Environment

Across our global network, Deloitte firms are implementing actions set out in the NZTP. Recognizing business travel is a significant emissions source, Deloitte NSE² developed the Travel Emissions Calculator to provide greater understanding of the environmental impacts of necessary travel—and how thoughtful choices can help reduce them. Across Deloitte’s global network, we have reduced scope 3 emissions from business travel per full-time equivalent (FTE) by 61% in FY2026 from FY2019 levels.

While technology is foundational to our work with Deloitte clients, it also accounts for nearly a third of Deloitte’s network-wide GHGs. This includes the use of cloud and data centers, laptops and mobile devices, and AI. To help address this, Deloitte is embedding sustainable practices for the technology we develop with our alliances, reducing emissions across the life cycle of technologies used by Deloitte people—from energy-efficient hardware procurement to running software on lower-carbon cloud and data center operations—and helping mitigate the energy demands of GenAI. For example, Deloitte South Asia developed Enterprise Conscious Code, an AI-powered suite that helps optimize enterprise code and compress media files to reduce energy use and emissions. The solution is now being piloted across Deloitte South Asia. 

Over the past decade, Deloitte has worked to reduce the environmental impact of our facilities, integrating sustainability considerations across the real estate cycle. For example, the Deloitte University EMEA campus was constructed using renewable and lowcarbon materials. 

In addition, in FY2026, 97% of the electricity Deloitte purchased network-wide was renewable—and Deloitte continues to explore ways to bring new renewable energy capacity to the grid in pursuit of our 100% renewable electricity goal. For example, Deloitte US secured a long-term contract to buy renewable electricity (or its certificates) that is expected to supply most of its renewable energy needs and reduce electricity-related emissions. 

Deloitte is also working with suppliers to set net-zero targets for themselves that are aligned with Deloitte’s own goals, collaborate on emissions reduction, and advance product-level emissions reporting. 

As we continue to increase our understanding of Deloitte’s network-wide scope 3 inventory each year, we are working closely with suppliers to improve our actionable baseline and develop potential actions to continue to reduce emissions within our value chain. Many sources of Deloitte’s supply chain emissions have high measurement uncertainty, contributing to fluctuations in reported emissions over time. As we pursue Deloitte’s network-wide emission reduction targets, we remain focused on increasing the precision with which we measure our emissions, including improving the accuracy of our emissions baseline and current year data toward the goal of improved emissions comparability over time. These efforts are supported by working with Deloitte suppliers to obtain more precise product-level data, as well as evolving our measurement methodologies to align with leading practices. 

We continue to help create solutions that can facilitate the transition to a lower-carbon economy. Given our network’s use of air travel in serving Deloitte clients, Deloitte prioritizes collaborations to help expand the market infrastructure to reduce emissions from travel and support low-emission transportation solutions. 

Deloitte’s agreements with World Energy LLC helped enable Deloitte Global and five Deloitte firms to purchase emissions reductions from Sustainable Aviation Fuel (SAF), as part of a multi-year commitment. Deloitte firms continue to make progress in scaling investment in SAF, including Deloitte US through its support of the Minnesota SAF Hub, which is now blending and uplifting SAF in-state. 

In addition, Deloitte firms work with their ecosystems to produce actionable insights like Connecting Nature, Climate, and Capital, a collaborative report by Deloitte New Zealand, Bank of New Zealand, and The Nature Conservancy. The report explores how New Zealand can develop high-integrity, nature-based carbon and biodiversity credits and access both domestic and international markets— and highlights the opportunity to unlock private investment into nature restoration and conservation, helping deliver benefits for sustainability, biodiversity, and communities. 

Along with reducing Deloitte’s emissions, Deloitte entities are investing in solutions that can deliver carbon emission reductions—and help scale early-stage technology and nature-based solutions. 

We provide pro bono support and finance (through a combination of direct funding and carbon credits) to a diverse range of external sustainability initiatives that we consider high-impact projects. Depending on Deloitte Global’s or each Deloitte firm’s specific context and objectives, the investments are funded through Deloitte’s voluntary internal carbon price and/or other financing mechanisms. For example, Deloitte DCE³ contributed to the restoration of ecosystems along the Portuguese coast through its support of SeaForester, which uses innovative techniques to regenerate seaweed forests, a very effective natural CO₂ absorber.
