US-China climate deal will take the world towards a catastrophic beyond 4C temperature increase pathway

On November 12, 2014, US president Barack Obama and Chinese president Xi Jinping announced a joint plan to reduce greenhouse gas (GHG) emissions.
The deal came as a big surprise to most. After all, it was a deal between the world’s top polluters — the US is the world’s biggest historical polluter while China is its biggest current polluter.
According to news reports, the US and China had worked on the deal quietly for the past nine months.
Commentators from across the world have hailed the deal. Terms like “historic”, “ambitious”, “breakthrough” etc have been used to describe it.
Many have commented that this agreement will lead to a global deal in Paris in 2015 where countries are to agree to a post-2020 deal to tackle climate change.
But in this cacophony of news, views and opinions, many important issues and concerns arising out of this deal have been lost.
Analysis: US-China climate pact breaks barriers to a global deal
Is this deal in line with keeping the global temperature increase below 2C that countries have pledged under the UN Framework Convention on Climate Change (UNFCCC)?
Is this deal in line with the principals of the Convention, especially equity and common but differentiated responsibilities and respective capabilities (CBDRRC)?
Can this be used as a benchmark to get an ambitious deal in Paris in 2015 and beyond? What will be implications of this deal on other emerging and developing countries?
These are the most important questions to answer before we give our verdict on the significance of this deal.
But let me start by saying that any deal that brings the world’s top two polluters on the table is good news. Now let’s understand its implications.
The agreement
Under the deal, the US will reduce emissions by 26-28% below the 2005 levels by 2025. The earlier target of the US was 17% below 2005 levels by 2020.
If we benchmark these numbers from the 1990 levels, then the US will reduce its emissions by less than 3% by 2020 and by 12-14% by 2025 compared to the 1990 levels.
China, on its part, will peak its carbon emissions by 2030 and then start reducing it.
It has also agreed to raise the share of non-fossil fuels to 20% of its primary energy mix by 2030. It has not, however, announced any specific emissions targets.
The US has vowed to help China to “slow, peak and then reverse” its emissions.
The real deal
Under this deal, the US will do much less than what it should.
By 2025, while the European Union (EU) will cut its emissions by at least 35% from the 1990 levels, the US will cut only 15%. In 2025, the per capita emissions of the US will still be around 14-15 tonne, compared to 6.5 tonne of the EU and 3.5 tonne of India.
So, the implications of this “ambitious” deal is that on a per capita basis the US will continue to emit twice the EU and more than four-times the emissions from India.
All projections show that to meet the 2C target, US emissions should be at least 50-60% below 1990 levels by 2025 considering its historical responsibility of causing climate change and its present capability of solving it.
As far as China is concerned, by 2030 its emissions would peak at around 18-20 billion tonne CO2e (carbon dioxide equivalent).
Its per capita emissions in 2030 would be around 12-14 tonne. Interestingly, the per capita emissions of the US will also be about 12-13 tonne in 2030.
In terms of cumulative emissions, by 2030 (that is, the 1850-2030 period) the share of greenhouse gas emissions of China would reach about 16% of the world’s total.
Again, interestingly, the cumulative emissions of the US too will be exactly 16 per cent of the world’s total by 2030.
So is this a coincidence that the per capita emissions and the cumulative emissions of China and US are converging in 2030? Or is this by design?
If this is by design, then it is quite a convenient deal wherein the world’s top two polluters have agreed to take whatever carbon space they need, leaving the remaining for the rest of the world.
But what is most interesting is that through this agreement, China has been able to get for itself an equitable deal.
In 2030, China will account for 16-17% of the global population and in 2030 it will also occupy 16% of the carbon space.
The question is, can other developing countries get an equitable deal too?
Energy: the implications
On November 12, the International Energy Agency (IEA) published its 2014 version of the World Energy Outlook report.
The report points out that the global energy system is on a path which will lead to 3.6C temperature rise and the world will exhaust its carbon budget by 2040.
So, does the US-China deal change this scenario? The answer is no. In fact, the US-China deal is the business-as-usual scenario that IEA has projected.
With a massive projected increase in shale gas production by 2030, the US energy system is not exactly moving away from fossil fuels; it is merely moving from coal to gas.
Similarly, China’s peaking its emissions by 2030 means that its energy system will remain fossil fuel dominated. In fact, the pledge of China to have 20% non-fossil fuels in its energy mix is disappointing.
Under the Cancun Agreement, China had already pledged to have 15% non-fossil fuel in its energy mix by 2020. So, an increase of a mere 5% from 2020 to 2030 is not exactly “ambitious.”
Developing implications
From now till 2030, the developed countries and China will appropriate a large part of the remaining carbon budget.
Annex 1 countries and China together will emit about 600 billion tonne of GHGs, which is 60% of the remaining carbon budget from now till 2050.
The remaining 40% will have to be shared between the 70% of the world’s population.
This means that not much would be left for the billions of poor who have no access to electricity or clean cooking fuel or modern means of transportation. So what should they do?
The easiest option left to them is to be like the US and China and keep emitting and take the world to a path of 4-5C temperature rise.
But in this case, it will be the poor of the poor countries that will suffer the most; the rich and the would-be rich of the developing world will find some way out like the developed countries.
But there is another option. The developing countries can come together and demand their rightful carbon space.
They can demand that the remaining carbon space must be apportioned based on historical responsibility and present capability.
They can demand that they have the right of sustainable development and the rich countries can take more carbon space only if they transfer finance and technology for low carbon growth in developing countries.
They can, therefore, reject bilateralism and push for true multilateralism.
Indian implications
Many have opined that there will be pressure on India to fall in line as the US and China have now announced their emission caps. I believe the opposite holds true.
India is, and will, remain a low emitting country at least till 2030. In 2030, its total emissions would be about 5 billion tonne – 10% of the world’s total.
This will be similar to that of the US and one-fourth of China’s.
Its per capita emissions would be 4 tonne, which will be less than a third of the US and China.
During 2011-2030, India will emit about 80 billion tonne of GHGs compared to 280 billion tonne by China and 100 billion tonne by the US.
India will, therefore, occupy only about 7% of the remaining carbon space by 2030 compared to 11% by the US and 25% by China.
If India applies the same principals as that of the US and China, then it need not do much. In fact, it can very well justify business-as-usual. So, the US-China deal reduces and not increases the pressure on India.
But I believe that it would not be in the interest of India to follow what the US and China have done.
It will not be in the interest of the poor of India to have 4-5C temperature rise; they will not be able to cope with it.
It is also not in the interest of India to have an exhausted global carbon budget at a time when it needs it like other developing countries (that is post-2030).
India, therefore, must now work harder with developing countries and push for an ambitious global deal which is equitable and saves the world from catastrophic climate impacts.
It must push for a principle-based emissions reduction target for all countries. This is the only way the world can remain within the planetary limits.
