Climate Change is a Health Emergency.

Climate,Health, and Equity in All Policies

Opportunities for Action

39

Consider climate, health, and equity impacts of all legislation Support AB32: full implementation of cap-and-trade; strong 2030

targets

Oppose expansion of fossil fuel extraction/production Support rapid acceleration/increased funding for active

transportation; include health/equity accounting in transportation planning

Strengthen building standards for climate resilience Urge public pension systems to divest from fossil fuels Mandate implementation of extreme heat guidance Regulate methane leakage in gas

extraction/production/transport Support green zones and just transition Create incentives for sustainable ag and peri-urban ag Make polluters pay e.g. carbon tax, nitrogen fertilizer tax Hold every agency and department accountable for CHE Be a leader. Talk to your constituents and colleagues

IPCC Key

Messages

40

Human influence on the climate system is clear

The more we disrupt our climate, the more we risk severe, pervasive and irreversible impacts

We have the means to limit climate change and build a more prosperous, sustainable future

IPCC AR 5 Synthesis Report 2014

Linda’s Key

Messages Climate change is affecting our

health and well-being now.

Climate change is a threat multiplier, exacerbating existing health challenges and health inequities

Low-income and communities of color suffer a “climate gap”

We can transform our systems to create healthy, equitable, sustainable communities
