African leaders are threatening to boycott the global warming summit in Copenhagen this December if negotiations come up short. Of course it’s not yet clear whether they have the collective will to do so, at least as a unified block, but the message came through in no uncertain terms.

Speaking at a meeting of the Africa Partnership Forum in Addis Ababa, Ethiopian Prime Minister Meles Zenawi declared that African leaders are prepared to "walk out of any negotiations that threaten to be another rape of our continent.”

Though least responsible and most at risk due, Meles said, Africans have largely been locked out of the already small transfer of wealth created to help poor nations cope and develop along a cleaner path. “But we have no intention to a free ride,” he added, suggesting that Africa is prepared to protect and expand forests and remains a “green field” for clean energy investments.

African has been trying to formulate a unified position since making a decision to negotiate as a block earlier this year. Environment ministers were able to collectively call on industrialized nations to reduce emissions by a whopping 25-40 percent by 2020 earlier this summer, but many details were left unresolved. This week’s meeting represented the latest attempt to consolidate positions.

Press reports indicate that they made some progress, although verifying details proved difficult. More than one story (see here and here) suggested that Africans planned to call on developing nations to provide some $200 billion, presumably annually, to developing countries by 2020, although it was not clear what that money would cover.

Lim Li Lin, who works on developing country issues for the Third World Network, says Africa has always more or less negotiated as a group. The question moving forward, she says, is whether leaders will be able to settle on a concrete position and then stick to it in the negotiations. “What is clear is that all this has not impacted the negotiations yet,” she says.
