Renaturing our cities for climate action and citizens’ wellbeing – Open letter to the EU Commission

Boosting the uptake of green infrastructure through new EU rules on buildings’ energy performance can lead the way for decarbonised, healthier and more biodiverse buildings and cities, 36 organisations representing industry associations, companies, universities, think tanks and NGOs, wrote in an open letter to the European Commission. “The built environment is a core area of the Union’s decarbonisation efforts in the next ten years. We believe that green infrastructure, with the support of the right legislative framework, can play a key role both for climate mitigation and in supporting urban areas to adapt to a changing climate”, write the co-signatories. They underline that with urban population projected to further grow in most European regions, investing in the switch from grey to Blue-Green Infrastructure must be a priority to renature our cities, reduce their carbon footprint and improve the health and wellbeing of their residents. The 36 organisations call on the Commission to introduce in its proposal for the revision of the Energy Performance of Buildings Directive (EPBD) mandatory provisions for the integration of green infrastructure in new and renovated buildings. In particular, they recommend to: Systematically integrate green infrastructure in a new Zero Emission Building standard and require combination with solar renewables installations (bio-solar roofs) such as solar thermal and/or photovoltaic energy; Require commercial and public buildings, undertaking renovations, to install green roofs and walls in combination with solar renewables installations (bio-solar roofs) such as solar thermal and/or photovoltaic energy; Require Member States to provide incentives for large residential buildings occupying a land surface of 400m2, and more, and undertaking renovations to install green roofs in combination with solar renewables installations (bio-solar roofs) such as solar thermal and/or photovoltaic energy. European citizens will support these actions, as the recent lockdowns stressed the importance of access to nature and green spaces for people’s mental and physical health and general wellbeing, the letter states. With the right legislative framework, we can make nature and green areas accessible to all by installing vegetation on billions of square meters of roofs and impervious surfaces which would be otherwise unused.

Why greening cities should be a pillar of climate action

Rotterdam, The Netherlands: section of the Dakakker. ID:1415339051 By interweaving green infrastructure with the built environment, we can tackle some of the effects of human-induced warming locally, writes Luigi Petito, Head of WGIN EU Chapter, in the Autumn edition of Living Architecture Monitor This summer’s extreme weather conditions battered most of Europe. In the North of the continent heavy precipitations devastated large part of Belgium and Germany. This had a dramatic human impact. In the South, wildfires ravaged large areas in Spain, Italy and Greece. Sadly, these events were not limited to Europe: extreme weather was a phenomenon witnessed by communities across the globe, showing that even some of the world’s richest countries remain unprepared for the intensifying consequences of climate change. The Sixth Assessment Report of the United Nations Intergovernmental Panel on Climate Change reminded us that unless significant reductions in CO2 and other greenhouse gas emissions occur in the coming decades, the global temperature will increase  above 1.5 °C and the consequences for the health of planet Earth and for humanity will be dire. Regrettably, many changes due to past and future greenhouse gas emissions are irreversible, especially changes to the ocean, ice sheets and the global sea levels. Others can be addressed with effective mitigation and adaptation actions. In cities for example, we can reverse the trends if we renature urban areas. By interweaving green infrastructure with the built environment, we can tackle some of the effects of human-induced warming locally. At the same time, we can limit further urbanization, which, according to the IPCC report, will increase the severity of heatwaves as well as mean and heavy precipitation and resulting runoff intensity.

In the press | Rainwater as a resource in the city

Blue-green infrastructure are key to help adapt urban rainwater management to climate change, reports Tagesspiegel Background (Germany). In Germany and the EU, experts are calling for more commitment to adapting urban rainwater management to climate change. The focus is on new concepts such as a blue-green infrastructure and the networking of storage measures. Luigi Petito, Head of the European Chapter of the World Green Infrastructure Network, was asked by Tagesspiegel about the benefits of green infrastructure for urban water management and the latest policy developments at EU level. “A lot is happening right now, but there is still a lack of mandatory regulations for blue-green infrastructure in cities,” Petito said, pointing in particular at the upcoming revision of the EU Urban Waste Water Treatment Directive (UWWTD). “Germany has played a pioneering role in the implementation of blue-green implementation of blue-green pilot projects in cities, but also in the development of technical solutions”, he added. Such examples could serve as a model throughout Europe. Read the full article (German)

