Greenhouse gas emissions (GRI)

Explanation of the material topic and its Boundary (GRI 103-1)

Overall research shows that global warming as a result of human activity is a serious threat to the ecosystems that ensure the conditions for life as we know it on our planet. All of Bonava’s identified material environmental aspects have climate relevance. Bonava has direct organisational control over only 2 per cent of the total climate impact caused by Bonava’s operations. By also taking responsibility for its indirect impact, Bonava becomes a real part of the solution for keeping global warming within the Paris Agreement target of 1.5°C and for UN SDG 13 Climate action and its impacts, primarily through targets:

• 13.1 Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries.
• 13.3 Improve education, awareness-raising and human and institutional capacity on climate change mitigation, adaptation, impact reduction and early warning.

Management Approach (GRI 103-2)

Bonava has mapped its climate impact and defined climate targets to be approved by the Science Based Targets initiative in order to ensure scientifically that Bonava sufficiently promotes the limitation of global warming. In accordance with the IPCC’s recommendations for limiting global warming to 1.5°C, Bonava commits to reduce the absolute scope 1 and 2 GHG emissions by 50 per cent, and to reduce the lifetime carbon impact per Bonava home, by reducing the intensity of the corporate scope 3 GHG emissions per production started housing unit, by 50 per cent by 2030 from a 2018 baseline.

Scopes 1–2

In the climate impact mapping, Bonava identified energy suppliers as essential partners in the work to reduce GHG-emissions. A Group level preliminary study has been conducted, and a framework agreement for renewable energy deliveries is under development. Bonava also has operational control over the choice of vehicles in leases for company cars, for example, and a mobility programme is under way to facilitate reduced emissions from motor vehicles.

Scope 3

One example of measures Bonava has taken is to conduct life cycle assessments for optimization of a standardised choice of method for prefabricated concrete frames as part of Bonava’s strategic purchasing. Initially, Bonava will work with its largest – and for its climate impact, most important – suppliers to jointly reduce emissions. In parallel with this work, there is maximum potential for improvements in optimising design and choice of materials, which several of Bonava’s strategic initiatives are cooperating on to achieve full effect.

Bonava complies with the GHG Protocol Corporate Accounting and Reporting Standard as well as the Corporate Value Chain (Scope 3) Accounting and Reporting Standard for measuring and reporting greenhouse gas emissions. Bonava has chosen to apply the operational control approach. The climate impact inventory is based on carbon dioxide equivalents (CO2e). The report is based on invoices, surveyed data, fuel and vehicle registers, and supplier reports. Emissions factors from the UK Department for Environment, Food and Rural Affairs (Defra) and Exiobase v. 3 (exiobase.eu) are used to calculate emissions. The global warming potential (GWP) is based on the IPCC Fourth Assessment Report (AR4) for the next 100 years.

Bonava reports yearly for GRI indicators 395-1,2,3,4 årligen för GRI indikatorerna 305-1,2,3,4 Greenhouse gas emissions scopes 1-3 and Greenhouse gas emissions intensity. Bonava’s detailed climate report is published by public report to Carbon Disclosure Project (CDP).
