The HSBC Climate Partnership links the Climate Group, the Earthwatch Institute, the Smithsonian Tropical Research Institute and the WWF for the next five years, in an attempt to challenge global warming.
The money will fund the coalition's work to protect rivers and forests, and fund research into environmental issues in India and China.
The funding will also be used to identify the best course of action for five of the world's most polluted cities -- London, New York, Hong Kong, Mumbai and Shanghai.
HSBC had been involved with a similar environmental cause until last year, donating $50m to help save 12,000 plant species.
Stephen Green, HSBC chairman, said: "By working with four of the world's most respected environmental organisations, we believe we can tackle the causes and impacts of climate change.
"Over the next five years, HSBC will make responding to climate change central to our business operations and at the heart of the way we work with our clients."
