The Centre for Environmental Rights (CER) submitted comments to the South African Department of Environmental Affairs (DEA) on June 15, 2018, regarding the operationalisation of the post-2020 mitigation system. The CER advocates for greater transparency in greenhouse gas (GHG) reporting, opposes the use of historical emissions for carbon budgeting, and argues against the inclusion of new coal-fired power stations in national energy plans.

This briefing paper evaluates three global mitigation pathways—the 1.5°C marker, the 2°C marker, and the G8 marker—against the carbon budgets provided in the IPCC Fifth Assessment Report to determine their likelihood of limiting global surface temperature increases to 2°C by the end of the century.

This briefing by the Stockholm Environment Institute assesses three global mitigation pathways—the 1.5°C marker, the 2°C marker, and the G8 marker—against the carbon budgets provided in the IPCC Fifth Assessment Report (2013). The analysis concludes that only the highly ambitious 1.5°C pathway has a high probability of limiting global warming to below 2°C, while the 2°C and G8 pathways carry significantly higher risks of exceeding that threshold than previously estimated.
