hard questions, with answer notes
01Summary
Plan an 8–12 minute talk inside a 60–90 minute China Pavilion session. Lead with one verified emission-reduction number, show measured results for any ecological measures, and bring something to release.
The slot is short. COP28 China Pavilion sessions ran 75 minutes with several speeches, 2–3 keynotes and a roundtable. Plan 8–10 slides for 10 minutes.
Some topics are still new on that stage. From COP26 to COP30 no China Pavilion session focused on integrated hydro-wind-solar bases or on fish and river protection.
Coverage follows a deliverable and a foreign voice. Every well-covered energy-company session released a report, initiative or MoU, and had an IRENA, IEA, WBCSD or host-country speaker.
One claim per slide. Sentence headlines, one chart or 1–2 photos, body text 24 pt or larger, English-first, every chart label translated.
Pass the credibility test. Give each number its method, baseline and verifier; label avoided emissions as such; add one line on what you are still improving.
Rehearse the hard questions: reservoir methane, fishway results, verification, coal in the group's portfolio, cumulative river impacts, local communities.
Language: speak English only if fluent; otherwise Chinese with interpretation, and send interpreters the slides, script and glossary 3–5 days ahead.
Tech: 16:9, 1920 × 1080 PPTX, Microsoft fonts, video also as a separate MP4, two USB sticks; expect about 15 minutes to set up.
Most reach happens after the room. Pavilion replays often get only hundreds of views. Bring your own camera; publish a 2–3 minute English recap and the deck PDF within 48 hours.
Ask the organiser early for the slot date and length, language and interpretation, AV kit and livestream platform. As of 16 Oct 2026 the COP31 China Pavilion schedule is not public; at COP28 it came out one day before opening.
02How presenting at COP works
A China Pavilion session is a pavilion event, not an official UN side event. The Chinese organiser sets the format, and UN webcasting and room rules do not apply. Expect a 60–90 minute session shared by many speakers, which leaves a company speaker roughly 8–12 minutes.

Session length
Recording
Official UN side event (Blue Zone)
UN secretariat; admitted observers and Parties apply through SEORS
Fixed 90 min (75 at COP26); head table of 6–8
Shrinking: YouTube live at COP26–28, recordings only at COP29, none at COP30
Country or organisation pavilion (Blue Zone)
Each pavilion owner; the host leases the space commercially
Owner's choice: 75 min at the China Pavilion (COP28), 45 min at the Canada Pavilion (COP31), 50 min at the Pacific pavilion (COP29)
The Ministry of Ecology and Environment runs it, and the National Center for Climate Change Strategy and International Cooperation (NCSC) issues the schedule. The COP28 schedule came out on 29 Nov 2023, one day before the conference opened (Shanghai MEE repost of the NCSC notice). Slots have become fewer and more curated:
COP
China Pavilion programme
COP30 Belém, 2025
19 thematic side events, 14 special events, 4 exhibitions (MEE)
100+ side events over 9 themed days in 2 parallel rooms, incl. a Renewable Energy Day and an Enterprise Day
The COP28 grid ran 75-minute sessions starting 09:00, 10:45, 13:00, 14:45 and 16:30, with 30-minute changeovers (Sina COP28 schedule). A typical session opens with several short official remarks, then 2–3 keynote or case presentations, then a roundtable of 4–7 people, often with a report launch. One COP28 session fitted 3 keynotes and 7 discussants into 75 minutes (China News Service).
The closest precedent for an integrated hydro-solar base is SPIC Huanghe Hydropower's session "Clean Energy Promotes Green Transition" on 9 Dec 2023. Seven guests gave remarks, six organisations joined a moderated exchange, and about 29,000 people watched the global livestream (China Daily). At COP30 the energy session put IRENA's director-general and Denmark's climate ambassador beside China's envoy and launched four reports (Xinhua).
No published source gives the China Pavilion's working language, interpretation, AV kit or livestream platform. Confirm all four with the organiser.

No testing until 15 minutes before the slot.
03How past presenters built their decks
Chinese energy companies at the China Pavilion lead with portfolio scale, then a flagship case, then a cooperation offer. The sessions that got coverage all had a deliverable and an international co-speaker.

