LEGO sustainability score: 42/100

LEGO reports full Scope 1 (~23,403 tCO₂e in 2023) and Scope 2 (effectively 1 tCO₂e) under GHG Protocol with ISAE 3410 third-party verification. Scope 1 and 2 account for only ~1% of total emissions due to 100% renewable electricity matching. Multi-year tracking published annually with granular breakdowns.

LEGO quantifies full Scope 3 emissions (~1.80M tCO₂e in 2023, ~99% of total) using GHG Protocol with third-party verification. Active Supplier Sustainability Programme engages 158+ suppliers with intensity-based reduction targets for 52 highest-impact suppliers covering ~50% of Scope 3. However, Scope 3 has risen significantly since 2019 (1.02M to 1.80M tCO₂e).

Total absolute emissions rose from 1.16M tCO₂e in 2019 to 1.82M in 2023, and ~2.19M in 2025—a 90% increase over six years. FY2024 showed a dip to ~1.7M, but the overall trend is sharply upward driven by production growth. Employee bonus KPIs use intensity-based (per brick) metrics, not absolute reductions, contradicting SBTi-validated absolute targets.

LEGO has matched 100% of operational electricity with renewable energy since 2017 via RE100 membership, on-site solar, and offshore wind investments (DKK 6B+). New factories in Vietnam and Virginia designed for 100% renewable energy with on-site solar and PPAs. Scope 1 gas heating transitioning to district heating and geothermal. Some reliance on unbundled RECs limits a higher score.

LEGO invests in nature-based carbon removal including reforestation (~400,000 hectares in Lower Mississippi Valley) with biodiversity co-benefits. Partnerships with Climate Impact Partners for biochar and enhanced rock weathering. However, core business uses ~100,000 tonnes petrochemical-derived plastic annually with significant upstream extraction impact. No formal TNFD disclosure or quantified nature footprint found.

LEGO achieves <1% waste to landfill for fourth consecutive year, recycles 90%+ of all waste including 100% of plastic molding waste. 47% of plastic resin mass-balance certified by 2024 (33% renewable sources). LEGO Replay reuse program handles <0.5% of annual production. Fundamental business model remains linear: ~100,000 tonnes new plastic produced annually.

LEGO quantifies water consumption and reduced global factory water use for three consecutive years to 753,711 m³ in 2024 (down 56,000 m³ from 2023). Water treatment facility in Monterrey, Mexico saves 85,055 m³ freshwater; shallow groundwater capture in Billund; air-cooling in Vietnam factory. No significant water pollution incidents found.

LEGO holds SBTi-validated near-term targets (37% absolute reduction by 2032 vs 2019 baseline, 1.5°C aligned) and net-zero targets (90% reduction by 2050). Carbon removal investments (~DKK 54M) positioned as complementary, not substitutes. Shadow carbon pricing used for decisions. However, emissions have risen 56% against the 37% reduction target, creating serious deliverability questions.

LEGO publishes annual Sustainability Statement with externally verified GHG emissions under ISAE 3410. Chief Sustainability Officer (Annette Stube) leads sustainability. Carbon KPI linked to salaried employee bonuses since 2024. Shadow carbon pricing applied to investments. TCFD/CSRD preparation underway. CDP score dropped to C in 2022; private ownership limits shareholder transparency mechanisms.

LEGO is member of National Association of Manufacturers (NAM), identified by InfluenceMap as engaging on climate policy with predominantly negative positions; no formal review of association climate engagement published. Abandoned 'Bottles to Bricks' recycled PET initiative in 2023 drew credible criticism. Total emissions rose 56% since 2019 SBTi baseline despite 37% reduction target, creating credibility gap.
