This initiative marks a decisive step in fib’s strategic vision to support and guide the civil engineering community through the digital transformation that is reshaping the construction industry worldwide. fib recognizes the critical importance of this moment and reaffirms its commitment to proactively guide this transition by initiating the Special Activity Group on AI and Digitalization.
Scope and objective of technical workTo achieve its goal, the SAG will focus on three objectives:
The SAG will operate through two dedicated working parties, ensuring that AI integration is addressed both at the strategic and operational levels, with a strong foundation in ethical responsibility and human oversight.
Working Party 1 is dedicated to exploring the short- and long-term implications of AI adoption in the field of structural concrete. Its work will be guided by a clear focus on maintaining engineering integrity while embracing the opportunities presented by digital technologies. A vital aspect of this group’s mission will be to address the ethical considerations of AI use. As AI tools grow in capability, it is essential to reaffirm that engineering judgment, personal accountability, and ethical standards must remain central.
Working Party 2 will focus on transforming fib’s vast technical knowledge into practical digital tools. By leveraging the federation’s extensive library of design codes, guidelines, and scientific reports, the group will explore the development of domain-specific AI language models to make expert knowledge more accessible and actionable.
The SAG will carry out a series of targeted activities aimed at guiding the responsible integration of AI into structural engineering. This includes defining a long-term vision for AI’s role in the field, conducting sector-wide surveys to identify current challenges and opportunities, and developing data governance frameworks to ensure trustworthy deployment. A central goal is the creation of an AI knowledge platform that builds on fib’s technical heritage, making expertise more accessible and usable. These efforts will reinforce fib’s commitment to global knowledge exchange, technical excellence, and innovation in structural concrete.
As structural engineering enters the age of digital intelligence, fib invites researchers, practitioners, industry leaders, and stakeholders worldwide to join this initiative and help shape the future of structural concrete.

In 2021, the fib issued an official statement outlining its achievements to date and reaffirming its commitment to sustainability goals. Building on this foundation, and following further discussions in 2022, the Special Activity Group on Sustainability was formed to advance this agenda. The fib’s efforts to reduce CO₂ emissions throughout the lifecycle of concrete buildings and infrastructure are now making significant progress, supported by valuable contributions from member organisations. This roadmap is intended to strengthen these efforts, providing a central framework for the fib’s sustainability initiatives.
The “fib Carbon Reduction Roadmap to 2050” is designed to guide the fib’s internal efforts and shape its external communications. We recognise that achieving carbon neutrality poses a considerable challenge, requiring technological innovation and close collaboration among suppliers, designers, builders, and owners. The fib is uniquely positioned on the international stage to encourage its members to meet this challenge boldly and to bridge the gap between research and practice.
This document considers four building lifecycle stages in line with EN 15978: A – Product and Construction Stage; B – Use Stage; C – End-of-Life Stage; and D – Beyond End-of-Life Stage, which includes reuse and recycling.
Roadmap to carbon neutrality and the role of fib members
The fib is committed to leveraging its expertise and resources to achieve the overarching goal of reducing CO₂ emissions from structural concrete by 50% by 2035 and reaching net zero by 2050 for both new and existing structures, as illustrated in Figure 1.
Figure 1. Timeframe for carbon neutrality by 2050.
We recognise that the proportion of CO₂ emissions reductions will vary across different types of concrete structures and regions. We also recognise that the challenges associated with achieving reductions in Stages A, B, C and D vary. For A and B technologies are becoming increasingly mature, whereas Stages C and D will require substantial changes to current practices, and such efforts must begin immediately.
Carbon considerations across the building lifecycle
As illustrated in Figure 2, various stakeholders have distinct opportunities to impact carbon reduction. Suppliers can concentrate on researching and developing low-carbon, ultra-durable materials for Stages A1 to A3. Designers play a critical role in decision-making, proposing low-carbon technologies that encompass material selection (Stage A) through to dismantling and recycling (Stages C and D) to achieve a minimised lifecycle assessment (LCA). Builders contribute to carbon reduction by adopting sustainable material procurement and construction methods in Stage A, which helps to lower the overall LCA. Additionally, by ensuring quality during construction, builders enhance durability across the structure’s lifespan (Stage B).

Owners are responsible for implementing conservation plans and gathering data during Stages B and C, and they can further improve resilience in existing structures. They also play a key role in evaluating options for reuse and recycling to extend a structure's lifecycle.
A conceptual diagram illustrating the longevity of a structure and associated CO₂ emissions with both current and low-carbon technologies is presented in Figure 3.

Extending the life of existing structures
The lifespan of existing structures should be extended as much as possible, with demolition and reconstruction considered only as last resorts. Where feasible, it may be more beneficial to repurpose the structure for a new function without demolishing it.
For existing structures, calculating the lifecycle assessment (LCA) from the point of intervention through to the end of life is essential. Since interventions involve construction activities that emit CO₂, the optimal construction method should balance the duration of the intervention with the associated CO₂ emissions, considering its impact on social activities. Additionally, existing structures should be designed to be resilient, minimising damage and reducing CO₂ emissions related to repair and recovery.
Minimising lifecycle costs through carbon pricing can help identify the most effective solutions. Decisions regarding interventions should be based on the total CO₂ emissions cost, converted to monetary terms via carbon pricing.
How to achieve carbon neutrality
The solutions that are available now or need to be developed for each stage are shown in Table 1.
Table 1. Currently available and future solutions for each of the construction stages A-D.
Progress review
The overall goal of the fib is to support and promote halving of CO₂ emissions by 2035, recognising that it is not the role of the fib to collect and aggregate carbon emission data.
Members can share their progress achieved towards the goal of fib at events, particularly at the fib 2030 Congress in Japan, where a dedicated session will be held to showcase advancements made towards this goal. Based on the progress observed in 2030, the roadmap may need to be redefined.
The fib will update the General Assembly and its membership annually the progress achieved against this roadmap.
The vision for fib Model Code for Concrete Structures 2020 (MC2020), as a single merged general structural code, goes beyond the point reached by fib MC2010, recent ISO codes, such as ISO 16311, and the current Eurocode activities to extend their application to existing structures. The envisaged development is intended to result in an internationally recognized and comprehensive fib Model Code 2020 for new and existing concrete structures. This work is to be taken forward by TG10.1: Model Code 2020. It is clear from discussions at the TC that Commission 10 and TG10.1 should have wide international representation.
The fib Model Code for Concrete Structures 2020 is only available in PRINTED version. Please select the DHL shipment as your delivery option when you make your order. Please be aware that shipping may take 3-4 weeks, depending on your location. The electronic version is accessible via the online viewer depending on your subscription but a PDF version cannot be purchased nor downloaded.
fib MC (2020) presents new consensus guidance on developments relating to concrete structures and structural materials, as well as providing a basis for future codes for concrete structure. It addresses significant advances made on a wide range of issues including those relating to structural design and analysis methods, seismic design and assessment procedures, durability, structural monitoring, service life design, structural assessment through-life and making interventions to adapt existing structures or enhance their performance to accommodate revised requirements or extend their useful life.
fib MC (2020), like previous editions of the fib Model Code, not only specifies requirements and recommended practices, but gives explanations in the adjoining informative column of the document.
A series of articles written by experts and related to the fib Model Code for Concrete Structures 2020 is available on Wiley website. Please make sure you are logged in as a fib member to access all the articles.
