Currency conversions

Updated this week

When submitting CTB spend documentation that shows purchases made in a currency other than USD, companies are required to convert the amount of spend to USD. The date of the currency conversion date must align with the date that the company made the purchase.

For example, if a company purchased onsite solar panels for €100,000 on June 1, 2024, the company should convert this amount to USD for June 1, 2024.

We recommend using a currency conversion tool that can convert historical conversation, such as Oanda or Wise.
