SoNick – the ESG battery

Category ESG Battery

ESG (Environmental, Social, and Governance) is a term that is often used by ethical investors to evaluate a company’s sustainable and ethical performance when they are investigating the long term investability of a company.

A crucial part of our new energy transition is the usage of batteries to store energy, either as backup power, to stabilize the grid or in EV’s. This transition will involve trade-offs and by adhering to ESG principles companies can make sure their governance covers factors that make sure that the net result of this transition is positive from the environment and social angles.

ESG markers are like biomarkers that tell us how healthy our bodies are. ESG markers in a company are used to give us an indication of what ethical and sustainable principles a company is utilising.

Many battery manufacturing companies claim their batteries will be good for the environment, however they fail many of the ESG markers. Likewise, many battery manufacturing companies themselves fail many of the social and governance ESG markers that modern ethical investors are looking for.
