Our 2019 Sustainability Report

At Mainstream, sustainability is at the heart of our business. We are focused on making a positive contribution through our everyday actions and we remain committed to the creation of long-term value for all stakeholders on a socially and environmentally sustainable basis.
Making a positive difference in the world would be impossible without high standards of integrity and compliance.  In 2019, we have included several new initiatives within our Governance and Ethical Business area to ensure that across our business globally, we are doing business the right way.

Our Pillars

We first began to measure our performance in July 2017 across our pillars. These pillars are our sustainability framework and allow us to categorise and manage issues according to the context in which they occur. These pillars stand on the foundation of Mainstream’s unique Global Development Standard, underpinned by the Company’s seven values.

Our solid track record in developing wind and solar projects over the last ten years has made us one of the largest independent players in development globally. We have built this foundation on solid risk management and a focus on sustainability. We place a strong focus also on working with ethical business partners and supply chains to support our business objectives.

Marketplace Highlights 2019
Operating mainly in emerging markets involves managing a higher degree of risk. Our ability to manage risk in diverse global markets makes Mainstream unique and gives us a competitive edge. We closely monitor country risk, including political, social and economic risk, and monitor changes in policy, regulation, political stability and ease of doing business. Our presence in several markets allows us to spread these risks; for example, it mitigates the risk of being exposed to an economic downturn in a particular market.
We also review Transparency International’s Global Corruption Barometer and the Index of Economic Freedom on a quarterly basis. This research feeds into our risk mitigation plans, allowing us to take swift corrective action. 
Stakeholder engagement

We engage regularly with our stakeholders through on-going dialogue, employee opinion surveys, our annual Reputation Audit with business partners, investors and government representatives, and through our community engagement activities.

We have a specific process for stakeholder engagement when developing projects. This is aligned to the performance standards contained in the International Finance Corporation’s Sustainability Framework and the requirements of the Equator Principles. Our Global Development Standard guides our approach to conducting stakeholder research at a local level to ensure that it is aligned to international standards.

Reputation Risk

We are very proud of our reputation and proactively protect it by measuring our third Reputation Audit in 2019, invitingcomment from all our stakeholders,including government, regulation, suppliers, banks and finance institutions, and community representatives across our markets. The results compare favourably to previous years, and this gives us confidence that the actions taken to address perceived ‘weak spots’ have been effective.

CDP Reporting

We have participated in the annual Carbon Disclosure Project (CDP) for the last four years. In the 2019 reporting year, the CDP evaluation was aligned with the recommendations of the Taskforce for Climate-related Financial Disclosure. We were delighted to maintain our A- Leadership rating under this enhanced scrutiny. In 2019,we were also rated A- Leadership status in its Supplier Engagement Report, encouraging our suppliers to switch to renewable energy.

We are committed to the highest standards of business and ethical behaviour, to fulfilling our responsibilities to the communities which we serve and to the creation of long-term value for all stakeholders on a socially and environmentally sustainable basis. Our Code of Conduct and high ethical standards are based on shared values, reflected in our everyday actions and are documented in our Code.

Highlights 2019

  • Appointed Ethical and Compliance Manager and established global committee.
  • All Employees and Directors completed Anti-Bribery and Corruption training.
  • Modern Slavery & Human Trafficking Policy implemented.
  • Modern Slavery & Human Trafficking Questionnaire Implemented for new partners and suppliers.
  • Code of Conduct comprehensive review and bench-marking exercise.
  • Code of Conduct includes Group Compliance Policies and schedule for each region where we operate, setting out the local laws and penalties, as well as local rules around gifts and hospitality.

