Khalifa and Climate

Long before "sustainability" became a policy word, the Qur'an set out a vocabulary for humanity's relationship with the earth that is at once theological and ecological. Adam and his descendants are named khalifa — a term usually rendered "vicegerent" or "steward" — and are told that they carry an amana, a trust that the heavens, the earth and the mountains declined to bear. These are not decorative metaphors. They are load-bearing concepts in Islamic thought about how a finite, shared planet ought to be treated, and they sit awkwardly next to a global food system that is now one of the largest drivers of greenhouse gas emissions, deforestation and biodiversity loss on record. This page asks what khilafa, amana and the Qur'an's language of balance and corruption have to say about that system — and where honest people, including committed environmentalists, disagree about what follows for an individual's plate.

Khalifa and amana

The word khalifa appears at the very moment of Adam's creation, when God tells the angels of an intention they cannot at first fathom:

The angels' objection is itself instructive: it anticipates precisely the kind of corruption and bloodshed that later becomes the Qur'an's recurring worry about human conduct on earth. God's answer is not a denial that this capacity for harm exists, but an assertion of a deeper knowledge and purpose behind the appointment. Elsewhere the Qur'an widens the address beyond Adam to humanity generally:

Stewardship here is bound to trial — the earth and its resources are a test, not a possession to be exhausted. This is reinforced by the Qur'an's separate but related vocabulary of amana, trust:

Commentators have read this verse in many registers — moral responsibility, religious obligation, free will — but an ecological reading, increasingly common among Muslim scholars and environmental organisations, treats the amana as encompassing the created order itself: air, water, soil, animals, the climate system. To hold something in trust is a specific legal and moral relationship, distinct from ownership. A trustee who depletes, pollutes or degrades what has been entrusted to them, even for short-term gain, has failed the terms of the trust regardless of whether any human court can prosecute them for it. That framing gives the discussion of climate change a theological register that goes beyond "environmentalism" as a secular value and treats ecological conduct as directly answerable to God.

Fasad fil-ard: corruption on the earth

If khilafa and amana describe the ideal, the Qur'an also names its failure. The phrase fasad fil-ard, "corruption in the land" or "on the earth", recurs across the text, most directly in a verse widely cited in contemporary Islamic environmental writing:

Classical exegetes read this verse in various ways — some emphasising moral and social corruption (injustice, tyranny, broken contracts) over what we would now call environmental damage specifically. That caution is worth preserving: it would be exegetically careless to claim the verse was "about" climate change in a modern scientific sense. But the structure of the verse is significant regardless of which referent is emphasised: corruption in the land and sea is explicitly traced to human hands, and the resulting hardship is described as a consequence, not an arbitrary punishment, with the stated purpose of turning people back towards right conduct. A second verse strengthens the moral logic without needing to specify mechanism:

Here fasad is tied concretely to the destruction of harth (tilth, crops) and nasl (progeny, livestock) — the very stock of agricultural and pastoral life. Whatever the verse's original polemical target, its content names crop and animal destruction as paradigm cases of corruption on earth, which is difficult to read as indifferent to contemporary questions of soil depletion, monoculture collapse or mass animal mortality under industrial systems.

An open letter's reading of fasad and the 14% figure

An anonymous Persian open letter to Shia Muslims, circulated as advocacy rather than as a ruling from any named jurist, reads «ولا تفسدوا في الأرض» — "do not spread corruption in the earth" (echoing 2:11 and 7:56, close in sense to the fasad fil-ard verses above) — as applying directly to the livestock industry's environmental footprint, citing deforestation and water depletion driven by feed and pasture expansion alongside a commonly repeated estimate that livestock accounts for roughly fourteen per cent of global greenhouse gas emissions. That figure is not the letter's invention; it matches the kind of FAO-style sectoral estimate discussed above in connection with the IPCC and FAO assessments, and it is fair to attribute it as a genuinely mainstream scientific estimate rather than an activist exaggeration. What is the letter's own move, and should be read as such, is the further step from that evidence to a legal conclusion: combining the emissions and land-use evidence with the prohibition of idha' (animal suffering) and la darar (serious harm), the letter argues that meat, dairy and eggs are today haram. That conclusion is a minority advocacy position with no institutional standing — no major Sunni or Shia authority has ruled this way, and the mainstream position across both traditions remains permissibility. The descriptive evidence about deforestation, water and emissions can be taken seriously on its own scientific merits without adopting the letter's jurisprudential leap from that evidence to a change in ritual law, and the sections above and below on this page are an attempt to hold that distinction clearly.

Mizan: the measure in all things

A third concept, mizan — balance, measure, scale — appears in a passage that many contemporary Muslim environmental writers treat as close to a cosmological statement of ecological limits:

The immediate context of Surat ar-Rahman moves between cosmic order (the sun and moon "by precise calculation") and commercial honesty (weighing fairly in trade), and this dual register is precisely the point: mizan is simultaneously the physical order that sustains a habitable earth and the ethical order that should govern human dealings within it. Transgressing the balance — tughyan fi'l-mizan — is named as the vice to avoid. A climate system pushed past thresholds of stability by greenhouse gas accumulation, a soil system exhausted past its regenerative capacity, a fishery collapsed by overextraction: these can each be described, without straining the language, as instances of a balance transgressed. The 2021 Al-Mizan covenant, discussed further below, takes this verse as its organising image precisely because it refuses to separate cosmic order from moral conduct.

