The Climate Pledge is a commitment co-founded by Amazon and Global Optimism in which signatories plan to reach net-zero carbon emissions by 2040, 10 years ahead of the goal set out in the United Nations' Paris Climate Agreement.

Johnson Controls is one of 53 organisations that have now signed the Pledge, and the move comes hot on the heels of the company's announcement of new environmental, social and governance (ESG) commitments, science-based targets, and its own net-zero carbon pledge. The pact will see Johnson Controls partner with other industry leaders to uncover new pathways to meet common environmental and sustainability goals.

'Sustainability is at the heart of our business and fundamental to everything we do as a company,' said George Oliver, Johnson Controls chairman and chief executive. 'Climate change is one of the greatest challenges facing the planet today. Our recent announcement to achieve net-zero carbon emissions by 2040 through innovations and technologies such as our OpenBlue platform, further demonstrates our commitment to protect and preserve the environment. We are looking forward to further enhancing the role we can play by working with Amazon, Global Optimism, and other signatories to reach net-zero carbon a decade before the important Paris Agreement's goal.'
