Sustainability and ESG

We believe that, as a business, we need to be environmentally, socially and corporately responsible, and that our projects need to offer long-term economic, social and environmental dividends to the communities in which they exist

In Australia we have established a dedicated Sustainability Leadership Group, a cross-business group tasked with prosecuting our environmental, social and corporate governance (ESG) responsibility agenda.

See below for more information on our approach to sustainability and ESG.

Environmental responsibility

We’re continually looking for ways to reduce the level of energy usage, cut carbon emissions, increase recycling and reduce waste in our offices and projects.


Plenary is a Climate Active-certified carbon neutral organisation


Our Asia Pacific business is a certified carbon neutral organisation following certification of our 2020 operations against the Climate Active Carbon Neutral Standard - one of the most rigorous carbon neutral certification and reporting processes in the world.

In Australia we have been a member of the Green Building Council Australia for more than 15 years and we aim to achieve GBCA's Green Star rating in all of our projects.

We also use 100% recycled paper in our offices.

In North America we implement the U.S. Green Building Council’s Leadership in Energy and Environmental Design (LEED) standards and seek certification for all of our projects, resulting in sustainable infrastructure that our communities can be proud of for decades to come.

Social responsibility


We regularly pursue sponsorship and fundraising opportunities to support the communities in which our infrastructure exists.

In Australia we proudly match every dollar our Australian employees make in sanctioned donations to charity.

This has seen the Australian business and its employees donate more than $1 million to non-profit causes over recent years


We also proudly support the communities in which our projects exist, such as the three 23-year partnerships established as part of the Western Roads Upgrade projectpartnering with Western Health to improve health outcomes, partnering with the Western Bulldogs Community Foundation to support migrants and refugees (pictured), and partnering with Western Chances to help it continue to support talented young people.

Over the past five years, we have donated more than $1 million to the North American communities in which we operate. We are proud to be supporting some exceptional organizations, including

  • Covenant House - For more than four decades, Covenant House has helped transform and save the lives of more than a million homeless, runaway and trafficked young people across North America. Plenary is an annual donor to Covenant House in our local communities.

  • Taste of Soul Family Festival - Dubbed Los Angeles’ largest street festival, Taste of Soul is a free family event that takes place annually in October and attracts more than 350,000 attendees with its “soulful” food, live entertainment, local artisans and business displays. Plenary is proud to be celebrating African American culture at this outstanding event.

  • Local Food Banks - The Greater Vancouver Food Bank and the Toronto Daily Bread Food Bank provide access to healthy food, education and training to those in need. Plenary participates in annual giving and also in a volunteer program that sees up to 25 employees at a time taking shifts to sort food at the distribution warehouse.

Corporate governance responsibility

A responsible investor



In Australia we are a signatory to the world’s leading proponent of responsible investment, the Principles for Responsible Investment.

Established in partnership with UNEP Finance Initiative and UN Global Compact, the PRI works to understand the investment implications of ESG factors and to support its international network of investor signatories in incorporating these factors into their investment and ownership decisions.

The principles encourage investors to use responsible investment to enhance returns and better manage risks and, by implementing them, signatories contribute to developing a more sustainable global financial system.