Hima and haram: classical conservation law

It is sometimes assumed that conservation law is a modern, secular invention that Muslim societies must retrofit their tradition to accommodate. The history is more interesting than that. Pre-Islamic Arabia already had a practice called hima — land set aside, typically by a powerful chief, restricting grazing or use for the benefit of that chief's own herds. The Prophet ﷺ did not abolish the institution; he reformed it, converting hima from a tool of private privilege into an instrument of public and religious welfare. Several hima zones are recorded as having been established or endorsed in the Prophetic period and by the early caliphs for purposes including the protection of grazing land, water catchments, and — significantly — wildlife and forest cover, administered for the common good rather than an individual's herds.

Alongside hima sits the haram, the sanctuary zone around Makkah and Madinah within which hunting, the felling of trees and other forms of environmental disturbance are legally restricted. The Prophet ﷺ is reported to have declared the area around Madinah a haram in terms that jurists later treated as establishing enforceable protections for its trees and wildlife — an area functioning, in effect, as a protected nature reserve underwritten by religious law rather than by a modern state conservation agency. Islamic legal scholars working on environmental law, notably Othman Llewellyn, have argued that hima and haram together constitute one of the world's oldest continuously documented systems of protected-area law, predating comparable European institutions by centuries. Several Muslim-majority countries and environmental NGOs, including IFEES, have drawn on this history explicitly in reviving hima-style community conservation schemes in the twentieth and twenty-first centuries, treating it not as a historical curiosity but as a living resource for contemporary environmental law.

The hadith of the sapling

Among the most frequently cited hadith in Muslim environmental writing describes an act of planting undertaken with no expectation of personal benefit at all:

The hadith is transmitted with some variation across collections and its precise chain has been discussed by hadith specialists, but its content is widely accepted and frequently quoted by scholars as an authentic expression of Prophetic teaching, regardless of small variations in wording. Its logic is deliberately extreme: even at the absolute limit of futility — the end of the world itself, after which no harvest, no shade, no benefit to any living creature could possibly follow — the instruction is still to plant. The purpose is not agricultural return. It is to habituate the believer to generative, life-affirming action as a disposition rather than a transaction, an ethic that sits close to, but is distinct from, later environmentalist arguments about intergenerational justice: plant not because you will benefit, but because planting is what a steward does.

The 2015 Islamic Declaration and Al-Mizan

These scriptural and legal resources are not merely of antiquarian interest; they have been mobilised directly in contemporary Muslim engagement with climate policy. In August 2015, ahead of the Paris climate negotiations, a symposium of Muslim scholars, scientists and environmental organisations meeting in Istanbul issued the Islamic Declaration on Global Climate Change. The declaration draws explicitly on khilafa, amana, mizan and the Qur'anic prohibition of fasad, and calls on well-off nations and oil-producing states in particular to lead in phasing down emissions, on businesses to shift away from a "profit-oriented economy" that disregards ecological limits, and on Muslims individually to reduce consumption and recognise ecological damage as a moral and religious failing rather than merely a technical or political problem. It was endorsed by numerous religious authorities across the Muslim world and remains a touchstone reference in Islamic environmental discourse.

More recently, the Al-Mizan covenant, published in 2021 through a collaboration including the Cambridge Institute for Sustainability Leadership and the Muslim Council of Elders, extends this project, taking the image of the mizan from Surat ar-Rahman as its central organising metaphor and framing the climate and biodiversity crises as a crisis of transgressed balance requiring both personal and collective response. What both documents share is a refusal to treat climate change as a purely secular-technocratic matter that religion might comment on from the outside; they insist it is continuous with core Islamic categories of trust, balance and accountability before God.

Where food fits in the climate account

Having set out the theological vocabulary, it is worth being precise about where food and agriculture actually sit in the climate picture, because loose claims are common in both directions. The Intergovernmental Panel on Climate Change's 2019 Special Report on Climate Change and Land found that the global food system — including agriculture, forestry and associated land-use change — contributes a substantial share of total anthropogenic greenhouse gas emissions, and that agriculture and land-use change together are among the largest drivers of deforestation, particularly in tropical regions where forest is cleared for cropland and pasture. The UN Food and Agriculture Organization's earlier sectoral assessment of livestock specifically found that livestock supply chains account for a significant share of human-caused greenhouse gas emissions worldwide, arising from a combination of enteric fermentation (digestive methane from ruminant animals), manure management, feed production and land-use change associated with pasture and feed cropland. These are documented findings from major scientific bodies, not activist estimates, and any serious Islamic environmental argument about food has to engage with them rather than dismiss them as ideologically motivated.

