Speaker Background and Context

• Author of 2018 IPCC report on 1.5°C warming
• Spoke to young engineers at major oil/gas company
• Young engineers confidently stated they could decarbonize fossil fuels by 2050 if rules applied equally to all competitors
• Management avoided answering the question

Climate Change Solution Framework

• Global warming requires stopping net CO2 emissions
• 85% of current CO2 emissions come from fossil fuels and industry
• Only two options to stop fossil fuels causing warming:
  • Ban fossil fuels globally (impractical and ethically questionable)
  • Decarbonize fossil fuels themselves

Problems with Alternative Approaches

• Global fossil fuel ban unlikely and unfair to developing countries in 2060s
• Renewable energy cost reduction alone insufficient:
  • Nuclear was promised "too cheap to meter" in 1970s but didn't materialize
  • Fossil fuel prices could fall in response to competition
  • Carbon-free alternatives must outcompete ALL fossil fuel uses (aviation, cement, etc.)

Decarbonizing Fossil Fuels Technical Solution

• Definition: 1 ton CO2 safely/permanently disposed for every ton generated
• Responsibility lies with fossil fuel companies, not consumers
• Engineers have known how for decades
• Primary method: Carbon capture and storage (CCS)
  • Capture CO2 from chimneys, power stations, blast furnaces, refineries
  • Purify, compress, re-inject underground
  • Deep injection into right rock formations = permanent storage (like original hydrocarbons)
• Alternative: Direct air capture for applications like aviation fuel (more expensive)
• Storage must last tens of thousands of years minimum

Implementation Timeline and Costs

• Cost-effective pathway to 100% carbon capture by 2050:
  • 10% capture by 2030
  • 50% capture by 2040
  • 100% capture by 2050
• Current capture rate: <0.1%
• 10% storage requirement by 2030 = few pence added per liter of petrol
• Unlike taxes, money directly spent on solving problem

Industry Scale and Capability

• Requires building CO2 disposal industry comparable to current oil/gas industry size
• Only fossil fuel companies have necessary:
  • Engineering capability
  • Financial resources ("deep pockets")
• Consumers can help by slowing fossil fuel use to buy time

Policy and Investment Implications

• Developing countries can use progressively decarbonized fossil fuels without absolute consumption limits
• Avoids constraining economic growth in emerging economies
• Current discussions focus on philanthropy/tax breaks for CO2 disposal
• Speaker argues profitable industry should pay for own cleanup

Call to Action by Audience Type

• Fossil fuel workers/investors:
  • Don't divest/sell assets to less caring parties
  • "You own this problem. You need to fix it."
  • Decarbonize products, not just portfolios
• Politicians/civil servants:
  • Evaluate climate policies: "How is it helping to decarbonize fossil fuels?"
  • Focus on increasing fraction of CO2 safely disposed
• Environmentalists:
  • Accept fossil fuel industry's central role despite discomfort
  • Leaks and cheating will occur but make decarbonization harder, not optional
  • Calling for industry death lets them "off the hook"

Final Message

• Global warming won't wait for fossil fuel industry to die
• Need help from unexpected places in divided times
• Engineers know how to solve it
• Management needs to "look up from their shoes"
