Efficiency

Developing a Path to Carbon Neutrality

Reduction of greenhouse gas emissions has long been a focus of Domtar. The company’s pulp and paper mills have achieved a 27% reduction in total direct emissions and indirect emissions from purchased energy since 2010, surpassing our goal of a 15% reduction by the end of 2020. These reductions were largely achieved through fuel switching to carbon-neutral and lower carbon-intensive fuels (i.e., coal to natural gas), energy and operational efficiency projects, a greener electrical grid, and in 2020, lower production output. While these efforts have positioned Domtar well for a lower-carbon economy, we realize more needs to be done.

Changes will be required in both the short and long term to achieve international climate goals that an overwhelming majority of scientists and governments agree need to be met to minimize the worst effects of climate change. Domtar is committed to being at the table and doing our part to tackle this global issue – one that will require transformative changes to social, economic and environmental systems. We expect these changes will present us with both opportunities and challenges.

To that end, Domtar has begun evaluating pathways and developing plans to understand what “net zero” by 2050 would mean for our business. This requires a holistic strategy that considers what products we make, how we manufacture them, our supply chain, our governance and financial systems, research and development for new technologies, along with cooperation with policymakers and governments for sustainable climate mitigation frameworks.

Since 1990, Domtar’s mills have reduced total direct greenhouse gas emissions from fuels used in our manufacturing processes by 55%.

Our work to lower our carbon footprint over the past few decades has also led to significant reductions in our emissions to air of nitrogen oxides, sulfur dioxide, total reduced sulfur and particulate matter. As we execute plans for a lower carbon future, our energy efficiency initiatives and changing energy sources are expected to lead to further reductions in air emissions, albeit at a slower pace.