Mainstream's business results must always be achieved ethically and legally and the Group’s comprehensive Code of Conduct clearly defines the standards and expectations set for all colleagues. All employees, including Board Directors, sign an annual statement confirming their acceptance and observance of it. The Code is published on our website and sets out what we perceive as acceptable behaviour for employees, agents, partners and all those acting on behalf of Mainstream. The Code of Conduct was substantively reviewed in 2019 and revision includes a specific anti-bribery and corruption schedule for each region where we operate, setting out the local laws and penalties, as well as local rules around gifts and hospitality. The revised Code of Conduct includes our group compliance policies and was adopted by the board in September 2019.

The polices included in the Code are around Fraud, Bribery, Corruption, Lobbying and much more to help inform and direct employee behaviour. We also provide a whistleblowing facility for employees with concerns to report these anonymously to 'SafeCall'.

In 2019, a Global Ethics and Compliance Committee was established which is tasked with promoting ethical standards and compliance awareness throughout the company. The committee is comprised of members from each of our regions, who serve as a local point of contact for any ethical or compliance related issues, as well as a guide on aspects of local culture which can conflict with Mainstream standards.

Mainstream operates within the (UK) Modern Slavery Act 2015 and our Modern Slavery Statement is published on our website. Our Code of Conduct is substantively in alignment with the aims and the spirit of this Act. As a company, we abhor human trafficking and modern slavery in all its forms and guises. We are committed to actively ensuring that there is no room for such inhumane conduct in our own business and that of our partners, contractors and associates. In 2019, we required potential new partners and key suppliers to complete Modern Slavery and Human Trafficking Questionnaires. These questionnaires also require that anti-bribery and corruption risk measures are in place. Where we feel the results are not robust, we may insist that Mainstream’s anti-bribery training is undertaken, which is especially relevant for prospective partnership.

Our colleagues are the foundation of our business. In this pillar, we look at how our colleagues live our values in line with our Code of Conduct, the culture and environment within the company that will help colleagues to grow and develop into our leaders of tomorrow and, our workplace health and safety; ensuring a safe environment for colleagues and contractors.

Workplace Highlights 2019
Labour Practices
Mainstream's internal, State of the Art conference held in October 2019.

As a global company, it is important to create a culture that bridges the geographical divide and creates a sense of belonging that brings us together as one team.

The Mainstream Ireland office last year hosted seventy-five colleagues from its global ofices to attend a week-long induction programme.  It also held a 1.5 day internal 'State of the Art' event aimed to keep colleagues informed of both company-wide and industry-wide developments

Safety Culture
Perdekraal East Wind Farm, South Africa passed more than 1 million construction hours worked without any lost time incidents.
As we grow our business more people will be exposed to the risk of on-site injuries and we are committed to the continual improvement in our health and safety approach. We are especially aware of the need to instil in our contractors the same attitude to safety that we strive to engender in our employees. In 2019, we ran a safety culture survey throughout the company, using the Energy Institute UK Hearts and Minds cultural change programme. As a result, local culture task forces at each business were assembled to put an action plan in place to help consolidate and mature our safety culture.
We aim to embed a safety culture that is characterised by continual learning and critical reflection of our own practices.  We want to encourage an open mindset where contractors feel free to report events and learn from them. During 2019, a wide range of initiatives and campaigns to improve safety culture and reduce incidents was rolled out to employees and contractors.

We strive to minimise our environmental footprint by managing our environmental impacts. We are continually improving our management of environmental events and aim to minimise our energy consumption in our operations and to offset these through the operation of renewable energy projects in which we have a share of ownership. We have also set additional KPI's for 2020 to report on waste management across offices and project sites.

Environment Highlights 2019
We aim to minimise our energy consumption in our operations and to offset these through the operation of renewable energy projects in which we have a share of ownership. We participate in the Carbon Disclosure Project to help us enhance our measurement and management of our environmental impact and for a second year running have been awarded Leadership A- status.

We work in hazardous conditions and strive to minimise our environmental footprint by managing our environmental impacts. We are continually improving on our management of environmental events and aim to ensure the bio-diversity of the area is maintained during, and reinstated to its natural state once projects are complete.  We report on the energy consumption in our operations and in our travel, as well as the amount of emissions we offset through the operation of wind farms and solar parks in which we maintain an ownership position.

