The Governor of the province of Riau on the island of Sumatra in Indonesia has pledged to halt deforestation, which could help protect Riau's vast peatlands and forests that store 14.6 billion tonnes of carbon. Just to give you an estimate of what that figure means, it's the equivalent of an entire year's greenhouse gas emissions for the entire planet. Moreover, aside from being an important carbon store, this area is also important for biodiversity and critical for the people that depend upon these forests for their survival.

Today, we're launching the next stage in our campaign to protect the rainforests of Indonesia from the expansion of the palm oil industry. Our volunteers, dressed as orang-utans, are currently climbing over the London headquarters of the company behind Dove, which uses palm oil as one of its ingredients. Our latest research shows that Unilever, the makers of Dove, is buying palm oil from companies that are destroying valuable rainforest and peatland areas, which is bad news not only for the millions of people who depend on them for their way of life and endangered species such as the orang-utan, but also for the global climate.

Last week, Sainsbury's announced that it aims to use only sustainable palm oil in its own-brand products. Sounds great, and with Asda having made a similar announcement earlier this year, you might think supermarkets will soon be stocking only those palm oil products that weren't helping to cause the indiscriminate destruction of forests in places like Indonesia. The truth is that, while both companies score top marks for excellent intentions, delivery is going to be decidedly tricky as there is currently no credible way of telling whether palm oil is 'sustainable' or not.

If, as you read this, you're tucking into a KitKat or dipping into a tube of Pringles, you might be interested to know that they feature in our new report about the impact of the palm oil industry on tropical rainforests and climate change. Along with Flora margarine, these products contain palm oil which is linked to the destruction of forests and peatlands in Indonesia. As the report shows, it's a recipe for disaster.
