Many cities try to mitigate the extreme heat by planting trees. But the cooling achieved by such programs is debated, as previous analyzes focus on much smaller scales than the city-wide ones planners are working on. To fill this gap, we performed a scaling analysis of cooling efficiency (CE)—the temperature reduction associated with the 1% growing tree canopy (UTC)—to predict citywide CE. The results show that CE increased with increasing spatial scales in a convex power form. The power law was consistently found across multiple cities with different climate contexts and was also robust under different summer weather conditions within the city. Power-law scaling of CE can provide a tool for urban planners to set UTC targets for extreme heat mitigation. (Jia Wang, Weiqi Zhou, Steward TA Pickett , more at pnas.org)

The Commission provided today more than EUR 380 million per 133 new projects throughout Europe as part of the LIFE program for the environment and climate. The allocated amount represents more than half of the total €574 million investment needs for these projects – the rest comes from national, regional and local governments, public-private partnerships, businesses and civil society organisations.

Climate change poses a significant risk to urban areas worldwide, exacerbating existing vulnerabilities and threatening the well-being of millions of people. This proposal outlines a comprehensive plan for the implementation of climate change adaptation strategies aimed at increasing the resilience of cities. By focusing on infrastructure improvements, community engagement and sustainable practices, the initiative will equip cities to better withstand climate impacts such as floods, heat waves and resource scarcity. Through joint efforts with local stakeholders, we aim to create a model for sustainable urban adaptation that can be replicated in other regions. (More on fundsforngos.org)

Seven of the most common forest trees in Europe have been shown to be able to protect their genetic diversity against major changes in environmental conditions. This is despite the fact that their ranges have shrunk and the number of trees has plummeted during ice age cycles. This is according to a study by a European consortium led by the universities of Uppsala and Helsinki, published in Nature Communications (Words: Uppsala University).

"This is very positive from a biodiversity point of view, because these trees are keystone species on which many other species depend," says Pascal Milesi, associate professor of plant ecology and evolution at Uppsala University and first author of the study.

The researchers focused on examining how the genetic diversity of tree species was affected by ice age cycles. The trees survived both warm and cold periods. During the last ice age, about 10,000 years ago, the range of trees was greatly reduced. Scientists therefore thought that genetic diversity would be low. However, it turned out to be just the opposite – the species had a high genetic diversity and was thus resistant to drastic changes in its habitat. (More on envirotecmagazine.com)

In September, the European Commission held a high-level round table on how to manage climate risks and damages, including taking into account vulnerable groups in society. Participants called for bold action on climate resilience and discussed structural changes, applicable tools and financing for the future. The round table provided an opportunity for an exchange of views ahead of the preparation of the European Climate Change Adaptation Plan. (More on climate.ec.europa.eu)

The National Action Plan (NAP) identifies the residential environment as one of seven key areas of focus for climate change adaptation. The main goal in this area is to create a high-quality legislative, institutional, professional and financial environment for systematic and complex actions of local governments in the process of adaptation to climate change in cities and towns.

The NAP focuses on the following key areas of adaptation measures in the residential environment:

• Legislation and planning:
  • Incorporating adaptation into legislation: The current legislation does not sufficiently take into account the issue of adaptation to climate change, which makes it difficult for cities and municipalities to implement the necessary adaptation measures.
  • Integrating climate change into planning documents: Planning documents should contain a comprehensive response to climate change, which requires their climate assessment and the creation of a separate adaptation strategy for each location.
• Methodological and professional support:
  • Creation of methodologies: In Slovakia, there is a lack of formalized methodologies for assessing the vulnerability of settlements, preparing adaptation strategies and evaluating their effectiveness.
  • Introduction of the professional support mechanism: Cities and municipalities often do not have sufficient professional capacity to implement a complex adaptation process. Therefore, it is necessary to create a professional support system that will provide them with the necessary information and expertise.
• Education and awareness:
  • Public administration education: It is important to ensure the training of municipal and state administration workers in the field of adaptation to climate change.
  • Public involvement: Increasing public awareness of the issue of climate change and adaptation is key to the successful implementation of adaptation measures.
• Funding:
  • Securing financial resources: Implementation of adaptation measures requires significant financial resources. It is necessary to ensure their availability from various sources, including the state budget, European funds and private investments.
  • Creation of motivational mechanisms: For municipalities, it is necessary to create motivational mechanisms that will support them in investing in adaptation measures, for example through co-financing from EU funds.

