The objective of this report is twofold. First, based on an expert workshop and a literature review, it aims to integrate the state of knowledge on the concepts of EE1st and MI. This concerns the theoretical interlinkages between the two concepts as well as the possible role of different decision-support frameworks (e.g. cost-benefit analysis) and evaluation perspectives.

Second, the report provides evidence on the magnitude of selected MI from a model-based assessment for the EE1st principle in the EU-27. Three scenarios are compared for the MI of air pollution and indoor comfort. We find that factoring in MI certainly affects the trade-off between demand-side and supply-side resources, making it critical to include them in model-based assessments in the scope of EE1st

In light of EU climate goals and Russia’s invasion of Ukraine, significant measures are needed to decarbonise the economy, reduce energy use and future-proof the building stock. With 75% of Europeans living in urban areas and a rising focus on existing buildings to achieve full decarbonisation by 2050, there is significant opportunity and need to focus on innovative solutions in neighbourhoods and homes, beyond the individual building level. Successful decarbonisation of the EU building stock calls for an integrated, participatory and neighbourhood-based approach.

The Green Deal, introduced by the European Commission in early 2020, aims to make the European economy carbon neutral by 2050. In order to achieve this neutrality, European countries are developing their climate roadmaps for each sector, including the building sector. In order to assist players in the sector, OID provides a study on current practices and strategies in the building sector of the following countries: France, England, Germany, Italy, Spain, Belgium, Luxembourg, the Netherlands and Denmark.

European Union

Level(s) is a European framework to help built-environment sector professionals assess and monitor the sustainability performance of buildings. If you operate an assessment or certification scheme in the European Union, the publication "Level(s), A common language for building assessment" can help you understand how Level(s) complements your work. 

If you are interested in Level(s) but unsure where to start, don’t worry. The Level(s) eLearning programme will help you to get going. The eLearning programme is also the perfect resource for users with some experience of Level(s) who want to improve their understanding in one or more aspects of the European common language for sustainable buildings.

If you are using Level(s), the European framework for assessing the sustainability performance of buildings, you can access the European Commission’s free Calculation and Assessment Tool (CAT) to help you create Level(s) assessments for building projects. CAT is there to support you to complete life cycle assessments using Level(s) during the different phases of building design, construction and maintenance or de-construction.


In the past two years, our ambition and commitment to advance change led to achieving major advances in analysing and promoting buildings and energy demand policies, in new research on building sector policies and business models.

Putin’s aggression in Ukraine, the COVID-19 pandemic, and soaring energy prices in Europe, have led to a fundamental rethinking in the area in which we focus our work. These developments, in combination with the ever-starker warnings of the climate science community allow only one conclusion: We need to accelerate positive change and be bold, in both our thinking and our actions.

What underpins our strategic decisions and daily work is the will and desire to ask the hard questions: How can Europe become the climate champion it committed itself to be? And how can the built environment support and encourage a truly sustainable – and affordable – lifestyle for all? 

With this biennial report, we are sharing our story and achievements of the years 2020-2021 and intend to provide a window into who we are as an organisation, how we are delivering positive impact and how we are moving towards bigger thinking and bolder action so we can achieve truly climate-neutral buildings.

UK Parliament

From residential to commercial buildings, the UK’s built environment is responsible for 25% of the UK’s greenhouse gas emissions. The Environmental Audit Committee (EAC) warns that to date there has been a lack of Government impetus or policy levers to assess and reduce these emissions. With climate deadlines looming, urgent action is needed.

This study shows how improving insulation can reduce energy demand and drastically cut Russian oil and gas imports for heating in buildings. Investing in building renovation can reduce the use of fossil fuels for heating in buildings, reaching 44% in gas savings, save 45% of final energy demand and substantially contribute to securing the EU’s energy needs.

On 24 May 2022, WorldGBC launched the EU Policy Whole Life Carbon Roadmap for buildings as part of the #BuildingLife project.

This Roadmap outlines the key European Union (EU) policy interventions, regulatory measures and tools needed to achieve a decarbonised, circular, resilient and well-designed built environment by 2050. It focuses on measures to address whole life carbon (WLC) at the building level.

Created as part of the #BuildingLife project, this Roadmap provides:

  • A reference for European policymakers to guide decision-making in relation to key EU built-environment policy packages to ensure they align with global and European climate and energy goals;
  • Aresourceforpolicymakersatnationalandsubnationallevels to understand how to harmonise multi-level governance to accelerate action on WLC;
  • Aguideforanyonewishingtounderstandwhattrajectorypolicy (particularly EU policy) must take to ensure the built-environment sector delivers on the EU Green Deal and Paris Agreement;
  • A resource giving organisations across the sector a common position, building impetus for greater policy ambition.

The built environment offers significant carbon mitigation potential: decisive policy action will not only address the ongoing climate emergency we are facing, but will also directly reduce energy costs and improve security of supply, and has the potential to create widespread business opportunities and significant numbers of new, local jobs. Based on this context, the study presented in this report was developed at the request of the Brazilian Ministry of Mines and Energy (MME) within the framework of the Specific Partnerships for Implementation of the Paris Agreement (SPIPA). This report discusses policies, tools and market initiatives aimed at reducing upfront emissions – that is, the embodied carbon associated with building construction, including the extraction and processing of materials.

This policy briefing finds that the European Commission’s December 15th EPBD recast proposal does not yet reflect the crucial role the EPBD should play within the Fit for 55 Package and within the greater narrative of securing energy independence. While it is welcome that many provisions are either introduced or open for modification, they will not deliver on the Directive’s objectives if the ambition is not set at the right level, and if measures are not made more stringent and coherent.  Ultimately, the scope of the EPBD recast proposal is incomplete, as the updated 2050 vision for the building stock only considers the operational phase of emissions from buildings. The long-term vision is also unbalanced, with a focus on reducing operational greenhouse gas emissions mainly through a full switch to renewables, while the “energy efficiency first” principle is not reflected in the outlined provisions. With the legislative process starting, there is now an opportunity to ensure the final Directive is improved and fully aligned with the EU 2030 and 2050 climate and energy efficiency objectives.
