Climate Change: The IDN perspective

The global average surface temperature of the Earth has increased by approximately 0.7°C over the last 100 years (1906 – 2005): man-made emissions of greenhouse gases particularly carbon dioxide are very likely the principal cause (IPCC, 2014). Global temperature rises of up to 4°C are projected for the next 100 years with knock-on effects on extreme events such as storms, sea level rise, droughts and increased levels of precipitation The impacts on ecosystems and societies could be devastating.

Climate change is a global problem; there is a need to share knowledge, technologies and expertise between different countries and regions. It also poses a professional challenge to all planners which prompted changes to the RTPI Vision for Planning. The RTPI launched its seven commitments on "Planning to Live with Climate Change" at the Planning Convention in June 2009.

The IDN has a key to play in disseminating knowledge about planning approaches to climate change, promoting and sharing good practice and policy, and influencing decision makers.

An international perspective on planning and climate change

All countries – regardless of their level of development – need a spatially coherent approach to climate change mitigation and adaptation. This should be set within a broader context of sustainable development as important links exist between planning for climate change and wider sustainability concerns such as biodiversity protection, water conservation and minimisation of resource consumption (e.g. using green roofs for urban cooling and runoff reduction whilst also enhancing biodiversity). As the IPCC (2007) states: "Sustainable development can reduce vulnerability to climate change, and climate change could impede nations' abilities to achieve sustainable development pathways."

Those countries with the highest total historical carbon emissions, such as the UK, could be argued to have a particular moral imperative to act on climate change mitigation and to lead the way.

With regard to climate change adaptation, the need and type of response will vary by country and region; however, it is important to recognise that many of the world's poorest people living in countries in the global south are projected to be particularly vulnerable to climate change impacts, such as floods and drought. They will need support to adapt, and given the 'polluter pays principle', there is arguably again a moral imperative on the largest polluting countries to assist.

Sustainable Development Goals (SDGs)

In 2015, world leaders from over all 193 UN countries adopted the 2030 Agenda for Sustainable Development, with a new set of 17 Sustainable Development Goals replacing the former Millennium Development Goals (MDGs) which were introduced in 2000. These 17 SDGs aim to end poverty, fight inequality and injustice, and tackle climate change by 2030.

COP21

In 2015, the United Nations Climate Change Conference (known as COP21) consented to the Paris Agreement, a new international agreement on tackling greenhouse gas emissions from 2020. The key commitment was to keep global warming below 2 degrees Celsius compared to pre-industrial levels, with an attempt to limit the global temperature rise to 1.5 degrees Celsius. Further pledges included the review of each countries contributions to emissions reductions every five years and the provision of 'climate finance' to provide developing countries with funds for climate change adaptation and renewable energy.

What else is the RTPI doing on climate change?

You can follow our activities elsewhere on the RTPI website e.g. the main Climate Change page which has links to guidance, advice and examples of best practice; and the research page which links to projects, publications and events. We would always be glad of links to sources of advice that you have found useful, or case studies that demonstrate good practice, either your own, or from the work of others. To add an item, please email our Policy & Practice staff.
