Note: CO2e-reduction effects are the total effects of the combined national stimulus funds and the funds from the Recovery and Resilience Facility. The reduction effects are estimated partially and the estimated effects may thus be overlapping. Total reductions may diverge from the sum of individual reductions due to roundings of decimals. In addition, significant future reduction contributions from the green research and development programs must be expected of. table 1.13. For instance, development of brown and green refinery can potentially deliver a reduction of 2 Mt CO₂ by 2030 if the preliminary results hold true. Furthermore, the four green research missions might lead to significant potential greenhouse gas reductions in the near future, e.g. new Power-to-X solutions have the potential of reducing the Danish greenhouse gas emission with somewhere between 0.5 and 3.5 Mt CO₂ per year in 2030.
