> what would be the global policy on abortion?
The U.N. Human Rights Committee has a recent (2019) publication[1], "General comment no. 36, Article 6 (Right to Life)" that contains an entry that is relevant to this question.
Page two, item eight under "General Remarks":
"Although States parties may adopt measures designed to regulate voluntary
termination of pregnancy, those measures must not result in violation of the right to life of a pregnant woman or girl, or her other rights under the Covenant. Thus, restrictions on the ability of women or girls to seek abortion must not, inter alia, jeopardize their lives, subject them to physical or mental pain or suffering that violates article 7 of the Covenant, discriminate against them or arbitrarily interfere with their privacy. States parties must provide safe, legal and effective access to abortion where the life and health of the pregnant woman or girl is at risk, or where carrying a pregnancy to term would cause the pregnant woman or girl substantial pain or suffering, most notably where the pregnancy is the result of rape or incest or where the pregnancy is not viable. In addition, States parties may not regulate pregnancy or abortion in all other cases in a manner that runs contrary to their duty to ensure that women and girls do not have to resort to unsafe abortions, and they should revise their abortion laws accordingly. For example, they should not take measures such as criminalizing pregnancy of unmarried women or applying criminal sanctions to women and girls who undergo abortion or to medical service providers who assist them in doing so, since taking such measures compels women and girls to resort to unsafe abortion. States parties should remove existing barriers to effective access by women and girls to safe and legal abortion, including barriers caused as a result of the exercise of conscientious objection by individual medical providers, and should not introduce new barriers. States parties should also effectively protect the lives of women and girls against the mental and physical health risks associated with unsafe abortions. In particular, they should ensure access for women and men, and especially girls and boys, to quality and evidence-based information and education on sexual and reproductive health and to a wide range of affordable contraceptive methods, and prevent the stigmatization of women and girls who seek abortion. States parties should ensure the availability of, and effective access to, quality prenatal and post-abortion health care for women and girls, in all circumstances and on a confidential basis."
