Planet-Positive Impact
Mainstream is committed to delivering planet-positive impacts through our projects by working to achieve net zero emissions and biodiversity net gain.
We report our Scope 1, 2 and 3 emissions in accordance with the international GHG Protocol and will set science-based or equivalent standard targets to align our operations, investments, and supply-chain with Net Zero.
Published on April 24, 2023, our latest annual Sustainability Report showcases our efforts to implement the green energy transition while cutting emissions, protecting nature, and supporting local communities.
Reducing waste
We aim for zero waste to landfills through prevention, reduction, recycling, and reuse of materials throughout our value chain.
Reduce Emissions
Our large-scale renewable energy assets displace the demand for fossil fuels, reducing greenhouse gas emissions and accelerating the transition to a climate-safe future.
Protecting biodiversity
We are committed to protecting, preserving, and restoring the environment and biodiversity, with a goal of achieving biodiversity net gain.
Saving water
We will systematically adopt measures that avoid or reduce water usage so that our projects’ water consumption does not have significant adverse impacts on others.

Evolving actions to meet the challenge
Our latest Sustainability Report sets out our evolving approach to:
- Achieving net zero emissions
- TCFD implementation
- Land use and ecological sensitivity
- Water consumption and withdrawal in water-stressed areas
- Circularity and impact of solid waste disposal
All while building on our planet-positive company culture.
Mainstream’s mission to lead the global transition to renewable energy means we are fully committed to combating climate change.

Mangroves are an important carbon sink, storing significantly more than forests on land.
They are also a crucial habitat for many species and serve as an important addition to safeguarding livelihoods as the local communities add to their income by collecting crabs and shellfish in the area.
Together with the British Embassy in Vietnam and the Song Foundation’s Green Happiness Program, Mainstream launched a fundraising activity to support the planting of mangrove trees across 10ha of alluvial plains in Vietnam’s Soc Trang Province.
Expanding renewable energy whilst safeguarding the environment
In Chile, we’ve been working with ecological specialists from local universities to help protect rare bird species by:
- Deploying specially trained dogs to detect nesting grounds, which were then avoided when siting turbines and access roads.
- Using computer vision and sensor technology to monitor bird activity in the area, supporting environmentally friendly project planning.
- Recording data to further academic research on these protected bird species: the Gaviota Garuma (Grey Gull) and Golondrina de Mar (Wilson’s Storm Petrel).
- Collaborating with local universities to help educate workers on environmental management, fauna rescue and rehabilitation.
See how we’re using new methodologies to help protect these rare bird species in Chile.
Turbine recycling
As the wind energy industry continues to expand, so too does the volume of waste produced by the sector, in particular from wind turbine blades which are reaching the end of their life cycle or are being replaced by more efficient models.
Mainstream and researchers at the University of Strathclyde, together with other consortium members, are leading a GBP 2 million wind turbine blade recycling pilot in the UK.

Our commitment to protecting the environment in South Africa
The Allanridge Cluster was a solar development which consisted of 3 x 100MW solar projects situated in the Free State approximately 20km to Welkom.
The projects were identified as suitable solar sites during Greenfielding and a lidar station was installed to measure the resource.
However, during the Environment Impact Assessment (EIA) phase of the projects, specialists found excessive underground soil wetness indicators, which are classified as wetlands.
Following further assessments, it was concluded that the projects could be constructed with additional engineering work, but the project would have severe environmental impacts.
Based on this, it was decided not to continue with the solar projects.
As the largest 100% renewable generation company in Chile, we are continuously working to replace fossil fuel power generation with renewable energy, contributing to the reduction of CO2 emissions.
