To combat climate change, as well as to promote communication with local residents, Sony Group sites around the world are engaged in a variety of tree planting initiatives. Sony also promotes the conservation of indigenous species and the removal of invasive species.

Since 2009, Sony Chemical & Information Device Corporation's Kanuma site has been working with Ashio Green Growing Association (AGGC), which is putting efforts into planting trees on barren lands in the nearby mountains that are thought to have been devastated by smoke and other pollutants emitted from the smelting furnaces of the former Ashio Copper Mine. In 2009, employees and their families took part in spring planting, grass clearing, caring for saplings and other activities. In 2010, 300 trees were planted and in 2011, already 500 trees have been planted. The site also provides onsite education for employees focusing on local environmental issues with the aim of increasing employees' environmental awareness.

Sony Chemical & Information Device Corporation has also signed a three-way "Agreement relating to Forest Development" with Tochigi Prefecture and the city of Yaita, under which the company has accepted the loan of prefectural forest in Yaita. Over a period of five years, the company will conduct tree-planting activities on the land, which has been named "Creation Forest." The land is within the boundaries of Nikko National Park and is blessed with abundant greenery and seasonal beauty. Approximately 1,500 tree seedlings comprising 15 species have been planted in accordance with the altitude and ecosystem, including indigenous Tochigi Konara oak, Japanese maple, water oak and wild cherry blossom.

Sony is also involved in local tree-planting activities at other sites, including Sony Semiconductor Kyushu Corporation's Kumamoto TEC and Kagoshima TEC and Sony Chemical & Information Device Corporation's Tome site.

The facilities at Firefly Satoyama Park in Kosai City, Shizuoka Prefecture, have deteriorated in recent years, owing to a lack of management and the impact of illegal garbage dumping, which has resulted in fireflies no longer being seen in the park. In response, since summer 2009 volunteers from Sony EMCS Corporation Tokai TEC Kosai site have been working with a local volunteer group to remove garbage from the neglected park and cut weeds from around the ponds. Kosai site employees also took over the care of firefly larvae that were hatched locally and continued rearing the larvae in a water tank on the Kosai site. In March 2010, the volunteers released the larvae into a stream on the park. In June, observers were once again able to confirm the presence of fireflies in the park when the adult fireflies emitted light while they swarmed. The Sony Group employees plan to continue their conservation activities.

Sony Technology Thailand Co., Ltd.'s Chonburi Technology Center embarked on an initiative called "1,000 Seedlings for Mangrove Forest" in which employees and their families planted 1,000 mangrove seedlings at the Bangpu Nature Education Center. Sony Thai Co., Ltd. planted another 400 mangrove seedlings at Khlong Khon mangrove forest located at Samut Songkham Province, central of Thailand.

In 2003, Sony (China) Ltd. launched a tree planting program with the aim of planting 5,000 new trees over a 10-year period. To date, the company has planted about 3,600 oak and pine trees on the outskirts of Beijing, in Yanqing and Huairou, as a result of which the company's own Sony Forest is gradually becoming lush and green.

These measures are helping to prevent dust storms. Shanghai Suoguang Electronics Co., Ltd., Sony Precision Devices (Huizhou) Co. Ltd., Sony Electronics Huanan Co., Ltd. and other Group companies are also engaged in local afforestation activities.

In Huizhou, the location of Sony Precision Devices (Huizhou) Co. Ltd., an invasive and extremely prolific species of water hyacinth has covered the surface of the Dongjiang River in recent years, seriously threatening the river's ecosystem. In response, the site organized an event called "Conserving the Dongjiang River and Maintaining the Ecosystem." After implementing in-house employee training on biodiversity, the company released indigenous fish species into the river and carried out activities to remove the invasive water hyacinth. The company plans to continue pursuing these programs.

In October 2009, Sony Poland Sp. z.o.o. planted 5,600 lime, pine and other trees near Warsaw in cooperation with Poland's Department of Forestry. To support the growth of the planted forest areas, the company has continued to provide aid to help cover costs.

Sony Pictures Entertainment Inc., which is based in the United States, plants trees in locations where it films, with the number of trees planted equivalent to the number of days spent filming. As part of this initiative, the company has planted trees in places as varied as State of Tennessee, Los Angeles, California, and Bali, Indonesia.
