The 5 key issues that stand in front of a global climate deal

World governments are hoping that this year will mark a breakthrough in the slow-paced United Nations climate talks



GENEVA—After failing six years ago to craft a global agreement to fight climate change, world governments are hoping that this year will mark a breakthrough in the slow-paced United Nations (UN) climate talks.

In Geneva this week, negotiators from more than 190 countries are working on an early draft of a deal that’s supposed to be adopted in Paris in December.

At this point it’s essentially a wish list with multiple options reflecting the diverging preferences of rich countries like the United States and Japan, major developing economies such as China and India, oil producers in the Middle East, and Pacific islands at risk of being submerged by rising seas.

Over the next 10 months, governments must try to find common ground on a range of thorny issues.

Here’s a look at the most important ones:

Who does what?

Unless the world can agree on a formula for how to divide the cuts in heat-trapping carbon emissions that scientists say is required to avoid dangerous levels of warming, Paris will be deemed another failure, just like an acrimonious climate summit in Copenhagen in 2009.

Under the previous UN climate deal, the 1997 Kyoto Protocol, only rich countries were required to limit their emissions, primarily from burning coal, oil and gas.

Now, with the majority of emissions coming from developing countries, everyone is supposed to chip in.

But how?

Continuing the split between developed and developing countries is a no-go for the former, while the latter are concerned that a new system would enable rich countries to hand over the responsibility for tackling global warming.

Binding or not?

If and when delegates emerge with a deal in Paris, what are they going to call it: A “protocol,” “legal instrument” or “agreed outcome with legal force?”

All those options remain on the table more than four years after they were introduced.

Those who, like the European Union (EU), expect a legally binding protocol with emissions targets for all are likely be disappointed.

The U.S. doesn’t want that, knowing it most likely couldn’t get approval by Congress.

Finding a legal form acceptable to everyone is a major challenge.

One possibility is requiring each country to set a target, but without a penalty for missing it.

Who’s got the money?

Some critics of the UN talks describe them as a massive wealth transfer scheme.

That ignores the fact that most developing countries need money and technology to grow their economies in a cleaner way than today’s rich countries did for decades before the impact of carbon pollution was understood.

Also, the world’s poor are the most vulnerable to climate change and did the least to create the problem.

But it’s also wrong to assume that the good of the planet always takes centre stage in the negotiations.

Rich, poor and middle-income countries all want the deal to reflect their national economic priorities.

Right now the trickiest money issue is how to raise the US$100 billion in annual climate aid that rich countries promised to provide by 2020.

Global offsets?

Countries still haven’t decided whether the new agreement should include market mechanisms that would allow countries and companies to offset their own emissions by paying for reductions elsewhere.

Europeans and others see carbon markets as essential to fighting climate change.

But some anti-capitalist countries, led by Bolivia, are opposed to the idea for ideological reasons, warning that markets will turn nature into a commodity.

Long-term goal?

To avoid the most dangerous impacts of climate change, countries have already agreed that the global temperature rise should stay below 2°C compared to pre-industrial times.

But many want the Paris deal to state more specifically what that means in terms of emissions cuts.

Some say the agreement should incorporate the UN climate science panel’s finding that to have a two-thirds chance of staying below 2°C the world must cut emissions by 40- to 70 per cent by 2050.

Others want to go further, calling for net zero emissions by mid-century, meaning no more emissions than the world’s forests can absorb.
