Johannesburg Leads the Way: Mainstreaming Climate Action to Cut CO₂ Emissions

Johannesburg is taking bold steps to integrate climate action into all aspects of city life, aiming to reduce CO₂ emissions while fostering sustainable growth and resilience.

The Challenge

In 2014, a staggering 87% of South Africa’s energy was derived from fossil fuels. Rather than adopting a narrowly energy-focused, short-term approach to emissions reduction, Johannesburg has embraced a holistic strategy, embedding climate change mitigation across sectors of society. This comprehensive approach ensures that environmental responsibility becomes part of the city’s daily operations, planning, and long-term vision.

The Solution

Johannesburg laid the foundation for long-term sustainable growth in 2006 with its first comprehensive strategy for development. Building on this vision, the city introduced the Climate Change Strategic Framework (CCSF). The CCSF is designed to coordinate climate action across municipal departments while engaging communities, businesses, and citizens in collaborative efforts.

Key to this strategy is a bottom-up approach to measuring greenhouse gas emissions, which relies on contributions from both city departments and local stakeholders. Johannesburg is also leveraging the C40 CURB modeling tool, enabling planners to assess the energy and emissions impact of various low-carbon interventions and prioritize the most effective solutions. By uniting municipal bodies, private enterprises, and communities, the city aims to create a coordinated, city-wide push toward a greener, more resilient future.

Environmental and Economic Benefits

The CCSF will drive projects that significantly reduce CO₂ emissions while improving Johannesburg’s urban environment, from cleaner air to sustainable urban infrastructure. Economically, the city is already leveraging climate investments: in 2014, Johannesburg issued $143 million in green bonds to fund climate mitigation initiatives, feeding directly into its holistic strategy.

Through this integrated framework, Johannesburg is not only tackling climate change but also setting an example for cities worldwide, demonstrating that sustainable development and economic growth can go hand in hand.
