Economic studies and reports on topics such as coffee price volatility, risk management and the effects of tariffs on the coffee trade are published on a regular basis. The Coffee Exporters Guide, which was compiled by the ITC with the ICO and other organizations, covers trends such as niche markets, organic and fair trade labelling, codes of conduct and environmental issues. The ICO Step-by-Step Guide to promote consumption is another resource which has resulted in investments of some US$30 million promotion programmes and workshops in producing countries, with further investments in the pipeline.