We have taken steps to reduce travel-related emissions by enhancing our technology capabilities to facilitate flexible home working and encourage video-conferencing. Our transition to a cloud-based data solution will also see reductions in emissions related to our data centres.

Mainstream takes responsibility for the environmental and ecological impacts of its activities in the development, construction and operation of renewable energy projects. We do this through implementing our environmental management systems (EMS). Our offices in Ireland, South Africa and Chile hold ISO 14001 certification.

Mainstream has a proud tradition of working to positively impact on the lives of those around us.  Our programmes include improving education in STEM subjects and environmental awareness and, enterprise development programmes play a key role to drive innovation and entrepreneurial projects in the community. 

Mainstream is a responsible developer and we recognise that working closely with our communities is a fundamental part of any project development. We engage with our communities early and often so they can be part of the project, from greenfield through to commercial operation.

Highlights 2019

  • 90 community initiatives delivered.
  • 120 teachers, facilitators employed.
  • 25,000+ community members impacted.
  • 13 project sites received community initiatives.
  • All active projects have community plans in place for 2020.
Chile - The Development Stage
We are at the early stages of our community investment plans in Chile. Our first step was to draw a stakeholder map, to get to knowthe area, understand who lives there and who we should be working with. We then engage with community leaders and partners to codesign projects and initiatives and incorporate their feedback into the programmes.
Once the programme is agreed, we sign a longterm contract with the community for the whole construction and operation period. We establish a community fund where we invest in projects that contribute to local development in their specific communities. We work in three major areas: education and capacity building, entrepreneurship and cultural heritage, which is especially important for indigenous people.
As our business in Chile moves several projects into the construction phase, we are working on projects to address the skills gap and build capacity.
South Africa - The Operational Stage
Mainstream Asset Management South Africa (MAMSA) is contracted to deliver economic development and social economic development initiatives at three operational wind plant developed and constructed by Mainstream in which it now holds a minority interest.
As our presence in South Africa is more established and our initial community programmes more embedded, we took the decision to change our strategy throughout the region. The change involves moving from a needs-based approach that can sometimes lead to a dependency on the donor, to one that is more empowering and sustainable. We call this approach Asset- Based Community Development or ABCD strategy. We have rolled it out across five wind farms and four communities.
The strategy involves convening workshops with community representatives to discuss the assets that are present in the community. Examples of these are: natural assets, economic assets, local knowledge, human resources. The next exercise is to understand the financial input and where the outflow of financial resources takes place, and whether there are opportunities to stem these flows, enriching the community by capitalising on their own resources. The second part of the workshop looks at establishing a vision for the community where the identified resources and assets are optimised. Community groups work together to draft project plans and present these to the workshop participants. A list of agreed projects is then identified, and a grant administrator appointed to provide seed funding. A follow-up meeting is organised to track progress, not just focusing on financial gain but also on other positive impacts such as social cohesion.
Vietnam - The Development Stage

In June 2019, Mainstream sponsored and hosted a one-day renewable energy capacity building event for provinces in Vietnam together with the Vietnamese Ministry of Foreign Affairs (MOFA), the Global Wind Energy Council (GWEC) and the European Climate Fund (ECF). The programme ‘Overview of renewable energy in Vietnam: Challenges and Opportunities” was attended by 50 leaders from 24 provinces across Vietnam and focused on providing an overview of:

  • the global renewable energy industry, renewable energy trends and developments in Vietnam, 
  • details of opportunities renewable energy can bring to the provinces including FDI investment attraction,
  • job creation and potential supply chain development, and
  • information on the challenges investors are facing, and the support/assistance that local authorities could provide to businesses.

Mainstream will continue to roll-out programmes in 2020 focused on areas of knowledge transfer to further enhance developing the Vietnamese renewable energy industry.
