Deloitte’s commitment to environmental sustainability

Mitigating and adapting to the impacts of climate change are monumental tasks. The climate crisis is a risk to society at large, to our organisation and to our clients across the private and public sectors. 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 collaborating with nonprofits and civil society.

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.

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.  ​

Deloitte has set a worldwide target to reach net-zero greenhouse gas emissions (GHGs) by 2040. In 2020 Deloitte set near-term science-based targets and in 2024 we added long-term targets. Deloitte’s net-zero 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. Deloitte has committed to a 90% reduction in GHGs by 2040 from a 2019 base year across our business operations and value chain, and we will remove the remaining 10% of our emissions through the purchase of permanent carbon removals.

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 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’s supply chain is the largest source of our emissions. Through targeted supplier engagement efforts, we continue to influence our suppliers to set SBTs, we collaborate with them on emissions reduction, and we work together to advance product-level emissions reporting. Our dedicated sustainability team within procurement directly supports our efforts to reach our near- and long-term targets across the supply chain lifecycle, from supplier selection to contracting and engagement.

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.
