Climate Change
Because our mines run primarily on renewable energy, our Scope 2 GHG emissions are low relative to our peers. Over time, we expect further reductions in GHG intensity as we continue to improve operational efficiencies. In 2025, Hecla’s responsible mining practices once again achieved an intensity ratio of metric tonnes of GHG emissions per silver ounce produced of 0.007, one of the lowest in the industry.
We have set specific goals related to climate action, including increasing our use of renewable energy and improving our climate change disclosure and risk response. Building on our existing progress toward these goals, Hecla is in the process of identifying achievable goals for GHG emissions that take into account our evolving business strategy and changing operational footprint.
Strategy and Risk Management:
Alongside Hecla’s work to minimize operational emissions and provide essential materials for the low-carbon transition, we are also focused on building our company’s resilience by adapting to and mitigating risks. Climate related projections are a part of the risk management and planning process for each Hecla mining operation.

Greenhouse Gas (GHG) Protocol
To determine Hecla’s Scope 1 and Scope 2 Carbon Dioxide Equivalent Emissions (CO2e), a third party consultant utilizes U.S. Environmental Protection Agency (EPA) reporting standards, protocols, methodologies, and other related guidance.
The GHG guidance is based on The Greenhouse Gas Protocol: A Corporate Accounting and Reporting Standard (GHG Protocol) developed by the World Resources Institute (WRI) and the World Business Council for Sustainable Development (WBCSD).
Emissions-Based Maintenance Program
Hecla’s emissions and energy consumption reductions were accomplished through operating efficiencies that lower the use of electricity, diesel fuel, gasoline, natural gas, and propane. Among our efficiency tools is an Emissions-Based Maintenance (EBM) program that uses emissions data to determine whether equipment is running most efficiently or requires maintenance. This program has been fully implemented at Greens Creek and is being introduced at other sites as well.
Alternative Energy Sources
One of Hecla’s largest sources of electricity is renewable hydropower, and we use as much hydroelectricity as our power suppliers can provide. Currently, at our sites in production:
- At Greens Creek, Hecla has an agreement with the local utility to purchase surplus power from the grid when it is available. This surplus power is 100% renewable hydropower, and in 2025, lower-than-average precipitation reduced hydropower availability, resulting in 62% of the mine’s electricity being purchased from the grid. Since 2009, this arrangement has allowed Greens Creek to avoid consuming more than 90 million gallons of diesel fuel, and because the mine draws from the same grid that serves local residents, its participation helps reduce energy costs for Juneau customers.
- The energy provider at our Lucky Friday location uses a mix of both hydropower and natural gas, with 60% of electricity sourced being renewable; and
- 82% of Keno Hill’s power comes from renewable sources such as hydropower.
