- Going concern
- Affirmed
“The charitable company has cash resources to meet its day to day working capital requirements. Current forecasts indicate that the charitable company expects to be able to operate within these facilities for the foreseeable future. The trustees continue to believe the going concern basis of accounting is appropriate in preparing the annual financial statements.”
Significant events
- “TransitionZero hired a total of 15 new team members and continues to hire at a steady rate; it is projected that by the end of the first quarter of Financial Year 2026/2027 the team will have remained consistent at around 45 headcount (due to some attrition).”
- “Scenario Builder launch and impact. Our beta launch involved a launch at the Blue Planet Alliance event in Hawaii, a bootcamp for Indonesian planning and energy ministries, and a webinar to launch TZ-SB to our network.”
- “Modelling development. We published a series of five country-level modelling studies on 24/7 Carbon Free Electricity (CFE), made possible through the support of Google.org.”
- “Progress made on fundraising. We established relationships with Breakthrough Energy and the Global Grid Catalyst fund, and received funding from both during the course of the financial year.”