What the talk or stage did
COP30, 18 Nov 2025
Carbon neutrality and smart energy; Tsinghua with Huaneng, its first
Report release; Huaneng's floating PV platform was the only Chinese case picked for an international case collection
COP30, 13 Nov 2025
Building a New Power System; State Grid, its first
IRENA keynote, Brazil's power regulator on stage, a WBCSD-moderated roundtable; an initiative with 51 co-signers; pipa and tea-art before the start
Scale first (over 240 GW, over 70% clean, 47 countries), then Saudi PV cases, then a cooperation offer. A CEC white paper launch. About 80 in the room, about 30,000 online

What these sessions show:
A fixed template. Official remarks, then the company leader, then international keynotes, then a roundtable, then a release (report, initiative or MoU), then a group photo. A company speaker speaks inside that frame; it does not open the session.
Coverage follows deliverables and foreign voices. Every well-covered case had a release and a speaker from IRENA, IEA, WBCSD or the host country. In Antalya the equivalent is a Turkish utility or regulator, or IHA or IRENA on hydropower.
Rooms are small; the stream is large. One COP28 pavilion room held about 40 seats (S1). SPIC had about 80 people in the room and about 30,000 online.
Interpretation existed at COP28. The China Pavilion used iFlytek simultaneous interpretation with live bilingual transcripts (People's Daily).
Recurring weak spots: chart labels left in Chinese under English titles, non-native English on screen, and messages stated as priorities rather than data.
The one public China Pavilion deck: ERI at COP27
The Energy Research Institute's 27-slide English deck is the only complete China Pavilion deck found online (original PDF). It runs: title, institute introduction, a quotation, outline, global challenges, China's progress in charts, regional cases, 2060 scenarios, wrap-up. The structure is clean and the outline uses a strong project photo. But the charts keep Chinese labels, units and legends under English titles (p10, p24).

A template worth borrowing: the international case one-pager
Huaneng's "Yellow Sea No.1" was the only Chinese case in the Sustainable Business COP30 energy-transition selection (The Paper). Its one-pager uses a fixed international template: objectives, partners, case stage, risk, scalability, innovation, economic impact and CO2 impact. It states the risk openly, which Chinese stage decks usually leave out. The same structure fits a hydro-wind-solar and ecology case, and can double as the handout.

