Gren’s ESG commitments
Gren provides district heating, cooling and industrial energy solutions across the Baltics and the UK, built primarily on biomass and other locally sourced, waste-derived fuels.
Our ESG priorities are structured around the following themes:
Environment
Reducing the emissions and environmental footprint of our own operations and our customers’ operations while sourcing our fuel responsibly from certified sources*.
Social responsibility
Protecting the safety and wellbeing of our people, and engaging with local communities where we operate.
Governance
We apply ESG criteria in our governance, risk management and investment processes. We report voluntarily based on newest reporting standards for added transparency towards our owner and stakeholders.

We publish our targets, methodology and progress annually in our ESG report, and we are working to align our disclosures with the Corporate Sustainability Reporting Directive (CSRD) and the European Sustainability Reporting Standards (ESRS).
Below, you can access our ESG reports for the current and previous years, along with the underlying data and methodology behind each target. Our Code of Conduct sets out the ethical standards we apply across our business, and our Supplier Code of Conduct describes the sustainability requirements we expect from partners across our value chain. Together, these documents give a full account of how our sustainability commitments translate into business practice.
Our Code of Conduct
describes the basic ethical standards that we always must respect. It reflects our values and our beliefs that conducting business in an ethical and transparent manner is the only way to work and these commonly agreed principles guide us on making the right decisions. Following the high ethical standards gives us license to operate and supports the implementation of our growth strategy and achieving business goals. We want to be a reliable and trusted partner for our customers, communities and business partners.
