The documents below are from the Sigma Global era (2007-2021). Sigma Global was an environmental markets advisory firm with offices in Australia, the UK, and the Netherlands. The EMA team worked there before founding EMA independently.
Sigma Global was acquired by GreenCollar in 2021. These documents are preserved here as a public record of that earlier work, much of which is no longer available online.