At the same time, precision matters. Figures for the food system's total emissions share vary between studies depending on methodology, time period and what is counted (direct emissions only, or the full supply chain including land-use change); readers should treat any single headline percentage as an estimate from a particular study rather than a fixed, universally agreed fact. What is not seriously contested among researchers is the general shape of the finding: animal-based foods, and ruminant meat and dairy in particular, tend to require substantially more land and generate substantially more greenhouse gas emissions per unit of protein or calorie produced than most plant-based staples, even though the exact multiples differ across studies and farming systems.

Ruminants, feed and land

Three distinct mechanisms are usually bundled together under "livestock emissions," and separating them clarifies where genuine debate lies. First, enteric fermentation: cattle, sheep, goats and other ruminants digest fibrous plant matter through microbial fermentation in a specialised stomach chamber, a process that produces methane as a by-product, which the animal then releases largely through belching. Methane is a far more potent greenhouse gas than carbon dioxide over short timeframes, though it also breaks down in the atmosphere more quickly, a fact that features heavily in technical debates about how best to compare it with CO2 in climate accounting. Second, feed: a considerable share of the world's arable land and grain harvest is devoted not to human food directly but to growing feed crops for livestock, and converting plant calories into animal calories involves an intrinsic energy loss — animals use much of what they eat for their own metabolism, movement and body maintenance rather than converting it all into edible tissue or milk. Third, land-use change: expansion of pasture and feed-crop cultivation, especially soy grown for animal feed, has been a documented driver of deforestation in parts of South America, removing carbon-storing forest cover and its associated biodiversity.

None of this licenses the claim that livestock farming as such is simply incompatible with Islamic environmental ethics — the picture is considerably more textured than that, and the next section takes that texture seriously.

Personal duty or structural distraction?

Given this evidence, an intra-Muslim (and indeed a broader environmental) debate follows immediately: does the amana obligate individual Muslims to change what they eat, or does emphasis on personal diet function as a distraction from the political and corporate decisions that actually determine emissions trajectories — fossil fuel subsidies, industrial-scale deforestation permits, agricultural policy, the subsidised overproduction of feed grain? This is not a manufactured disagreement; it runs through environmental ethics generally, and Muslim writers divide on it in ways that map onto, but are not identical with, the wider debate.

These positions are not, in practice, mutually exclusive, and most serious Muslim environmental writers hold some blend of both: that personal conduct matters religiously in its own right regardless of its measurable planetary effect, and that it is not a substitute for structural change. What divides people more sharply is emphasis — how much weight a khutbah, a curriculum or an individual conscience should place on the plate relative to the ballot box, the boardroom and the subsidy line.

The pastoralist counterpoint

A further complication, often underweighted in Western-centred environmental writing, deserves direct treatment: a great many Muslim communities are pastoralist or agro-pastoralist, their livelihoods and food security built around livestock in ways that long predate industrial feedlot agriculture and bear little resemblance to it. Fulani, Somali, Kazakh, Baloch and many other Muslim pastoralist communities across the Sahel, the Horn of Africa, Central Asia and elsewhere depend on cattle, camels, sheep and goats grazed on land often unsuitable for arable cropping, in systems that have operated for centuries and are frequently far less input-intensive, and in some analyses more compatible with dryland ecology, than the industrial grain-fed feedlot model that dominates the emissions literature from wealthy countries. Blanket rhetoric that treats "eating animals" as a uniform global sin, without distinguishing a feedlot system dependent on cleared Amazonian soy from a Sahelian herder's transhumant flock, risks a real injustice: it can stigmatise precisely the communities with the least responsibility for the emissions the argument is trying to address, while the largest agribusiness emitters continue largely unnamed.

This is not a rhetorical trump card that ends the environmental argument — pastoralist livestock still has ecological footprints worth taking seriously, including in cases of overgrazing or land degradation, and the hima institution discussed earlier developed in no small part precisely to manage exactly these pressures within pastoralist societies. But intellectual honesty requires holding two things together: the aggregate, global evidence on industrial livestock's land and emissions footprint is real, and the moral conclusions drawn from it must be calibrated to the system actually being discussed rather than applied indiscriminately to every context in which an animal is herded, milked or eaten.

What stewardship might ask of an individual

None of the theology surveyed here settles, by itself, what any individual Muslim should eat — that remains, as elsewhere on this site, a matter of contested interpretation rather than a fixed ruling. What the khilafa-amana-mizan vocabulary does supply is a register in which the question can be asked seriously: not "is this trendy or is this backward-looking," but "does this practice honour or corrode a trust I did not create and do not own outright." For some Muslims that register will lead towards eating less meat, or sourcing it more carefully, as one small and partial expression of amana; for others it will lead towards defending and supporting pastoralist and smallholder systems against the same industrial logic that drives deforestation elsewhere; for most it will mean holding both concerns simultaneously, resisting the temptation to resolve a genuinely difficult ecological and ethical picture into a single slogan. The sapling hadith remains, perhaps, the most honest note to end on: plant, expect no return, and do not let the scale of the crisis be the reason you refuse to begin.
