China has approved the construction of what will become the world’s largest hydropower dam in Tibet. Located in the lower reaches of the Yarlung Tsangpo river, it could generate three times more energy than the Three Gorges Dam – also built by China - and currently the worlds’ biggest. This Inquiry examines how important hydropower is for China’s economy, whether it will meet its climate goals and whether this new dam is a “safe project that prioritises ecological protection” as China claims. We look at how it’ll be built, and why some in neighbouring countries have concerns.
