Climate change presents the single biggest threat to human development, and its widespread impacts disproportionately burden the poorest and most vulnerable households in fragile and rural developing contexts – particularly women and children. According to the Intergovernmental Panel on Climate Change’s (IPCC) latest report, ‘between 2010 and 2020, droughts, floods and storms killed 15 times as many people in highly vulnerable countries, particularly in Africa — which is responsible for less than 3 percent of global emissions – than in the wealthiest countries’. Recognising environmental degradation and climate change are key accelerators of extreme child vulnerability, World Vision (WV) approved the Environmental Stewardship Management Policy (‘the Policy’) and Guidelines (‘the Guidelines’) in 2021. To support the implementation of the Policy and Guidelines, WV has developed this Environmental Stewardship and Climate Action Handbook (‘the Handbook’) to help offices across the WV Partnership implement best practice environmental management strategies both in the field and in our operations and facilities. Integrating environmental stewardship and climate action into all our work – whether that be in our Area Programmes, grant projects, responses to disasters or advocacy – is critical to achieving WV’s strategy. As a Christian organisation we are compelled to follow the ways of Jesus Christ, calling us to care for the ‘least of these’ (Matthew 25:40) – the vulnerable children who are disproportionately impacted by climate change. Our response to the degradation of the environment is not motivated by political expediency or funding – but because we are called to steward God’s creation (Genesis 1:28).
