Thesis

Climate solutions must be economically viable businesses. Fund technologies that profitably slash CO2 emissions, remove carbon from the atmosphere, and build climate resilience. Back technical founders solving "crazy scale" problems with 5-10+ year horizons.

Likely not a fit for

Vaporware, unproven technology without clear scale path, ventures without strong technical teams, fashion/consumer goods without genuine climate impact

Research briefRead more
Lowercarbon Capital Research Document Investment Thesis Lowercarbon Capital backs "kickass companies" that make real money slashing CO₂ emissions, sucking carbon out of the sky, and buying humanity time to decarbonize the planet. Founded in 2018 by Chris Sacca and Crystal Sacca, the firm believes climate solutions must be economically viable businesses, not just feel-good projects. Their approach is pragmatic: fund technologies that are genuinely profitable while addressing the existential climate crisis. The firm organizes its investment thesis into three core pillars: 1. Slashing New CO₂ Emissions - Until new emissions hit zero, temperatures will keep rising. The firm funds technologies that reduce sources of carbon dioxide, methane, and other greenhouse gases across energy and transportation, industrial materials, and agriculture. 2. Sucking Up Carbon - Recognizing we cannot zero out historical emissions overnight, Lowercarbon invests heavily in carbon removal technologies. The global economy needs to suck at least a trillion tons of CO₂ out of the atmosphere by 2100. The fund has positioned itself as a leading investor in Direct Air Capture (DAC) and carbon removal. 3. Buying More Time - As climate impacts accelerate (rising temperatures, wildfires, droughts, storms), the firm also invests in climate adaptation and resilience technologies, including geoengineering solutions to potentially cool the planet if carbon removal breakthroughs don't arrive fast enough. Portfolio Strategy & Scale Lowercarbon Capital manages approximately $2.4 billion in assets under management across multiple funds, making it one of the largest climate-focused venture capital firms globally. The firm has invested in 207+ companies across its portfolio, demonstrating a substantial and diversified approach to climate tech investing.
