Greater impact on Dutch roofs: an ambitious agenda

NextGreen is developing an action plan for the National Rooftop Plan 2020-2023, together with Stroom and Onderstroom. In the plan, the 45 partner government bodies, companies and knowledge institutions emphasize the importance of a multifunctional design for our rooftop landscape, so that we can achieve more impact than the current emphasis on more solar panels on roofs. Our rooftop landscape can also provide solutions for nature, heat stress, flooding, health and the ever-growing demand for space. Read more

Finance sessions Madrid – EU Business & Nature Summit

Banks and investors are increasingly playing a role in halting the loss of biodiversity and ‘bending the curve’ towards the recovery of ecosystems. At the EU Business & Nature Summit (EBNS) in Madrid, NextGreen facilitated two finance sessions, including contributions from ASN Bank, CDC Biodiversité, Triodos Bank Spain, OECD, IUCN, UNEP-WCMC, Global Reporting Initiative, ACCA, Trucost-S&P and CREM.

Factsheets on ensuring climate adaptation in private property

Private property has a very significant role to play in dealing with our changing climate, from extreme rainfall to extended periods of heat and drought. The effects of this can clearly be seen in our cities. Fortunately, there are various policy options that municipalities and water boards can use to incorporate climate-adaption measures into their policy.

From deal to program

During the festive conclusion on the 13th of May, Green Deal Green Roofs presented their results to Delta Commissioner Peter Glas. The forty participating authorities, companies and knowledge organizations celebrated the successes of four years of collaboration. With their ambition for more and better green and blue roofs they listed the measurable effects, mapped out innovations, and wrote the Guide Nature Roofs. They also devoted themselves to financial incentives such as mortgage interest deduction and a more sustainable tax system. NextGreen , together with Stroom en Onderstroom, has guided this collaboration ever since the feasibility phase in 2013.

Celebrate Diversity

‘Celebrate Diversity’, a basic principle for robustness and resilience in nature, has inspired me ever since I got acquainted with the third design principle of Cradle2Cradle during the guidance of the Learning Community C2C in 2010. My current work in the field of biodiversity teaches me about the importance of the diversity of genes and species, and how to reinforce this by connecting areas in order for populations to become more robust due to a bigger gene pool. This ecological principle invites us to celebrate the diversity of perspectives and ideas. Together they make a sustainable transition stronger, as was also confirmed by a recent Workshop Transition perspectives (in Dutch).

Green Roofs present Guide Nature Roofs

On the 28th of March Donné Slangen, Director of Nature at the Ministry of Agriculture, Nature and Food Quality, was issued the Guide Nature Roofs (Handreiking Natuurdaken, in Dutch). This guide deals with roof design, plants, and facilities to help birds, butterflies, bees and other species with food, safety and reproduction. The guide was composed by Green Deal Green Roofs partners, with process management and advice NextGreen.

Pilots Financial incentives for climate adaptation

The impact project ‘Rainwater, tax or reward‘ (Hemelwater belasten of belonen) by the work stream Differentiating Taxes of the Green Deal Green Roofs has developed into the new ‘Alliance financial incentives for climate adaptation’ (Alliantie financiële prikkels voor klimaatadaptatie). This alliance is working together with new partners, in association with the Delta Plan on Spatial Adaptation. The Alliance aims to stimulate citizens and companies to (re)arrange their buildings and gardens in a climate adaptive way and focuses on learning through pilots. This way they seek to further develop these incentives together.

To further research and develop the essential effects of the different financial incentives, the Alliance will carry out pilots with corresponding cross-sectioned working groups. These working groups will engage in collective research subjects and will, if necessary, conduct their own research.

For the period 2019-2020 local authorities have the possibility to receive a financial contribution (Dutch) from the Government to hire expertise to carry out the pilots ‘financial incentives’ (financiële prikkels).

On the 6th of June the Alliance meets up to accentuate the pilots and together define the agenda for the different working groups. Local authorities who are interested can apply by sending an e-mail to info@nextgreen.nl.

The Alliance Financial Incentives for Climate Adaption was preceded by:

Business case, participation and putting Infra Nature out to tender

Biodiversity in the Netherlands has been under pressure for some years now. Because the Netherlands has an extensive and dense infrastructure network, it is especially important to create more biodiversity in this network. Several parties within the Green Deal Infra Nature have studied and exploited this potential. Guidelines on how to integrate biodiversity into tenders, environmental management and business models have been drawn up.

English-language fact sheet Facts&Values

Due to popular demand an English version of the in September published fact sheet ‘Facts&Values Groenblauwe daken’ is now available; fact sheet ‘Facts and Values Green-Blue Roofs’. On the fact sheet you’ll find, among other things, measurable effects on retaining water, the air-purifying function, the energy saving and the noise reduction of green roofs.

Green Deal partners use the fact sheet with info graphic to explain clearly to customers and other interested parties the quantitative benefits of green roofs. NextGreen guided the work stream Facts and Values that put together the fact sheet.

Joint decision model

NextGreen is holding interviews and meetings with experts from the municipality of Amsterdam, Waternet and construction organizations, in order to use the lessons learned from existing projects to guarantee climate adaptation through the use of public-private instruments. These instruments are now being piloted for use in local regeneration projects, urban transformation and change projects throughout the city.

For this new assignment, NextGreen and Stroom & Onderstroom are working with stakeholders to develop an overview of the instruments used and a decision-support tool, including the ‘water-neutral building envelope’, local land use plan and sustainable sewerage levy.

You can read more about this project on the Decision model for public-private instruments project page.
