Talking points

World leaders begin four days of key talks in Bonn today as the UN Framework Convention on Climate Change (UNFCCC) discusses drafting a text for a potential new agreement on the climate, to take effect from 2020. The new treaty or legally binding pact, championed by UNFCCC executive secretary Christiana Figueres, would be the first to bind both developed and developing countries to a long-term, low-carbon future. But there is still little agreement on how the accord should take shape, and countries must come up with plans for drastic emissions cuts before a crunch meeting in Paris late next year.
