Carbon Footprint — Supply Chain: How does Nationwide Building Society score?

Nationwide quantifies Scope 3 upstream emissions (~19,500 tCO2e across categories 1, 2 and 4) using CDP Supplier Engagement Programme data covering ~71% of spend. Scope 3 downstream (financed emissions) from the mortgage portfolio are calculated using PCAF methodology at ~3.2M tCO2e. Business lending emissions are now disclosed following the Virgin Money acquisition. Methodology is documented in the Basis of Reporting 2025. Not all Scope 3 categories are quantified.

Emissions Trajectory: How does Nationwide Building Society score?

Scope 1 emissions have reduced 45% compared to the 2021/22 baseline, driven by gas removal from 95% of Nationwide branches by end 2024. This is a verified absolute reduction. However, Nationwide acknowledges its Scope 3 downstream mortgage target (44% reduction by 2030) is 'not achievable' without government policy changes, and the trajectory for financed emissions remains uncertain. Total emissions including financed activities (~3.2M tCO2e) are largely outside Nationwide's direct control and n

Energy Source: How does Nationwide Building Society score?

Nationwide sources 100% renewable electricity for operations, with approximately half from a solar power purchase agreement (PPA) and the remainder from a green tariff backed by REGOs (wind, solar, hydropower). This is documented in the Climate-related Financial Disclosures 2025 Basis of Reporting. The PPA provides additionality. Solar panels are installed at the Swindon head office. The society is actively removing gas from all operations by 2030, with 95% of branches already gas-free.

Resource Use & Waste: How does Nationwide Building Society score?

Nationwide states zero waste to landfill since 2015, using a waste hierarchy approach prioritising reduction, reuse, then recycling, with a target to divert 99% of waste from landfill. Payment cards are made from recycled plastic (saving ~35 tonnes carbon annually). Solar panels installed at HQ. However, no publicly quantified circularity targets or comprehensive material footprint assessment was found. As a financial services company, the material footprint is inherently limited.

Water Impact: How does Nationwide Building Society score?

No specific water consumption data, water footprint reporting, or water reduction targets were found in publicly available Nationwide disclosures. As a financial services company operating offices and branches, Nationwide's direct water impact is inherently low — no manufacturing, no chemical discharge, no water-intensive processes. The Oakfield development includes 'swales' that collect and release water for habitat purposes, and the Newbury Data Centre has wetland areas. However, without quant

Targets & Commitments: How does Nationwide Building Society score?

Nationwide set intermediate (by 2030) science-based targets in December 2022 using SBTi methodologies: 42% absolute Scope 1 reduction, continuation of 100% renewable electricity, 42% Scope 3 upstream reduction, and 44% Scope 3 downstream mortgage reduction. A published Transition Plan (2023) details actions. However, Nationwide does not appear on the SBTi Target Dashboard as 'committed' or 'targets set', meaning targets are self-calculated using SBTi methodology but not formally validated. Addit
