The Alberta Heritage Savings Trust Fund is a sovereign wealth fund established in 1976 to save a portion of Alberta's oil and gas revenues for future generations. At its peak philosophy, the fund was meant to diversify Alberta's economy away from resource dependence and provide income when petroleum resources eventually decline. Currently valued at approximately $20 billion, the fund generates investment returns that flow into provincial general revenues. Unlike Norway's much larger petroleum fund, Alberta's Heritage Fund has seen limited growth over decades due to governments drawing on it during budget shortfalls rather than consistently contributing new resource revenues.
