This Policy Brief underlines the problem of gas flaring in the petroleum sector, and draws important lessons from Ecuador for Uganda in the conversion of waste to wealth. The oil industry is associated with greenhouse gas emissions through AG flaring and other carbon monoxide and carbon dioxide emissions, with resulting implications for global warming. The industry now faces a new challenge: the demand for alternative green energy; and the demand for zero AG flaring. Therefore, as Uganda ascends to the production phase, and hopes to implement its Green Growth Strategy, certain investments, structures and preparations are necessary to realise the spirit of the law and global initiatives. Three aspects are addressed here: the problem of AG flaring is summarised; project lessons from Ecuador are articulated; and lessons drawn for Uganda. The concluding section makes recommendations on what Uganda needs to learn and do.
