G8 agrees to climate targets despite differences with developing nations

The Group of Eight industrialised economies, including America, today agreed for the first time that they must limit worldwide temperature rises to no more than 2C, but failed to reach agreement with developing nations on how that should be achieved – a disappointment to those expecting Barack Obama to break a decade long deadlock.

The G8, representing the richest nations, also agreed for the first time that it should collectively cut emissions by 80% by 2050, and that the world should be able to cut its emissions by 50% by the same date.

In a fudge designed to recognise the difficulties different rich countries will face in meeting this target, the agreed G8 communique released at the L’Aquila summit set a fuzzy baseline for their 80% cut "of 1990 or more later years". The communique also acknowledges baselines may vary but "efforts must be comparable".

UN scientists have used 1990 as the starting point, but the US and Japan have been using 2005 levels. A cap on global warming of 2C is seen as the minimum to prevent irreversible global warming.

There had been hopes in the run up to the summit that the developing countries and the G8 would strike an agreement that world wide emissions should be cut by 50% by 2050, but developing nations held out. These countries, led by China, India and Brazil, said they wanted to see more specific targets from the rich nations before they would make any commitments. In addition, they wanted the rich countries to put out a specific figure on how much cash they were willing to pay to help with green technology transfers.

Obama has so far resisted interim 2020 targets as he faces the more immediate task of passing cap and trade legislation through Congress quickly. Nevertheless, Gordon Brown last night hailed the deal as "historic agreements in terms of desired outcomes in climate change".

Obama will still chair a meeting of 17 nations, at which he will try to get a collective agreement to limit temperature rises to no more than 2C on pre-industrial levels. Brown insisted such an outcome would represent "real progress".

Green groups such as WWF and Oxfam argued the 2C aspiration was severely weakened by the lack of interim targets on how it should be achieved. Kim Cartensen, the WWF Global Climate Initiative leader, said: "If they don’t outline a path to reach an announced goal, the two degree statement will just join a long list of broken promises. An ambitious mid-term target for 2020 of developed countries is needed to ensure immediate action."

British officials argue there is still time to hammer out a deal before the UN-sponsored Copenhagen summit called to set a world wide framework to cut carbon emissions after 2012. Brown insisted: "Today we have laid the foundations for a Copenhagen deal that is ambitious, fair and effective. The world has now agreed that the scientific evidence is compelling and the G8 countries have agreed that developed countries will reduce carbon emissions by 80% by 2050."

But the clock is now ticking fast as the developed countries have yet to agree their respective responsibilities.

Two degrees

Filed under:

The countries of the G8 today approved a target of 2° C rise in global average temperature above the natural, preanthropogenic climate, that they resolve should be avoided. The Europeans have been pushing for 2 degrees as a target maximum temperature for several years, but this is something of a development for the Americans. We posted recently on two new papers about what it would take to limit global average warming, finding that it would require fairly strong change in trajectory. About 2° C as a target, we wrote,

… even a “moderate” warming of 2°C stands a strong chance of provoking drought and storm responses that could challenge civilized society, leading potentially to the conflict and suffering that go with failed states and mass migrations. Global warming of 2°C would leave the Earth warmer than it has been in millions of years, a disruption of climate conditions that have been stable for longer than the history of human agriculture. Given the drought that already afflicts Australia, the crumbling of the sea ice in the Arctic, and the increasing storm damage after only 0.8°C of warming so far, a target of 2°C seems almost cavalier.

Nevertheless, we view today’s development as a constructive step.
