西雅圖樂團珍珠果醬10日晚上在美國洛杉磯論壇球場登場，此番為期69場的巡迴演唱會4月起在倫敦開唱，並將在11月25日澳洲伯斯劃下句點。珍珠果醬樂團10日也宣佈，他們將資助9個非營利團體，協助他們減緩全球暖化的工作，以彌補此次巡迴演唱旅程中，他們搭坐卡車、巴士、飛機，以及在下榻旅館、演唱會地點以及歌迷從各地趨車前往演唱會所排放的溫室氣體二氧化碳。
珍珠果醬稱這次創舉為他們的「碳作品」（Carbon Portfolio）。該樂團10日宣布將捐贈美國太陽能協會、博那維爾環境基金會、瀑布景觀保育協會（Cascade Land Conservancy）、國際保育組織（Conservation International）、地球軍團（EarthCorps）、綠色培力（Green Empowerment）光耀地球（Honor the Earth）、島屋（IslandWood）、以及華盛頓乾淨能源倡導等組織總計10萬美元。其中，總部設在華府的國際保育組織還是參與設計珍珠果醬「碳作品」的合作夥伴。
為了抵銷與這次樂團巡迴演唱相關的碳排放，國際保育組織協同兩個厄瓜多的基金會，Jatun Sacha和El Kaimán de la Lagua de Clube，一同努力復育厄瓜多北部約30多公頃受到損害的熱帶森林。
國際保育組織投入復育工作，為厄瓜多僅存而重要海岸雨林添加另一層保護──這片雨林是數種特殊動植物的棲息地，包括美洲豹、長條傘鳥、巨食蟻獸、以及瀕臨絕種的紅面吼猴。
珍珠果醬的吉他手戈薩德（Stone Gossard）表示：「我們選擇國際保育組織作為為『作品』的合作對象，並著眼於支持能積極影響氣候、環境以及地方社群的地方、區域、國家、國際環保策略。」
戈薩德並表示：「我們相信積極主動為環境和乾淨能源等議題的倡議團體，而非等待政府為我們確認解決之道。我們參與並支持各種組織和不同策略的團體，希望藉此開創新的模式，讓類似我們這樣關心地球未來健康與其脆弱生態環境的同業人員，有前例可遵循。」
珍珠果醬同時也要求歌迷減少他們自己的碳足跡（carbon footprint，日常生活的碳使用量）來參與環保工作。歌迷可以利用由國際保育組織網站所提供的碳計算機來計算日常生活產生多少碳。一旦歌迷計算了他們的碳足跡，將得到如何抵銷這些碳排放影響的各種建議選擇。
Tonight Pearl Jam is onstage at The Forum in the midst of a 69 date world tour that opened April 20 in London, England and will close November 25 in Perth, Australia. The band announced today it will offset emissions of the greenhouse gas carbon dioxide (CO2) released on the tour - from the trucks, buses, airplane travel, hotel rooms, concerts venues and fans driving to and from their concerts - by providing funding to nine nonprofit organizations that help to reduce global warming.
Calling the initiative their "Carbon Portfolio," the band announced today that they are contributing a total of $100,000 to the American Solar Energy Society, the Bonneville Environmental Foundation, the Cascade Land Conservancy, Conservation International, EarthCorps, Green Empowerment, Honor the Earth, IslandWood and the Washington Clean Energy Initiative.
One of the band's Carbon Portfolio partners is the Washington, DC based nonprofit Conservation International.
To offset emissions associated with the band's tour, Conservation International, in collaboration with two Ecuadorian organizations, the Jatun Sacha and El Kaimán de la Lagua de Clube foundations, is working to restore up to 30 hectares (74 acres) of degraded tropical forest in northwestern Ecuador.
Conservation International's restoration efforts add another layer of protection to this critical remnant of Ecuador's coastal rainforest that is home to a number of unique plant and animal species, including the jaguar, the long wattled umbrella bird, the giant anteater and the threatened mantled Howler monkey.
"We selected Conservation International for our Portfolio with an eye towards supporting local, regional, national and international strategies that positively affect climate, environment and local communities,” said Pearl Jam guitarist Stone Gossard.
"We believe in businesses that proactively take the lead on the issues of environment and clean energy, rather than waiting for our government to identify solutions for us," Gossard said. "By identifying and supporting a diverse group of organizations and strategies, we hope to create new models for businesses like ours who are looking to invest in the future health of our planet and its delicate ecosphere."
Pearl Jam also is asking fans to get involved by helping to reduce their own carbon footprint. Fans can calculate how much carbon their daily activities generate using a carbon calculator found on Conservation International’s website at www.conservation.org. Once fans have calculated their carbon footprint they will be presented with options to offset that impact.
