Suzlon Energy Ltd entered the ranking of 100 of the world’s greenest corporates in Canada-based media and research firm Corporate Knights’ Global 100 Index 2026 for the first time.
Suzlon’s sustainable revenue growth from 2022 to 2024 nearly doubled from INR 59.5 billion (US$647 million) to INR 108.5 billion (US$1.2 billion), resulting in a strong momentum score of 77.8 per cent relative to its peers, according to Corporate Knights.
Sustainable revenue growth is a new metric introduced by Corporate Knights in this year’s index to measure how fast companies are growing their revenues from low carbon products.
The Pune-based firm, which was primarily a wind energy company, expanded into the solar market in 2016, by winning bids for 210 megawatts (MW) of solar projects in Telangana, India.
The company has derived 100 per cent of its revenue and investment from clean energy, as new capacity additions in Asia Pacific are projected to expand by 670 gigawatts (GW) from 2025 to 2030, with solar photovoltaic sources from India accounting for nearly three-quarters of the total.
The region’s surge in wind power is also due to India’s uptake, positioning the world’s most populous country as the third-largest wind manufacturing hub globally.
However, Taiwan High Speed Rail Corp is the greenest company in Asia Pacific in the yearly index, maintaining its global ranking from last year, and after topping the survey in 2023. The 18-year old firm is growing its revenues derived from investments soley from sustainable means.
Australian metals recycler Sims Limited, which held the top spot last year, slipped 46 places as it scored poorly in its sustainable revenue momentum. But the 108-year old firm still derived its revenue and investment from low carbon sources.
The Global 100 was announced on the sidelines of the World Economic Forum in Davos. The annual line up quantitatively compares and ranks the world’s largest publicly traded companies, equally emphasising the impact of a company’s operations and its core products and services on people and the planet.
It assessed 8,359 companies with more than US$1 billion in revenues against 25 sustainability indicators, including revenue and investment derived from sustainable sources, taxes paid, how much value is created with fewer carbon-based fossil resources, and racial and gender diversity.
China’s 12 ranked companies continued to be dominated by electric vehicles (EVs), just like last year, along with new entrants for battery making. The Asian super power’s manufacturing dominance has been a driving force behind the rapid adoption of affordable EVs, accounting for almost 80 per cent of global production.
Shanghai-headquartered NIO Inc, Li Auto Inc from Beijing and Guangdong’s XPeng Inc are still in the top 50 of the Global 100 list of the world’s greenest corporates. EV companies Zhejiang Leapmotor Technology Co Ltd and Seres Group Co Ltd, as with lithium-ion manufacturers Contemporary Amperex Technology Co Ltd and Gotion High-tech Co Ltd made their debut in the list this year.
Singapore real estate firm City Developments Limited (CDL), which fell 30 spots from last year, generated more than 50 per cent of its revenues from clean energy and over 70 per cent from sustainable investments.
The 63 year-old firm’s local rival CapitaLand was not part of the index this time, as with the previous year.
Western firms remain the world’s most sustainable companies
The number of Asia Pacific companies that made it to the index increased from 22 to 27 this year. This is likely due to Asia’s rise as the world’s economic engine and a reflection of Asian companies increasingly seeking sustainability solutions, said Toby Heaps, president of Corporate Knights.
“Asia Pacific now makes up the majority of sustainable revenue and investment globally, and increasingly this is reflecting in what is reported in companies headquartered in the region. We will continue to see more and more companies from Asia Pacific in future global 100 rankings,” Heaps told Eco-Business.
Europe and the United States, as well as Canada continue to dominate the list. Thirty-seven firms on the Global 100 Index are from Europe, 20 are from the US and 9 from Canada.
ERG SpA, an Italian power generation company, rose from 18 to rank first as the world’s most sustainable company.
Amid extreme wartime volatility and the sale of all its fossil fuel assets, ERG managed to increase its power output from wind and solar sources by more than 2,000 gigawatt-hours between 2022 and 2024.
Copenhagen-based jewelry maker Pandora took second place, reflecting its shift to lab-grown diamonds and 100 per cent recycled silver and gold. Madrid-headquartered EDP Renovaveis SA placed third. Both companies rose significantly from their 2025 rankings, with the former at 48th place while the latter ranked at 38th.
