Canada is struggling to get a key tool in place for major carbon capture and storage (CCS) projects, said a representative of one of the largest such ventures, as the country seeks to launch incentives vital to cutting emissions from Alberta's oil sands. A government fund has told the Pathways Alliance, comprised of the six largest oil and gas producers in Canada, that their project is too large and too risky for a contract for difference, a tool which would lock in future carbon credit prices, the representative told Reuters.
