Our Carbon Trust achievements
PwC UK has been working with the Carbon Trust since 2009, achieving certification for our carbon, water and waste practices, as well as for our supply chain work. In 2025 we achieved the 'Leading' tier of their Route to Net Zero Standard.
Background
At PwC our purpose is to build trust in society and solve important problems and we are committed to drive a strong culture of quality and excellence that is core to our purpose.
We have a strong legacy of climate action, and use external benchmarking against established external bodies’ standards to help track our progress and to challenge ourselves to find innovative solutions and make continuous improvements.
Leading the transition
We’re proud to be the first organisation globally to have achieved the ‘Leading’ certification of the Carbon Trust Route to Net Zero Standard. With a rigorously assessed and verified score of 91% it signals our deep-rooted commitment to best-in-class carbon management practices.
It evidences how we’ve embedded these practices within our operations, invested to cut emissions, and built digital capability to measure, verify and communicate progress.
The certification uniquely recognises an organisation’s full journey to net zero across three tiers: ‘Taking Action’, ‘Advancing’ and ‘Leading’.
The ‘Leading’ tier specifically confirms that we have:
- set a science-based reduction target
- achieved 1.5°C aligned reductions in emissions
- implemented leading CO2e management practices
