Concrete New Zealand (ConcreteNZ) published A Net-Zero Carbon Concrete Industry for Aotearoa New Zealand: Roadmap to 2050 .

The roadmap outlines the New Zealand cement and concrete industry’s commitment to achieve net-zero concrete production by 2050. The roadmap sets targets for a 44% reduction in direct and electricity-related greenhouse gas emissions by 2030, aligning with global standards.

The roadmap also showcases the industry’s efforts and innovations to reduce emissions and enhance the sustainability of concrete, and it aims to support the New Zealand government’s climate change goals and contribute to the global net zero movement.

RMI’s insight brief The 3Cs of Innovation in Low-Carbon Concrete: Clinker, Cement, and Concrete provides a one-stop shop for understanding the landscape of emerging and alternative technologies to decarbonize concrete and cement. The insight brief details the pros and cons of each innovation and provides a technology’s applicability evaluation framework for assessing which of these technologies are most effective for their unique conditions.

The concrete and cement industry currently accounts for 7-8% of global CO2 emissions, and the sectoral emissions will continue to increase if we keep making concrete the way it is produced today. The coming years will see significant growth in demand for concrete, particularly in the Global South, which means bringing many brand-new plants online. This provides a prime opportunity for investing in low- and zero-carbon concrete and cement production capacities to avoid locking in emissions for decades.

There is no silver bullet to decarbonize concrete and cement. On the one hand, the technologies that are readily available today, such as energy efficiency improvements, will not get us to net-zero by 2050. On the other, the most mature carbon capture technology today can achieve significant emission savings, but is expensive and energy intensive. Many policy-makers, investors, researchers, and industry stakeholders have expressed interest in understanding the new and emerging technologies that can accelerate the sectoral transition.

The World Green Building Council’s (WorldGBC) Europe Regional Network (ERN) has released a policy briefing which provides detailed guidance on Whole Life Carbon (WLC) reporting and target setting in the built environment.

Buildings account for around 40% of energy consumption and 36% of carbon emissions in Europe, which includes both the operational carbon of buildings from when they are in use, as well as the carbon impact of the manufacturing, transportation, construction, and end-of-life phases of built assets, often called embodied carbon. Meeting the EU Green Deal’s goal of carbon neutrality by 2050 will require policymakers to introduce measures that address the Whole Life Carbon (WLC) impact, both operational and embodied carbon, of buildings.

WorldGBC’s policy briefing gives recommendations on how the European Commission and EU member states should implement three key aspects of WLC policy when it is formally introduced into key legislation such as the Energy Performance of Buildings Directive (EPBD).

The three main sections of the paper cover recommendations on how to harmonise and standardise WLC reporting, plus how to define the physical scope of a building for WLC assessments, and how to construct WLC targets (known as the ‘architecture’ of WLC targets).

This report shows how the building industry can bring up-front materials emissions down to zero. It explores our current understanding of cradle-to-gate (CtG) embodied carbon emissions, otherwise known as up-front emissions from materials captured in lifecycle phases A1-A3, in new home construction and the building industry’s ability to mitigate these emissions down to zero (or even to become net carbon storing). We demonstrate how this can be done without any negative repercussions for continuing efforts to bring operational greenhouse gas (GHG) emissions to zero, providing the market with clear directions for fast, practical, and cost-effective change.

Architecture 2030

The CARE (Carbon Avoided: Retrofit Estimator) Tool is used for estimating and comparing the embodied, operating, and avoided carbon impacts and benefits of reusing and upgrading existing buildings or replacing them with new construction. The CARE Tool allows users to compare the total carbon impacts of renovating an existing building vs. replacing it with a new one.

The CARE Tool is an Architecture 2030 Project.

This document highlights ten case studies of policies driving lower carbon construction across the Pacific Coast. Each case explores the development process, challenges faced, and lessons learned through the policy process. Information was gathered from interviews with PCC members who were involved in the policy, publicly available policy reports, as well as interviews from the implementing agency of the policy.

Africa is the fastest-growing region in the world. Unfortunately, current construction in Africa is highly dependent on imported construction materials with high negative environmental impacts. The new SBC publication Unlocking the Potential of Local Circular Materials in Urbanising Africa and video present a building concept for high-density neighbourhoods that promotes the use of responsibly sourced local materials.

With India being the world’s second-largest producer and consumer of steel, any meaningful global shift towards low carbon steelmaking must be based on an understanding of India’s unique context and circumstances. The India Net Zero Steel Demand Outlook Report is an important step in building this understanding as it evaluates the Indian market for net zero steel and the factors that will drive this demand in the decades to come. The report brings out the economic and decarbonisation opportunity available to Indian steel makers today and makes a case for the adoption of low carbon technologies for steel production.

This report - Sri Lanka Roadmap for Sustainable Housing and Construction 2020 – 2050 - presents the findings of the Sustainable Building Construction Country Assessment for Sri Lanka (SBC-CA) and a Roadmap for Sustainable Housing and Construction and achieving NDCs in the construction industry in Sri Lanka. It examines the current status, and potential opportunities and challenges for adopting Sustainable Building Construction (SBC) practices and policies. The Country Assessment and the Roadmap are structured on the approach laid out by the ‘Global Alliance for Building Construction (GlobalABC) Roadmap for Buildings and Construction 2020-2050, where 8 Action Areas have been identified for the transition towards sustainability in the Construction Sector: Urban planning, New Buildings, Existing Buildings, Building Operations, Appliances and Systems, Materials, Resilience, and Clean Energy.

The Global Status Report for Buildings and Construction (Buildings-GSR) is a flagship publication of the UNEP-hosted Global Alliance for Buildings and Construction (GlobalABC). The Buildings-GSR provides an annual snapshot of the progress of the buildings and construction sector on a global scale and 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.

What is new in the 2022 Buildings-GSR

  • Buildings and construction: disruptions and challenges facing the buildings sector in 2022 
  • Global Building Carbon Tracker: Are we on track towards the Paris Agreement Goals?
  • Updates on building codes and building decarbonisation in Nationally Determined Contributions (NDCs)
  • Status of investment in building energy efficiency
  • Deep dive on:
    • Africa (regional focus)
    • Building materials (topical focus)

The 2022 Buildings-GSR finds that 

  • Despite a substantial increase in investment and success at a global level lowering the energy intensity of buildings, the sector’s total energy consumption and CO2 emissions increased in 2021 above pre-pandemic levels. Buildings energy demand increased by around 4% from 2020 to 135 EJ – the largest increase in the last 10 years. CO2 emissions from buildings operations have reached an all-time high of around 10 GtCO2, around a 5% increase from 2020 and 2% higher than the previous peak in 2019. 
  • The buildings and construction sector is not on track to achieve decarbonization by 2050. And the gap between the actual climate performance of the sector and the decarbonization pathway is widening.
  • Global energy price volatility and rising interest rates are likely to hamper investment in building decarbonization by governments, households, and businesses.
