4 Introduction
Strong increase in sustainability, environment and climate awareness
Action and improvement needed on waste, recycling and emissions (CO2) to defend aluminium’s position
5 Sustainability challenges and opportunities in the aluminium value chain
6 Hydro’s 2030 sustainability targets
Social responsibility Environment Climate • 1:1 rehabilitation Strengthening local • Tailings dry backfill Cut CO2 emissions communities and our • Utilize 10% of bauxite residue by 30% business partners • 50% reduction in key non-GHG air emissions
Sustainability in the marketplace: our greener products portfolio

Optimizing production by combining: • Physics-based models • Sensor data • Advanced analytics algorithms A new approach to the chloride process
Al2O3 3CO Aluminium chloride production CO2 to CO conversion e.g with hydrogen: 3CO2 + 3H2 = 3CO + 3H2O or electrolysis: 3CO2 = 3CO + 1.5O2 3Cl2 3CO2 2AlCl3

17 Carbon capture from electrolysis
A medium to longer term solution towards zero-CO2 Hall-Héroult electrolysis • Direct Air Capture (potentially utilizing waste heat from electrolysis or off-site) • Off Gas Capture utilizing waste heat from electrolysis
18 Recycling - a part of the solution
Aluminium’s recyclability is a fantastic competitive advantage 5% 75% 100% to recycle still in use equal quality Challenge: Our approach:
19 Encouraging recycling project portfolio
Remelt & recycling LIBS pilot Thin-gauge scrap Battery recycling Packaging ambition
• Double EBITDA Pilot for faster Screw-extruder Possible future Recycling-friendly aluminium food • Use additional 500 learning of under development source of scrap packaging kt post-consumer industrial alloy for compacting thin and profit scrap per year sorting and difficult scrap
20 Our premium low-carbon products
REDUXA CIRCAL Certified, low-carbon aluminium with a maximum Range of prime quality aluminium made with a carbon footprint of 4.0 kg CO2 per kg aluminium minimum of 75% recycled, post-consumer scrap

22 Summing up Increased sustainability awereness is about to change our industry Sales
Directional 2050 Outlook
• IAI: around 165 Mtpy Al demand - 65 Mtpy recycled (40%) - 100 Mtpy primary • A net-zero industry • Clean energy sources • New-builds with zero-emission technology • Al-industry will receive few offsets and struggle competing for bio resources
Zero-emission technology Recycling (Hydrogen/electric) • Existing and modern HH-smelters with Hall-Heroult + DAC CCS/offsets/bio on-site CCUS or off-site DAC
