What is RE100?

RE100 is a global, collaborative initiative led by The Climate Group in partnership with CDP, which brings together influential businesses committed to 100% renewable power and works to massively increase corporate demand for – and delivery of – renewable energy. Businesses account for around half of electricity used worldwide. Switching this demand to renewable energy will aid the transition to a net-zero emissions economy. Transitioning all businesses to 100% renewable electricity could save nearly 15% of carbon emissions worldwide.

Which sources of energy does RE100 consider 'renewable'?

RE100 considers the electricity generated from biomass (including biogas), geothermal, solar, water and wind as renewable energy sources.

What's the scope of RE100?

RE100’s scope is restricted to renewable electricity (RE) sourcing only. The purpose of the campaign is to accelerate a global transition to a renewable electricity system by building and enabling the corporate market for renewable energy, at scale. We therefore work only within recognized RE tracking systems, certificates, attributes and other contractual instruments (such as PPAs). Carbon credits, UN-REDD projects and carbon offsets or other greenhouse gas (GHG) attributes are not applicable to RE100, as these measure carbon across a wide variety of sources and sinks, rather than the production and use of renewable electricity. However, progressing towards a 100% renewable electricity commitment reduces a company’s carbon footprint and therefore the need to purchase GHG attributes.

What are the next steps once a company joins the RE100 campaign?

RE100 member companies must progress towards their 100% commitment in line with the Technical Criteria. They must report on this progress on an annual basis via the RE100 reporting spreadsheet or the CDP climate change questionnaire. If a company already reports to CDP, we encourage them to also complete the RE100 reporting spreadsheet, which provides more detailed information on their electricity consumption. Companies are also encouraged to take part in the campaign activities, to share knowledge with peers, inspire others to follow, and publicly advocate for the clean energy revolution.

By which date must a company reach 100% renewable electricity?

RE100 companies must select a target date for achieving 100% renewable electricity. The minimum requirements are:

• 100% by 2050, with interim steps of at least

• 30% by 2020

• 60% by 2030

• 90% by 2040

If a joining member company is already at 100% renewable electricity, they are invited to share the date they reached this achievement. In this case, and if the company has a year-on-year rolling target, its target year will be the reporting year.

The majority of joining companies select a target date in the range of 2020 – 2030. Based on the rate at which the global power system needs to be decarbonized to meet the ambitions in the Paris Agreement, no company should set a date later than 2050. A leadership standard would see companies setting a 100% renewable electricity target by 2030.


What data is requested by RE100 during the reporting process and why?

The RE100 campaign is designed for businesses to commit to 100% renewable electricity. This requires the transparent and accurate reporting of the organization’s electricity and renewable electricity consumption. RE100 also asks for other information such as the organization’s strategy towards renewable energy sourcing and types of renewable energy sourcing options and technology. The RE100 reporting process is managed by CDP through its flagship disclosure platform and allows RE100 to verify the data that companies are submitting against the RE100 Technical Criteria and further use the data for analysis during preparation of the annual RE100 progress report.

What is the difference between renewable electricity consumption and production targets? Which target does RE100 refer to?

RE100 companies are permitted to use renewable electricity consumption, production, or a combination of both to achieve their 100% target.

A renewable electricity consumption target is one in which the goal is to “consume” (use or source) a specified percentage or amount of renewable electricity by the set target year. Consumption targets are used by companies that primarily focus on consuming renewable electricity purchased from suppliers and may also, in part, be self-generated. Companies are considered to have met their RE100 goal when the renewable electricity they have purchased and self-generated matches the total amount of physical electricity used in that year.

A renewable electricity production target is one in which the goal is to “produce” (or generate) a specified percentage or amount of renewable electricity by the set target year. This choice of target is relevant for companies that invest in renewable generation projects and may produce renewable electricity in excess of what they consume. Companies are considered to have met their RE100 goal when the electricity produced by company-owned generation matches the total amount of physical electricity used in that year. To count the renewable electricity you produce towards your RE100 target, you must retire the renewable electricity attribute certificates, such as RECs, associated with the production equivalent to the amount claimed to avoid double-counting.

What is a renewable energy contractual instrument?

