Coal an increasing financial risk for big mining houses as divestment from the fossil fuel gains traction, says report
Coal assets could be worth less than half of their current market value if the world agrees tougher climate targets and curbs on the use of the fuel, investment bank HSBC said in a report today.
HSBC said that the value of coal assets owned by global mining conglomerates such as BHP Billiton, Rio Tinto, Anglo American and Glencore Xstrata might be slashed by around $20 billion if governments decide that much of the worldâs future coal production should be left in the ground.
The possibility that many mines and power stations that burn the fuel could become âstranded assetsâ gained much greater traction in the past year, as finance institutions such as the World Bank curbed lending to coal and large investors pulled money from the sector.
âThe latest climate science has reemphasised that the carbon contained in global fossil fuel reserves is far greater than the available âcarbon budgetâ for the rest of the 21st century. Coal is particularly exposed as it is the most carbon- intensive fuel,â HSBC said in todayâs report.
The growth of shale gas and renewables, as well as tighter air pollution regulations in countries such as China, had also heightened the risks for coal, the report said.
âIt is fair to say that the long-run future of coal is now âin playâ in commodity and equity research markets,â the report said, adding: âthis is not to say that a new consensus has emerged, and we would describe the debate as at an embryonic stage.â
Despite acknowledgement that the value of the worldâs vast coal infrastructure could be eroded in future decades, the fuel is expected to retain its dominant share in the worldâs energy mix, particularly in developing countries.
The International Energy Agencyâs annual outlook for coal published in December said the fuel is likely to replace oil as the dominant source of energy by the end of the decade.
âThis matters because a coal plant, once built, stays around for decades. This carries grave implications for climate change, for in its current form, coal is simply unsustainable,â the IEA chief Maria van der Hoeven said ahead of a clean energy summit in Abu Dhabi today.
She said that without carbon capture and storage and a meaningful carbon price, runaway climate change will be unavoidable.
âEven though we’ve known how to build efficient coal-fired power plants since the 1960s, most of the coal plants built since then — and a large proportion of the ones being developed today — are of the inefficient kind,â she said.
The increasing financial risk of exposure to coal will be discussed at the World Economic Forumâs annual meeting in Davos this week, where the UN will once again urge world leaders and large companies to do more to cut carbon emissions as part of a future climate pact.
The main problem for policymakers is that coal-fired power is usually far cheaper than gas, nuclear and renewables, while countries such as China and India have large domestic reserves of the fuel in addition to cheap imports from Indonesia.
In large exporting countries, the coal industry also enjoys strong political support.
Last year’s general election in Australia saw the winning party campaign against carbon trading, and Prime Minister Tony Abbott opposes many measures that could harm the country’s huge mining industry.
And even in Germany, which is pushing ahead with its âEnergiewendeâ or transition to green energy, new coal-fired power plants are still being added to the energy mix.
