How scores work

DeepSeek scores 43 out of 100 — laggard. Little or no disclosure, fossil-backed capacity, or active disputes with regulators and communities. Confidence in this score is mostly estimates (C).

What helps

  • Efficiency · Full training run of 2.788M H800 GPU-hours disclosed in the technical report; MoE activates 37B parameters per token.

What hurts

  • Carbon · Training and first-party serving run on China's grid, with no renewable procurement disclosed.
  • Water · No water data of any kind.
  • Commitments · No climate or water commitments published.

What nobody knows

  • Per-prompt energy disclosed
  • Per-prompt water disclosed
  • Annual environmental report
  • Location-based Scope 2 reported
  • Data-center locations public
  • +3 more

DeepSeek-V3 was trained in 2.788 million H800 GPU-hours — about $5.6M at rental rates — and its mixture-of-experts design activates 37B of 671B parameters per token. SemiAnalysis puts the company's actual fleet at around 50,000 Hopper GPUs. The weights are open, so inference can be measured independently, but the company publishes no energy, water or emissions data and serves from the Chinese grid.

ecogpt.co estimate; no company figure.

How we got this number

DeepSeek-V3 is a 671B mixture-of-experts model that activates 37B parameters per token — about two thirds of a dense frontier model's work at Epoch's 0.3 Wh. Uncertainty roughly ±3×.

Water per promptWater evaporated cooling the servers for one request. Scope matters: on-site cooling only, or also the water used to generate the electricity (which adds ≈1.8 mL per Wh).

mL / typical prompt
≈ 0.40 500 mL bottles per 1,000 prompts
ecogpt.co estimateecogpt.co estimate. Our own estimate from published factors. The working is shown next to the number; treat it as an order of magnitude, not a measurement.DeepSeek (arXiv 2412.19437)Epoch AIKoomey Analytics

On-site cooling only, so comparable with Google and OpenAI's figures.

How we got this number

0.2 Wh per prompt × 1 L/kWh (estimated WUE for Chinese colocation sites). Counting the water evaporated to generate the electricity adds ≈0.36 mL.

Carbon per promptGreenhouse gas from one request on the grid where it actually runs. Below 0.1 g is clean. A kilometre in a petrol car is about 170 g.
0.116
gCO₂e / typical prompt

Location-based: what the grid actually emitted. Renewable certificates would bring the market-based figure near zero.

How we got this number

0.2 Wh × 580 gCO₂/kWh (Chinese grid, location-based).

Annual emissionsThe company's whole yearly footprint, in million tonnes of CO₂e. Clouds and device makers dwarf pure labs because they also count shops, logistics or products. Compare the trend, not the size.

ecogpt.co estimateecogpt.co estimate. Our own estimate from published factors. The working is shown next to the number; treat it as an order of magnitude, not a measurement.Tom's Hardware

Location-based estimate for the AI fleet only; not comparable with a full corporate inventory.

How we got this number

65 MW × 8,760 h × 80% utilisation × 580 gCO₂/kWh (Chinese grid). Compute only — nothing else the company does is counted.

Emissions trendDirection of travel against last year or the company's own baseline. Negative is good. Positive means the AI build-out is outrunning clean energy.

How we got this number

SemiAnalysis reports orders for 'many more' China-specific H20s on top of the ≈50,000 Hopper fleet; a 50% year-on-year increase in compute is the conservative reading.

How we got this number

No disclosure. Chinese colocation sites typically use evaporative cooling; 1.0 L/kWh is a mid-range assumption.

Clean electricityShare of electricity matched with renewable or carbon-free sources. Annual matching counts certificates bought anywhere; hourly matching on the same grid is far stricter.

How we got this number

China's grid generated about 35% of its electricity from non-fossil sources; DeepSeek discloses no renewable purchases.
