More than $500 million are being directed at carbon storage. This includes the development of technologies for the capture and study of watersheds where carbon storage could be achieved. This also includes large-scale demonstration projects, particularly Shell's Quest project, which we were discussing a few minutes ago.
There are also factors that involve international cooperation, particularly with the United States, but also through certain international mechanisms. The goal here is to move research forward. We have invested a great deal in research to ensure the monitoring of carbon dioxide storage sites, in the Weyburn-Midale region, where almost 20 megatonnes have already been permanently stored in old oil and gas reservoirs.
