The Climate Leadership Coalition (CLC), which develops business-driven solutions to address climate change, has accepted two new organizational members: Outokumpu Oyj and Zero Terrain. These companies further strengthen CLC’s position as the largest non-profit climate business network in Europe by membership and expand the CLC’s network to the Baltics; Zero Terrain has its Headquarters in Tallinn, Estonia. Outokumpu brings strong industrial knowledge to the network, as the company is the global leader in sustainable stainless steel in Europe and the United States; annually, their products support customers in reducing their emissions by over 10 million tonnes.

CLC now has 99 organizational members.

“Steel accounts for 7-9% of global greenhouse gas emissions. At the same time, it plays a pivotal role in accelerating the green transition. From hydrogen to electric vehicles and clean energy, low-carbon economies rely on stainless steel. Outokumpu has been a pioneer in the circular economy in the industry – our product reduces customers’ emissions by 75% compared to the industry average – and with our spearhead innovation, Circle Green, even further up to 93%. We have ambitious climate targets aligned with 1.5 degrees, and we execute them with concrete initiatives – for example, by targeting to achieve carbon neutrality in our Kemi mine as the first mine in the world by 2025. Sustainability truly drives our business decisions, and we are excited to join CLC’s impactful network to drive the change in global regulation mitigating climate change,” says Heikki Malinen, President, and CEO of Outokumpu Oyj.

Zero Terrain is an Estonian company initiated in 2009 and developing its first pumped-hydro energy storage (PHS) in Paldiski, Estonia. Zero Terrain’s novel PHS technology is the next-generation solution in the field, eliminating the need for altitude difference in terrain as the plant can be built on flat land; traditional pumped-hydro storages can only be built in mountainous areas.

“Zero Terrain has introduced a new solution to the market: pumped hydro energy storage technology, which produces affordable renewable energy with minimal ecological footprint and solid supply security. In addition, Zero Terrain’s pumped-hydro storages increase the profitability of wind and solar energy producers and help operators maintain power system stability and minimize system costs. We are honored to join CLC’s wide network of climate leaders, and we will actively contribute to fostering collaborations driven by the network,” says Peep Siitam, Founder, and CEO of Zero Terrain.

The CLC Board has also accepted one new individual member: Hannu Keinänen, who is the former CEO of Ensto. The number of personal members of CLC is now 66.

“Our growing membership base and network of partners enhance CLC’s potential to support EU and global decision-makers in work to mitigate climate change and transition away from fossil solutions. We look forward to working together with Outokumpu Oyj, a leader in their industry, and Zero Terrain, which has innovated a new solution for the energy sector. We also warmly welcome Mr. Hannu Keinänen, whose expertise will strengthen the global network of the CLC Advisory Board,” says Sari Baldauf, Chair of the CLC Board.

CLC members employ over 1,000,000 people globally and represent over 70% of the market cap of the OMX Nasdaq Helsinki stock exchange. CLC’s members believe that transitioning society towards a sustainable economy and consumption is not only possible but also economically viable.
