Which are the most eco-sustainable companies in the world? Here is the 2025 ranking of the most environmentally sustainable companies within and outside our borders.
What are the most sustainable companies in the world in 2025? The environmental issue continues to be central to the global political-economic debate, even if Donald Trump’s return to the White House could lead to a reversal of the course set in recent years.
First, we need to specify the underlying concept. An eco-sustainable company is a company that adopts practices and strategies aimed at reducing its environmental impact, while promoting ecological, social and economic sustainability.
This means that an eco-friendly company operates in a way that preserves natural resources, reduces CO₂ emissions and minimizes waste, without compromising the ability of future generations to meet their needs.
Now in its 21st year, Corporate Knights’ annual Global 100 has ranked the world’s most sustainable companies in 2025, evaluating companies around the world based on several criteria including greenhouse gas emissions reduction and renewable energy use.
"Corporate Knights’ Global 100 ranking of the world’s most sustainable companies, now in its 21st year, shows that leading companies continue to increase their investments in the green transition - the press release states -. Even with higher interest rates in recent years, leading companies have expanded their sustainable investments, which has led to a growing share of revenue from sustainable sources".
Let’s take a closer look at the greenest companies according to this survey, taking a look at the 2025 ranking of sustainable companies around the world.
The ten most sustainable companies in the world
The Global 100 is an annual ranking of the 100 most sustainable companies in the world published by the Canadian company Corporate Knights. Launched in 2005, this list recognizes companies that excel in environmental, social and governance (ESG) sustainability practices, based on scientific and transparent criteria.
The 2025 ranking of the most environmentally sustainable companies was presented - as is now customary - during the World Economic Forum in Davos.
According to the ranking drawn up by Corporate Knights, these would be the 10 most sustainable companies in the world in 2025.

HERE THE 2025 RANKING COMPLETE
France’s Schneider Electric SE tops the 2025 Global 100 list, moving up from seventh place last year thanks to a high level of sustainable investments and revenues, its leading gender diversity performance and the low carbon intensity of its production.
Last year’s top-setter, Australian waste management company Sims Ltd., is ranked second this year, while Danish wind producer Vestas Wind Systems S/A is third. Both Sims and Vestas are pure-play companies with 100% of their revenues sustainable and 100% of their investments allocated to green projects.
Fun fact: among the ten most sustainable companies in the world, only one is American, Enphase Energy Inc, despite the legislation - now targeted by Trump - that has led to almost 300 billion dollars of private sector investments in clean energy.
