79% of Companies Now Disclose Climate Risks — But Fewer Commit to Net-Zero, According to 100 Best Data

Climate Week NYC 2025 is underway, and corporate climate leadership is front and center. At 3BL, we know that the 100 Best Corporate Citizens list is more than recognition — it’s a data-driven snapshot of where companies stand on critical climate issues, and where they still have work to do.

Take corporate disclosure of climate change risks. Just four years ago, in 2021, only 25.7 percent of Russell 1000 companies disclosed quantifiable climate risks. Today, in 2025, that number has jumped to 79.1 percent. Meanwhile, companies offering only “general” disclosures have dropped from nearly 40 percent to just 15 percent. The message is clear: companies are moving from vague statements to concrete, measurable accountability.

But when we look at approved net-zero Science Based Targets (SBTis), the picture is more complicated. Progress peaked in 2023, when 18.2 percent of Russell 1000 companies had a net-zero SBTi commitment. By 2025, that figure has slipped back to 12.8 percent. While transparency is on the rise, the momentum behind ambitious, science-aligned targets is showing signs of stagnation.

These trends highlight both the achievements and the gaps in corporate climate action. Companies are more willing than ever to disclose their risks, but fewer are following through with rigorous, future-focused climate commitments. The 100 Best Corporate Citizens list reflects this reality, showcasing the companies leading the way while offering benchmarks for others to catch up.

As global leaders, activists, and businesses gather this week in New York, the data reminds us: leadership is not static. It evolves with expectations, accountability, and action. For companies, that means the bar is higher than ever — and the time to act is now.