International decks: what the strong ones share
No hydropower deck from any COP is publicly downloadable: IHA and Itaipu publish only concept notes, agendas and recordings. The decks below are the closest real examples: science briefings on energy and rivers, one best-in-class data deck, and organisation and company decks. Links go to the original publishers.
Strong slides to copy (G1–G9). Sources: Global Carbon Project, IPCC, IHRB, Eight-Japan Engineering Consultants. Tap to enlarge.
The weak decks fail in predictable ways. ADB's slide 3 carries about 410 words; the RITE/IIASA deck has a median of 132 words per slide; UNESCO's slide 13 overlaps boxes and clips text; an IPCC flowchart cannot be read from the room. None of the four ends with an ask.
What separates strong from weak, in five rules:
One message per slide, stated as a sentence or a hard number.
One chart or one or two photos per slide, labelled directly, with a source line.
About 40 words of body text or fewer.
The logo once in the master, not a stack on every slide.
A measured outcome on every project card, and an offer or next step at the end.
Decks that are not posted after the event effectively disappear. The IPCC keeps every speaker's deck and recording on its outreach portal, and the UN asks side-event organisers to upload slides to SEORS (COP28 handbook). Post the final PDF on your English website as well.
04Recordings and key frames
There are full public replays of some China Pavilion sessions, but none was found for an energy company's session. The closest peer is CNPC's 2.5-minute English recap of its COP30 central-SOE session (A5). All links were opened and checked on 16 Oct 2026.
Watching from China: Bilibili copies
Six of the 25 recordings have a Bilibili copy, and Kofe's speech has one as news excerpts. The other 18 have no Bilibili copy; the key frames at the end of this section cover them.
The only hydropower-specific recording found. Ministers, utility CEOs and IUCN share one panel. Its title card reads: "Water, wind and sun together will power the sustainable growth of the future."
Not the IUCN opening, as labelled: a session on bird protection on power lines. Right topic, weak delivery: a slide shown in a browser window, Chinese-only screens, about 8–10 people
Slides rarely reach the replay. China Pavilion streams use one fixed camera on the lectern, so side-screen slides are not seen online. Say every key number aloud.
Online reach is small. China Pavilion replays have 85–600 views, against 684,186 for Mottley and over one million for a Guardian clip of Kofe. The room, state-media packages and the company's own short recap reach more people.
Language is shifting to English. The COP27–28 China News Service replays are in Chinese; the COP29 forum and the COP30 CNPC recap are in English.
The famous talks are 4–9 minutes, use no slides and hang on one anchor: a number, a place or a single image.
COP31 sessions will likely appear on the presidency's "COP31 Türkiye" YouTube channel, which already streamed an IEA energy-transition dialogue in April 2026.
Key frames
These 67 frames capture the moments worth studying, so you can learn from them without opening YouTube. Each timestamp links straight to that moment. Frames were captured from the streams on 16 Oct 2026.
State Grid's English exhibit boards feature a host-country project. A bilingual session card names the session in every wide shot. The audience uses headsets
Put date, time and venue on the title card. The screen showed the wrong speakers: assign one operator. A hydropower country lands its point with one number
A 10-item text slide stays unreadable on camera for an hour
05Best practices and lessons
The decks that work at COP make one claim per slide, back it with checkable data, and tie it to global goals rather than domestic slogans.
Slide design for a pavilion room
One claim per slide. Write each headline as a full sentence that states the point, e.g. "The base avoids X million tonnes of CO2 a year." Back it with one chart or one photo. In Penn State studies, audiences shown these "assertion-evidence" slides understood and remembered more (Penn State research).
Big type, little text. Body text 24–28 pt or larger, headlines 36–40 pt, about 30 words of running text per slide. Use dark text on a light background in brightly lit pavilions (W3C accessible presentations).
Expect a small, noisy room. The Canada Pavilion at COP31 seats about 25, runs 45-minute events with 4–5 speakers, and shows two screens in two languages (Canada Pavilion FAQ).
Photos: 1–2 per slide, real and sharp (at least 1920 px wide for a full-bleed image). Show the work itself: a fishway, a revegetated slope with before/after, a technician at work. Never alter what a photo documents, and label renderings "illustrative".
Charts: one message each. Label lines directly, spell out units (t CO2/yr, GW, TWh; no 万/亿), highlight the one series that matters, and skip 3D, dual axes and many-slice pies.
Maps: one simple locator map on the official standard base map. Describe the site functionally, e.g. "a high-mountain river basin in western China".
Logos on the title and closing slides only. A logo wall on every slide reads as promotional.
English-first slides. With one screen, add at most a small Chinese line under the headline. Never set two full languages side by side. Give interpreters both versions.
Story and framing
At COP30 the best-attended China Pavilion events were on south–south cooperation; visitors came to learn how a developing country runs its energy transition (Carbon Brief, 13 Nov 2025). At a COP28 China Pavilion session, Chinese communicators themselves said their stories are too technology-only, should explain why, and should not tell others what to do (The Paper, 8 Dec 2023).
