‘Countries join forces to save life on Earth”, the front page of the Independent told us. “Historic”, “a landmark”, a “much-needed morale booster”, the other papers chorused. The declaration agreed last week at the summit in Japan to protect the world’s wild species and places was proclaimed by almost everyone a great success. There is one problem: none of the journalists who made these claims has seen it.

I checked with as many of them as I could reach by phone: all they had read was a press release which, though three pages long, is almost content-free. The reporters can’t be blamed for this – it was approved on Friday but the declaration has still not been published. I’ve pursued people on three continents to try to obtain it, without success. Having secured the headlines it wanted, the entire senior staff of the convention on biological diversity has gone to ground, and my calls and emails remain unanswered. The British government, which lavishly praised the declaration, tells me it has no printed copies. I’ve never seen this situation before. Every other international agreement I’ve followed was published as soon as it was approved.

The evidence suggests that we’ve been conned. The draft agreement, published a month ago, contained no binding obligations. Nothing I’ve heard from Japan suggests that this has changed. The draft saw the targets for 2020 that governments were asked to adopt as nothing more than “aspirations for achievement at the global level” and a “flexible framework”, within which countries can do as they wish. No government, if the draft has been approved, is obliged to change its policies.

In 2002 the signatories to the convention agreed something similar, a splendid-sounding declaration that imposed no legal commitments. They announced they would “achieve by 2010 a significant reduction of the current rate of biodiversity loss”. Mission accomplished, the press proclaimed, and everyone went home to congratulate themselves. Earlier this year the UN admitted the 2002 agreement was fruitless: “The pressures on biodiversity remain constant or increase in intensity.”
