Voluntary Carbon Market Rankings 2025

Is the voluntary carbon market finally ready to grow up?

It has been a depressed year for transactions, but winners of Environmental Finance's annual Voluntary Carbon Market rankings see hope amid increasing levels of government oversight. Genevieve Redgrave reports

With preparation beginning for a suspected demand "surge" over the next year, new challenges are emerging in the Voluntary Carbon Market (VCM).

While market participants remain optimistic about incoming integration with compliance markets and digitalisation, they have urged for greater standardisation and clarity.

Environmental Finance's Voluntary Carbon Market Rankings are an annual poll of the market, in which participants vote for the leading companies and initiatives that exhibit best practice or innovation.

This year saw high interest, with 3365 votes across 23 categories.

EcoSecurities and Numerco are the biggest winners this year with two awards each. Some new winners were also awarded, including Triangle Digital, Abatable and Tullett Prebon.
