Hearing on climate assessment of building materials

natureplus is introducing a new method for assessing climate compatibility. The public consultation on the relevant guideline will take place on 24 October.

In order to check its high holistic quality standards for the building products to be awarded, natureplus uses various methods and criteria for the natureplus eco-label. An important instrument for the evaluation of products was and is for natureplus the life cycle assessment as an internationally standardised method to analyse and quantify the emissions to air, water and soil, the resources consumed and the associated environmental and health consequences. As a result of this analysis, most recently regulated for building products in EN 15804, a large number of environmental indicators are available which make a correct and fair assessment of the products increasingly complex and thus more difficult and expensive. However, within the framework of an ecological product assessment it is of central importance to rely on consistent and reliable data and methods.

Concentration on GWP and PE proposed

Experts largely agree that coping with anthropogenic climate change is currently mankind's greatest challenge and that the production of building materials in 2010 contributed significantly to climate change with around 18.4% of industry-related CO2 emissions. In accordance with EU environmental and climate policy, natureplus will therefore concentrate in future on the environmental parameters of global warming potential (GWP) and primary energy (PEI) in its life cycle analysis. The products awarded with the natureplus quality seal must comply with strict limits for these two robust indicators, which keeps the test compact and allows better communication of the results. The aim is to improve the climate compatibility of building materials, measured in terms of their CO2 footprint (CFP), and energy efficiency in the production of building materials by introducing limit values for these two parameters.

New Award Guideline RL 5020

Against this background, the Criteria Commission of natureplus has drawn up a new Award Guideline 5020, which describes the choice of environmental indicators, the methods for determining limit values and the procedure for determining and evaluating the climate compatibility and energy efficiency of building products. This new directive, which in future is to become the basis for the award of the natureplus eco-label, will now be presented to interested parties for comment in a public hearing. The concerns and suggestions expressed during the hearing will then be incorporated into the final version of the 5020 Award Guideline, which is to be adopted at the end of 2019.

Hearing on 24 October

The hearing will take place on Thursday, 24 October from 14:30 to 17:00 at the KaEins Conference Centre in Frankfurt/M, Kasseler Str. 1a. The hearing is open to all interested parties, but first and foremost to natureplus members and associations and initiatives dedicated to sustainable building with climate-friendly building materials. Written comments can also be submitted to the hearing. A registration under the address is necessary. The necessary documents - in particular the draft guideline 5020 - will be sent with the confirmation of the registration.