Have Your Say: European Commission Consults on New Stormwater Policies

Oblique lid of a well after thunder shower. ID: 697109167 April 2021 was the wettest and coldest April on record, yet summer in Europe could not have had a better start for green infrastructure. Let’s find out why. In the Summer edition of Living Architecture Monitor (LAM), Head of EU World Green Infrastructure Network Luigi Petito, writes about the Urban Waste Water Treatment Directive (UWWTD) that was developed 30 years ago to ensure clean and safe urban wastewater in European cities. The full article is available here. The LAM magazine is a quarterly publication first published in 1998.  It features in-depth interviews with leaders in the green building movement, opinions, research, and green roof and wall project profiles. Living architecture is the integration of living, organic systems with non-living, inorganic systems in, on, or around buildings. Living architecture is an important step to reconcile people and nature in the modern built environment.

In the press | Jure Šumi: “Green infrastructure bring life to cities”

Azotea del Instituto Nacional de Biologia, en Liubliana, capital de Eslovenia. © DANILO BEVK In an interview to top-ranking Spanish media outlet El Pais, Jure Sumi, president of the Slovenian Green Infrastructure Association and Representative of the WGIN European Business Group presented the multiple benefits of nature in cities. “The holistic benefits that urban green infrastructure is bringing to cities are relatively little known”, Jure Sumi told El Pais, “People, and even city officials, are not aware of all the positive effects of nature. The benefits go beyond the aesthetic. Green infrastructure brings life to cities, reduces overheating in city centres, manages stormwater and removes dangerous dust particles from the air…. If buildings are designed correctly, green roofs on top can be additional amenity spaces for residents to enjoy nature at home.” “Not understanding all the benefits brings us to the second challenge”, he explained, “Adding green infrastructure is costly. As the benefits are not yet recognised, investors are not willing to pay much more for ‘green buildings’ as they are not sure how to sell the benefit to potential buyers. They see green infrastructure more as an additional cost than as an opportunity to increase the value of the building. I firmly believe that this is our task, to convince national and municipal governments, as well as investors and residents, to understand the benefits of green infrastructure. In the end everyone wins: municipality, investor, resident and, above all, nature.” Read the full article (in Spanish): https://elpais.com/elpais/2021/06/14/seres_urbanos/1623663219_703877.html

Multiple benefits of green roofs recognised in EU climate adaptation strategy

On 24 February, the European Commission adopted a new EU Strategy on Adaptation to Climate Change, setting out the pathway to prepare for the unavoidable impacts of climate change. Green roofs and walls feature prominently in the strategy, which fully recognises their multiple benefits for climate adaptation. “Blue-green (as opposed to grey) infrastructures are multipurpose, ‘no regret’ solutions and simultaneously provide environmental, social and economic benefits and help build climate resilience”, it is stated in the document, which adds “Europe needs to leverage more investments in nature-based solutions to generate gains for adaptation, mitigation, disaster risk reduction, biodiversity, and health”. The strategy mentions the deployment of nature-based solutions for adaptation among the Commission’s priorities to make adaptation actions “systemic” across the Union, together with integrating adaptation into macro-fiscal policy and local adaptation action. Moreover, the Commission called for strengthened action to “prepare Europe’s building stock to withstand the impacts of climate change”, highlighting that green roofs and walls are key to make sure that “buildings can also contribute to large-scale adaptation, for example through local water retention that reduces the urban heat island effect.” The Commission announced it will support the integration of climate resilience considerations into the criteria applicable to construction and renovation of buildings and critical infrastructure. “The Commission’s recognition of the benefits of green roofs and walls to help make Europe resilient to climate change is excellent news for citizens and the environment. We very much welcome this approach and we hope this will serve as inspiration to governments and local administrations around the world. Green roofs and walls can greatly support climate adaptation efforts and as WGIN we are ready to do our part,” said Prof. Manfred Koehler, President of the World Green Infrastructure Network (WGIN). About us The EU Chapter of the World Green Infrastructure Network (WGIN) aims to increase the awareness of European Union policymakers about the multiple benefits of green infrastructure, with a specific focus on Building Integrated Vegetative Systems (green roofs and living walls). WGIN brings together national and regional industry associations to promote the development of the green infrastructure industry through training, research, advocacy for new policy, conferences, publications, and promotion.
