The aim of this research is to assess the potential impact of the CO2 Performance Ladder on CO2 emission reduction. The CO2 Performance Ladder is a new green procurement scheme that has been adopted by several public authorities in the Netherlands; it is a staged certification scheme for energy and CO2 management. The achieved certification level gives companies a certain competitive advantage in contract awarding procedures. While the scheme has been widely adopted by companies in the construction industry, other types of companies in the supply chain of the commissioning parties also participate. Currently, more than 190 companies participate in the scheme. The aggregate CO2 emissions covered by the scheme are around 1.7 Mtonnes, which corresponds to almost 1 % of national greenhouse gas emissions in the Netherlands. Since the introduction of the scheme the total CO2 emissions have decreased substantially. Nevertheless, these emission reductions should be interpreted with caution since emission reductions are dominated by a few companies and are affected to a large extent by economic activity. Companies participating in the scheme have set different types of CO2 emission reduction targets with varying ambition levels. The projected impact of these targets on CO2 emissions is in the range of a 0.5 %-1.3 % absolute emission reduction per year, with a most likely value of 1.1 %. The CO2 Performance Ladder can therefore make a substantial contribution to achieving the CO2 emission reductions for non-ETS sectors in the Netherlands up to 2020.

Nederland heeft de doelstelling om in 2050 klimaatneutraal zijn. Dit staat ook hoog op de agenda in het bedrijfsleven en bij consumenten maar vereist grote inspanning. Bedrijven kunnen een belangrijke rol spelen in het verlagen van de CO2-uitstoot van consumenten. Er zijn diverse initiatieven die bedrijven kunnen nemen om consumenten bewust te maken van hun CO2-uitstoot, maar ze moeten die ook accepteren. Welke initiatieven zullen de consumenten omarmen en welke niet? Welke consumenten gaan het verschil maken?

n the work package described in this report, members are investigating whether a cooperative of farmers can become self-sufficient in energy and fertilization by using manure and organic waste flows in combination with anaerobic fermentation. The aim is to link the nutrient cycle (from manure to digestate to green fertilizer consisting of, for example, nitrate, phosphate, potassium, and trace elements) to a self-sufficient energy system, by the combined production of electricity, green gas, green fuels, and green fertilizers. Within this research such a system is called a circular multi commodity system (CMCS). In effect linking, the nutrient cycle with an energy production chain. In addition, other energy sources and sinks can also play a role in the system such as wind, solar PV and storage (e.g. batteries or hydrogen). For this symbiosis of production techniques to succeed in practice, intensive cooperation between arable farmers and dairy farmers is needed. Farmers supply part of the input from the biofermenter and receive green fertilizers at the end of the process, which are used as a substitute for fertilizer. The case is based on a cooperative of farmers with a minimal geographical spread and maximum diversity in type of business. In this way, the current waste and nutrient chain is being replaced by a more sustainable and closed cycle. This could provide significant environmental benefits: reduction of the environmental impact through the use of fertilizer, reduction of dependence on fossil raw materials, and reduction of CO2 emissions.
