What is the current emissions gap under NDCs?

UNEP Emissions Gap Report 2023: current NDC pledges would limit warming to 2.5°C by 2100. Conditional NDCs: 2.4°C. Current policies (no new pledges): 3.0-3.2°C. To limit to 1.5°C, global emissions need to fall 43% by 2030 from 2019 levels. Current trajectory: only ~5-10% reduction.

What is the difference between 1.5°C and 2°C global warming?

IPCC SR1.5: At 1.5°C, 70-90% of coral reefs decline. At 2°C, 99% lost. At 1.5°C, Arctic ice-free summer once per century. At 2°C, once per decade. Sea level rise: 0.1m less at 1.5°C. Each 0.5°C difference has nonlinear ecosystem and economic impacts.

Can technology alone close the emissions gap?

Technology is necessary but insufficient without policy. IEA Net Zero by 2050 report: 90% of required reductions from technologies already commercially available or near-commercial. The gap is deployment speed and policy ambition, not technological availability.
