Enough as a Climate Strategy

Climate strategy has a number for emissions: how much, by when. Demand is harder to pin down.

Most of the work goes into supply. Cleaner energy, more efficient engines and buildings, better grids, smarter allocation. This work is necessary, and much of it is where AI for Earth is doing real good: forecasting, optimising, monitoring at a scale no team could manage.

Demand is not ignored. Climate research already examines how demand can change while meeting human needs: the IPCC’s latest assessment gives a whole chapter to demand, services and wellbeing, including decent living standards for everyone. We want to explore one part of that work: whether helping households define and meet their own enough changes consumption and wellbeing over time.

Telling people to want less has a poor record, and it can fall hardest on those who already have least. We agree. That is why we do not start with less. We start with knowing what enough is, which for many families means more, and for others means seeing that what they are chasing is not something more things can provide.

Why efficiency alone does not settle it

Efficiency makes each unit cheaper in energy and materials. That is real progress. But cheaper units can mean more units. When coal was used more efficiently in the nineteenth century, total coal use rose rather than fell, and the pattern has been observed often since.

Our own evidence review rates this as supported, with qualifications. Efficiency does not always backfire; the size of the rebound varies, and policy can change it. But it is enough to say this: a plan that improves every unit and leaves the number of units open has no endpoint.

Why demand keeps growing

Madhyasth Darshan, our primary source, gives a direct answer. The wish to accumulate cannot be satisfied, because accumulation has no point at which it is complete. Liking and profit, likewise, have no point of satiation.

It also names what most extraction is for. Writing about oil, coal and the minerals dug out of the earth, the source observes that the main purpose of all this activity is the accumulation of comforts, for consumption.

And it is blunt about the result. People, out of a lack of discernment and out of temptation, tore open the earth and took out its coal, and the earth became heated. We declare that the earth is out of balance, the next page adds, but we do not accept responsibility for it, so the search for remedies never properly begins.

That is the source’s account, not a physical model of warming, which climate science supplies. We draw on the source for what it says about demand.

The point for climate work is not blame. It is that demand is not only a fact about the world. It is also a fact about understanding.

“Cleaner energy without enough has no endpoint.”

What “enough” means, precisely

“Enough” can sound like a mood. In the source it is close to a definition. Prosperity is producing more than is needed, consuming less, so that there is no lack.

Two things make this usable.

Needs are of two kinds. The body’s needs (food, clothing, a home, the tools to do one’s work, care when ill) are limited, and they can be counted. The self’s needs (security, respect, peace) cannot be met by any quantity of things, and only understanding settles them. A great deal of consumption is an attempt to meet the second kind with the first.

The first kind can be calculated. A family can list its body’s needs, put a yearly figure on each, add a reserve, and compare the total with what it produces. What is left over is prosperity. We have set out the method in How to calculate enough for a family.

Once enough is a number a household can work out, it is also a number a model can use.

What this could change in climate work

Some directions we think are worth testing:

• Demand scenarios anchored in need. Alongside scenarios that extrapolate today’s consumption, model a world in which households know their enough. How much of projected demand is countable need, and how much is the self’s needs being met with things?
• Enough as a variable, not a constraint. Rather than imposing a cap, measure how many households can state their enough, and whether they have it. Track that alongside per-unit efficiency.
• Separate need from accumulation in the data. Energy and material use for the body’s needs behaves differently from use for accumulation and status. Treating them as one number hides the part that could change.
• Surface first. The source distinguishes what the earth produces and renews from what is stored inside it, and points to the earth’s surface (sun, wind, flowing water, plants) for energy. Our essay How much should we take from the earth? sets this out in five steps.

We list “How can enough be built into climate models of demand?” as an open problem. It is one of the problems we most want to work on with climate scientists.

Enough is not austerity

This is the part most easily misread. A limit on the body’s needs is not a demand that the poor make do with less.

The same source that defines prosperity also describes prosperity for all: every family resolved and prosperous, through people completing one another. Knowing what enough is makes it possible to see clearly who does not have it. For a family without food or a home, enough means more, and soon.

The source also defines science itself in these terms: the knowledge that gives direction to physical prosperity and to the human goal. On that view, climate science and the question of enough are not separate subjects.

A protocol to try

Try the idea at home before modelling it. Take one part of your own energy use, such as travel, cooling or heating, and split it into two columns: what your body and work actually need, and what goes beyond that. Then ask how much of the second column you would still choose if you knew your family had enough.

How we would know if we are wrong

This fails if:

• households that work out their enough end up consuming no less than households that don’t;
• the body’s needs turn out not to be countable in practice, so “enough” cannot be stated without simply recording what people already use;
• the demand that understanding could change is too small a share of the total to matter for emissions, compared with supply-side change.

The third is a real possibility, and it would not make supply-side work less urgent. Our claim is not that enough replaces cleaner energy. It is that cleaner energy without enough has no endpoint.

An invitation

If you work on climate models, demand-side mitigation or AI for Earth, we would like to test this with you: what share of demand is countable need, and what happens to it when a household knows its enough. See also Beyond engagement and the spec. Build with us →

Limitations

• We have not yet measured how household understanding of enough changes energy or material use. This is a hypothesis.
• Individual and household demand is only part of total demand; industry, infrastructure and public spending matter too, and this essay says little about them.
• The source’s account of the earth’s heating is not a scientific climate model. We draw on it for the link between understanding and demand, not for physical claims.
