The world is currently responding to the climate crisis and the nature crisis as if they were separate challenges. This is a dangerous mistake. The are leading to dire impacts for our health

Target audience
The World Health Association; National agencies for climate; National agencies for biodiversity; Health professionals, at all levels; Political leaders.
The problem
Many commitments made at the Convention on Biological Diversity internation meetings have not been met. This has allowed ecosystems to be pushed to the brink, greatly increasing the risk of arriving at ‘tipping points’, abrupt breakdowns in the functioning of nature. If these events were to occur, the impacts on health would be globally catastrophic.
What we did and why
We reviewed the twin climate and nature crises under the pre-conditions for WHO to declare a situation to be a Public Health Emergency of International Concern. These are are that it:
1) is serious, sudden, unusual or unexpected;
2) carries implications for public health beyond the affected State’s national bor- der; and
3) may require immediate international action.
Our study’s contribution
Climate change would appear to fulfil all the conditions for a global health emergency. While the accelerating climate change and loss of biodiversity are not sudden or unexpected, they are certainly serious and unusual.
As such the level of risk, combined with the severe impacts on health already occurring, means that the World Health Organization should declare the indivisible climate and nature crisis as a global health emergency.
Impacts for city policy and practice
First, we must recognise this crisis for what it is: a global health emergency. With regard to this, we strongly advocate that:
WHO declare this situation to be a Public Health Emergency of International Concern.
National agencies ensure better integration of national climate plans with biodiversity equivalents.
Health professionals, at all levels, be powerful advocates for both restoring biodiversity and tackling climate change for the good of health.
Political leaders recognise both the severe threats to health from the planetary crisis as well as the global and local benefits that can flow to health from tackling the crisis.

Evidence overwhelmingly suggests that the built environment has an impact on people’s health, particularly in terms of noncommunicable diseases such as asthma, diabetes and poor mental health. However, health is rarely prioritised in urban planning decisions at present, and earlier work by this research group has shown that senior decision-makers feel they lack the power to influence planning and policy decisions in order to improve the situation. This intervention area adds to the wider research programme, which is focused primarily on the delivery of quantifiable socio-environmental and health economics valuations. People make decisions not just based on economic valuation, so an understanding of why people make decisions and how those decisions can change is essential. This paper describes the methodology that will be used to develop this intervention. Findings will be published later.
