Making one tonne of aluminum at plants using power generated by burning coal, the main source for those in China and Australia, releases up to 18 tonnes of CO2 equivalent.
For gas-powered plants in the Middle East, the figure is between five and eight tonnes, but for those running on hydro-power it is lower still at only around two tonnes.

Det blir dyrere og dyrere å betale for co2, og premiumen for aluminium produsert med vannkraft vil øke.
"As a result, there is a rising demand from downstream players of aluminium for “green metal”, buoyed by customers’ own need to reduce carbon footprints across the board. Producers of environmentally-friendly aluminium, made using renewable energy rather than fossil fuels, are starting to be in a position to charge premium prices for what are lower carbon metals whilst boosting their own green credentials. The term low carbon can encompass both recycled and primary aluminium that has a CO2 footprint way below the current industry average index standing at around 11.5 tons CO2 per ton of aluminium produced."

In 2005, the amounts of hydro and coal power used to make aluminum were roughly the same at around 200,000 gigawatt hours each, according to the International Aluminum Institute (IAI). A decade later the hydro figure had changed little, whereas coal had leapt to around 450,000 GWh.
That was largely due to expansion in China, which now accounts for around 55 percent of global aluminum output. The country’s plants rely on coal for 90 percent of their energy needs.
With gas use also rising due to new plants in the United Arab Emirates, Bahrain, Qatar and Saudi Arabia, hydro’s share of the mix slipped to 30 percent in 2015, according to IAI data. This compared with 59 percent for coal and nine percent for gas, with nuclear energy accounting for the remaining two percent.
But at the same time, companies including iPhone maker Apple (AAPL.O) and Toyota (7203.T) are working to reduce the carbon footprint of their products. A number of aluminum makers are therefore positioning themselves to benefit by offering metal with guaranteed low emissions.
