All of us are interconnected by Te Taiao, our natural environment, and have a responsibility to not only preserve it, but to leave it better for future generations.

At Callaghan Innovation, we’re working with innovators, investors, corporates, government and others to develop a globally competitive CleanTech ecosystem in New Zealand. The aim is to grow businesses that develop innovative offerings, provide meaningful jobs and help solve climate change, water quality and resource-use problems for New Zealand and, importantly, the world.

Check out some of the exciting initiatives in the CleanTech space.

What is CleanTech?

CleanTech: High-tech businesses creating products to help solve climate change and other environmental problems.

ClimateTech: High-tech businesses creating products to reduce greenhouse gas emissions in areas such as alternative foods, alternative fuels and energy storage. 

Environmental innovation: A whole-of-system view of innovation bringing together factors such as policy, infrastructure and technology to deliver transformative positive impacts for the environment.

CleanTech is critical for a zero-carbon, climate-resilient future. New technology will play an important role in solving climate change and other environmental problems, while creating a high-value export industry and new employment opportunities.
