Sustainable engineering

Within an ever changing world, to enable our operational commitments to remain sustainable we will need to understand climate change and how it affects us.  This page is aimed at providing a base understanding via a video series of – sustainability shorts – with an open discussion area to allow individuals to express opinions and open debate.  The attached questionnaire results will provide evidence if there is a requirement to include more sustainability training within the RSME group courses.

SUSTAINABILITY SURVEY

Sustainability Award

Institution of the Royal Engineers Sustainability Award
This year we again welcomed submissions for the Institution of the Royal Engineers Sustainability award. This £100 prize went to the piece of research that was judged to best create a direct impact in sustainability knowledge or practice within Military Engineering.  The winner received a copy of the Corps history, and an engraved sustainably produced timber award.

A broad range of research pieces were submitted, typically coming from existing work completed for a qualification, operational preparation, or general project work.

Previous recipients and award history – Making a Sustainable Award?

Since forming the InstRE Sustainability Forum in 2020, our driver has been to promote via collaboration and research sustainable military engineering. In 2021 the first award was presented to SSgt Dan Hall of 36 Engr Regt for his work on attachment with Balford Beatty in reducing CO2 content in concrete across their programme of works.  The following year SSgt Josh Hawes in 2022, received the award for his research into refugee accommodation delivery for HADR operations. And last years award was awarded to 39 Engr Regt resources department for work on recycling program.

Military Approach to Sustainability

Climate Change and Sustainable Engineering

InstRE Sustainability Forum

The idea that we can engineer and construct solutions in isolation from nature and the planet itself has long been dismissed.  The following content delves into the impact and solutions that engineering developments can have on the health of the planet and the security of its inhabitants.

Following a growing interest in this area by Royal Engineers across the ranks and the Institutions membership, in February 2021 the Institution of Royal Engineers placed forward a proposal to create Sustainability Forum.  So, the first question you may be asking what is the Sustainability Forum, what will it do, and we hope how can I take a part in it?

Net Zero Engineering

What is NetZero and why is it so important?

Put simply, net zero means we are not adding new emissions to the atmosphere. Emissions will continue, but will be balanced by absorbing an equivalent amount from the atmosphere.

Practically every country has joined the Paris Agreement on climate change, which calls for keeping the global temperature to 1.5°C above pre-industrial era levels. If we continue to pump out the emissions that cause climate change, however, temperatures will continue to rise well beyond 1.5, to levels that threaten the lives and livelihoods of people everywhere.  This is why a growing number of countries are making commitments to achieve carbon neutrality, or “net zero” emissions within the next few decades. It’s a big task, requiring ambitious actions starting right now.

Net zero by 2050 is the goal. But countries also need to demonstrate how they will get there. Efforts to reach net-zero must be complemented with adaptation and resilience measures, https://www.un.org/en/climatechange/net-zero-coalition

Engineering Zero is a collective campaign positioned around COP26 to advance and promote the crucial contribution engineers can make in response to the need for urgent action on climate change. It’s designed to represent and bring together the whole engineering profession and we are making good progress on the following core campaign activities:

  • Production of a series of “net zero transition” videos to promote engineering insight and expertise to government and other stakeholders.
  • Production of a series of “engineering stories” videos to highlight what engineers do within key net zero areas and raise awareness of the role of engineering plays, especially to young people.
  • Launch of a pan-profession initiative to accelerate the transformation of engineering education and skills provision in line with the demands of net zero.

To help promote the case for the latter, we have just published a new blog post, Preparing future engineers for the net zero challenge, in which Professor Roger Kemp MBE FREng argues that a fresh approach is needed in engineering education in order to support tomorrow’s engineers in managing the complex zero carbon systems of the future.

Do you have what it takes to make a Net Zero world, why not take on the challenge.   The Climate Game — Can you reach net zero? (ft.com)’

Activities 2022

  • Latest InstRE supported Sustainability Conference

    This conference aimed to understand the actions Defence and Military Engineering need to undertake today and in the future, to reduce its climate impact and help facilitate the UK’s sustainability objectives overseas, as a leader and supportive partner in this field.

