A forward-thinking approach to health and safety and our environmental impact is of paramount importance. We endeavour to maintain a culture of continuous improvement to build upon our excellent record. We are driven by the beliefs of our employees and our responsibility to minimise our impact on the environment. Our commitment stems from the clear benefits of sustainable practices.
We safeguard the health and safety of everyone working on site. All employees are encouraged to take an active role in ensuring that our working environment is a safe place to work and visit. Employees report all observations, engage in safety audits, assessments and attend regular training sessions. During the year, we held monthly global Health and Safety meetings where information, knowledge and ideas are shared to implement best practice across our sites and create a positive attitude towards safety. In addition, our management teams put considerable focus on potential hazard reporting, to ensure the appropriate action is taken before any incident or an accident can occur.
Throughout our activities, we look to reduce the energy we use through resource saving solutions. At our U.K. facility for example we have completed our LED Project, replacing all lighting both internally and externally with energy saving LEDs. We have also begun the process of monitoring the energy output of our manufacturing equipment. We will be continuing to make steps towards using less energy throughout 2021.
We have employees based in each of our facilities who are responsible for collecting, monitoring and acting on data regarding our greenhouse gas emissions. The collected data allows us to monitor and examine carbon emission trends and track progress against our internal sustainability goals.
A number of factors have contributed to the Group’s energy performance during the year including the acquisition of two additional manufacturing sites. With revenue for the year at £168m and the total emissions of carbon dioxide equivalent to 6,748 tonnes, this gives an intensity ratio of 40 tonnes GHG per £million revenue.
Our staff actively engage in waste material separation with a focus on re-use where possible, and recycling of paper, metal, plastic, cardboard and used products. We monitor our electricity, gas and water usage frequently to establish progress against our annual targets.
With evolving environmental legislation globally, we ensure compliance through regular updates to our processes demonstrated by our continued membership of the Institute of Environmental Management and Assessment. 4 of our 7 sites are certified with the other 3 in transition. Our U.K. operations is also certified to conform to ISO14001:2015, which reinforces how we manage our environmental responsibilities.
We will continue to drive towards a world-class level of safety performance, focusing on the management and reduction of risk. This forms part of our continuing efforts to build a culture of responsible behaviour and ethical decision-making. In 2021 we aim to make improvements to reduce energy consumption and to further reduce waste going to landfill. We will drive strong environmental performance through enhanced practices and visible leadership and we will also focus on developing environmental contingency plans for our facilities.
