Carbon Emission Reduction

Building a Clear Path to Carbon Reduction with Tunley Environmental

At Crown Plus, environmental responsibility is central to everything we do. Wherever practical, we repair and restore existing assets instead of replacing them, helping to reduce waste, minimise disruption and lower the environmental impact of our work. We also seek to recover and reuse materials on site wherever possible, supporting a more circular and sustainable approach to infrastructure maintenance.

Our Challenge

Although sustainable working practices were already embedded across many areas of our operations, we wanted to formalise our approach to carbon management and reporting.

To make meaningful progress, we needed a clear and credible understanding of our emissions, where they were being generated and which actions would deliver the greatest reductions. We also wanted to establish a practical framework that our teams could follow across the business and in the field.

Our key objectives were to:

  • Establish a credible carbon emissions baseline
  • Understand the main sources of emissions across our business
  • Improve the consistency of our environmental reporting
  • Identify practical carbon reduction measures suited to our operations
  • Create a structured approach for measuring progress over time

Our Partnership with Tunley Environmental

We partnered with Tunley Environmental to undertake a comprehensive Business Carbon Assessment covering our baseline year from 1 January to 31 December 2024.

The assessment was led by Tunley Environmental’s PhD-level scientist, Dr Anusha Nawoor, and was completed in line with ISO 14064-1 and the Greenhouse Gas Protocol.

Working closely with our team, Tunley examined emissions across Scopes 1, 2 and 3, giving us a detailed picture of our carbon footprint. The process helped us understand not only the scale of our emissions but also the operational activities responsible for them.

Importantly, the assessment went beyond measurement. Tunley worked with us to develop a clear roadmap towards net zero, supported by practical carbon reduction initiatives tailored to the realities of our fleet, sites, workforce and wider supply chain.

Understanding Our Carbon Footprint

The Business Carbon Assessment calculated our 2024 baseline emissions at 1,191.5 tCO₂e, comprising:

Scope 1 – primarily arising from fleet and operational fuel use
0 %
Scope 2 – associated with purchased electricity
0 %
Scope 3 – including employee commuting, waste, business travel, capital goods, and purchased goods and services
0 %

The results showed that the majority of our carbon footprint sits within Scope 3. They also highlighted the importance of addressing emissions associated with our fleet and operational activities.

This evidence has given us a much stronger foundation for decision-making. We can now focus our efforts on the areas where change will have the greatest impact, set meaningful priorities and measure our progress consistently.

“Working with Tunley has turned carbon reduction into something practical and trackable, rather than simply an ambition.”

Our Carbon Reduction Roadmap

Based on the opportunities identified through the assessment, we now have a roadmap designed to deliver a 52% reduction in total emissions by 2040.

Our planned initiatives include:

  • Transitioning to renewable energy
  • Implementing a zero-landfill policy
  • Optimising and upgrading our fleet
  • Working with lower-carbon suppliers
  • Encouraging more sustainable employee travel

These initiatives provide us with a structured and realistic route towards reducing emissions across our operations and supply chain.

Turning Ambition into Measurable Action

Our partnership with Tunley Environmental has enabled us to move from broad environmental ambitions to an evidence-led carbon reduction strategy.

Net Zero

A clear roadmap towards net zero across our fleet, sites, workforce and wider supply chain

With a credible baseline and a clear reduction roadmap in place, we can monitor our performance, prioritise the most effective actions and demonstrate measurable progress to our clients, employees and stakeholders.

The assessment has also reinforced the importance of beginning with accurate data. A business needs to understand its current position before it can set credible targets or make informed decisions about the future.

“If you’re serious about reducing your carbon impact, you need a proper baseline first. The assessment gives you a clear picture of where you are and the practical steps you can take next.”
