The reason "tonnes of CO₂" became the universal sustainability currency is that it is cleanly globally fungible. A tonne reduced in Lahore counts the same as a tonne reduced in Los Angeles. The chemistry doesn't care about the geography.
The problem is that people care about geography. In emerging economies, what matters most to actual lives is often only weakly correlated with the carbon line on a spreadsheet. A water-stressed industrial cluster in Sindh, an air-quality crisis in rural Bihar, a women's livelihood collapse in Dhaka's recycling economy, none of it shows up in a Scope 1+2+3 disclosure. And because it doesn't show up, capital doesn't flow toward solving it. The result is a sustainability industry that is busy and well-funded but increasingly disconnected from the welfare gains it claims to deliver.
Definition What is a Scope 1+2+3 disclosure? +
The GHG Protocol divides corporate emissions into three scopes. Scope 1 covers direct emissions from owned or controlled operations (e.g. factory furnaces, owned vehicles). Scope 2 covers indirect emissions from purchased electricity, heat, or steam. Scope 3 covers all other indirect emissions across the full value chain, from raw material extraction to product end-of-life. Scope 3 typically represents 70–90% of a company's total footprint but is the hardest to measure and verify.
Five missing metrics that should carry as much weight as carbon in any emerging-market sustainability assessment.
1. Water stress avoided
Pakistan, India and Bangladesh sit in basins where freshwater, not energy, is the binding constraint. A textile dyer in Faisalabad that switches to closed-loop recycling saves 10,000–50,000 m³ per year in a city where the aquifer is dropping by a metre annually. The CO₂ savings from that intervention may be modest; the water saved is life-altering for the catchment. Yet there is no globally tradeable water credit, and Western procurement teams rarely ask for water intensity data when they ask for emissions data.
2. Air quality externalities
The Indo-Gangetic plain has the worst sustained air pollution on earth. Estimated annual mortality from PM₂.₅ exposure in India alone is ~1.7 million people, roughly ten times the global annual death toll currently attributed directly to climate change. A cookstove or brick-kiln upgrade that cuts local particulates by 70% is doing more for human welfare than its modest CO₂ savings suggest. The post-2023 carbon-integrity reset tightened the climate claims, but in the process it devalued projects whose real impact was airshed-level public health.
Definition What is PM₂.₅? +
PM₂.₅ refers to particulate matter with a diameter of 2.5 micrometres or less, fine enough to penetrate deep into the lungs and enter the bloodstream. It is emitted by combustion sources including vehicles, brick kilns, crop burning, and coal-fired power plants. Long-term exposure is linked to respiratory disease, cardiovascular disease, and premature death. The WHO guideline is an annual mean of 5 µg/m³; large parts of South Asia routinely exceed 50–100 µg/m³.
3. Female labour participation
Renewable build-out, EV scale-up, climate-resilient agriculture, each of these can either entrench or transform the gender composition of the workforce. South Asian female labour force participation sits at 24% in India, 21% in Pakistan, 38% in Bangladesh. A 100 MW solar park that hires 500 male technicians and a 100 MW solar park that builds a women-led O&M training pipeline have identical kWh but radically different developmental trajectories. Who, not just what.
4. Employment resilience and just transition
Every climate win has a labour shadow. Coal phase-down in Jharkhand, captive thermal closures in Punjab, fishing-economy disruption from blue carbon enclosures. The Just Transition Framework exists; it is rarely priced into project assessment. A decarbonisation pathway that displaces 5,000 workers without a retraining and absorption plan is a climate success and a development failure simultaneously. Insisting on funded reskilling, social protection bridges and alternative livelihood support should be a non-negotiable line item in any emerging-market climate engagement.
Definition What is the Just Transition Framework? +
The Just Transition Framework, developed through ILO guidelines and endorsed in the Paris Agreement preamble, holds that the shift to a low-carbon economy must protect and create decent work for affected communities. It covers social protection, skills development, economic diversification, and community consultation. In practice, it means that climate projects displacing fossil-fuel workers or subsistence communities must fund alternative livelihoods, not just offset carbon.
5. Informal sector livelihood shifts
India's Extended Producer Responsibility (EPR) rules for plastic packaging are reshaping a sector that ~1.5 million informal waste pickers depend on. Done well, EPR formalises and dignifies their work. Done badly, it bankrupts them in favour of large-format material recovery facility operators. The same logic applies to e-waste, scrap metal and used textiles. A circular-economy intervention that delivers strong recycling-rate metrics while collapsing the informal income base has not improved sustainability, it has merely transferred its costs onto people without lobbying power.
Definition What is EPR (Extended Producer Responsibility)? +
Extended Producer Responsibility (EPR) is a policy instrument that makes manufacturers financially and operationally responsible for the end-of-life management of their products. In India, EPR obligations for plastic packaging, e-waste, and batteries require producers to ensure a defined percentage of their material is collected and recycled each year, either through their own systems or by purchasing credits from certified recyclers. When poorly designed, EPR systems displace informal recyclers who previously performed that function.
What this means in practice
Composite scoring. Locally weighted. Honestly disclosed.
In emerging-market advisory work, we now insist that any project assessment carry, alongside its carbon line, a water intensity figure, an airshed health impact estimate, a workforce gender breakdown, a just transition plan, and an informal-economy impact note. Five additional numbers. Each specific. Each disclosed.
The single tonne is not wrong. It is just not enough.
Ennacle works with project developers, corporates and investors across South Asia to build sustainability assessments that price what actually matters in context, not just what travels well in a global spreadsheet.
