carbon budget

the carbon budget is the amount of greenhouse gases that humanity can emit into the atmosphere by the end of this century and still limit the global temperature increase compared to the pre-industrial levels (1850-1900). according to the ipcc, the atmosphere can absorb, calculated from the beginning of 2020, no more than 400 gigatonnes (Gt) of CO2 if we are to stay below the Paris agreement 1.5°C thresholds.

annual emissions of CO2 – from burning fossil fuels, industrial processes and land-use change – are estimated to be 42.2 Gt per year, the equivalent of 1,337 tonnes per second. At current emissions rates, the budget for staying below the 2°C thresholds would be exhausted in about 25 years. The concept of the carbon budget is based on an almost linear relationship between cumulative emissions and temperature rise. our planet would not be 1.5⁰C warmer precisely when the remaining carbon budget for staying below the 1.5⁰C threshold is exhausted because the momentum over the past 100 of accumulated emissions still have to be absorbed.
by 2031 current estimates show we will be 1.8°C

“The sustainability in mind learning opened my mind to what I thought I knew. From the basic principles of climate change and its impact, to the social dynamics that have led us to where we are today. The course enabled me to reassess what it means to be a leader and it has given me confidence and motivation to initiate change.”
Helen Stephens – social entrepreneur and city councillor

“The carbon calculation process carried out by Carbon Happy World has been a fascinating and eye opening project for me. It provided essential insights into the sources and reasons behind our carbon emissions. The work has already enabled productive engagement with our suppliers to minimise environmental impact"
