Packaging is everywhere — from the sachet that carries instant coffee to the corrugated box that ships a laptop across continents. Its omnipresence makes it an invisible part of daily life, yet the environmental cost is immense.
The packaging sector is responsible for an estimated 1.8 billion tonnes of CO₂-equivalent emissions every year. In the context of the world’s 53 billion tonnes of total greenhouse gas emissions (2023), packaging alone accounts for roughly 3.4% of the global footprint.
That is not a marginal slice; it is a major lever in the race to net zero.
Where the emissions come from
Most of packaging’s climate burden begins at the material stage. Producing virgin plastics from fossil feedstocks, extracting pulp for paper, or processing metals and glass all consume vast amounts of energy and resources.
The converting stage — printing, laminating, coating — adds another layer of emissions, while e-commerce growth has driven packaging-intensive logistics worldwide. Finally, end-of-life mismanagement — landfilling, incineration, and the failure to recycle effectively — perpetuates both emissions and resource loss.
Plastic is the most acute problem: if current production trends continue, plastics alone could consume a dangerously large share of the remaining carbon budget by mid-century.
What studies show about climate savings
The good news is that the packaging sector has some of the most practical and near-term solutions available. According to the Ellen MacArthur Foundation, adopting a circular economy model for plastics — cutting problematic items, scaling reuse, and designing for recycling — could reduce emissions by about 25% versus current projections by 2040.
Reuse systems show even greater promise. Independent analyses report that reusable packaging in categories like beverages, retail containers, and delivery parcels can slash production by up to 90% and reduce emissions by as much as 80%.
Scenario analysis — three possible futures
Based on the 1.8 Gt baseline, the packaging sector could unlock significant climate dividends:
A conservative pathway, relying on better recyclability, lightweighting, and incremental improvements, would cut emissions by about 30%, or 0.54 Gt CO₂e annually. That equates to just over 1% of global emissions.
An ambitious transition, driven by material substitution, high recycled content, and systemic redesign, could achieve a 60% cut, avoiding 1.08 Gt CO₂e per year, or roughly 2% of the global footprint.
A transformative shift — widespread reuse, circular value chains, and minimal virgin feedstock — could reduce emissions by 80%, saving 1.44 Gt CO₂e annually, about 2.7% of global emissions.
Put differently, if the packaging sector were to fully embrace net-zero transformation, it could deliver emissions cuts comparable to erasing the annual output of several industrialized nations.
Where the biggest gains lie
The bulk of these reductions will come from replacing virgin fossil plastics with recycled or biobased content, scaling reuse models that keep packaging in circulation, and ensuring end-of-life systems like recycling actually work at scale.
Logistics efficiencies — lightweighting and optimized palletization — add further savings. Renewable energy in converting plants will be essential. Yet substitution must be managed carefully: replacing plastics with heavier glass or metals without accounting for lifecycle emissions can, in some cases, worsen the climate impact.
The policy and business levers
Unlocking this transformation will require coordinated action. Mandatory recycled-content standards, caps on virgin plastic, and clear reuse targets could provide the regulatory backbone.
Investment in high-quality recycling infrastructure, deposit-return schemes, and incentives for refill systems would accelerate uptake. Extended producer responsibility (EPR) schemes can ensure that producers internalize the cost of waste.
Meanwhile, procurement policies — from governments and major retailers — can generate reliable demand for low-carbon packaging.
Why companies should act now
For businesses, going green in packaging is not only about compliance or brand reputation. There is a clear cost upside: circular material use reduces exposure to oil and resin price volatility.
Regulators are tightening rules worldwide, and companies that fail to adapt risk stranded assets. Consumers, too, are shifting. Surveys increasingly show that sustainable packaging is a purchase factor, particularly among younger demographics. Companies that invest early will be better positioned to capture this demand and avoid disruption.
Limits and caveats
Not all interventions are straightforward. Recycling rates for plastics remain stubbornly low, and in many countries, less than 10% of collected plastics are recycled into equivalent-quality materials. Reuse requires system-level investment in logistics and infrastructure, not just novel technology.
And while circularity in packaging could save over a gigaton of emissions, it cannot, by itself, solve the climate crisis — but it can meaningfully close the global emissions gap when paired with parallel action in energy, transport, and heavy industry.
Editorial takeaway
The packaging industry is not a minor polluter; it is a significant emitter with one of the clearest paths to rapid decarbonization.
If the sector commits to serious systemic change, it could cut between 0.5 and 1.5 Gt of CO₂e annually, shifting the global emissions trajectory by 1–3 percentage points. That is a measurable and critical contribution to the world’s 2030 climate targets.
The challenge for policymakers and corporate leaders is to stop treating packaging as a peripheral issue. Done right, packaging could move from being a climate liability to a replicable model of how industries can achieve net zero.
