränges’ continued license to operate.
