The Greens need to stop this 'hard bargain' stance of theirs. It has cost us progress on important matters in the past and would cost us progress on this topic now.
"Le mieux est l'ennemi du bien" --Voltaire. In english: 'The best is the enemy of good'. Don't prevent progress in the direction everyone needs in pursuit of the perfection up front. You won't get perfection and you styme any progress in its pursuit.
