Deloitte’s commitment to environmental sustainability

At Deloitte, our purpose is to make an impact that matters with our clients, our communities and our people. We aim to accelerate our impact towards a more equitable and sustainable world by providing solutions that help create a better future for all.

We accept our shared responsibility as kaitiaki, or guardians, of our natural environment. We practice arataki, committed to creating opportunity and leading the way to a more sustainable world.

Mitigating and adapting to the impacts of climate change are monumental tasks. Progress is possible and we must take urgent action, acting collectively and individually to make changes to help reduce our greenhouse gas emissions. Deloitte is helping to lead the way toward a low-carbon future by guiding our clients on their sustainability journeys, advancing meaningful actions and change within our own operations and supply chain, and engaging our ecosystems on systems-level improvements.

Reducing Deloitte’s own emissions

Deloitte demonstrates its commitment to climate action through our WorldClimate ambition and net-zero by 2040 target. In 2020 Deloitte set near-term science-based targets and in 2024 we added long-term targets. Deloitte’s net-zero by 2040 target is inclusive of our near- and long-term targets and has been validated by the Science Based Targets initiative (SBTi). Our net-zero by 2040 target is consistent with the Paris Agreement goal to limit global warming to 1.5°C.

Our sustainability transformation

Each industry will require business transformation to reach net-zero, including the professional services industry. Deloitte is implementing policies and transformation programmes to reduce our emissions by 90% by 2040. This means reducing the emissions arising from how we work, the technology we use to do our work, the offices in which we work, and more.

Deloitte is also committed to supporting its people and the broader community to take collective and individual action and to make responsible climate choices. While the journey will be complex and unpredictable, we are committed to embracing these challenges head on and working collectively toward a sustainable future within our organisation and with our clients and suppliers.

Our climate commitments and recognition

Deloitte New Zealand is a proud member of the Sustainable Business Council (SBC) and its CEO-led Climate Leaders Coalition, supporting shared progress on emissions reduction. Globally, Deloitte continues to advance our commitments to the three core initiatives of the Climate Group, which support the advancement of renewable electricity (RE100), electric vehicle (EV) adoption (EV100), and energy efficiency/productivity (EP100). Deloitte has received an A‑ score from CDP for the fourth consecutive year, demonstrating our continued leadership on the sustainability agenda, and an A score in 2025 for the CDP Supplier Engagement Assessment, which highlights our leadership and transparency in promoting climate action throughout our supply chain. In September 2024, Deloitte’s net-zero target received third-party validation from the Science Based Targets initiative (SBTi).

Guiding clients on the path to net-zero and beyond

We recognise that business leadership and collective action is critical to addressing the climate crisis. Deloitte is uniquely positioned to help organisations as they redefine their strategies, embed sustainability into their operations, consider tax implications, navigate disclosure and regulatory requirements, and help accelerate their transformation to drive long-term value creation.
