From what I've heard and read, Costa Rica has done excellent work in this direction.

GDP is low compared to many developed countries. But they have an innovative health care system that provides good outcomes with limited resources, inexpensive but healthy diet featuring rice and beans and fresh fruits and vegetables, a devotion to environmental preservation, and energy production almost entirely from renewables with bans on oil and gas exploration.

For these and other reasons, they are one of the Blue Zones where a surprisingly high number of people live to be over 100 years old.

The other factor in Costa Rica is political stability and low military spending. After their civil war in 1949, they constitutionally abolished the military (Article 12) which not only prevents military juntas from emerging but also enables spending on healthcare in a low GDP country.

All that said, Blue Zones are fake, driven by cohort effects and poor record keeping. https://www.demographic-research.org/articles/volume/49/27/

Hydropower is also a significant contributor to their low carbon energy generation profile.
