The tropical rain forests of Sumatra Island in Indonesia are recognized as a Natural World Heritage Site by UNESCO. However, deforestation over the past 30 years has led to a dramatic decline in forested area. Sony supports a project for forest conservation in Sumatra run by the World Wide Fund For Nature (WWF) Japan. Part of the revenue from sales of e-books at ReaderTM Store-Sony's e-book store-is donated to the WWF Japan conservation project, and customers can also participate in the project by donating Sony Points.

For the next generation and to help realize a sustainable society, Sony supports the efforts of the Solar Bear Fund, a Japanese NGO involved in the promotion of renewable energy sources as a means to address global warming.

In an initiative aimed at mitigating greenhouse gas emissions, Sony Bank Inc. donates to the Japanese government greenhouse gas emissions rights it has purchased on behalf of customers whose holdings in funds that make up its carbon-offset investment trust exceed a specified amount. This system enables customers to participate in an environmental preservation activity while Sony Bank manages their investments. The initiative covers three eco-funds, which have donated greenhouse gas emissions rights totaling 1,000 tons in fiscal year 2008, 2,200 tons in fiscal year 2009, 1,000 tons in fiscal year 2010 and 1,000 tons in fiscal year 2011.
