Act fast but not alone – the role for urban policymakers in delivering a 1.5°C future

A new report translates the key scientific findings and policy observations from the IPCC’s Special Report on Global Warming of 1.5°C (SR1.5) for officials and policymakers of the world’s cities and urban areas. The Summary Report for Urban Policymakers: What the IPCC Special Report on Global Warming of 1.5° Means for Cities was released this week at COP24 in Katowice. While SR1.5 identifies cities and urban areas as one of four critical global systems that can accelerate and upscale climate action; this new summary report provides urban stakeholders access to the most advanced science on why the transition to a 1.5°C world is necessary and how it can be achieved.

In cities and urban areas there are actions that policymakers can take along with residents and stakeholders to help limit warming and adapt to the impacts of climate change. The Summary Report for Urban Policymakers dives deeper into these actions, making sure that ideas are clear for those who could put them into practice. It introduces future pathways, possible impacts, and routes forward; explains why cities matter, including the necessary transitions, technological innovations and lifestyle changes required to meet the 1.5°C target; considers if the urban transition is feasible; details how the urban transition can be enabled, as through policies and engagement; and looks into how to pay for it.

The conclusion is that an opportunity exists for urban policymakers to play a key role in adapting to and driving solutions to climate change, but fast action must take place over the next two decades, and urban policymakers cannot do it alone. All sections and levels of government must work in an integrated way to allow for the urban transition required to limit warming to 1.5°C. Action at the city, state, and regional levels is specifically recommended for urban energy systems, buildings, transport and urban planning, green infrastructure, sustainable land use, and water management; co-benefits of improved public health and reduced air pollution are also highlighted.

The report was released along with an open letter to urban policymakers, written by a group of ten sustainability-focused city-networks, associations and non-governmental organizations and international organizations.



Women of science and action to tackle climate change: signs of progress but still a long way to go

Data show the role of women is still limited in climate research and international climate institutions. However, initiatives are increasing to make decision-making processes more inclusive and gender-responsive.


What is the state of the European climate?

What does it mean to be the world’s fastest warming continent toppling flooding, temperature and wildfire records as glaciers melt at unprecedented rates and communities suffer like never before? Understanding the latest trends in Europe’s climate, including progress in areas such as renewable energy generation and resilience to extreme events, is the key to effective adaptation and mitigation.

A single policy change, two major solutions: how switching from subsidizing fossil fuel to pricing CO2 emissions will fight climate change and promote sustainable development

From subsidizing fossil fuel to pricing CO2 emissions: reversing the policy as a solution to fight climate change and promote sustainable development

A new study claims that fossil fuel subsidies are a burden for national budget and for the environment. Carbon pricing should be introduced, instead, as a solution to drastically reduce CO2 emissions and obtain financial resources to address sustainable development.
