The aim is to promote positive long-term values that should improve the way a business is run by aligning its interests with those of society.
For example, in order to improve its effect on the environment, a company may introduce measures to reduce its carbon footprint, to minimize the use of finite resources or to eliminate waste. To improve the way it plays its part in society, it may insist on minimum standards in labour practices in its supply chain, it may introduce policies to expand its gender diversity or it may fund projects that build its standing in the community. When considering governance issues, a company might focus on how it balances executive compensation with performance, it might assess how ethical its operations are or it may improve transparency in its financial reporting.
Over the long term, it is believed that a more principled company culture that ultimately makes it more sustainable will improve the financial performance of that business, creating a win-win for all stakeholders. That is why the global ESG investing market was estimated to have grown to more than $25 trillion in size by 2023.
Sustainable investment funds that invest in a range of underlying companies may choose to exclude certain industries or sectors that don’t comply with ESG principles, such as gambling, tobacco or controversial weapons. But they may also choose to favour companies that have a strong ESG rating, that have made a conscious efforts to develop better behaviour along defined guidelines, such as those laid out in the United Nations 17 Sustainable Development Goals.
Impact investing goes one step further, because it favours companies that intentionally make a measurable positive contribution towards solving environmental or social problems alongside a financial return. It fills a funding gap when traditional philanthropy and government aid might be insufficient. Investments could be in healthcare, education, recycling, social housing, sustainable agriculture or climate change action. For example, investing in a renewable energy company could positively impact climate change, whilst investing in a plant-based meat company could positively impact public health and the environment.
