Definition

Rio markers are policy markers in the OECD DAC's statistical system, introduced in 1998, by which donors score each aid activity for its contribution to the objectives of the three Rio Conventions: climate change mitigation, climate change adaptation (added later), biodiversity and desertification. Activities are marked "principal" (the objective is fundamental) or "significant" (an important but secondary objective).

Overview

How it is used

DAC statistics on Rio-marked flows feed UNFCCC finance reporting, GBF resource mobilisation tracking, and civil society accountability analyses of donor environmental commitments.

Why it matters

What gets counted as environmental aid shapes what gets funded; Rio markers are the quiet machinery behind the headline numbers.
