Educating Girls
Educating girls is a human right and one of the most powerful development goods there is. Its climate effect is real but downstream — a consequence of freedom, never a reason to ration it. This is the solution most easily, and most dangerously, misread.
The effect arrives across lifetimes. This is a gift to people you will not meet.
Origins
For most of history, in most of the world, girls were not schooled. The idea that a girl has the same right to learn as her brother is, at civilisational scale, recent — and still unfinished.
The twentieth century saw enormous, uneven progress: mass primary schooling spread across the globe, and the gap between girls and boys at the primary level has nearly closed in much of the world. But secondary education, which is where most of the cascade lives, remains far from universal for girls in the poorest regions, and the barriers are depressingly concrete. School fees. The cost of uniforms and books. Long or unsafe journeys. The absence of separate toilets, which quietly pushes girls out at puberty. Early marriage. The expectation that a daughter’s labour belongs at home. And, in some places, deliberate prohibition.
The evidence base that turned this from a moral cause into a measured climate solution came largely from demographers, who documented across decades and dozens of countries the tight relationship between girls’ educational attainment and later, freely chosen, smaller families. When Paul Hawken’s Drawdown team modelled it, girls’ education and family planning together ranked near the very top of their list — a finding that surprised almost everyone, and that has been argued over ever since.
What it actually is
The mechanism is not complicated, and it is worth stating plainly because it is so often distorted. When girls complete their education — especially secondary school — a cascade of good things follows, each valuable entirely on its own terms. They marry later if they choose to marry, and later by their own decision. They have children later, if they choose to have them. They earn more, know more, command more standing in their households and communities, and are far better placed to withstand shocks, including the shocks of a changing climate.
Somewhere in that cascade, as a side effect of expanded freedom, average family sizes tend to fall. Over decades and across a whole society, that bends the population curve gently downward from where it would otherwise have gone. Fewer people, over a long horizon, means lower emissions. That is the climate link, and it is genuine.
But notice the order of things, because the order is the entire ethical content of this page. You do not educate girls in order to reduce births in order to cut carbon. You educate girls because education is their right and their good, and a freer, richer, healthier life is the point. The slower population growth is a consequence of that freedom, not its purpose. Reverse those and you have left the realm of a climate solution and entered the ugly history of population control.
Project Drawdown, which ranks this among its highest-impact solutions, is emphatic on exactly this point, and so are we.
The numbers
Where Drawdown places it. In the original Drawdown analysis, educating girls and family planning ranked sixth and seventh among all climate solutions. In the later revision, the two were combined into a single “Health and Education” solution credited with roughly 85 gigatons of avoided emissions by 2050 — among the largest figures in the entire framework.
What the figure actually represents. It is the emissions difference between two United Nations population projections — a “medium” and a “low” fertility path — not the output of a coercive target. The gap between those paths is what universal education and voluntary reproductive healthcare, taken together, could plausibly deliver as a by-product of expanded rights.
An honest caveat. Drawdown split that combined figure evenly between education and family planning, and the split is, by their own account, somewhat arbitrary; the two are deeply entangled and hard to separate cleanly. The precise gigatonnage should be read as an informed estimate, not a hard measurement.
The development dividend, which needs no climate justification at all. An additional year of a girl’s schooling is associated with higher lifetime earnings, lower child and maternal mortality, better child nutrition, and greater resilience to disaster. These are the reasons that matter first.
Why it matters
We have to be careful here in a way we are careful almost nowhere else on this site, because this is the solution where good intentions have historically curdled into something monstrous.
The twentieth century is littered with “population” programmes that treated the fertility of poor women, and especially poor women of colour, as a problem to be managed by the state: coercive sterilisation campaigns, targets and quotas, incentives that shaded into force. That history is real, it is recent, and it is a permanent warning. Any climate argument that slides toward “there are too many people” is not only ethically rotten; it is almost always aimed at the people who did least to cause the crisis and can least defend themselves against the remedy.
So we hold to the order of things, without exception. Educating girls is a good because a girl has a right to learn, to earn, to decide the shape of her own life. Full stop. That it also, over generations, eases pressure on the atmosphere is a gift — but a gift that arrives only because we honoured the right, and that vanishes the instant we try to seize it by force. A birth prevented by coercion is a wrong. A birth not conceived because a woman freely chose a different life is not a climate policy at all; it is simply her life.
