The CCP Campaign works with municipalities to (1) understand how local actions and practices contribute to the emissions that cause air pollution and global warming, (2) strengthen local capacity to develop plans and implement actions to cut local emissions, and (3) promote best practices that reduce energy use in buildings and transportation, promote renewable sources of energy, and improve waste management. Local governments sign commitments to join the campaign and undertake activities that reduce greenhouse gas emissions. They undertake capacity-building activities that look into local policies, plans, and programs.

Five Milestones are used to gauge the progress of the campaign participants.

Milestone 1: Emissions Inventory and Forecast
Milestone 2: Setting a Reduction or Avoidance Goal
Milestone 3: A Climate Action Plan
Milestone 4: Measures Implemented
Milestone 5: Monitoring and Verification

ICLEI also support cities to protect the climate through (1) Training and Technical Assistance, (2) Emissions quantification software tool (3) Commitment-Tracking, and (4) Information Exchange (i.e. newsletters, website, case studies, and peer exchange with international experts and network of local governments).

Local governments in Southeast Asia zero in on sectoral goals that strategically link global climate protection with access to basic services, local economic viability, and air quality management.
