The science is clear about how to prevent increasingly dangerous and irreversible climate change impacts: Limit global temperature rise to 1.5 degrees C (2.7 degrees F), which means cutting GHG emissions in half by 2030 and reaching net-zero CO₂ emissions by mid-century.

While countries, companies, cities and investors have announced some encouraging commitments to help achieve this global goal, they’re far short of what’s needed. Worse still, new research shows the world’s highest-emitting sectors — power, buildings, industry, transport, forests and land, and food and agriculture — aren’t acting anywhere near fast enough.
