This report from the UN Development Programme (UNDP) and UN Environment Programme (UNEP) offers advice to policymakers on present evidence to make the case for environmental investment.

Environmental sustainability is often seen as a luxury that governments cannot afford. Environmental managers often find selling their sector to macroeconomic decision-makers difficult.

But a healthy environment is vital to pro-poor economic growth, and economic evidence can encourage policymakers to buy in to policies that promote sustainable use and management of the environment.

The data requirements for making the economic case for environmental investment are summarised and advice is provided both for accessing relevant information, and presenting it as a convincing argument to treasuries and finance ministries.
