There’s a lot of talk about the impact of cryptocurrency on the environment. Many believe environmental myths that label all digital currencies as harmful. But when we look closely, we find big differences among them. It’s also useful to compare them to traditional sectors like gold mining, which has its own environmental issues. This part aims to clear up common myths by comparing Bitcoin to other industries.

Debunking Myths Surrounding Cryptocurrency

About 140 million metric tons of CO2 emissions come from cryptocurrency mining each year. This accounts for roughly 0.3% of the world’s greenhouse gas emissions. The emissions are more than those of some countries, including Argentina and the Netherlands. Critics often say that digital currencies have a bigger environmental impact than physical cash. In fact, some studies suggest they could be three times worse. This concern has led some places, like New York, to ban certain mining operations.

Comparing Cryptocurrency to Other Industries

When we compare Bitcoin mining to traditional mining, we discover interesting facts. Environmental economist Benjamin Jones pointed out that, between 2016 and 2021, the environmental damage from mining Bitcoin sometimes exceeded the value of the currency itself. However, energy use varies greatly among different cryptocurrencies. The table below shows how much energy each one uses per transaction. This highlights the industry’s move towards sustainable practices:

Cryptocurrency	Energy Consumption per Transaction (KWh)
IOTA	0.00011
XRP	0.0079
Chia	0.023
Dogecoin	0.12
Cardano	0.5479
Litecoin	18.522
Bitcoin Cash	18.957
Ethereum	62.56
Bitcoin	707

Ethereum has recently made a major switch to greener mining methods. They aim to reduce carbon emissions by 99%. This could offer a path forward for the whole industry. So, understanding the true environmental impact of cryptocurrencies requires us to avoid common myths and look at the facts.