NAP emphasizes that adaptation of settlements to climate change is a complex process that requires cooperation and coordination between the state administration, local government, the business sector, the academic community and the public.

In addition to the mentioned areas, the NAP also focuses on specific adaptation measures in settlements, such as:

• Retention of water in the country and in settlements: Improving water management in order to mitigate the negative impacts of drought and floods.
• Reducing urban overheating: Support for building green and blue infrastructure, adaptation of buildings and public spaces.
• Improving infrastructure resilience: Ensuring the resistance of critical infrastructure (transport, energy, water management) to extreme weather conditions.
• Improving population health protection: Ensuring sufficient awareness of the health risks associated with climate change and the implementation of preventive measures. (Co2AI)

Priorities of financing adaptation measures in the residential environment. The document "Action Plan for the Implementation of the Slovakia's Climate Change Adaptation Strategy" places great emphasis on the adaptation of settlements to climate change and identifies several important funding priorities in this area:

1. Legislative and strategic preparation:

• Funding of audits and analyzes of existing legislation with the aim of identifying obstacles to the implementation of adaptation measures in settlements and proposing the necessary changes.
• Support for incorporating the issue of climate change into spatial plans and other strategic documents of cities and municipalities.
• Creation and updating of methodologies for assessing the vulnerability of settlements to climate change and for the creation of adaptation strategies.

2. Capacity building and professional support:

• Creation of a professional support system for cities and municipalities in the adaptation process, including provision of information, consultations and capacity building.
• Education and training for public administration workers at all levels on the issue of adaptation to climate change.

3. Specific adaptation measures:

• Flood risk mitigation: Investments in flood protection, building elements of green and blue infrastructure in cities with the aim of retaining water in the country.
• Fight against urban overheating: Support for the construction of green infrastructure, adaptation of buildings and public spaces in order to reduce the effect of urban heat islands.
• Ensuring the availability of water resources: Investments in the protection and effective management of water resources, support for water retention measures in settlements.
• Increasing infrastructure resilience: Adaptation of existing and planning of new infrastructure (transport, energy, water management) with regard to climate change.

4. Social inclusion and support of vulnerable groups:

• Identification and support of measures to mitigate the negative impacts of climate change on socially vulnerable groups of the population.

Funding sources:

The document emphasizes the importance multi-source financing adaptation measures in settlements, using a combination of:

• State budget:
• Local government budgets:
• European Structural and Investment Funds (ESIF):
• Common Agricultural Policy (CAP):
• Additional resources (e.g. Environmental Fund, LIFE program, EEA and Norway grants):

It is important to ensure that adaptation to climate change becomes a priority in the allocation of funds from all relevant sources. Resources should be allocated based on clear criteria, with an emphasis on efficiency and sustainability of investments.

The document emphasizes that financing adaptation in the residential environment is a long-term investment that will not only reduce the risks and damages caused by climate change, but also improve the quality of life in cities and towns. (Co2AI)

Half of the world's population currently lives in cities, and this proportion is expected to rise to 70 % by 2050. Due to large populations, a lack of green spaces that can mitigate warming, and an aging infrastructure that is vulnerable to flooding and extreme weather , the world's cities are not prepared for climate change.

Proactive measures are needed to make cities more resilient to climate change and able to protect community health, according to a new report from the Yale School of Public Health (YSPH), Resilient Cities Network and The Rockefeller Foundation. (Andrei Ionescu, more at earth.com)

Whether selecting actions for your SECAP or prioritizing investments within budget constraints, SYNERGISE+ guides cities through a structured and flexible decision-making process.

Although SYNERGISE+ is intended for signatories to the Convention, it is also valuable for other entities such as energy agencies or businesses working on local sustainability projects. The tool allows users to select actions relevant to their specific sector, making it applicable to a wide range of urban and local adaptation and mitigation efforts. (More on eu-mayors.ec.europa.eu)

The EEA report "Tackling the environmental and climate footprint of buildings" assesses the current state of Europe's building stock and explores what is needed to make European buildings more sustainable. Renovating existing buildings using sustainable materials while improving resilience to climate change and working with nature are key. The report also examines what policy measures are needed to achieve this goal by 2050.

