Key facts about paper’s impact on greenhouse gas emissions and climate change

A recent consumer survey commissioned by Two Sides showed a disconnect between consumer perceptions and the facts about the industry’s impact on global GHG emissions.  The survey showed that 29% of Americans believe that paper production is a major contributor to global GHG emissions.  However, the U.S. pulp and paper sector is one of the lowest emitters of GHG emissions among major U.S. industrial sectors at 1.2% of total U.S. industrial GHG emissions.

One of the reasons for the relatively low GHG emissions of the forest products industry is its use of renewable fuels.  For example, bioenergy use by paper and wood product mills in the U.S. prevents the emission of 181 million metric tons of CO2 equivalents, by merely using waste wood from manufacturing operations. This practice produces the same reduction in GHG emissions as removing about 35 million cars from the road.

In Canada, the forest products industry has made great strides to reduce GHG emissions in production, by cutting the use of coal and cutting oil use by over 90% since the year 2000. In fact, 57% of the industry’s energy use in 2015 was generated by bioenergy.

Forest products also play a key role in global carbon sequestration (absorption) and the mitigation of GHG emissions. As they grow, trees remove CO2 from the atmosphere and they release oxygen, allowing us to breathe and sustain life on the planet.  By managing our forests sustainably for the long-term we can ensure that they continue to provide economic, social and environmental benefits, including climate change mitigation.  For example, forests in Canada removed 150-160 million tonnes of CO2e from the atmosphere annually (between 2005 and 2016).

A recent scientific paper has shown that the regeneration of forests through sustainable practices in the paper industry may lead to more carbon sequestration. Globally, younger forests (those growing for less than 140 years) store 1.17-1.66 billion metric tons of carbon per year while old-growth forests sequester 950 million-1.11 billion metric tons.

Forest products like paper continue storing carbon even as a finished product and beyond their life in the forest. It is only if paper is landfilled, burned or left to decay that it begins to release CO2 again.  In 2016, forests and wood products in the U.S. captured and stored roughly 10% of all carbon dioxide equivalents emitted by the U.S.

But then why do people assume that going digital is greener?  The “hidden” life cycle of our massive electronic infra-structure may be one reason.  The fact is that many of us don’t think much about what goes into the manufacture and operation of our computers, smartphones, the energy needed to operate server farms, store massive amounts of digital information, and send emails.  It is significant, but largely out of sight and out of mind.
