Decarbonising the pulp and paper sector accelerates as technology, policy, and investment align

The pulp and paper sector faces a narrowing window to decarbonise at scale. With energy intensity and process heat at the core of its emissions profile, companies must reconfigure operations while safeguarding throughput and product quality. Technology suppliers claim they can deliver that balance, but translating capability into sector-wide impact will require concrete targets, verified measurement and aligned investment.

According to Valmet, its Climate Programme launched in 2021 sets out such targets across operations, supply chains and customer technologies, aiming to reduce the company’s own CO₂ emissions by 80% and cut supply‑chain emissions by 20% by 2030 without relying on offsets. The firm also reports that, by the end of 2023, it had reached full carbon‑neutral electricity purchases in Finland and Sweden and achieved substantial reductions in energy‑related emissions through measures such as solar installations and HVAC optimisation. Valmet’s progress underlines how supplier actions can both lower their own footprint and enable customers to decarbonise production.

For industrial customers, the practical requirement is a clear roadmap that converts ambition into measurable steps. That means setting milestones for emissions reductions in on‑site operations, procurement of low‑carbon energy and the technologies embedded in process equipment. It also entails deploying continuous monitoring systems able to produce verifiable data for investors, customers and sustainability ratings. Industry data shows greater transparency is increasingly a precondition for market access and finance; firms that can demonstrate credible measurement are better positioned for inclusion in indices and disclosure frameworks.

Real projects are beginning to illustrate the pathway. Valmet points to recent plant modernisation work in Latin America where provision of high‑efficiency recovery boilers and biomass boilers formed part of a package intended to lower fossil fuel dependence and improve overall carbon performance. Such combinations of electrification, fuel switching to bioenergy and improved heat recovery are the core levers for sites seeking deep cuts in scope 1 and scope 2 emissions. However, implementation is complex: electrifying thermal processes, sourcing truly carbon‑neutral electricity and integrating new equipment into legacy plants all require engineering design choices and capital allocation that vary by geography and regulatory regime.

Partnerships are emerging to address the harder technical problems. According to a memorandum announced by Valmet and Saipem, the two firms will explore integrated solutions combining Saipem’s CO₂ management technologies with Valmet’s heat recovery and flue‑gas systems. Industry participants say such collaboration is critical for “hard‑to‑abate” process emissions where capture, reuse and efficient heat management must be designed together to be economically viable.

Barriers remain material. Upfront capital for electrification and capture technologies can be large, and divergent national regulations and grid decarbonisation timetables complicate the arithmetic for multinational operators. Supplier claims about carbon‑neutral product routes depend on customer choices as well; Valmet, for example, offers routes to carbon‑neutral pulp and paper production provided customers adopt bioenergy or certified carbon‑neutral electricity. That conditionality illustrates the need for end‑to‑end alignment across value chains rather than isolated vendor solutions.

To accelerate uptake, the sector will need coordinated policy signals, targeted finance and lifecycle thinking from procurement through to product use. Investment in engineering expertise to optimise plant design can lower total cost of ownership and make staged technology rollouts more affordable. Meanwhile, robust, auditable emissions monitoring will be necessary to convert operational changes into recognised improvements under frameworks such as CDP and sustainability indices. Valmet’s own CDP “A” rating, awarded for disclosure and climate governance, demonstrates the market recognition that comes with transparent reporting.

Ultimately, success will be measured by speed and scale. The next five years are widely regarded within the industry as decisive for locking in pathways compatible with a 1.5°C outcome; companies that move early to electrify processes where feasible, substitute fossil fuels with sustainable alternatives and invest in integrated CO₂ management stand to retain competitiveness. Achieving net‑zero across the sector is not solely a technological challenge but a commercial one: buyers, financiers and regulators are shifting the performance baseline, and firms that fail to align with the emerging standard risk losing market access.

The tools to begin that transition exist today; the remaining tasks are aligning incentives, mobilising capital and delivering verifiable implementation at plant level. For an industry long identified as energy‑intensive, decarbonisation is reshaping what constitutes operational excellence. The question now is whether incumbents move from statements to systemic action at the scale and pace required.
