Infinis is the largest generator of electricity from LFG in the UK, with a portfolio of 121 landfill sites and total installed capacity of over 300MW. LFG is produced by decomposing organic matter in landfill sites. If released into the atmosphere unchecked, LFG contributes to pollution and is a potent greenhouse gas. By extracting LFG from landfill sites, Infinis fulfils an essential role in helping landfill operators meet their environmental compliance obligations. By using the collected LFG to generate electricity, Infinis supplies distribution networks with a consistent source of baseload power.

Infinis is now a diversified, renewable and low carbon energy generation business. It is developing over 1GW of new low carbon energy projects, including solar energy parks. Its continued investment in renewable energy is helping the UK reduce its reliance on fossil fuels and supports the UK’s energy sector transition to net zero. It also reduces electricity costs for consumers. Infinis' broader sustainability strategy revolves around creating value for its stakeholders, through protecting health, wellbeing and safety, reducing carbon emissions, eliminating exploitative work and improving diversity and inclusion. In 2022 the UK National Audit Office identified its Annual Report as best practice in relation to the Stakeholder engagement reporting.
