Take the Jump
- The City of Melbourne is part of a grouping of 100 cities from around the world (C40 Cities Climate Leadership Group) which have committed to reducing GHG emissions consistent with a 1.5degC World (67% confidence) [1].
- Emission targets have been informed by a report titled The Future of Urban Consumption in a 1.5°C World [2]
- The report models the effects of several interventions to reduce GHG emissions:
- Reducing the number of new clothing items bought each year
- A shift to a plant based diet
- Keep electrical products for 7 years
- No personal cars for travel
- Holiday local or travel short haul once every 3 years
- Advocate for systemic change
C40 Cities and Climate Change Pledges
- C40 Cities have set the following targets
- 50% reduction in emissions by 2030
- net zero emissions by 2050
Climate math: What a 1.5-degree pathway would take
- These targets are based on good science.
- A 50-55% reduction on CO2 emissions by 2030 based on 2010 levels
- Staying within a 570 GtCO2 cumulative carbon budget. Budget of 570 GtCO2 emissions from 2018 onward offers a 66% chance of limiting global warming to 1.5°C, when assessing historical temperature increases from a blend of air and sea-surface temperatures.
Limitations
- Climate math publication [[3]]