A 10-minute arc that follows this advice:
0–1 min — The answer. What the base delivers for the climate, in one sentence and one number.
1–3 min — Why this design. Why hydro, wind and solar together: hydropower balances variable wind and solar.
3–5 min — Results. Generation, avoided CO2 with its method, construction-phase savings, one relatable equivalent.
5–8 min — Protecting the river and the land. Two or three measures, each with monitoring data on outcomes.
8–9 min — What others can reuse. The transferable model, including one thing you would do differently.
9–10 min — The invitation. Data sharing, partnerships, a site visit, the QR code.
Replace domestic terms with plain international English:
Chinese term
Say instead
双碳
China's goals to peak CO2 before 2030 and reach carbon neutrality before 2060
水风光一体化 / 多能互补
Integrated hydro-wind-solar base; hydropower balances variable wind and solar
增殖放流
Releasing hatchery-reared native fish (stocking)
鱼道 / 过鱼设施
Fishway / fish pass
生态流量
Environmental flows
植被恢复
Revegetation / habitat restoration
标准煤
Convert to tonnes of CO2
万 / 亿
Thousands, millions, billions; or TWh
生态文明, 绿水青山…, 高质量发展
Drop, or explain the idea in one plain sentence
For relatable equivalents, US EPA factors are a common reference: 4.29 t CO2e per passenger car per year, 7.45 t per US home's energy use per year (EPA calculator). Use one equivalent, not a stack, and label it approximate.
Credibility: what observers check
NGOs and journalists judge corporate claims against the UN expert group report Integrity Matters (2022): actions not announcements, absolute numbers not only intensity, published data, and independent third-party verification (UN HLEG report). Build the deck to pass that test:
Footnote every headline number with method, baseline, year and verifier.
Call avoided emissions "avoided emissions". Never net them against your own footprint or call the base "zero-carbon".
Show outcome data for each ecological measure, e.g. fish species and counts passing per year, vegetation cover before and after.
Add one line on what you are still improving. It earns more trust than an all-positive deck.
Offer the full monitoring or ESG report via a QR code.
Avoid "zero emissions", "no ecological impact", "fully restored", "perfect harmony" and unverified "world-first / world-leading".
Hydropower draws specific scrutiny. The IPCC median life-cycle intensity is 24 g CO2e/kWh, but reservoir emissions are highest in the first 10–20 years after filling (IHA factsheet). A review of fishway studies found mean passage efficiency of about 40–70% depending on type (Bunt et al. 2012). So observers want monitoring numbers, not the existence of a fishway.
Hard questions to rehearse
Answer pattern: acknowledge the concern, give the number and method, name the verifier or report, offer a follow-up. Keep each answer to 30–60 seconds and never debate national policy.
Swipe the table sideways →
Likely question
Answer with
Reservoirs emit methane. Is your hydropower really low-carbon?
The project's measured or modelled g CO2e/kWh against the IPCC median of 24; your monitoring plan
Fishways often fail. How many fish actually pass?
Species, counts and years from monitoring; the method and partner; stocking as a complement to habitat, not a substitute
Who verified your emission reductions, against what baseline?
The methodology, grid emission factor and verifier; avoided emissions reported apart from your footprint
Your group still runs coal plants. Isn't this greenwashing?
The group's transition facts, prepared in advance, stated briefly without deflecting
What about cumulative impacts on the river?
Basin-level planning, environmental flows, connectivity measures, monitoring; acknowledge the trade-off
Were local communities consulted, and are they better off?
The consultation process, benefit-sharing figures, grievance mechanism; offer to connect if outside your remit
Is the project certified to an international standard?
The standards that apply; whether you are open to independent assessment; no overclaiming
Wind and solar curtailment is high. Does integration work?
Utilisation and curtailment rates, and how hydro balancing changed them
Delivery and interpretation
Slides to time: 8–10 content slides for 10 minutes, 12–14 for 15 minutes.
Script length: about 1,000–1,200 words for 10 minutes when interpreted, roughly 110–130 words a minute. This rate is an estimate from interpreters' guidance (AIIC speaker guidelines).
Language: speak English only if fluent; otherwise speak Chinese with interpretation and open and close with two rehearsed English sentences. Announce any language switch (EC interpretation service tips).
Interpreters: send slides, script, a 20–40 term glossary and name pronunciations 3–5 days ahead. Booths are often far from the screen (AIIC).
Sentences: short, one number per sentence, numbers said clearly. Speak rather than read; reading speeds you up (AIIC).
Rehearse three times, once in front of a non-Chinese listener to catch jargon. Cut whatever overruns; the moderator will cut you anyway.
06COP31 checklist
COP31 runs 9–20 Nov 2026 at the Antalya Expo Center, about three and a half weeks away. The priorities now are to confirm the session format with the organiser, lock the numbers and their methods, and get the English professionally reviewed.

Energy and Transport day
The natural hook for a clean-energy story. At COP30 the UN put topic side events on the days before and after its thematic day
Türkiye is on UTC+3, five hours behind Beijing, so a 10:00 session in Antalya is 15:00 for a livestream audience in China. The free COP31 e-Visa is multiple-entry, valid 1–30 Nov, and takes up to 7 working days. Passports need 90 days' validity after arrival, and travel insurance is mandatory (cop31.tr visa and entry).
