Net Zero Plan
We have committed to becoming a science-based net zero organisation by 2040.
We have made significant progress in decarbonising our operations since we set our initial targets. We have exceeded our near-term science-based emissions reduction target to reduce scope 1 and 2 emissions 30% by 2025 - achieving 86% reduction in 2024. We are well on track to achieve 30% reduction in scope 3 emissions by 2025 – in 2024 we achieved a 29.5% reduction.
While this marks a significant milestone, it is a step in our longer journey toward becoming a science-based net zero organisation.

Our targets
Our near- and long-term science-based emissions reduction targets and science-based net zero target are set out below. These have been validated by the Science Based Targets initiatives (SBTi) and are in line with 1.5oC mitigation pathways – currently the most ambitious designation available through the SBTi process.

* All targets relate to a baseline year of 2019.
** Scope 3 relates to those emission categories within the SBTi target reporting boundary including purchased goods and services, capital goods, waste, business travel and employee commuting. Arup also monitors additional Scope 3 categories, but these are outside of the SBTi target reporting boundary.All targets relate to a baseline year of 2019.
Our Net Zero Plan
Our Net Zero Plan details how we will achieve these targets and become a net zero organisation by taking action across three priority areas: our offices, our travel and our supply chain.
We report our GHG emissions annually in our Financial Statements and Annual Report. Our emission results have undergone third party assurance. Read our complete ESG assurance statement here.

How we're governed
We recognise the value of transparency around organisational governance, how businesses are led and managed, and how stakeholder considerations are reflected in decision making, and our governance reflects that.
