John Sisk & Son 2030 Sustainability Roadmap

Building today, caring for tomorrow

Creating a sustainable legacy across the construction industry

Sustainability and social value 

These key topics are at the core of that ambition and we are determined to deliver a positive environmental impact for our business, suppliers, clients and neighbours. 

We want to be a market leading contributor to social value creation through the promotion, measurement and celebration of all our CSR activities. As we continue to grow and expand our business, we are becoming the employer of first choice for many in our industry with an exciting and innovative culture.

Energy awareness & efficiency

We are embedding a culture of energy awareness & efficiency in our day to day operations with a view to reducing our carbon footprint and reducing our cost base where practical. 

This involves measuring, monitoring and assessing our operations to achieve continual improvement and to enhance performance in line with our objectives and targets, whilst meeting our compliance obligations.

We have mandated that all electricity supplies to our offices and sites are procured from renewable sources and the installation of smart meters on all our sites.

Green Awards 2020

We are delighted to have won two awards at the Green Awards in Dublin. The Sisk team won the Green Construction Award and Green Business of the Year. The Green Business of the Year was selected by the judging panel from all the winning categories on the night and is an outstanding achievement for Sisk.

Both awards are recognition for our business having taken great strides to delivering our carbon reduction agenda over the past year.

The Green Awards recognise the extraordinary contribution and commitment that companies make towards growing a greener future in Irish business.

Our sustainability team takes a collective approach to implement innovation

Electric vehicles

Sisk is proud to be a member of EV100. This is a global initiative bringing together companies committed to accelerating the transition to electric vehicles (EVs) and making electric transport the new normal by 2030.            

Since committing to electric vehicles in 2019 Sisk has made significant strides forward. We have installed fast chargers at our offices in Dublin, Cork, Galway and Warrington in the UK. We are well on our way to meeting our target of 100 electric fleet vehicles by 2023.

Green suppliers

Sisk ensures that decisions taken regarding the procurement and engagement of any organisations, individuals, goods or services are governed by integrating environmental, legal, social and economic considerations into all stages of the procurement process.

Our procurement teams actively seek to collaborate with clients, consultants, specialist contractors and suppliers to develop integrated supply chains which respect biodiversity and human rights and promote fair employment practices.

Our achievements

Obtaining a commitment from Grafton, Ireland’s largest builders merchants, to obtain FSC Certification and supply our projects exclusively with sustainable timber.

• Achieving an embodied carbon saving of 96% - by implementing a GGBS cement substitute for concrete across our projects.

• Acquiring Vision Built, an off-site fabrication business of innovative, sustainable and recyclable steel. We aim to grow this business for use across all of our projects.

Recycling and decreasing waste

Sisk forecasts, continually monitors and targets waste reductions throughout construction from project inception to completion. We engage with our supply chain to identify and target reductions in waste stream generation.

We provide effective and progressive management of waste on-site through the use of supplier take-backs and recycling services.

Our site teams engage with first class waste contractors with advanced systems to ensure Sisk waste is expertly processed following the waste hierarchy for reuse, recycling and recovery prior to disposal as a last resort.
