Climate change is seldom discussed in mainstream social work. Its first presentations on the world stage occurred in Copenhagen during the Conference of the Parties (COP15). This article argues that the profession has an important role to play in: helping people understand the issues; promoting sustainable energy production and consumption; mobilising people to protect their futures through community social work; and proposing solutions to greenhouse gas emissions as indicated in two case studies, one based on a community initiative in the Global South, and the other in the Global North. The article also demonstrates that social workers can foster climate change endeavours that are equitable for all, for example the Equitable Carbon Sharing Scheme.