More than 30 % of the EU's environmental footprint comes from buildings, making them the sector with the largest environmental impact. Approximately one third of the Union's material consumption goes to the construction industry. The use of buildings represents 42 % of total energy consumption and 35 % of greenhouse gas emissions. The decommissioning of buildings leads to the largest mass flow of waste in the EU. Although the recycling rate of demolition waste is high, it mainly results in low value, the EEA report says.

During the last two years, a group of stakeholders established at the initiative of the European Commission has been meeting as part of the dialogue on climate resilience. It aimed to discuss ways to reduce the climate protection gap – the gap between economic losses and insurance losses from the materialization of climate-related risks – and increase the resilience of economies and societies to the effects of climate change.

The dialogue provided a safe space for an open exchange of views between stakeholders including public authorities, regulators, consumer organizations and the insurance industry on ways to address this climate protection gap and increase climate resilience in the EU with a focus on climate change adaptation.

The EU Covenant of Mayors has been an active participant in this dialogue and has ensured that the perspectives, challenges, best practices and experiences of local authorities are taken into account in the discussions and actions proposed in the final report. (More on eu-mayors.ec.europa.eu)

This summer, the Mission Implementation Platform (MIP4Adapt) completed its first mutual learning program for the signatories of the EU Climate Change Adaptation Mission Charter.

After the successful first program, the second Peer Learning program will run from October 2024 to February 2025. Registration is open and ends on September 29, with the initial meetings taking place in October.

Highlights from the first peer learning program

15 charter signatories attended the program to learn from experts, share knowledge and best practices, and share challenges or questions with their colleagues to improve their adaptation work.

A key element of the program was the involvement of the charter signatories in the program from the beginning. Each group decided on specific topics and areas of focus in order to maximize the benefits of the program for charter signatories and tailor the content to their specific needs.

Three peer learning groups were created:

• Nature-based solutions focused on adaptation initiatives for water management and urban and agricultural environments.
• The selection and implementation of adaptation measures was linked to the Regional Adaptation Support Tool (RAST) and helped participants select, prioritize and finance their adaptation solutions.
• Citizen and stakeholder engagement focused on organizing citizen assemblies on climate change to engage stakeholders in their adaptation efforts.

During all 10 meetings, adaptation experts from MIP4Adapt and other mission projects provided expertise on each of the topics, along with introducing various guides, tools, funding and general support methods that charter signatories can use. These expert presentations were followed by detailed discussions among the charter signatories in which they shared their best practices, successes, challenges and questions with the wider group.

Charter signatories also worked on live exercises in their groups to show how the tools introduced by the experts would work in practice. These practical examples allowed participants to see how they could implement the tools in their own adaptation initiatives. (Co2AI)

Europe's pursuit of competitiveness and security should not replace a long-term vision that brings benefits to citizens and well-being. The European Council's "strategic agenda" published in June said the EU's mandate for the next five years would focus on competitiveness and security. This vision is understandable if the goal is to convince European citizens and economic players that the EU can provide protection and strength in times of geopolitical and economic turbulence.

However, the pursuit of competitiveness and security should not replace the political project and long-term vision of a Europe that brings citizens and well-being – and the goals of social and environmental sustainability should return to the political debate.

European Commission President Ursula von der Leyen appears to have reflected on this need in her political guidelines presented to the European Parliament in July. While she made it clear that competitiveness would be a key priority of the Clean Industry Deal - which will replace the European Green Deal - she said the Commission would "significantly increase its funding for Just Transition in the next long-term budget".

Cities are the engine houses of climate change – they consume 65 % of the planet's energy and produce 70 % of greenhouse gas emissions responsible for warming the planet. And they are often one of its biggest victims: residents drown in dense concrete environments due to the "heat island effect".

Urban populations are expected to double by 2050, meaning cities' climate footprint could increase unless the way we plan, power and move around them changes. (Holly Young, more at dw.com)