A renewable energy contractual instrument is a contract between two parties for the sale and purchase of energy, which is bundled with attributes about the energy generation, or unbundled attribute claims. Markets differ as to what contractual instruments are commonly available or used by companies to purchase energy or claim specific attributes about that energy, but they can include energy attribute certificates (RECs, GOs, etc.) and direct contracts such as Power Purchase Agreements (PPAs).

What is an Energy Attribute Certificate (EAC)?

An Energy Attribute Certificate (EAC) is a category of contractual instruments used in the energy sector to convey information about energy generation to other entities involved in the sale, distribution, consumption or regulation of electricity. 1 EAC = 1 MWh of renewable electricity. EACs are issued to renewable electricity generators operating within the same market boundary as the claimant. EACs exist in markets with reliable tracking systems to ensure that no double counting of the attributes takes place. Where certificates are purchased directly, and certification programs are not used or available, the exclusive claim of those attributes must otherwise be verified.

A bundled EAC means that it comes with the physical delivery of electricity (such as through a direct PPA), and unbundled means that it comes without the physical delivery of electricity. It is important to note that EAC’s are not offsets. They are contractual instruments that allow companies to accurately account for their renewable electricity purchases.

Which attribute tracking systems are currently accepted by RE100?

The following attribute tracking systems are currently accepted:

• RECS (US and Canada)

• GOs or REGO (Europe)

• T-REC (Taiwan)

• Green Power Certificate/J-Credit (renewables) (Japan)

• I-REC (International)

• TIGR (International)

• Other tracking systems that meet standards set out in Credible Claims.

What is the quality criteria for tracking instruments?

In order to make credible claims about the contractual allocation of attributes, the following criteria must be met:

• Credible generation data

• Attribute aggregation

• Exclusive ownership (no double counting) of attributes

• Exclusive claims (no double claiming) of attributes

• Geographic market limitations of claims; and

• Vintage limitations of claims

For further information on these criteria please refer to Making Credible Claims.

Can a company use carbon offsets or avoided emission statements in RE100 reporting (or for making renewable energy consumption claims)?

No. While RE100 is aligned with the Greenhouse Gas Protocol’s method for greenhouse gas accounting, RE100 focuses on electricity use, not carbon emissions. As a result, carbon offset programs and avoided emission statements are not applicable tools to achieve the 100% target and should not be used in RE100 reporting.

What constitutes a market?

Please refer to our note on Market Boundary Criteria.


What should a company do when renewable electricity sourcing options are not available in a region of operation?

Procuring renewable electricity in some countries/markets is challenging. If a country does not have its own energy attribute tracking system, RE100 recommends international certificate systems such as I-RECs or TIGRs, which are intended for regions without an existing or reliable attribute tracking system. Companies can also explore direct procurement contracts such as a PPA with a supplier, and secure renewable energy attributes contractually. If these options are not available, RE100 recommends that companies either investigate onsite (or near-site) renewable options, which is a popular option in China, or that the company tries to aggregate demand with other companies in the same region to develop a solution. RE100 is happy to discuss opportunities to connect members in regions where sourcing renewable electricity is particularly challenging.

What should a company do when it has a very small electricity consumption in a few regions where renewable electricity sourcing options are limited or not available?

Renewable energy is a fast-evolving sector and we expect that those regions will have renewable energy sourcing options available in near future. RE100 recommends that companies should investigate whether onsite renewable electricity for those locations is possible. A 1% materiality threshold applies to country level consumption that we request companies to report on. This means that we do not require companies to report on countries that represent less than 1% of their total electricity consumption in each given reporting year (although RE100 still encourages this to be done). However, the 100% commitment still covers those geographies.

Can a company count the renewable energy on the grid towards its target through the utility mix figure where an attribute system does not exist?

Companies can only claim utility/grid mix renewables when these are accompanied by equivalent attribute certificates (REC,GO,I-REC), or statements within the legal/contractual document from the supplier/utility stating the % RE (in terms of energy e.g. MWh and not the capacity e.g. MW). Any company wishing to report grid renewables that are not verified in compliance with the above, must clearly separate this figure out from their Purchased RE figure in their reporting to RE100. Companies can do so by selecting the ‘Other’ option in the total RE procured by country section of the RE100 reporting spreadsheet (please add additional information in the comment box). However, this consumption will not be used for making renewable electricity claims towards your RE100 target.
