Yes and we still have a good chance to keept it well below 5. For most technologies emitting CO2, we now have emission free replacements, so if we strongly push for using them, we do have quite a fighting chance.
Make the transition to those technologies a top priority in each sector. Like installing solar and wind energy as fast as it can be done. House heating should be done with heat pumps in most locations, so any new heating system installed should be low CO2.
Make a big push for electric cars. Norway is at over 50% electric in the new cars already. But for that, the car manufacturers need urgently to ramp up their production capacity for electric cars.