Project Drawdown states this outright: it does not advocate for “small” or “ideal” family sizes, and it names such policies as potentially racist, classist, or coercive. It advocates, as we do, for the full bodily autonomy of every woman and girl to decide whether, when, with whom, and how many children to have. Get that right and the climate takes care of itself, quietly, over generations. Get it wrong and you have betrayed both the girl and the cause.
This sits at the heart of what we mean by Our Humanity. The most powerful thing you can do for the future of the living world may also be the most humane: give a girl a full and free life, and trust her with it.
What it actually takes
Remove the concrete barriers. Most girls who leave school do not leave for lack of ambition; they leave because of a fee, a uniform, a missing toilet, an unsafe road, or a marriage arranged over their heads. Each of these is fixable, and fixing them is unglamorous, cheap, and effective.
Fund secondary school, not just primary. The cascade of benefits — later childbearing, higher earnings, greater resilience — concentrates in the secondary years. Near-universal primary enrolment is a real achievement; it is also not enough.
Keep girls safe and dignified at school. Separate sanitation, protection from harassment, and support through puberty do more to retain girls than almost any curriculum reform.
Fund it as a right, not as a lever. Education budgets should be defended because education is owed to children, and framed that way. The climate co-benefit is a reason to invest more, never a reason to instrumentalise a girl’s schooling toward a demographic target.
Pair it with voluntary reproductive healthcare. Education expands what a young woman can choose; access to family planning lets her act on the choice. The two together are far more than the sum of their parts.
Where it matters most
The gap is widest, and the opportunity greatest, in the regions where secondary schooling for girls remains least available — and we name them not as problems but as places where a right is still being withheld and could be extended.
Across the Sahel and the East African Rift, girls’ secondary completion rates remain among the lowest in the world, held down by poverty, distance, and early marriage — and it is precisely here that expanded access delivers the largest cascade of benefit, for the girls first and the atmosphere long after.
In the Congo Basin, schooling competes with conflict and displacement, and keeping girls in classrooms is as much a matter of stability as of curriculum.
Across the Western Ghats and the wider Indian subcontinent, and in the mountain communities of the Himalaya, dramatic gains in girls’ enrolment sit alongside stubborn pockets where distance, cost, and custom still cut a girl’s education short.
How to tell it’s being done well
Is it framed as a right, or as a lever? A programme that talks about girls’ futures, earnings, and choices is on solid ground. One that leads with birth rates or carbon is pointed the wrong way and should be treated with suspicion.
Does it reach secondary school? Primary enrolment is table stakes. The transformative effects live in the secondary years, which is exactly where funding thins out.
Does it remove real barriers? Fees, sanitation, safety, distance, early marriage — the honest programmes target these, not slogans.
Is participation voluntary and dignified at every step? Anything that pressures, targets, or incentivises fertility outcomes has crossed the line, however it is dressed up.
Are the girls and their communities the authors, or the objects? The best programmes are shaped by the people they serve. The worst are done to them.

Questions
Why is educating girls considered a climate solution?
Because when girls complete their education, especially secondary school, they tend to marry later and have children later and by their own choice. Over decades, across a whole society, that gently lowers population growth from where it would otherwise be, which lowers emissions. The effect is real but it is a downstream consequence of expanded freedom, not the reason to educate girls.
Isn't this just population control with a friendlier name?
No, and the distinction is the whole point. Population control means the state treating people's fertility as a problem to manage, often coercively. This is the opposite: securing a girl's right to learn and to decide her own life. Any slower population growth comes only because the right was honoured, and disappears the moment coercion enters.
Where does the large emissions figure come from?
It represents the difference between two United Nations population projections, a medium and a low fertility path, that universal education and voluntary reproductive healthcare could plausibly deliver together. Drawdown split the combined figure between education and family planning somewhat arbitrarily, so the exact gigatonnage is an informed estimate rather than a hard measurement.
What actually keeps girls out of school?
Rarely a lack of ambition. Usually concrete, fixable barriers: school fees, the cost of uniforms and books, long or unsafe journeys, the absence of separate toilets, early marriage, and the expectation that a daughter's labour belongs at home.
What matters most to focus on?
Secondary education, and removing the physical barriers that push girls out. Primary enrolment has nearly reached parity in much of the world, but the transformative benefits concentrate in the secondary years, which remain underfunded.
