Practical action

10 climate-action starting points

  1. Measure before setting targets. Understand the main sources of emissions or climate risk in your home, project or organization.
  2. Improve energy efficiency. Reduce avoidable energy use through efficient equipment, buildings and operating practices.
  3. Choose lower-emissions electricity where feasible. Consider renewable electricity, distributed solar or credible clean-energy options available in your context.
  4. Shift transport where practical. Walk, cycle, use public transport, share trips or choose efficient/electric vehicles where suitable.
  5. Reduce food waste. Plan purchases, store food well and use surplus before it becomes waste.
  1. Protect and restore ecosystems. Support protection of forests, wetlands and other ecosystems rather than relying only on planting new trees.
  2. Cut methane where possible. Address methane sources in waste, agriculture and fossil-fuel systems within your sphere of influence.
  3. Prepare for climate hazards. Use local risk information and strengthen heat, flood, drought, water and emergency plans.
  4. Use your organization's influence. Include climate considerations in procurement, facilities, travel, investment, communications and project design.
  5. Support informed collective action. Learn from credible evidence, participate in community processes and encourage effective policies and implementation.

Research hygiene

Before publishing a climate claim

  • Check the date and geographic scope of the source.
  • Read the original report rather than relying only on a headline or social post.
  • Distinguish observed measurements, model projections, scenarios and opinions.
  • Keep the source attached to the specific claim it supports.
  • Avoid presenting a single statistic without its definition, time period and uncertainty where relevant.
