Rio Tinto plc

Rio Tinto targets a 50% reduction in Scope 1+2 emissions by 2030 and net-zero by 2050 from its 2018 baseline, aligned with a 1.5°C pathway, against an industry backdrop of dominant Scope 3 emissions (576.6 MtCO2eq) and tightening carbon pricing. Renewables deployment in aluminium smelters, nature-based carbon insetting with Indigenous partners, steel value-chain pilots via BlueScope and NeoSmelt, and fleet electrification with CATL and Volvo will deliver 4.5 MtCO2e annual reductions from solar/wind plus 1.2 MtCO2e from insetting, building on the 4.9 MtCO2e already achieved and the $200–350M committed through 2027. These initiatives, backed by $2B decarbonization capex, $1.5B renewable investments yielding $450M returns, and $200M insetting projects generating $80M over five years, convert sustainability from a cost center into a revenue stream while unlocking $150M annual efficiency savings and $1B green financing. The approach strengthens MSCI “A” ratings, mitigates regulatory and reputational risks, and positions Rio Tinto competitively in low-carbon metals markets.
