Cambridge Researchers Develop Framework for Long-Term Carbon Removal Portfolio Management

Researchers have created a new risk management approach for carbon removal portfolios that could help stabilize global temperatures over centuries. The study shows nature-based solutions like tree planting can play significant roles when balanced with technological approaches and proper buffers.

New Framework for Carbon Removal Portfolio Management

Researchers from Cambridge University have developed a groundbreaking method to assess whether carbon removal portfolios can effectively limit global warming over centuries, according to reports published in the journal Joule. The approach distinguishes between buying credits to offset risk versus claiming net-negative emissions and provides portfolio managers with tools to evaluate long-term climate stabilization potential.

Record CO2 Surge in 2024 Signals Weakening Planetary Carbon Absorption

Atmospheric carbon dioxide concentrations surged by a record 3.5 parts per million in 2024, reaching 423.9 ppm according to UN data. Scientists report worrying signs that the planet’s natural carbon absorption systems may be weakening amid ongoing high emissions.

Unprecedented CO2 Increase Recorded

The global average concentration of carbon dioxide surged by a record 3.5 parts per million between 2023 and 2024, reaching 423.9 ppm according to reports from the World Meteorological Organization. This represents the largest annual increase since modern measurements began in 1957 and significantly exceeds the previous year’s increase of 2.3 ppm.
