Reducing our emissions

Reporting our greenhouse gas emissions

We have robust monitoring and reporting procedures in place for greenhouse gas emissions. We report our emissions in line with all applicable mandatory reporting requirements, and report voluntarily on the business risks and opportunities of climate change via CDP’s disclosure programme.

We have voluntarily responded to the CDP climate change programme for the last 5 years. In 2018 we achieved a score of B, demonstrating our ‘Management’ of our greenhouse gas emissions, and performing above the construction sector, general CDP response, and European regional average of B-.

 CDP Score 2018

We are committed to responding to CDP annually and to improving our level of disclosure and performance. As a ‘supplier engagement leader’ we also support our customers by reporting the emissions associated with our service delivery, where requested.

Our latest response can be viewed on the CDP website.

Reducing our emissions

In 2018 we have continued to reduce our global greenhouse gas emissions in line with climate change science.


ISG has committed to setting emissions reductions in line with science-based target methodologies, and we are currently working towards approval with the Science Based Target initiative (SBTi).

Due to the contract-based nature of our business, our emissions can increase or decrease significantly based on the type of work that we carry out each year, and whether or not we pay for energy used on our sites. To minimise this volatility, we report our emissions on a 3-year rolling average basis from our baseline.

When comparing the rolling average emissions figure to our 2015 baseline, ISG has reduced emissions in 2018, within the boundary of its target, by 39%. However, we must continue to mitigate our emissions impact across the business to ensure that we remain on-track to achieve our long-term 2050 goal.

Moving forward, we have reset our baseline on our 2017 scope 1 and 2 greenhouse gas emissions, inclusive of more comprehensive and robust data capture. Using the same science-based methodology we have established draft targets to reduce our total scope 1 and 2 emissions from our 2017 baseline by 53% by 2050.

With regards to our scope 3 emissions, in 2019 we will be reviewing emissions associated with goods and services purchased through our supply chain. Once finalised, these shall be combined with our scope 1 and 2 emissions reduction targets, in line with science-based methodologies.
