- A range of energy sector emissions mitigation from CCS (at top) are applied to a range of algae production scenarios (listed at left as percentages of total feed consumption). Yellow shaded cells indicate warming of 2.0 ± 0.2 \(^{\circ }\)C. Red shaded cells indicate warming projections in excess of this threshold, while green shaded cells indicate sub-1.8 \(^{\circ }\)C warming
