The concept of a "carbon footprint" helps measure and illustrate the environmental impact of a product, business, industry or individual. The simple definition is the total amount of greenhouse gases produced to support a given activity — usually expressed in tons of carbon dioxide equivalent (CO2e).
When looking at the carbon footprint of paper-based products, we consider the emissions generated, sequestered and avoided throughout its lifecycle—this includes the emissions associated with the raw wood and continues through the product’s life cycle, ending with the emissions associated with the product's reuse, recovery or disposal.
Reducing Our Impact
At International Paper, we recognize that our products — like all products and all businesses — have a carbon footprint. We also recognize that there are measurable actions we can take to improve it. One way we can do this is through promoting circularity in our value chain. This starts with our suppliers practicing responsible forest stewardship, which contributes to the removal of CO2 from the atmosphere. We also continuously work to reduce greenhouse gas emissions during manufacturing and increasing the recovery and recycling of our paper-based products.
For paper-based products, there are three major factors that affect the carbon footprint: carbon sequestration in forests, carbon emissions generated during manufacturing and processing and avoided emissions associated with biomass fuel usage. Throughout the life of a product, each of these carbon impacts plays a key role in the overall carbon footprint.
The fiber used to make our products is sourced from responsibly managed forests, which provide carbon benefits through carbon sequestration. Forests store carbon dioxide while providing wood fiber for paper-based products. Our use of wood fiber provides landowners an incentive to keep land forested where trees can bind carbon, and responsible forest management helps ensure that new trees are grown to replace those removed during harvest.1 Productive forests that are managed to make products that store carbon can have greater long-term carbon benefits than forests left unmanaged.2
At International Paper, our products are made from a renewable raw material procured from suppliers who practice responsible forest stewardship — this promotes the stewardship of forests so that they can continue to sequester carbon long into the future.
Carbon Emissions Generated
The manufacturing of fiber-based products generates direct (Scope 1) and indirect (Scope 2 and Scope 3) emissions across the value chain. Direct (Scope 1) emissions are any emissions that are generated directly from operating our facilities and manufacturing our products. These include emissions generated from the use of fossil fuels to operate equipment or from generating power in our manufacturing process. Indirect emissions result from purchased electricity (Scope 2) as well as emissions that occur throughout the remainder of a product's life cycle (Scope 3), such as during product transportation and distribution.
Through continuous improvements in operations, equipment energy efficiency and fuel diversity, we work to reduce both our Scope 1 and 2 emissions. We have surpassed our goal of reducing greenhouse gas emissions by 20 percent by the end of 2020 and we’re working on defining our next generation goal to further improve our environmental footprint.
Nearly 75% of the energy used in our mills is generated from biomass residuals rather than fossil fuels
Our products are manufactured using nearly 75% renewable biomass residuals.
While manufacturing paper-based products consumes energy, our use of biomass as an energy source significantly lowers our net carbon emissions. We employ two types of residual biomass: manufacturing residuals and forest-derived residual biomass that would otherwise be waste. Forest-derived biomass includes things like the limbs and branches left on the forest floor, while manufacturing residuals are the “leftovers” from product manufacturing such as bark.
The U.S. Environmental Protection Agency (EPA) considers biomass from managed forests as carbon neutral when used for energy production at stationary sources3. This provides greenhouse gas benefits by avoiding the emission of about 181 million metric tons annually of CO2 equivalent4. This is equal to the emissions of about 35 million cars5.

Our Products Are Recyclable And Have Always Been Circular
Because paper-based products are made from natural materials, they can be recycled at high rates. This is critical because when paper decomposes in landfills, it releases methane — a powerful greenhouse gas — but recycling helps cut down on these emissions. Our process is circular by nature – from the sourcing and replenishment of our primary renewable raw material, to our use and beneficial reuse of byproducts in the manufacturing process and finally the use, recovery and reuse of our products. This circularity is core to our industry and our existence.6
You can play a role in the carbon footprint of paper-based products. The more paper and cardboard get recycled the lower its carbon footprint. Please remember to always recycle.
There are other often overlooked carbon benefits of responsibly managed forests. When forests are responsibly managed, the potential for wildfire is reduced, thus limiting large carbon releases.
While forests naturally sequester carbon, they remain under threat from deforestation from competing land uses such as agriculture and development. The pulp and paper industry provides economic incentives for keeping land in forests, which when managed sustainably ensure that they can continue to serve as a carbon sink. Conversions of forests to other uses almost always results in large releases of carbon.

Research from The Nature Conservancy published in 2017 indicates that forests offer the single largest "natural climate solution".
In 2018, International Paper and The Nature Conservancy partnered to advance "natural climate solutions" — the conservation, restoration and improved forest management techniques that increase carbon storage and avoid greenhouse gas emissions in forest landscapes.7 One natural climate solution is Reduced-Impact Logging for Carbon (RIL-C), a set of practices pioneered by The Nature Conservancy that balance the economic needs of forest-based communities and businesses with environmental goals, especially climate mitigation.
Forests can store more carbon when responsibly managed, making forest stewardship key to mitigating climate change while supporting economic and social needs for paper-based products. As the demand for paper-based products increases, so does the need for responsibly managed forests, and that means a better chance at mitigating climate change. See The Future of Forests for more.
Understanding the carbon footprint of our products starts with our suppliers, whose commitment to responsible forest stewardship increases the carbon sequestration potential of the forest. Air emissions and energy usage during manufacturing plays a key role in improving our products' impact on the climate. And finally, the recovery and recycling of our paper-based products completes the cycle, diverting carbon from landfills. We hope you will join us in reducing the footprint of paper-based products by recycling them.
