Science-Based TargetsParticipant companies set science-based targets to reduce greenhouse gas (GHG) emissions are considered “science-based” if they are in line with the level of decarbonization required to keep global temperature increase below 2 degrees Celsius compared to pre- industrial temperatures, as described in the Fifth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR5).
Example targets:
- Adobe Systems Inc. US. committed to a 25% reduction in absolute scope 1 and 2 emissions from 2015 levels by 2025, and reducing scope 3 fueld and energy related emissions per square foot by 15% in its owned and managed facilities
- French real estate investment trust, Gecina committed a 48% reduction in GHG emissions per square meter by 2030, from a 2014 base-year.
492 companies taking science-based climate action, and 141 companies with approved science-based targets.

*Over 130 companies are new members since January 2018.
Hill, J. (18 September 2018). More Than 130 Companies Have Made Science-Based Targets This Year Alone. CleanTechnica. Retreived from: https://cleantechnica.com/2018/09/18/more-than-130-companies-have-made-science-based-targets-this-year-alone/The new 130 companies could, if they have approved targets, reduce emissions by an order of magnitude of 135 Mt relative to current national policies by 2030. Our recent report (Global climate action of cities, regions and companies) assumes membership will grow to 2000 companies by 2030, and so already accounts for this impact.

C40 Advancing Towards Zero Waste DeclarationAll participant cities pledged to cut the amount of waste generated by each citizen 15% by 2030, reduce the amount of waste sent to landfills and incineration by 50% and increase the diversion rate to 70% by 2030.
Sample of participants:
- Johannesburg, South Africa
- London, United Kingdom
- New York City, United States
25 cities

C40 Cities Climate Leadership Network. Scores of Cities Commit to Bold Climate Action to Deliver on the Hightest Ambition of Paris Agreement. Retrieved from: https://www.c40.org/press_releases/scores-of-cities-commit-to-bold-climate-action-to-deliver-on-the-highest-ambition-of-paris-agreement. The largest reductions from this initiative will come from the reduced production of foods and materials. We estimate the direct emissions reductions from reduced greenhouse gas emissions from landfills to be around 0.5 MtCO2e; this number is small, as these cities represent 2% of the global population. If all countries were to adopt this target, it would results in a projected 20 MtCO2e of emissions reductions.
5
Net Zero Carbon Buildings CommitmentAll participant cities pledged to enact regulations and/or planning policies to ensure new buildings operate at net zero carbon by 2030 and all buildings by 2050.
Sample of participants:
- London, United Kingdom (city)
- Frasers Property, Australia (company)
- Yucatan, Mexico (region)
22 cities, 5 regions, and 15 companies


*Declaration launched at the Global Climate Action Summit.
World Green Buildings Council. (13 September 2018). Leaders Commit to Save 209 Million Tonnes of Carbon Emissions Equivalent (Co2e) by 2050 at Launch of World Green Building Council’s Net Zero Carbon Buildings Commitment. Retrieved from: http://www.worldgbc.org/news-media/WorldGBC-Launches-Net-Zero-Carbon-Buildings-CommitmentThis initiative could reduce between 1.9 and 2.2 GtCO2e, compared to the emissions reductions expected from current national policies. Our recent report (Global climate action of cities, regions and companies) already accounts for this initiative's 2030 target -- for all new buildings to be net zero -- through the Architecure 2030 initiative, and so likely accounts for this impact.
6
Green & Healthy Streets DeclarationParticipant cities pledged to transition to fossil-fuel-free streets by procuring only zero-emission buses from 2025, and ensuring a major area of the city has zero emissions by 2030.
Sample of participants:
- Milan, Italy
- Seoul, Korea
- Greater Manchester, United Kingdom

EP100The Climate Group’s global EP100 initiative in partnership with the Alliance to Save Energy brings together a growing group of energy-smart companies committed to using energy more productively, to lower greenhouse gas emissions and accelerate a clean economy. By setting ambitious targets and integrating energy efficiency into business strategy, leading companies are driving clean tech innovation while delivering on emissions reduction goals – inspiring others to follow their lead. The Climate Group estimates that if 100 companies double their energy productivity by 2030 – generating twice as much economic output for every unit of energy consumed – over 170 million metric tons of emissions could be avoided cumulatively, equivalent to taking 37 million cars off the road for a year.
Example targets:
- Woolworths Holdings South Africa pledged to double their energy productivity by 2020 compared to a 2005 baseline year.
- H&M pledged to achieve a climate positive value chain by 2040, double its energy productivity by 2030 and have 100% of its supplier partners enrolled in an energy efficiency program by 2025.
33 companies

*16 companies are new members as of the Global Climate Action Summit.
The Climate Group. EP100. Retrieved from: https://www.theclimategroup.org/project/ep100Based on the EP100's own calclations, its members could reduce emissions by a total of 170 MtCO2e, or by 20 MtCO2e/year by 2030. As companies can choose their own energy productivity metric (e.g. revenue/GJ of energy), it is not possible to review these results.

#ZEVchallengeThe Climate Group's #ZEVchallenge brings together leading initiatives for states (Under2 Coalition ZEV commitment), cities (C40 Cities - Green & Healthy Streets) and businesses (EV100) to commit to 100% zero emission vehicle targets by 2030.
Sample of participants:
- Clif Bar, United States (company)
- Medellin, Colombia (city)
- Quebec, Canada (region)
24 companies, 12 cities, and 24 regions

*2 companies, 12 regions and 12 cities are new members as of the Global Climate Action Summit.

Those currently planned would commit 150 MtCO2e, of which 50 MtCO2e is for those already being constructed (ibid). The coal-fired power plants that will be build in the future, but which are not planned, are not included in these numbers.
