PepsiCo’s New Palm Oil Commitment: Transparency, Trust, and the Company You Keep

Since starting our work on palm oil, UCS has taken a position that a company’s zero deforestation commitment needs to cover all of its operations, not just the products it sells or manufactures in the US. US consumers holding a company accountable for its global operations is not a new concept. The successful boycott of Nestlé in the US and Europe, which started in the late 1970’s, was the result of practices by that company in the developing world.

Fall of the Oil Curtain: Palm Oil Manifesto Group Announce Forest Clearing Moratorium

The late summer and fall of 1989 marked the beginning of the end for the Soviet Union and communism in Europe. Mass movements of citizens in Poland, Hungary, Romania, and East Germany forced those governments to loosen their grip and open the gates (literally at times) to democracy. A quarter century later, we are seeing a similar toppling of the forces which aim to keep the palm oil industry trapped behind an oil curtain of corporate secrecy and rampant destruction of our forests, peatlands, and atmosphere.

Out with Duh-nuts, in with DO-nuts: Two Major Fast Food Brands Tackle Deforestation

Every Tuesday night in college, I would get in my get in my ’87 Tercel and drive 15 miles over winding surface streets and three highways to my destination. Lit up like a Christmas tree, green, red, and white, it was a beacon in a darkened and deserted mall parking lot: Krispy Kreme. Read more >
