Protecting forests can have an immediate positive impact on limiting global warming. In China, we made efforts in improving air quality through long-term maintenance of forest and ecological parks. In 2000, ConocoPhillips started to sponsor the Badaling Friendship Forest (BIFF). Since then, we provided long-term funding support to maintain the environmental park. For years, the BIFF provides not only an effective way to preserve the ecological environment of the Badaling scenic area, but also a place for visitors to relax and enjoy the splendor of the Great Wall. Currently, the forest covers 1.3 million square meters and it can absorb 47,450 tons of CO2 every year.
