That means China would become a net-zero carbon emitter, which researchers in Reuters report said could slow global warming by 0.2-0.3 degrees Celsius this century. Citi analysts said in a recent report that much of China’s effort to reduce emissions will translate into greater use of cleaner energy sources, while reducing the country’s reliance on coal. That means companies in the renewable energy space will likely benefit in the long term, they added. “Solar- and wind-related companies should be the biggest and most obvious beneficiaries from the shift to cleaner energy,” the report read.”Beyond these, we like gas distributors …, electric auto manufacturers and certain related industrial entities,” it added.Citi’s top “buy” ideas are five such Chinese companies:Solar glass firm Xinyi Solar;Wind turbine manufacturer Goldwind;Gas distributor ENN Energy;Electric vehicle maker BYD;and Ganfeng Lithium, a supplier of lithium hydroxide that’s used to make batteries in electric vehicles.Losers of China’s green goalsChina is currently reliant on coal for energy, but it “emits the most carbon among the various energy sources,” said the Citi analysts.So, coal’s share among China’s energy mix is set to significantly decline in the coming decades for the country to reach its carbon neutral goal, they added.Citi estimated that the proportion of coal could fall from around 57.6% in 2019 to 15% in 2060, while that of oil could decline from 19.7% to 12.1% over the same period. Meanwhile, the share of natural gas and renewable sources are likely to increase, according to the projections.That means that businesses related to the “traditional energy types” would be “major losers” as demand for their products and services decline, said Citi analysts.”These include coal-fired power generators, oil producers, coal-fired power equipment companies as well as companies involved in rail transport,” they explained.The bank listed several companies with close links to the coal sector among its top “sell” ideas. Those include:Shenhua, a mining company;CR Power, a power supplier that uses coal as one of its energy source;Dongfang Electric, which manufactures power generators, including coal-fired ones;and Daqin Railway, which transports coal across China.Oil and gas firm Sinopec was also featured on Citi’s list of major losers of China’s energy transition.
