The report provides up-to-date information for policymakers on the how to apply nature-based solutions for climate change adaptation and disaster risk reduction and at the same time making use of multiple societal benefits that these solutions can bring. Drawing on selected examples across Europe, the report shows how impacts of extreme weather and climate-related events are already tackled in this way. It also assesses global and European policies and how nature-based solutions are increasingly being integrated in the efforts to shift towards sustainable development.

The EU has raised its climate target for 2030 to at least -55 %. Agora Energiewende and Ecologic Institute sketch a "Fit for 55" package that can ensure both environmental integrity and solidarity. It investigates four options how to regulate heating and transport emissions, focusing in particular on the pros and cons of expanding emissions trading to these sectors. The paper makes the case for a smart mix of EU-level carbon pricing and companion polices.

Tenant electricity systems generate solar power on apartment buildings and deliver it directly to the households in the building. In a new study, Katharina Umpfenbach and Ricarda Faber (Ecologic Institute) evaluate the effects of the existing tenant electricity systems in Berlin. The bottom line: Berlin's 74 tenant electricity projects have positive ecological and socio-economic effects, but these remain low compared to the technically available potential. Currently, only 1 % of the tenant electricity potential is used. The study is available for download.

As part of the CiBER project "Circular City Berlin - pathways from potential to implementation", initiatives and business models are being investigated that can contribute to the development of a next-generation circular economy in Berlin. The special focus is on the areas of construction, electronics and textiles. The next-generation circular economy is about innovations in product design and product use systems.

Das Innovationsfeld Bauen ist ein ressourcenrelevantes Feld in Berlin. Kreislaufwirtschaftsansätze im Bereich Bauen müssen entlang des Lebenszyklus ansetzen: vom Design langlebiger und rückbaufähiger Strukturen über die Nutzungsphase und die materialerhaltende Nachnutzung bis hin zu zirkulären Geschäftsmodellen.

As part of its work within the ETC-ICM, Ecologic Institute has contributed as lead author to a new European Environment Agency (EEA) report examining the multiple pressures that agriculture put on Europe's water. The report shows that that a wider uptake of sustainable agricultural practices such as organic farming, agroecological approaches and nature-based solutions is necessary to protect the water environment. To achieve this, ambitious measures to promote sustainable agriculture must be adopted in the upcoming EU common agricultural policy 2021-2027.

To achieve the turnaround towards carbon neutrality, countries around the world need to take much more ambitious action in this decade. One of the key fields of action is the transition of the energy sector –from fossil to renewable fuels, while drastically reducing energy consumption. This paper discusses options how such action can be enhanced through multilateral cooperation.

This paper provides three recommendations to improve the public acceptance of bio-based products and processes. These recommendations are accompanied by concrete actions and good practice examples, based on stakeholder feedback received during the BIOBRIDGES project (2018-2020), relevant results of other EU-funded projects, as well as the results of a targeted literature review.

Diffuse pollution is one of the key reasons European water bodies are failing to meet environmental objectives as specified in the EU Water Framework Directive (WFD). Outbreaks of toxic green algae affect rivers, lakes and coastal waters creating so-called "dead zones" where no aquatic life can thrive. Such outbreaks are by-products of dangerously increasing nutrient levels in water. Nutrient and soil losses have been recognised as challenges for decades across Europe and have been a key driver for freshwater biodiversity losses. With climate change, these challenges are likely to get worse: higher temperatures, lower river flows and more frequent and more violent flooding events. Other human-induced changes (such as dams and weirs) have modified the course of rivers and affected their natural flows.

Modernising the EU's building stock is essential to meet the twin goals of climate action and green recovery. The building sector is responsible for 27 % of total greenhouse gas (GHG) emissions and for 36 % of energy-related GHG emissions when considering direct and indirect GHG emissions. According to the European Commission, building renovation rates must double to contribute to the envisioned 55 % emission reduction by 2030 – and this in turn is vital to go climate neutral by 2050.

The European Environmental Agency (EEA) published their landmark report on the state of nature in the EU on 19 October 2020, representing the most comprehensive assessment of the status of European nature and biodiversity to date. The State of Nature 2020 provides invaluable insights about the impact of conservation measures that have been applied as well as remaining gaps. The findings indicate that the majority of Europe's biodiversity continues to decline at an alarming rate, threatening the survival of thousands of animal species and habitats.

Nature-based solutions (NBS) are emerging as a tool to integrate nature into territorial planning, with great opportunities to address these threats and benefit humans and ecosystems in parallel. The guide for integrating nature-based solutions in urban planning, a first approach for Colombia has been developed to facilitate the inclusion of nature in urban planning through a seven-step process. The guide was written by Carolina Figueroa during her time at Ecologic Institute as an Alexander von Humboldt International Climate Protection Fellow. The guide is available for download.

Nature-based solutions (NBS) are solutions that are inspired and supported by nature. They can be used in urban settings to complement or replace "traditional" or "grey" solutions to social and environmental challenges, such as air pollution, the heat island effect, water scarcity, flooding, loss of nature and lack of social cohesion. This guidance document highlights a range of policy and supporting instruments relevant for NBS design, implementation and maintenance.

Achieving the Paris Agreement Long-term temperature goal (PA LTTG) requires closing the 2030 ambition and action gap between emissions levels consistent with the Paris Agreement and emissions levels projected with current targets and policies. G20 countries have a crucial role to play in realising increased climate policy ambition, given their economic power and prosperity, as well as their influence on investments, technology deployment and financial flows. This briefing paper provides an overview of mitigation options that have been analysed in recent literature and that can contribute to closing the emissions gap in 2030. This provides the basis to identify key policy areas and promising options for intergovernmental cooperation between the G20 nations, as well as possibly other relevant actors.
