Mission and programs · 2024

Mission

TO RAISE AWARENESS ABOUT THE POTENTIAL TO REDUCE ENVIRONMENTAL HARM BY SHIFTING ELECTRICITY USE TO PARTICULAR TIMES; TO ENCOURAGE THE DEVELOPMENT AND SPREAD OF COMMON PROTOCOLS FOR THIS PRACTICE.

Activities or mission (Part I)

TO RAISE AWARENESS ABOUT THE POTENTIAL TO REDUCE ENVIRONMENTAL HARM BY SHIFTING ELECTRICITY USE TO PARTICULAR TIMES; AND TO ENCOURAGE THE DEVELOPMENT AND SPREAD OF COMMON PROTOCOLS FOR THIS PRACTICE.

  • BELOW ARE SOME KEY HIGHLIGHTS OF WATTTIMES PROGRESS ON SEVERAL FRONTS IN FY25. 1. AER ASSISTANCE: WATTTIME CONTINUED TO GROW THE NUMBER OF PEOPLE WE WERE ABLE TO HELP AUTOMATE THEIR DEVICES TO SHIFT ELECTRICITY TO TIMES THAT REDUCE ENVIRONMENTAL HARM (WHICH WE CALL AUTOMATED EMISSIONS REDUCTION OR AER). IN FY25 WE SUPPORTED OVER 1 BILLION DEVICES TO USE AER. 2. AER EDUCATION: WE ALSO CONTINUED TO RAISE AWARENESS OF AER THROUGH GIVING TALKS, NEWS PUBLICATION, AND BY PUBLISHING FREE DATA TO ENABLE AER FREE ON SEVERAL SITES, SUCH AS CARBONTREASUREMAP.ORG, AND GRIDEMISSIONSDATA.IO. 3. RESEARCH TO MAKE AER MORE EFFECTIVE: IN FY25 WE DEVELOPED A NOVEL TECHNIQUE TO MAKE AER EVEN MORE EFFECTIVE AT REDUCING ENVIRONMENTAL HARM, BY ADDING IN BUILD MARGINAL EMISSIONS DATA. MORE INFORMATION AT GEM.WIKI/MBERS. 4. SUPPORTING HARMONIZATION OF METHODS. IN FY25, WATTTIME CONTINUED TO SUPPORT THE DEVELOPMENT AND SPREAD OF COMMON PROTOCOLS TO SHIFT ELECTRICITY USE TO CLEANER TIME, MOST NOTABLY BY SUPPORTING THE TECHNICAL WORKING GROUP FOR THE WIDELY USED GREENHOUSE GAS PROTOCOL. 5. CLIMATE TRACE EMISSIONS DATA RESEARCH: WATTTIME SERVES AS BOTH THE ELECTRICITY SECTOR LEAD, AND THE OVERALL COORDINATING SECRETARIAT, OF THE CLIMATE TRACE RESEARCH COALITION. CLIMATE TRACE COMBINES DATA FROM NUMEROUS DIFFERENT NONPROFITS, UNIVERSITIES, AND TECH COMPANIES IN ONE FREE SITE. IN FY25, THE PROJECT ESTIMATED EMISSIONS OF NUMEROUS POLLUTANTS, FROM METHANE TO SULFUR DIOXIDE, AT OVER 700 MILLION LOCATIONS WORLDWIDE. 6. EXPLORING NOVEL APPLICATIONS OF EMISSIONS DATA: IN FY25, WATTTIME ALSO SUPPORTED OTHER CLIMATE TRACE COALITION MEMBERS IN RESEARCHING WAYS TO EXTEND THE AER CONCEPT TO DEVELOP SIMILAR LOW-COST, DATA-DRIVEN WAYS TO REDUCE ENVIRONMENTAL HARM IN OTHER SECTORS OUTSIDE OF ELECTRICITY. THE COALITION PREPARED TO RELEASE SUCH TECHNIQUES IN NOVEMBER 2025.

Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 13 October 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
