Emissions from energy combustion increased by 423 Mt, while emissions from industrial processes decreased by 102 Mt. In a year marked by energy price shocks, rising inflation, and disruptions to traditional fuel trade flows, global growth in emissions was lower than feared, despite gas-to-coal

The materials and energy needed to produce EV batteries explain much of its heavy carbon footprint. EV batteries contain nickel, manganese, cobalt, lithium, and graphite, which emit substantial amounts of greenhouse gases (GHGs) in their mining and refining processes.

Although many fully electric vehicles (EVs) carry "zero emissions" badges, this claim is not quite true. Battery-electric cars may not emit greenhouse gases from their tailpipes, but some emissions are created in the process of building and charging the vehicles. Nevertheless, says Sergey Paltsev, Deputy Director of the MIT Joint Program …

The mining fleet is one of the industry's primary sources of on-site greenhouse gas (GHG) emissions. Mobile mining equipment at a surface mine can account for up to 30 percent of on-site GHG emissions—or up to 80 percent if the mine doesn't have contiguous smelting or refinery facilities.

Widespread decarbonization efforts across industries could create major shifts in commodity demand for the mining industry. And the mining sector, responsible for 4 to 7 percent of greenhouse gas (GHG) emissions globally, will also face pressure from governments, investors, and society to reduce emissions.

Nuclear power reactors do not produce direct carbon dioxide emissions. Unlike fossil fuel-fired power plants, nuclear reactors do not produce air pollution or carbon dioxide while operating. However, the processes for mining and refining uranium ore and making reactor fuel all require large amounts of energy.
