![Benchmark emission levels for 2025 and 2030 consistent with the below 2°C limit and the 1.5°C limit](https://ca1-clm.edcdn.com/publications/_c400x565/ca_briefing_benchmark_emissions_1p5_and_2oc_2020_2025_2030_20150210_final_bh_may.pdf-7288.jpg?v=1706738379)
Briefings
This briefing paper analyses the available information in the 2014 UNEP Emissions Gap Report 2014 (‘EGR’) and the IPCC AR5 to produce recommended benchmark emission levels for 2020, 2025 and 2030.
![Zero emission targets as long-term global goals for climate protection](https://ca1-clm.edcdn.com/publications/_c400x565/Rogelj_2015_Environ._Res._Lett._10_105007.pdf-76265.jpg?v=1706738379)
Peer-reviewed Papers
Confusion remains about concepts like carbon neutrality, climate neutrality, full decarbonisation, and net zero carbon or net zero greenhouse gas emissions. Here we clarify these concepts.
![Timetables for zero emissions and 2015 emissions reductions: state of the science for the ADP agreement](https://ca1-clm.edcdn.com/publications/_c400x565/ca_briefing_timetables_for_zero_emissions_and_2050_emissions_reductions.pdf-7290.jpg?v=1706738379)
Briefings
This briefing note outlines suggested time frames for reaching zero global CO2 and total greenhouse gas emissions for ‘below 2°C’ and ‘below 1.5°C by 2100’.
![Is it possible to return warming to below 1.5°C within this century?](https://ca1-clm.edcdn.com/publications/_c400x565/climate_analytics_briefing_is_it_possible_to_return_warming_to_below_1_5degc_within_this_century-.pdf-7469.jpg?v=1706716955)
Briefings
Small island states and the least developed countries have called for warming to be brought back to below 1.5° by 2100. The 1.5°C warming limit is now under review for consideration next year by the UNFCCC.
![Below 2°C or 1.5°C depends on rapid action from both Annex I and non-Annex I countries](https://ca1-clm.edcdn.com/publications/_c400x565/cat_bonn_policy_update_jun2014_2.pdf-7394.jpg?v=1706698123)