  • One of our first activities was to assist the new Hacking 4 MoD programme in partnership with Cardiff and Newcastle universities, looking at carbon capture on Defence projects. Undertaken by our secretary and PEW personnel, giving advice on how infrastructure works on operations, seeing both programmes achieving great success.
  • Working with the ‘Engineers CPD Guide’ we released a series of short videos from past events looking at sustainable engineering to great wider awareness https://engineerscpdguide.com/sustainable-engineering.
  • Working with PEW and the University of Greenwich we incorporated Sustainable Engineering training into the Clerk Works and MPF training courses. https://rsme-insite.co.uk/course/view.php?id=1935
  • In April 2021 we worked with the Nuffield Research Placements group to deliver a 2-week package for six-form students, conducting climate appraisals on Briton’s recent flooding areas. https://www.nuffieldfoundation.org/students-teachers/nuffield-research-placements
  • In August working with Defence Green Networks, we helped deliver a presentation on ‘Delivering Sustainable Outcomes in Defence’, highlighting how a circular economy approach should be taken in Defence projects. https://youtu.be/3d4yFsHN6VQ
  • This was followed with our own webinar looking at ‘What is a sustainable Client’ with Maj Gen Southhall CBE and guests Sally Sudworth and Gilli Hobbs, who all set out the challenge waiting for us in our Defence projects. https://youtu.be/QQH7xFU5dRU

What are the implications of climate change on military operations and how must engineering adapt?

This year the Joint Professional Meeting (JPM) between the Institution of Royal Engineers (InstRE) and the Institution of Civil Engineers (ICE) will consider the impact of climate change on military operations.

The significant recent rise in weather extremes, United Kingdom flooding and associated disruption are all by-products of climate change; the JPM will provide a platform to discuss new climate resilience demands and what these mean for operations and military engineering.

The worldwide pandemic has demonstrated how the engineering profession is able to respond rapidly to new challenges; the impact of climate change requires a fundamental adjustment now in order to adapt to the transformed environment as we concurrently build back better post COVID-19.

Presentations will examine the new challenges being faced by the engineering profession as a result of climate change, the resilience measures needed, how the military is preparing to tackle the new threats, and what the future may hold. The meeting will culminate in a Panel Question and Answer.

 

Embodied Carbon Factors for Ground Improvement Techniques

Maj Alex Bradford

This thesis begins by exploring the climate change problem, and the current understanding of the response in terms of legislation, accounting, modelling and tools to aid decisions in construction.

There is a legal and moral need for engineers to design and construct sustainable buildings and infrastructure. These projects should meet society’s needs, support economic growth, and protect the environment. With construction-related carbon emissions accounting for 34% of global emissions and gross construction emissions increasing annually, the industry must make drastic changes to achieve its Net-Zero target by 2050.

Achieving this goal requires transparent, data-driven decision-making by clients and designers throughout the construction process, ensuring that carbon emissions are carefully considered at every stage. Geotechnical engineering (primarily found in the initial stages of a project) presents a difficult challenge when trying to model for carbon emissions, due to the huge variability in ground conditions and methods employed (from cement stabilisation and piling to basic cut and fill excavation). Existing emissions databases and carbon accounting tools are underdeveloped or are absent of soil modules.

Global GHG emissions under different scenarios (UNEP, 2022)

It is the role of the engineer to ensure the best estimation possible, based on the information available at the time. If the engineer is unable to influence this and exercise engineering judgement, the carbon forecasting becomes less accurate, potentially leading to a significant difference between forecast and reality. Key to this is the improvement of communication and decision making when considering carbon emissions in ground improvement techniques where accessibility, ease of use, and clarity should be prioritised. Initially, published guidance, on the relative qualitative emissions of different techniques can inform decision makers at the concept stages of design, but this needs to be developed and monitored through the project life cycle.

One of the recommendations from the thesis is that free to use comparison tools, such as Carbone is used to assist with detailed or technical design. Although this sounds obvious, it is not always utilised, even when available. It is most important, that any ground improvement carbon calculator should be integrated with an overall construction design tool that allows designers to consider economic and carbon efficiencies holistically for the entire project or scheme, including any remedial ground works required.

Introduction
I am sure every one of us in the UK supports cutting waste, not polluting the oceans with plastic, collecting our rubbish (though people are still throwing tons of waste out of car windows), reducing discharges of all types into our fragile atmosphere and still maintaining a reasonable lifestyle. To do this we need to plan, engineer and build in a sensible way. What we cannot afford to do is inflate electricity prices and other costs: this will simply result in manufacturing industry leaving the country and the export of our carbon dioxide emissions.
