The HSBC Climate Partnership thus sponsored the design and trial of a cost-effective unit to capture pig slurry and turn it into methane gas that provides villages in Hubei Province with free gas for cooking and heating.

This simple but effective solution prevents pig slurry from polluting the water course. It also provides 'clean' energy and reduces spending on electricity generated by burning fossil fuel.

The project – a joint effort between the Chinese government, HSBC Climate Partnership and WWF – showed how demonstration projects can be turned into scalable solutions and long-term policy.


A new regulation in Hubei Province in central China will require all new pig farms to introduce this simple technology.

As a direct result of this and other work on the Yangtze by WWF and the HSBC Climate Partnership, the Chinese Ministry of Water has asked WWF for advice on incorporating international best practices into China's next 25-year master plan for sustainable water management. This plan will require the managers of China's seven biggest rivers to ensure proper functioning of the waterways and wetlands, benefiting hundreds of millions of people, as well and animal and plant species.

Now I don't have to pay for coal or wood. And then when I want to start cooking I just light the flame. There's no soot or ash to deal with either. This gas saves me precious money and time, so I can do other things

About the HSBC Climate Partnership

The HSBC Climate Partnership, a five-year environmental programme between HSBC, The Climate Group, Earthwatch Institute, the Smithsonian Tropical Research Institute and WWF, ran until December 2011. It helped accelerate the adoption of low-carbon policies and reduce the impact of climate change on people, forests, freshwater and cities.
