The Global Status Report for Buildings and Construction (Buildings-GSR), a report published by the UN Environment Programme (UNEP) and the Global Alliance for Buildings and Construction (GlobalABC), provides an annual snapshot of the progress of the buildings and construction sector on a global scale. The Buildings-GSR reviews the status of policies, finance, technologies, and solutions to monitor whether the sector is aligned with the Paris Agreement goals. It also provides stakeholders with evidence to persuade policymakers and the overall buildings and construction community to take action.

As outlined in the latest edition, the buildings and construction sector contributes significantly to global climate change, accounting for about 21 per cent of global greenhouse gas emissions. In 2022, buildings were responsible for 34 per cent global energy demand and 37 per cent of energy and process-related carbon dioxide (CO2) emissions.

The 2022 update of the Global Buildings Climate Tracker (GBCT) paints a concerning picture: the gap between the current state and the desired decarbonisation path is significant. To align with the 2030 milestone, an annual increase of ten decarbonisation points is now required, a substantial jump from the six points anticipated per year starting in 2015.

This year, the deep dive chapters are the following: Adaptation and resilient construction methods; Innovations in business cases as well as Nature-based solutions and biophilic design.

When it comes to sustainability and circularity, wood as a natural raw material has several advantages over other building materials. As a bio-based resource, it has considerable benefits concerning greenhouse gas emissions, carbon-storing, thermal insulation as well as human health and well-being compared to other construction materials. New types of wood products, being the result of extensive research, enable the extensive use of wood in tall buildings. At the same time, innovative wood products provide less manufacturing waste, low carbon-emission alternatives and store massive quantities of carbon while new technologies speed construction processes, promote energy efficiency and minimize waste.

This study examines the benefits of wood as a construction material and discusses practices applied in the wood construction sector from the perspective of circularity, sustainability and climate change mitigation. It analyses how circularity concepts can be applied in the construction industry using different construction methods and at different stages of value chains. The study describes how different construction techniques and practices contribute to the renewal and sustainability of construction value chains. The analysis is supported by examples of good practice in UNECE member States.

The Cooling Web is a guidance document and a compilation of case studies that bring out a range of cooling solutions that are diverse and comprehensive and do not rely on conventional energy-guzzling practices. This involves measures to enhance microclimate, thoughtful designs for building envelopes, judicious selection of material, and context-specific cooling approaches.

India is witnessing rising frequency and intensity of heat waves. This is making our cities sear and pushing the built environment community to rethink how to plan and design buildings and cities. This momentum is strongly linked with the India Cooling Action Plan 2019 and its very important goal of thermal comfort for all. The Union government and a few state governments are taking strides to achieve this goal by developing thermal comfort standards and action plans, adopting energy conservation building codes, and other initiatives like cool roof programmes. However, the degree of success lies in the scaled-up implementation of cooling strategies.

The 10 case studies in the volume 1 carefully selected from across the country—with five deep dives—highlight how thermal comfort can be achieved by a combination of passive and active cooling measures. This approach reduces cooling energy demand tremendously and addresses cooling equity. These solutions blend traditional wisdom on passive design with modern techniques and provide optimized solutions so that energy consumption is minimized. These solutions are also a guide toward achieving a rational and climate-appropriate cooling ecosystem that not only ensures resource efficiency but also maintains thermal comfort for building occupants.

The GCCA Sustainability Charter and Sustainability Guidelines underpin the sustainability activity of its member companies, setting out what they need to abide by, what they measure and how they report their sustainability performance, especially for Cement and Concrete Manufacturers, providing global guidance on aligning their sustainability and ESG (Environmental, Social, and Governance) principles. These guidelines offer industry-leading Key Performance Indicators (KPIs) and parameters tailored to the sector, empowering Sustainability Managers, ESG Managers, and Plant Managers to effectively manage their sustainability performance.

This guideline outlines five key pillars that encompass the full spectrum of sustainability within the cement and concrete sector. It establishes specific requirements for full members to meet in each of these pillars.

The GCCA sustainability guidelines feature a set of straightforward, reliable, and representative KPIs that members must use to monitor and report their performance. To achieve the highest level of compliance, full members are expected to have their data independently verified and made publicly available.

The Global Cement and Concrete Association is an international industry association that was established in 2018. as of 2018, it represented about 35% of the global industry for Cement and Concrete.
