A pathway to carbon-negative mining. | April 11, 2023 | 8:35 am. According to the International Energy Agency, the clean energy transition will require up to 20 times more critical minerals, such as nickel, copper, cobalt, lithium, and others by 2040. That means more mining is required to achieve decarbonization goals.

TSMC alone uses almost 5% of all Taiwan's electricity, according to figures from Greenpeace, predicted to rise to 7.2% in 2022, and it used about 63m tons of water in 2019. The company's water ...

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 …

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. Large mining haul trucks can …

They are also needed to help power the world's electric grids, because renewable sources, such as solar and wind energy, still cannot provide energy 24 hours a day. The market for lithium-ion ...

In an attempt to shed its reputation as an environmental polluter, the mining industry is increasingly deploying greener technologies to ensure its operations are more energy efficient and have a less degrading impact on the environment. Here is a round up of some of the best green technologies on the market. Heidi Vella July 25, 2013.

A new study did a deep dive into the emissions from the full life cycles, from petroleum extraction to mining, of both electric cars and fossil fuel-powered cars. The result is unsurprising but ...

The company – first established in the backyard of the University of British Columbia as Carbin Minerals – developed a technology that significantly accelerates …

Emissions within mining can be broken down into three broad types: Scope 1 (emissions from diesel), Scope 2 (emissions from electricity generation), and Scope 3 (emissions from the supply chain and transport). Today 40 to 50 percent of CO2emissions come from diesel used in mobile … See more

Plumes of sediment stirred up by mining could contaminate sea water and damage fishes' gills and filter-feeding apparatus, says Amon. The same problems could occur when mining waste is thrown ...

The energy transition presents unique challenges for metals and mining companies, which will need to innovate and rebuild their growth agenda. ... Climate commitments made in Glasgow have entrenched the net-zero target of reducing global carbon emissions (aimed at preventing the planet from warming by more than 1.5°C) as …

The mining industry is a highly carbon-intensive industry and a significant emitter of greenhouse gases (GHGs). When we look at the carbon profile of the mining industry, we see that Scope 1 and 2 emissions account for 4 to 7% of total global GHG emissions and when we include Scope 3, this rises to 28%. 2 The mining industry has …
